used successfully in the sticky1 root-filled soil of the prairie4 ,it was called a steel plow4 ,actually1 it appears that only the cutting edge1 the share1 on the first ,deere plows was steel4 ,the moldboard was smoothly ground wrought iron4 ,deere's invention succeeded because1 as the durable steel share of the plow cut through the heavy earth1 the sticky soil could find no place to cling on its polished surfaces4 ,americans moving westward in the beginning of the #aith century soon encountered the prairie lands of what we now call the ,middle ,west4 ,the dark fertile soils promised great rewards to the farmers settling in these regions1 but also posed certain problems4 ,first was the breaking of the tough prairie sod4 ,the naturalist ,john ,muir describes the conditions facing prairie farmers when he was a boy in the early #ahej's as he tells of the use of the big prairie-breaking plows in the following words3#a ,they were used only for the first ploughing1 in breaking up the wild sod woven into a tough mass1 chiefly by the cord-like roots of perennial grasses1 reinforced by the tap roots of oak and hickory bushes1 called grubs1 some of which were more than a century old and four or five inches in diameter4444 ,if in good trim1 the plough cut through and turned over these grubs as if the century-old wood were soft like the flesh of carrots and turnips2 but if not in good trim the grubs promptly tossed the plough out of the ground4 ,the second and greater problem was that the richer lands of the prairie bottoms1 after a few years of continuous cultivation1 became so sticky that they clogged the moldboards of the plows4 ,clogging was such a factor in prairie plowing that farmers in these regions carried a wooden paddle solely for cleaning off the moldboard1 a task which had to be repeated so frequently that it seriously interfered with plowing efficiency4 ,it seems probable that by the #ahcj's blacksmiths in the prairie country were beginning to solve the problem of continuous cultivation of sticky prairie soil by nailing strips of saw steel to the face of wooden moldboard of the traditional plows4 ,figure #a is a photograph of an #ahth century ,new ,england plow in the collection of the ,u4 ,s4 ,national ,museum4 ,this is one type of plow which was brought west by the settlers4 ,it contributed to the development of the prairie breaker shown in figure #b4 ,the first plow on record with strips of steel on the moldboard is attributed to ,john ,lane in ,chicago in #ahcc4b ,steel presented a smoother surface which shed the sticky loam better than the conventional wooden moldboards covered with wrought iron1 or the cast iron moldboards of the newer factory-made plows then coming into use4 ,it is generally accepted as historical fact that ,john ,deere made his first steel plow in #ahcg at ,grand ,detour1 ,illinois4 ,the details of the construction of this plow have been variously given by different writers4 ,ardrey#c and ,davidson#d describe ,deere's original plow as having a wooden moldboard covered with strips of steel cut from a saw1 in the manner of the ,john ,lane plow4 ,sidebar3 ,,the ,,author3 ,edward ,c4 ,kendall is curator of agriculture1 ,museum of ,history and ,technology1 in the ,smithsonian ,institution's ,united ,states ,national ,museum4 ,in recent years the #ahcg ,deere plow has been pictured quite differently4 ,this has apparently come about as the result of the discovery of an old plow identified as one made by ,john ,deere at ,grand ,detour in #ahch and sold to ,joseph ,brierton from whose farm it was obtained in #aija by the maker's son1 ,charles ,h4 ,deere4 ,he brought it to the office of ,deere ,company at ,moline1 ,illinois1 for preservation and display4 ,this plow is shown in figures #g and #i4 ,in #aich ,deere ,company presented it to the ,u4 ,s4 ,national ,museum1 where it is on display4 ,it can be seen that the moldboard is made of one curved diamond-shaped metal slab4 ,this plow bottom conforms to the description of the diamond plows manufactured by ,deere in the #ahdj's4#e ,the ,company states that according to its records1 this was one of three plows made by ,deere in #ahch and that it was probably substantially identical with the first one made in #ahcg4f ,it may be difficult to prove that the ,museum's specimen was made in #ahch1 but a comparison of this plow 7fig4 #g7 with the #ahdg moldboard 7fig4 #e7 and the #ahee plow 7fig4 #f7 suggests that the ,museum's plow is the earliest of the three1 since there is particularly evident an evolution of the shape of the moldboard from a simple1 almost crude form to a more sophisticated shape4 ,illustration3 ,figure #a4--,,new ,,england ,,strong ,,plow1 ,,mid-#ah,,th ,,century4 ,colter locked into

