 INTRODUCTION 
 
 Successive years of low farm incomes have seriously reduced the resources 
 of many farmers in the spring wheat regions of the Northern Great Plains and 
 of the Pacific Northwest. Because of the need for adjustment in the organ- 
 ization and operation of grain farms in these regions and in the light of 
 changing economic conditions, information with reference to farm organization 
 and farming practice ^as obtained. 
 
 The study was made in April, May, and June of 1^34 and, for the most 
 part, applies to the crop year 1&33. The field data were obtained by personal 
 interviews with 1,674 farm operators in grain producing areas of the Northern 
 Great Plains and of the Pacific Northwest. The farming areas surveyed, shown 
 in figure 1, are those outlined in United States Department of Corirerce, 
 Bureau of the Census Bulletin, "Types of Farming in the United States". The 
 farmers interviewed gave detailed information on the organization and opera- 
 tion of their farms, such as acreage of wheat and other crops grown; a history

 of crop yield? over a period of years; the practices employed in the production 
 of wheat and other crops; numbers and kinds of livestock; kinds and 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 wheat, 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 made for any other selection, however, and it is believed 
 that the records obtained are typical of grain farms in the type-of- farming 
 areas studied. 
 
 In certain sections of the Northern Groat Plains, particularly western 
 North Dakota, eastern Montana, and in many areas of South Dakota, conditions 
 of extreme drought prevailed in 19 33. As a result very little harvest was 
 reported in these drought areas and the harvest work done with power equip- 
 ment was abnormal. The use of equipment in a normal season rather than that 
 reported in 1953 has been used in calculating the cost of operating power 
 equipment. 
 
 In many 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 re- 
 ports dealing with farm equipment is being published. 
 
 The purpose of the present report is to show the extent to which tractors 
 are used for farm power, the type .and size of tractors in use, the kinds of 
 work done and the cost of using tractors on representative farms in the grain- 
 producing sections o^ the Northern Great Plains and of the Pacific Northwest, i 
 The other publications in the machinery series are; 
 
 1. Utilization of combined harvester-threshers and cost of harvesting 
 small grains with a combine (Northern Great Plains and Pacific Northwest, 1933). 
 
 2. Cost of operating .farm motor trucks on grain farms (Northern Great 
 PI a in s and Pac if ic Nor t hues t , 19 33 ) . 
 
 3. Tillage, planting, and harvesting equipment on grain farms and 
 rates of doing field work with these implements when drawn with horse and with 
 tractor power (Northern Great Plains and Pacific Northwest) . 
 
 IJUTffiER AND SIZE OF FARMS HAVING TRACTORS AND NUMBER AND SIZE 
 OF FARMS NOT HAVING TRACTORS BY TYPE- OF -FARMING AREAS 
 
 Tractors were used in all of the grain- producing areas surveyed in the 
 Northern Groat Plains (table 1). They are the chief source of power for 
 field work on many of the larger wheat farms in the more westerly areas. On 
 the smaller general farms in the eastern aroas of the region, horses were 
 used for certain kinds of field work and on many of these farms horses were 
 the only source of power for field work. The proportion of farmers using 
 tractors, according to this sample, varied from 25 percent in a general farming

 area of Minnesota to 100 percent in one of the wheat areas of Mont aim. In 
 Minnesota and in the eastern part of North Dakota and South Dakota about 50 
 
 rcent of the farms had tractors; in the central and western parts of the 
 Dakotas, about 70 percent; and in Montana, northeastern Wyoming, and north- 
 western Nebraska about 80 percent were tractor farms. For the entire region 
 69 percent of the farmers enumerated used tractors whereas 31 percent did not. 
 In all areas the crop acreage per farm on farms where tractors were used 
 exceeded the crop acreage on farms using only horses for field work. Because 
 of the tendency toward the greater use of tractor power in the areas of large 
 wheat farms the crop acres per farm averaged 120 percent larger on farms 
 having tractors than on farms not having tractors. 
 
