Becauso of the need for adjustments in the organization and operation of grain farms in these regions and in the light of changing economic conditions information with reference to farm organization and farm practice was obtained. The study was made in April, May, r.nd June of 1934 and for the most part applies to the crop year 1933. The field data were obtained by personal interviewswftt* 1,674 farm operators in grain-producing arees of the Northern Great Plains and the Pacific Northwest. The farming areas surveyed as shown in figure 1, are those outlined in United States Depart- ment of Commerce, Bureau of the Census Bulletin "Types of Farming in the United St, tes, 1930". The farmers interviewed g^ve det- iled information on the organization and operation of their farms, such as acreage of wheat and other crops grown; a history of crop yields over a period of ytars; the practices employed in the production of wheat nnd other crops; the numbers and kinds of livestock; the kinds ->nd quantities of livestock products; an inventory of the kinds and quantity of equipment on the farm; the duty of farm machinery and the cost of operating power equipment. As the study aimed to show the methods of growing and harvesting crops particularly *?heat, the sample of farms may show a larger acreage of wheat and a higher proportion of the land in crops than would a county average. No particular effort was nade Tor any other selection, however, and it is believed that the records obtained are typical of grain farms in the typc-of- farming ar^-as studied. 3. In certain sections of the Northern Great Plains, particularly western North Dakota, eastern Montana, and in many eress of South Dakota, conditions of extreme drought prevailed in 1933. 3ecause of the small harvest reported in these drought areas the harvest work done with power equipment was abnormal. The use of equipment in a normal season ratner tnan that reported in 1933 has been used. In mary areas the use of large scale power equipment was common and con- stituted a large part of the farm expense. For this reason a series of reports dealing with farm equipment is being published. The purpose of the present report is to make available to research workers and others, information relative to kind, size, and accomplishment of field implements on representative grain farms. The first part of the report gives numbers and sizes of field implements by type-of-farming areas. The second part of the report shows, the rates at which these implements did. field work when drawn with horses and with tractors. The other publications in the machinery series are: 1. Utilization of tractors and cost of tractor power on grain farms (Northern Great Plains and Pacific Noathwest, 1J33) . 2. Utilization of combined harvester- threshers and cost of harvesting small grains with a combine (Northern Great Plains and Pacific Northwest, 1933) . 3. Cost of operating farm motor trucks on grain farms (Northern Great Plains and Pacific Northwest, 1933). TOPOGRAPH, SOIL, AND TYPE OF FARMING Physical conditions in the type-of-farming areas in the Northern Great Plains, where the study was made, ar favorable to the use of medium to large equipment drawn with tractors. The prevailing topography in the farming areas is level to slightly rolling. The soil types range from sands to clays. Although the proportion of the crop area utilized for the production of different crops varies to a considerable extent in, as well as between, the sever: 1 type-of- farming areas, the agriculture of the region may be classified as a cash grain type o^ farming with '"heat the major crop (table 1). A classification of the crop areas of the region indicates that propor- tionately more of the crop acreage wrs devoted to small grains and summer fallow in central and western Montana and in southeastern Wyoming than in the other type-of-farming are^s studied. In southeastern Wyoming about 15 percent of the crop area was devoted to corn. Here, as well as in Montana, few crops other than small grains were grown. From west to east a rather decided change in cropping practice began to appear. Instead of wheat being alternated with sum- mer fallow, the common practice was to grov\ wheat in combination with corn, oats, and barley, particularly in- western. Minnesota and eastern North and South Dakota, the greatest concentration of corn acreage being in southwestern Minnesota and in central and eastern South Dakota. A considerable potato acreage was grown on some farms in northwestern Nebraska and in western Minnesota.. Otner crops 4.