claims that ,leonard ,andrus1 the founder and leading figure of ,grand ,detour and part owner of the sawmill1 conceived the design of the plow and employed ,deere1 the blacksmith newly arrived from ,vermont1 to build it4 ,this idea may have originated with and was certainly promoted by the late ,fred ,a4 ,wirt1 as advertising manager of the ,j4 ,i4 ,case ,company4 ,it is difficult1 at this distance1 to determine the parts played at the beginning by ,deere and ,andrus4 ,illustration3 ,figure #b4--,,large ,,prairie-,,breaking ,,plow1 ,,mid-#ai,,th ,,century4 ,wheels underneath the beam

the long1 gently curving moldboard turns over unbroken4 ,the earliest existing partnership agreement involving ,andrus and ,deere is dated ,march #bj1 #ahdc4i ,the existing copy is unsigned1 but its conditions are the same as those in the agreements executed during the next few years4 ,it began by stating that ,deere and ,andrus had agreed to become copartners together in the art and trade of ,blacksmithing1 ploughmaking and all things thereto belonging at the said ,grand ,detour1 and all other business that the said parties may hereafter deem necessary for their mutual interest and benefit 444 ,one of the terms was that the copartnership should continue from the date of the agreement under the name and firm of ,leonard ,andrus4 ,a second agreement dated ,october #bf1 #ahdd1aj which brought in a third partner1 ,horace ,paine1 described the business as the art and trade of ,blacksmithing ,plough ,making ,iron ,castings and all things thereto belonging 444 and stated that the copartnership should be conducted under the name and firm of ,l4 ,andrus and ,co4 ,the third agreement1 dated ,october #bj1 #ahdf1 in which another man appeared in place of ,paine1 gave the name of the firm as ,andrus1 ,deere1 and ,lathrop4#aa ,this carried an addendum dated ,june #bb1 #ahdg1 in which ,andrus and ,deere bought out ,lathrop's interest in the business and agreed to continue under the name of ,andrus and ,deere4 ,this is the only mention of the firm of ,andrus and ,deere4 ,it could only have lasted a few months because it was in #ahdg that ,deere moved to ,moline and established his plow factory there4 ,illustration3 ,figure #c4--,,reconstructions ,,of ,,john ,,deere',s #ahcg ,,plow4 ,for a discussion of the position and attachment of the handles see p4 #bd4 7,deere ,company photo47 ,these agreements suggest that ,leonard ,andrus was the capitalist of the young community of ,grand ,detour1 as well as its founder4 ,the dominance of the name ,andrus tends to back up the opinion which holds that ,andrus was the leading figure in the development of the successful prairie plow4 ,on the other hand1 the general tone of the agreements suggests that two or more people were participating in an enterprise in which each contributed to the business and shared in the results4 ,deere contributed his plow and his blacksmith shop1 tools1 and outbuildings2 ,andrus contributed money and business experience4 ,there is no indication that they were formally associated prior to the agreement of ,march #bj1 #ahdc4 ,an advertisement 7it is quoted later7 dated ,february #c1 #ahdc1 and appearing in the ,march #aj1 #ahdc1 issue of the ,rock ,river ,register1 carries an announcement by ,john ,deere that he is ready to fill orders for plows1 which he then describes4 ,there is no mention of ,andrus or of an ,andrus and ,deere firm4 ,i am inclined by the evidence to the view that ,deere worked out his plow by himself1 began to manufacture it in small numbers1 needed money to enlarge and expand his operations1 and went to the logical source of capital in the community1 ,leonard ,andrus4 ,in support of this view ,i quote a statement by ,mr4 ,burton ,f4 ,peek#ab who has spent most of his life in ,deere ,company and who may now be the only person living who knew ,john ,deere3 ,andrus removed to ,grand de ,tour from some place in ,new ,york ,rochester1 though originally from ,vermont4 ,some years later ,john ,deere came along from ,rutland1 ,vermont leaving his family behind him4 ,whether ,deere ever heard of ,andrus or ,andrus of ,deere no one knows4 ,having decided to remain in ,grand de ,tour1 ,deere sent for his family asking my paternal grandfather1 ,william ,peek1 to bring them and also the ,peek family out to ,grand de ,tour4 ,this was done via covered wagon the journey occupying some six weeks4 ,my father1 ,henry ,c4 ,peek1 was then an infant age six weeks and ,charles ,deere1 the son of ,john1 an infant of about the same age4 ,of course these infants came along sleeping in the feed box of the wagon4 ,my grandfather took up land adjacent to ,grand de ,tour and ,john ,deere continued in the manufacturing business4 ,incidentally1 ,john ,deere and ,william ,peek were brothers-in-law having married sisters and what ,i have said1 and much more that ,i might say to you1 is based upon what ,i have been told by my grandfather1 by ,john ,deere and by others who had a part in the early history of the company4 ,so far as ,i know1 ,i am the only living person who ever knew or saw ,john ,deere4444 444 ,i joined the ,deere ,company on ,october #a1 #ahhh1 at the age of #af and retired on the #bhth of ,april1 #aief--nearly #fh years4 ,c4 ,h4 ,deere was my great friend and benefactor4 ,i was educated at his expense as a lawyer and practiced for thirteen years4 ,during this time ,i was his personal attorney1 ,i drew his will1 was made trustee thereunder1 and probably was more intimate with him than any living person4 ,i have seen and read the manuscript of an early history of the company which he wrote1 but never published and there was nothing in it to indicate that ,andrus had any part in the manufacture of the first successful steel plow and it is my firm belief that he had no part other than perhaps a friendly interest in it4 ,,the ,,first ,,plow ,most writers describe ,deere cutting a diamond-shaped piece out of a broken steel mill saw4 ,there is usually no further identification of the type of saw beyond the statement that it came from the ,andrus sawmill4 ,neil ,clark1 author of a brief biography of ,john ,deere1 states that the diamond-shaped piece was cut out of a circular saw4#ac ,there is no evidence given to support this4 ,there are some powerful arguments against it4 ,the circular saw1 especially of the larger size1 was probably not very common in ,america in the #ahcj's4 ,although an ,english patent for a circular saw was issued in #aggg the first circular saw in ,america is attributed to ,benjamin ,cummins of ,bentonsville1 ,new ,york1 about #ahad4ad ,illustration3 ,figure #d4--;,,how ,,deere ,,probably ,,cut ,,and ,,bent ,,the ,,flat ,,plate of his #ahch plow to form the moldboard and landside4 ,because of the shape of the moldboard it became known as the diamond plow4 ,illustration3 ,figure #e4--,,moldboard ,,of #ahdg ,,john ,,deere ,,plow1 showing how the diamond shape of the original design has been slightly modified4 7,deere ,company photo #egaib-;,d47 ,in a small1 new1 pioneering community it seems unlikely that the local sawmill would have been equipped with the newer circular saw rather than the familiar up and down saw which remained in use throughout the #aith century and1 in places1 well into the #bjth century4 ,the up and down saw was a broad strip of iron or steel with large teeth in one edge4 ,driven by water power it slowly cut large logs into boards4 ,it is doubtful that the circular saws of that period were large enough for this kind of mill work4 ,the second argument is the shape of the moldboard itself4 ,the photograph of the #ahch plow in figure #g shows that the shape of the moldboard is unconventional4 ,it is essentially a parallelogram curved to present a concave surface to the furrow slice and thus to make a simple1 small but workable plow4 ,a parallelogram or diamond would be an easy shape to cut out of a mill saw with the teeth removed4 ,the moldboard on the #ahch plow is from 4#bbh to 4#bch inches thick and its width is #ab inches4 ,these dimensions approximate those given in an #ahig ,disston catalog#ae which describes mulay saws1 a type of mill saw1 from #aj to #ab inches wide and from #d to #i gauge4 ,gauge number #d is the thickest and is 4#bch inches4 ,examination of the #ahch plow suggests that ,deere cut the moldboard and landside as one piece1 which was then heated and bent to the desired form4 ,the pattern of this piece is shown in figure #d4 ,some additional metal appears to be forged into the sharp bend at the junction of the moldboard and the landside apparently to strengthen this part1 which may have begun to open during