 In the Pacific Northwest, tractors were used in all areas but the 
 number of non-tractor farms in most areas exceeded the number of farms having 
 tractors (table 2). For the region as a whole, 42 percent of the farm 
 operators used tractors whereas 58 percent did not. The average crop acreage 
 per farm was 95 percent larger on farms having tractors than on non-tractor 
 farms. Farms having tractors as well as no n- tractor farms in this region 
 are larger than farms in the Northern Great Plains. In addition, the pro- 
 portion of farms not having tractors to those reporting tractors far exceeds 
 that of the Northern Great Plains. This is largely due to the fact that the 
 topography of much of thes crop area of the Pacific Northwest is very rolling 
 which makes a tractor, especially the high-wheel type, less adapted for field 
 work than on the level, to slightly rolling crop land that prevails in the 
 Northern Great Plains.

CROPS PRODUCED ■ TRACTORS A] ID SIZE 
 
 Or 0F.3 BY 
 
 In the Northern Great Plains cr farms where tractors were used, the pro- 
 portion of the crop area utilized for the production of different crops varied 
 to a considerable ex-cent in, as well as between, different type-c: - ing 
 
 areas. The agriculture of the region, however, may be classified as primarily 
 
 sash grain type -of -farming with wheat the major crop. An examination of 
 table 7, shows that proportionately more of the total crop area was devoted to 
 wheat and summer fallow in central and western Montana ani northeastern 
 Wyoming than in the other areas studied. In northeaster:. ; about 15 
 
 percent of the crop area was devoted to corn. Proceeding eastward a rather 
 decided change in cropping practice began to appear. Instead of alternating 
 wheat with summer fallow the common practice was to grow wheat in combination 
 with corn, oats, and barley. In eastern Montana and northwestern and north 
 central North Dakota, wheat was the principal crop grown, with moderate 
 acreages of oats, barley, and corn. These crops and summer fallow accounted 
 for most of the crop acreage. In southwestern Na - i Dak( . ©stern South 
 Dakota, and northwestern Nebraska, wheat v/as still Lhe dominant crop but the 
 acreage devoted to corn, oats, and barley showed a considerable increase over 
 that of eastern Montana and northwestern and north central North Dakota. In 
 south central North Dakota and central South Dakota wheat still held first 
 rank but acreages of oats and barley and especially corn in central South 
 Dakota were of increasing importance. In eastern North Dakota and South 
 Dakota and western Minnesota wheat occupied from 20 to 50 percent of the crop 
 area with barley, oats, and corn making up most of the balance. The greatest 
 concentration of corn acreage was in eastern South Dakota and southwestern 
 Minnesota. In addition sweet clover, alfalfa, and flax were of considerable 
 importance in western Minnesota and on some farms potatoes were produced on 
 a commercial scale. 
 
 In the northern Great Plains tractors of 15-to 17-drawbar horsepc 
 of the ordinary high-wheel typo were the most common and were followed in 
 order by those of 8-to 12-drawbar horsepower. General purpose tr tars of 
 9-to 12-drawbar horsepower were quite common in those areas of South Dakota 
 and Nebraska where row crops were grown to a considerable extent. Tractors 
 of the track-laying type were reported only in Montana. 
 
 In the Pacific Northwest wheat for grain was the principal crop, table 
 4. It was alternated with summer fallow. Wheat, together with summer fallow, 
 comprised most of the crop acre;. ; -.pt in area 56B in eastern Washington, 
 
 re peas were of considerable importance, area 74 in eastern 7/ashington 
 ro oats were grown to a considerable extent, and area 92A in southern 
 Idaho where the acreage in alfalfa was quite large. 
 
 Tractors in the Pacific Northwest wore considerably larger than those 
 in the Northern Great Plains. Because of the rolling topography the track- 
 ing type of tractor v/as the one in common use. Those of 85- ir horse- 
 po re the most common size. A few high- wheel tractors were in use, 
 especially on farms where the topography irly level. Where high-wheel 
 tractors ware used those of 15-drawbar horseuower were the most common size.

11. 
 