Conditions in the Pacific Northwest are quite -~-nt in njany resped s in the Northern Great Plains. The soil type is mainly a silt loam whereas the prevailing topography is rollin.' to hilly, '"heat was the principal crop grown* It was alternated with summer fallow, wheat together with summer fallow comprising most of the crop acreage (table 2). Few other crops were grown to any extent except in tyne-of -farming area 55E in eastern Washington, where peas were of considerable importance, and in type-of -farming area 92A in southern Idaho, where the acreage of alfalfa was quite extensive. KINDS AND SIZES OF FIELD EQUIFME The kinds of field implements on farms in the areas surveyed are, of course, ouite closely associated with the kinds of crops grown. In order that the reader may have a clear picture of the kinds and sizes of field implements on these farms, the implements have been classified in detail by type-cf-: i - ing areas. Farmers in these areas have a decided tendency to keep abreast of the changes and improvements that have been made in farm equipment as the changes that have occurred in the implements employed in the harvesting of grain demonstrates. Formerly all of the grain in the Northern Great Plains was harvested with a binder or header and threshed in a stationary thresher. Al- though this method of harvest still prevails in many sections of the Northern Great Plains, there arc areas, notably in Montana, where harvest! ain with the combined harvester-thresher has, for the most part, superseded other har- vesting methods. Because of these changes some of the implements shown in the tables on farm equipment inventories which follow are not in general use. In the Northern Great Plains, plows of the moldboard type were rspre- sented by the greatest numbers. They were common in all areas and for the entire region those with 2-bottoins were the most usual (table 3). This was particularly true in Minnesota and in eastern North and South Dakota where farms for the most pert are of moderate size and where a more or less gene, type of farming prevails. In the more westerly areas where farms arc larger, 3-bottom and 4-bottom. moldboard plows were reported more frequently than smaller sizes. Disk plows were confined almost exclusively to the north central areas of Montana (table 4), and here, although they were included in the farm inven- tory, they were being rapidly displaced by vertical disk plows. 1/ Vertical disk plows were reported in substantial numbers only in the north central areas of Montana and in southeastern Wyoming (table 5). Those of from 8- to 10-foot widths were the predominate sizes. In the Pacific Northwest moldboard plows were common to all areas. Two- and three-bottom plows were the ones in most common use (table 6). Vertical disk plows were not common except in area 56A in Washington, where they were found on about 62 percent of the farms studiod (table 7). 1/ Sometim^:; referred to as wheat land disk alows. 7.

Single- disk harrows of 8-foot widths and double-disk harrows of 10- or 11- foot widths were the most common sizes. In the Pacific Northwest single-disk harrows were not - rted to any extent (table 10). Tandem-disk harrows were reported in appreciable numbers only in areas 56A and 56B of Washington, areas 55H of Oregon and 79 and 56E of Idaho (table 11) . Spike-tooth harrows were reported in substantial numbers in both the Northern Great Plains and in the Pacific Northwest* In both of these regions those of from IS- to 21-foot widths were the most common sizes (tables 12 and 13). Spring-tooth harrows were recorded only for the Northern Great Plains (table 14), and were of minor importance in practically all areas. Duckfoot cultivators in the Northern Great Plains were of minor importance in most areas except Montana (tabic 15). Rod weoders were confined almost ex- clusively to the north central Montana areas and southeaster ming (table 15). The 9-foot field cultivator and the 12-foot weeder were the most usual sizes. Rod weeders were recorded in a "oreciable numbers in all areas of the Pacific Northwest (table 17). The 12-foot machines were the most usual size. Duckfoot cultivators were of minor importance in the Pacific Northwest (table 18). Packers occurred in all areas of the Northern Groat Plains, but were reported in greatest numbers in North Dakota (table 19). Those of 2-?