the bending4 ,if1 however1 ,deere had used a large circular saw with plenty of room for cutting out a moldboard of the usual shape and size1 it seems likely that he would have made a plow of more conventional appearance4 ,in any event his moldboard of one jointless piece of polished metal would scour better than one of wood covered with strips of steel since the nailheads and the joints between the strips would provide places for the earth to stick4 ,illustration3 ,figure #f4--,,the ,,shape ,,of ,,the ,,moldboard continued to evolve1 as illustrated by this #ahee ,john ,deere plow4 7,deere ,company photo #egaib-;,a47 ,a very great majority of writers describing ,john ,deere and his plow attribute his fame to his development of a successful steel plow which made cultivation of rich prairie soil practical4 ,the emphasis is always on the development of a steel moldboard and the assumption is that from the #ahcg plow onward stretched an unbroken line of steel moldboard plows4 ,an advertisement for ,john ,deere plows in the ,march #aj1 #ahdc1 issue of the ,rock ,river ,register1 published weekly in ,grand ,detour1 ,illinois1 gives a detailed description1 here presented in full3 ,john ,deere respectfully informs his friends and customers1 the agricultural community1 of this and adjoining counties1 and dealers in ,ploughs1 that he is now prepared to fill orders for the same on presentation4 ,the ,moldboard of this well1 and so favorably known ,,plough1 is made of wrought iron1 and the share of steel1 #e_/af of an inch thick1 which carries a fine sharp edge4 ,the whole face of the moldboard and share is ground smooth1 so that it scours perfectly bright in any soil1 and will not choke in the foulest of ground4 ,it will do more work in a day1 and do it much better and with less labor1 to both team and holder1 than the ordinary ploughs that do not scour1 and in consequence of the ground being better prepared1 the agriculturalist obtains a much heavier crop4 ,the price of ,ploughs1 in consequence of hard times1 will be reduced from last year's prices4 ,grand ,detour1 ,feb4 #c1 #ahdc4 ,this raised two questions3 ,why1 and for how long1 was wrought iron used for the moldboards of the ,deere plows8 ,of what material is the moldboard of the #ahch plow made8 ,during the first few years1 when production was very small1 there were probably enough worn out mill saws available for the relatively few plows made4 ,as production increased this source must have become inadequate4 ,ardrey gives the following figures for the production of plows by ,deere and ,andrus3#af #ahci1 #aj plows2 #ahdj1 #dj plows2 #ahda1 #ge plows2 #ahdb1 #ajj plows2 #ahdc1 #djj plows4 ,ardrey states further that by this time the difficulty of obtaining steel in the quantity and quality needed had become a serious obstacle in the way of further development4 ,the statement1 quoted above1 that the moldboard was of wrought iron and the statistics on production of plows during the #ahdj's and #ahej's belie ,ardrey's claim that it was a serious obstacle1 nor is there any suggestion in the advertisement that wrought iron was being substituted for steel4 ,in #ahdg ,john ,deere amicably severed relations with the firm of ,andrus ,deere and moved to ,moline1 ,illinois1 to continue plow manufacturing in a site that had better transportation facilities than ,grand ,detour4 ,the new firm produced #gjj plows in the first year1 #afjj in #ahej1 and #aj1jjj in #aheg4ag ,swank#ah states that the first slab of cast plow steel ever rolled in the ,united ,states was in #ahdf and that it was shipped to ,john ,deere of ,moline1 ,illinois4 ,a little later he says that it was not until the early #ahfj's in this country that several firms succeeded in making high grade crucible cast steel of uniform quality as a regular product4 ,illustration3 ,figure #g4--;,,john ,,deere',s #ahch ,,plow1 ,,right ,,side1 showing large iron staple used to fasten end of right handle to the standard4 ,note remains of wooden pin near rear end of plow beam4 7,cat4 no4 ,f#aaaa2 ,smithsonian photo #dbfci-;,a47 ,based on a visit to ,deere's factory in #aheg the ,country ,gentleman#ai gave the yearly output as #ac1djj plows4 ,it pictured four of seven models and stated1 these are all made of cast steel1 and perfectly polished before they are sent out1 and are kept bright by use1 so that no soil adheres to them4 ,the article then gives the tonnages of iron and steel used by the ,deere factory in a year4 ,they are as follows3 #ej tons cast steel1 #dj tons ,german steel1 #ajj tons ,pittsburgh steel1 #ge tons castings1 #bjj tons wrought iron1 #h tons malleable castings in clevises1 etc4 ,in addition #ajj1jjj plow bolts and #bjj1jjj feet of oak plank were used4 ,these figures do not indicate what the different parts of the plows were made of but1 if approximately correct1 they do show that more than half the metal used was iron rather than steel4 ,steel accounts for #aij tons2 wrought iron for #bjj4 ,although it is conceivable1 under this weight distribution1 that the shares and moldboards were made of steel while the landsides and standards were made of wrought iron1 other distributions are also possible1 and it is quite conceivable that at this period some of the plows had steel moldboards while others had wrought-iron ones4 ,an analysis of the metal in different parts of an #ahee ,john ,deere plow1 now at the factory in ,moline1 may shed some light on this1 but from these figures and dates it seems likely that most of ,john ,deere's plows during the #ahdj's and #ahej's had wrought-iron moldboards with steel shares4 7,it should be borne in mind that the poorer grades of steel available at this time were probably no more satisfactory than cast iron as far as scouring clean in sticky soil was concerned47 ,illustration3 ,figure #h4--,,reconstruction ,,of ,,deere',s #ahch ,,plow1 right side1 with handles shown in what is believed to be their original position4 7,smithsonian photo #dbfdg47 ,the question of the material in the moldboard of the #ahch plow was answered when a spark-test analysis was made of the metal in the moldboard and share4 ,in this test the color1 shape1 and pattern of the spark bursts produced by a high-speed grinding wheel indicate the type of iron or steel4 ,several spots along the edges and back surface of the moldboard were tested4 ,no carbon bursts were seen in the spark patterns1 indicating that the material was wrought iron4 ,the share consists of a piece1 wedge shaped in cross section1 welded on to the lower1 or front1 edge of the moldboard4 ,this was tested at several spots along its sharp edge1 all of which gave a pattern and color indicating that the material was medium high carbon steel4 ,this test was corroborated by a chemical analysis of filings from the moldboard and share in a metallurgical laboratory4 ,a small trace of carbon was found in the moldboard4 ,it may be present as the result of contamination from several sources1 a likely one being the charcoal fire in the forge when it was heated for bending and shaping4#bj ,these tests agree perfectly with the description in the #ahdc advertisement4 ,it seems1 therefore1 that ,deere's success in making plows that worked well in prairie bottom lands depended as much on the smooth surface he produced by grinding and polishing as on the material used4 ,the filing of the edge of the moldboard for the metallurgical test disclosed that the wrought-iron slab consisted of five thin laminations apparently forged together but with separations visible4 ,the length and regularity of the lines of separation seem to preclude their being striations resulting from the fibrous structure of wrought iron4 ,this calls into question the theory that the moldboard and landside were cut from a mill saw1 since it hardly seems likely that a saw would be made of laminated material4 ,the possibility exists that the body of the mill saw might have been made this way1 with a tooth-bearing steel edge welded on1 but there seems little reason for making a saw out of thin laminations4 ,it is also possible that this laminated iron originally had been intended for some other purpose1 such as boiler plate1 and may have been available in rectangular pieces4 ,in making the #ahch plow ,deere followed a pattern 7fig4 #d71 which suggests that he cut it out of such a piece4 ,illustration3 ,figure #i4--;,,john ,,deere',s #ahch ,,plow1 ,,left ,,side1 showing details of construction and relationship of landside to moldboard4 7,cat4 no4 ,f#aaaa2 ,smithsonian photo #dbfci47 ,since the moldboard of the #ahch plow is of wrought iron1 and since this plow is thought to be essentially identical with the first one ,deere made in #ahcg1 it is highly probable that the #ahcg plow also had a wrought-iron moldboard1 a condition which appears to have been the basic pattern for ,john ,deere plows until the middle #ahej's4 ,,why ,a ,,steel ,,plow ,in view