- to 5^- foot width were the most common sizes. In the Pacific Northwest, packers were not found to any extent except in area 56B of Washington and area 79 of Idaho (table 20). Listers and lister cultivators in the Northern Great Plains (table 21) were confined almost exclusively to western South Dakota, northwestern Nebraska, and southeastern Wyoming. The 2-row implement was the most common size. Listers and lister cultivators were not reported in the Pacific Northwest* Disk drills wore the common type of grain drill on farms in the Northern Great Plains and those of 10 or 11 foot widths were the most usual (table 22). Deep-furrow drills were of minor importance except in type-of -farming area 115 of Montana and in southeastern Wyoming (table 23). Press drills were not reported to any extent in any area (table 24) . Grain drills (table 25) were not tabulrted by type in the Pacific North- west, but disk drills were of first importance, followed by hoe drills, with a limited number of shoe, deep-furrow, and press drills. The usual sizes of disk drills were 9 or 10 feet, whereas hoe drills of 10- or 11-foot widths were the most usual. Row planters and row-shovel cultivators (table 26) were reported in sub- stantial numbers in most areas of the Northern Great Plains except in the more westerly areas of Montana where the acreage of row crops is limited. Two-row planters and one-row cultivators were the most usual sizes. These implements were not reported to any extent in the Pacific Northwest (table 27). Potato planters and diggers (table 28) were recorded in the Northern Great Plains in substantial numbers only in northwestern Nebraska and in the upper Red River Valley of Minnesota. The 1-row machine was the most usual size. These implements were not reported on farms in the Pacific Northwest. Grain binders in the Northern Great Plains were reported in substantial numbers in all areas, while headers were confined chiefly to the larger more specialized wheat farms in the more westerly areas (table 29). Eight-foot binders and twelve-foot headers were the most common sizes. Combines were not found to any extent except in the more westerly .areas of the Dakotas and in the areas surveyed in Nebraska,. Wyoming, and Montana (table 30). Those of 12 foot- width were the most usual size. Windrowers were of minor importance (table 31). Grain binders in the Pacific Northwest were reported in substantial num- bers in most areas except those in Idaho whereas headers were not common except in areas 46 and 56A of Washington (table 32). Binders of 6-foot width and head- ers of 1^-foot width were the most usual siz?s (.table 32) . Combines were common to all areas (table 33). Those of. 15-foot width wore the most common size. Row binders occurred in substantial numbers in most areas of Minnesota and North and South Dakota whereas corn pickers wore of minor importance in the Northern Great Plains. Corn nickers occurred in limited numbers in southwestern Minnesota and in certain areas of South Dakota (table 3.4). One -tow machines were the ones in almost universal use. Row binders and corn pickers were not found on farms in the Pacific Northvest.

[ss per day of doing field w ps of differ] sizes whee draw: with horses and with tractors From the standpoint of least tine required to perform different field operations, the implements in use should be those which, under particular soil and topographic conditions, fit the available power unit, whether it be animal power or tractor power. The level to rolling topography which prevails on grain farms in the northern Great Plains, together with farms of relatively large size, particularly adapts the employment of tractor power on field imple- ments to this region. The change from horses to tractors has been a fairly rapid one, and while this change has been taking place, in seme instances, horse- type equipment of improper size and type has been used with tractors. Operators of such equipment cannot hope to equal the performance of other farmers who have implements properly related to their power units. In the Pacific Northwest, where the prevailing topography is rolling to hilly, tractors have not displaced horses on grain farms as a source of power to draw field implements to so large an extent as in the Northern Great Plains, and this, in spite of the fact that the farms are larger than in the Northern Great Plains. In the Pacific Northwest, tractors have been used longer than in the Northern Great Plains. Mainly because of the steeper slopes, track-laying tyoe tractors predominate, and the power employed to draw field implements is more in keeping with the implements in use. The average accomplishment of field implements of most common size, when drawn with horses and with tractors, is shown for the Northern Great Plains in