of the facts and the probabilities based on them1 how is the legend of the ,john ,deere steel plow to be explained8 ,there are several likely reasons4 ,it is possible that the first plow1 in #ahcg1 was made from a broken steel mill saw4 ,it is also possible that within a few years puddled iron came to be used for the moldboards because of the scarcity of suitable steel1 either in the form of broken mill saws or as plates ordered from foundries in ,america 7the high price of steel imported from ,england made this an impractical source74 ,however1 it seems more likely that it became known as a steel plow owing to the importance ,deere attached to his plows having steel shares1 as shown in his advertisement in #ahdc4 ,a steel share1 tougher than cast iron1 would hold an edge much better than wrought iron1 and ,john ,muir's description of prairie plowing1 quoted earlier1 substantiates the importance of a tough1 sharp share4 ,deere's plows1 probably distinctive by reason of their steel shares1 may have been called steel plows1 in the regions where they were used1 to distinguish them from the standard wooden plows and from the newer cast-iron implements4 ,the term wooden plow has a similar history4 ,for well over #bjjj years in ,europe some plows have been made with iron shares and the rest of the structure wood4 ,plows in #ahth-century ,america were made principally of wood with iron shares1 colters1 and clevises1 and with strips of iron frequently covering the wooden moldboard4 ,these implements were called1 simply1 plows of various regional types4 ,not until the development and spread of the factory-made plows with cast-iron moldboards1 landsides1 and standards did the term wooden plow come into use to differentiate all these plows from the newer ones4 ,subsequently writers have been led to assume that wooden plow meant a plow with no iron parts and consequently to make unwarranted statements about the primitiveness of the #ahth-century implements4 ,a second reason for use of the term steel plow may have developed from the supposition that the moldboards of the first ,john ,deere plows were made of diamond-shaped sections cut from old mill saws1 which later writers seem to have assumed were made of steel4 7,it is probable that from the late #ahej's on ,deere plows had steel moldboards47 ,however1 mill saws of the early #aith century were not necessarily made of steel1 which was then relatively expensive4 ,i have been told of an old mill saw made of wrought iron on which was welded a steel edge that carried the teeth4#ba ,rees' ,cyclopaedia#bb describes saws as being made of either wrought iron or steel1 the latter being preferable4 ,therefore1 it seems most likely that ,deere's plows1 from his first until the middle #ahej's were made with highly polished wrought-iron moldboards and steel shares4 ,,reconstructions ,the remains of the #ahch plow are shown in figures #g and #i4 ,one's curiosity is aroused as to what the plow looked like in its original state1 complete with handles4 ,several full-scale #c-;dimensional reconstructions and a number of sketches of the #ahcg plow have been made4 ,the reconstructions all must have been based on the remains of the #ahch plow1 since they resemble it closely and it is the only surviving plow of this type known4 ,recently ,i received a photograph 7fig4 #c1 right7 of a plow which has been boxed and in storage for many years at ,deere ,company which may be an early ,deere plow4 ,as it appears in the photograph1 the plow looks unconvincing4 ,the handles are fastened by bolts and nuts1 a manner uncommon in ,american plow making in the early #aith century4 ,the shape of the handles is that of stock handles available for small plows and cultivators in such a catalog as ,belknap's4 ,the plow seems very high and weakly braced4 ,there is no logical reason for curving the end of the beam down and cutting it off at a slant if the handles are attached in the manner shown4 ,the edges of the tenon on the upper end of the standard where it goes through the mortise in the beam have been neatly beveled in a manner ,i have never seen before on any other plow4 ,all of this leads me to think that this is an early reconstruction based on the remains of the #ahch plow which it only roughly approximates in proportion and design4 ,another of these reconstructions is shown in figure #c1 left4 ,although superficially like the #ahch plow it varies considerably in its proportions1 