table 37 and for the Pacific Northwest in table 33. There are other cc - blnations of implements and power that differ in size from those shown in these tables, of course, but only those that are in sufficient numbers to give a fairly reliable figure on accomplishment ^er day are shown. Plowing with horses in the Northern Great Plains was confined mainly to 2-bottom or smaller moldboard plows. Larger plows were drawn mainly with trac- tors. A 5-horse team was the most camion source of power used on 2-bot: moldboard plows and the addition of another horse to make a 6-horse team did not result in a greater work accomplishment ->er day. Likewise, an increase in motive power over that supplied by a 15-horsepower tractor on a 3-bottom 14- inch moldboard plow did not result in covering a greater number of acres per 10-Lour day. However, the use of a 20-horsepower tractor instead of a 15- horseocwer tractor with a 4-bottom 14-inch moldboard plow resulted in an in- crease of about 19 percent in acres plowed per 10-hour day. Vertical-disk plows were all drawn with tractors and covered about 3 acres of ground per day per foot of width. With a 10-foot vertical-disk plow drawn with a 15-.:orse- power tractor approximately 17 percent more acres were covered in a 10-hour day than with a 7-foot vertical disk plow drawn with the same power. Plowing in the Pacific Northwest was almost entirely with the moldboard plow. The amount of power used on a given size cf implement was somewhat larger and the number of acres covered per 10-hour day was somewhat smaller than in the Northern Great Plains. The use of an 8-horse team instead of a 6-horse team on a 2-bottom 14-inch moldboard plow did not result in a greater accomp- lishment per 10-hour day. Moldboard plows of 4-bottoms and larger were almost entirely drawn by tractors. The 25-horsepower crawler-type tractor was the most common source of power for 4-bottom and larger moldboard plows. An increase in size of p^ow for this power resulted in an increase in acreage covered per 10-hour day. Single-disk harrows in the Northern Great Plains were drawn almost entire- ly with horses, whereas tandem-disk harrows were largely drawn with tractors. Somewhat more power was used on tandem-disk harrows of a given size than on single-disk harrows but the acreage covered per 10-hour day was practically the same for each type of disk harrow resulting in quite a material saving of time by the use of the tandem disk when it is necessary to disk the land more than once. Disking in the Pacific Northwest was almost entirely with the tandem- disk harrow drawn with horses. The rates of accomplishment were quite comparable With those in the Northern Great Plains. Spike-tooth harrows used in the Northern Great Plains were mainly those of from 15 to 28 feet in width drawn with from 4 to 6 horses, the most common size of outfit being the 20-foot harrow drawn with 4 horses. .For spike-tooth harrows of that size the use of a 6-horse team instead of 4 horses resulted in an increased accomplishment of only 5 percent. For spike-tooth harrows larger than 20 feet, an increase in number of horses resulted in an appreciable increase in acres covered per 10-hour day. Tractors of 10 and 15 horsepower were most commonly used as the motive power for tractor-drawn spike-tooth harrows. The use of the larger trac- tor on a given size of implement did not result in greater accomplishment per day. The usual rate of accomplishment of spike-tooth harrows drawn with horses was approximately 2 acres per day per foot of width whereas that of spike-tooth- harrows drawn with tractors was approximately 3 acres per day per foot of width. Horse- drawn spike-tooth harrows in the Pacific Northwest were mainly' those of from 10 to 32 feet in width and were drawn with from 4- to 8-horse teams. The most com- mon size of implement was the 20-foot harrow drawn with either 6 or 8 horses. The usual rate of accomplishment for horse-drawn spike-tooth harrows was approxi- mately 2 acres per day per foot of width while that of tractor-drawn spike-tooth harrows was approximately 2.5 acres per day per foot of width. Spring-tooth har- rows were of minor importance in both the Northern Great Plains and in the Pacific Northwest. Duckfoot cultivators used in the Northern Great Plains were mainly those of from 7 to 12 feet in width, those of over 8 feet in width being mainly drawn with tractors. Horse-drawn duckfoot cultivators covered approximately 2 acres per day for each foot of width whereas tractor-nropelled implements covered about 3 acres oer day for each foot of