in the angular relations of its parts1 and in other details such as the use of iron bolts and nuts in place of wooden pins4 ,all these reconstructions agree in one thing4 ,they show a plow with handles fastened to both sides of the plow beam and standard4 ,during an examination of the #ahch plow it occurred to me that there was no indication of an attachment of a handle on the landside in the same manner as on the furrow side4 ,the position and attachment of the handle in figure #g is clearly indicated by the remains of a wooden pin in the side of the plow beam near the rear end and by the large iron staple1 in the side of the standard1 which must have held the tapered lower end of the handle4 ,figure #h is a sketch showing this handle in position4 ,the landside view of this plow in figure #i shows that the pin did not extend through the beam nor are there marks on the standard to indicate the position of a staple like that on the furrow side4 ,the four holes approximately in line on the standard and beam show where a piece of sheet metal had been nailed to hold the beam and standard in about the right position4 ,the outline of the sheet metal can be seen on the side of the beam4 ,this was removed at the time this examination was made4 ,how was the landside handle attached8 ,w4 ,e4 ,bridges of the ,national ,museum suggests that it might have been attached to the lower side of the standard and the rear end of the plow beam4 ,this seems1 beyond doubt1 to be correct4 ,the wood has deteriorated considerably over the years and the joints are loose1 but1 within the limits of the existing structure1 the plow beam can easily be set in such a position that its sloping rear end lines up with the slope of the underside of the standard4 ,furthermore1 a long bolt runs from the upper part of the moldboard through the standard and projects quite far beyond its lower surface1 as can be seen in figure #g4 ,the end of the bolt is threaded only part way and it has been necessary to put a cylindrical metal spacer on it in order to draw up the nut snugly4 ,this long bolt must originally have passed through the lower end of the handle1 which1 in turn1 was fastened to the end of the plow beam by a tenon on the end of the beam1 now broken off1 passing through a mortise in the handle4 ,this was the common method of fastening the handle to the beam4 ,the square hole in the plow's iron landside 7fig4 #g71 which at first might seem meant for another bolt passing through the lower end of the handle at right angles to the long bolt1 seems too close to the other bolt and to the edges of the handle4 ,it may simply be a first try for the bolt through the bottom of the standard4 ,in this manner the handle would have been strongly attached to the plow frame and1 at the same time1 would have materially helped to make it rigid by forming one side of a triangular structure4 ,figures #h and #aj show what ,i believe to be the correct reconstruction of the #ahch ,deere plow along the lines just described and1 therefore1 the probable appearance of the #ahcg plow4 ,illustration3 ,figure #aj4--,,reconstruction ,,of ,,deere',s #ahch ,,plow1 left side1 showing how left handle is believed to have been attached4 7,smithsonian photo #dbfcg47 ,it should also be noted that it was general practice in making fixed moldboard plows to have the plow beam1 standard1 handle1 and landside 7or sharebeam1 on the old plows7 in the same plane4 ,symmetrical handles branching from both sides of the beam are found on cultivators1 shovel plows1 middle busters1 and sidehill plows where the moldboard is turned alternately to each side4 ,,in ,,summary-- ,the existing evidence1 ,i believe1 indicates that3 #a4 ,the successful prairie plow with a smooth one-piece moldboard and steel share was basically ,deere's idea4 #b4 ,the moldboards of practically all of his plows1 from #ahcg and for about #ae years1 were made of wrought iron rather than steel4 #c4 ,the success of his plows in the prairie soils depended on a steel share which held a sharp edge and a highly polished moldboard to which the sticky soils could not cling4 #d4 ,the importance attached to the steel share led to the plows being identified as steel plows4 #e4 ,the correct reconstruction of the #ahch plow1 and1 by inference1 the #ahcg plow1 is shown in figures #h and #aj1 previous reconstructions being wrong primarily in the position and attachment of the handles4 #f4 ,the ,museum's ,john ,deere