width. Weeding with rod or blade weeders in the Pacific Northwest was mainly with horses. The rod weeders in most general use were from 10 to 36 feet in width while blade weeders in general use were from 12 to 36 feet in width. The most common size of horse-drawn rod and blade weeder was one of 12-foot width drawn with either 6 or 8 horses. The use of an 8-horse team instead of 6 horses did not result in a greater accomplishment per 10-hour day. Listing in the Northern Great Plains was mostly with a 2-row implement drawn with tractors. The 2-row lister drawn with a 15-horsepower tractor accom- plished 54 percent more work in a 10-hour day than when drawn with 6 horses. In a few areas of the Northern Great Plains it is a common practice to use small packers behind moldboard plows. Packers 'not used in connection with moldboard plows were mainly those of from 9 to 16 feet in width. They were drawn almost entirely with 4 horses. An increase in width of packers resulted in an increased accomplishment per day but not always in proportion. Planting potatoes in the Northern Great Plains was mainly with a 1-row planter drawn with 2 horses. The use of 4 instead of 2 horses to draw the 1-row planter resulted in 14 percent more acres being covered per 10-hour day. 44. Planting corn in the Northern Great Plains ;:as with 1-, 2-, and 4-row planters but by far the greatest amount of this work was with a S-row planter drawn with 2 horses. Two -row planter?, or- 2 horses accomplished 55 per-* t more work per day than a 1-row planter drawn with the sane power* A 4-row planter propelled with tractor power covered about 195 percent more acres • day than the 2-row machine drawn with 2 horses. Grain drills in use in the Northern Great Plains were mainly those of from 8 to 20 feet in width, the majority being 10-foot disk drills drawn with 4 horses* A change in power from 4 horses to a 10-horsepower tractor to draw the 10-foot drill resulted in a 55 percent increase in acres covered per day. An increase in tractor power over the 10-horsepower tractbor in connection with a 10-foot drill did not result in an appreciable increase in accomplishment per day. Horses were not used with drills of more than 12 feet width. The use of a 20-foot instead of a 12-foot drill drawn with a 15-horsepower tractor resulted in an increase in accomplishment per day of about 40 percent. Grain drills in the Pacific Nor: - west were of the disk, hoe, and shoe type, the majority being disk drills drawn with horses. The use of a 10-foot drill drawn with 4 horses instead of a 6-foot drill drawn with the same power resulted in an increase in accomplishment of approximately 57 percent. Cultivating corn in the Northern Great Plains was with 1-, 2-, and 3-row cultivators. Two-row cultivators drawn with 4 horses covered approximately twice as much acreage per 10-hour day than did 1-row cultivators drawn with 2 horses. Mechanical harvesting of corn was almost entirely with the 1-row binder drawn with horses. Binders of this size drawn with 4 horses did not accomplish more work per day than when a 2-horse team supplied the power* Grain harvesting 'in the Northern Great Plains ?. r as with binders, headers, and combines. Harvesting with the binder was the most common method. Combines ranked second in importance with only a limited acreage harvested with the header. Eight-foot binders and twelve-foot headers and combines were the ones in most common use. The 8-foot binder drawn with a 15-horsepower tractor accom- plished about 40 percent more work in a given time than a binder of the same size drawn with 4 horses. Likewise, a 16-foot combine drawn with a 15-horsepower trac- tor accomplished about 53 percent more work in a given time than a 10-foot combine drawn with the same power. Grain harvesting in the Pacific Northwest was with binders, headers, and combines, but the combine was by far the most common har- vesting method. Horses were utilized to draw these machines to a much larger extent than in the Northern Great Plains and because of a more rugged topography in the Pacific Northwest the accomplishment per 10-hour day for implements of comparable size and drawn by the same power was considerably less than in the Northern Great Plains. Harvesting of hay in both the Northern Great Plains and in the Pacific Northwest was largely with 5-foot mowers and 10-foot sulky rakes drawn with 2 horses. The rate of accomplishment in the Northern Great Plains was approxi- mately 2 acres per 10-hour day for each foot of width while in the Pacific North- west the accomplishment was slightly less. .:..