 CROP AREA PER FARM ON FARMS HAVING TRACTORS, AND NUMBER, 
 TYPE, AND SIZE OF TRACTORS 
 
 The number of tractors by size and type according to acreage in crops 
 on farms, reporting tractors, for the Northern Great Plains i3 given in table 5. 
 In this region there did not appear to be any decided relationship between 
 crop acreage per farm and size of tractor. There was some tendency for the 
 larger tractors, especially those of the track-laying type, to bo found on the 
 larger farms but a greater tendency for those farmers who are operators of 
 large acreages to use two or more tractors of medium size rather than to in- 
 vest in the larger tractors. For the most part those farmers with about 400 
 crop acres or less per farm had only one tractor whereas on quite a large 
 percentage of the farms with a crop acreage in excess of this more than one 
 tractor was owned. Fifty-four percent of all tractors enumerated were on 
 farms of 500 crop acres or less, 33 percent were on farms of 501 to 1,000 
 crop acres, and 13 percent were on farms of over 1,000 crop acres. 
 
 In the Pacific Northwest where farms are larger than in the Northern 
 Great Plains, the size of tractor increased somewhat with an increase in crop 
 acreage, but not uniformly, the tendency being to use tractors of medium size 
 regardless of crop acreage (table 6). Twenty-three percent of all tractors 
 represented were on farms of 500 or less crop acres; 30 percent were on farms 
 of from 501 to 1,000 crop acres; and 47 percent were on farms of over 1,000 
 crop acres. 
 
 KINDS OF TRACTOR SQRK AND ANNUAL HOURS OF USE PER TRACTOR 
 
 BY TYPE- OF- FARMING ARE.IS 
 
 The annual use of tractors in these areas is influenced largely by the 
 number of crop acres per farm .and kinds of crops grown. 
 
 In a few instances miscellaneous work performed with tractor power may 
 have been overlooked in recording the work done with tractors on these farms, 
 but for the most part the kinds and amounts of work performed with tractor 
 power are accounted for in work of different kinds by type- of- farming areas 
 as shown in tables 7 and 8. 
 
 A limited amount of tractor work in the Northern Greet Plains consisted 
 of corn shredding, corn shelling, and silo filling. When this work occurred 
 it was recorded as "Corn harvest". Tractors in this region were used almost 
 universally for preparation of seedbed, and to a Large extent, for planting of 
 crops. In addition tractors of the general purpose type wore used quite ex- 
 tensively for cultivation of rov; crops. The harvest work was influenced 
 largely by the method of harvesting the crop. In western Minnesota and in 
 the eastern a nd central areas of North Dakota and South Dakota the work of 
 tractors, except that of preparation of seedbed and planting, was mainly that 
 of harvesting grain with a binder and threshing with a stationary thresher, 
 and corn harvesting, whereas in the other types of farming areas, where 
 harvesting with a combine was a common method and little corn was grown, the 
 use of the tractor except for proharvost work was largely for harvesting and

 threshing grain with a combine, Custom work was of minor importance, being 
 mainly harvesting and threshing grain, either with the combined harvester- 
 thresher or harvesting with a binder and threshing with a stationary 
 thresher. The total work for tractors of all sizes amounted to an annual 
 average of 404 hours per tractor per year of Which 98 percent was home work 
 and 2 percent custom work. 
 
 The work of tractors in the Pacific Northwest was almost entirely that 
 of preparation of seedbed and planting of grain crops and harvesting with a 
 combined harvester- thresher. The total work for tractors of all sizes 
 amounted to an average of 585 hours per tractor per year of which 96 percent 
 was home work and 4 percent was custom work. 
 
 ANIKJAL HOURS OF USE OF TRACTORS OF 
 DIFFERENT TYPES AND SIZES 
 
 In the Northern Great Plains the work of general purpose tractors 
 (table 9) amounted to an average of 458 hours per tractor per year; for or- 
 dinary high- wheel tractors it was 392 hours and for traek-laying tractors, 
 760 hours. The greater annual use of the general purpose tractor as compared 
 with the ordinary high- wheel tractor was mainly accounted for by its use in 
 cultivating row crops. The large number of days of annual use of the track- 
 laying tractor was mainly because of the fact that this type of tractor 'was 
 used almost exclusively on farms of the largest crop acreages.

 In the Pacific Northwest the work of ordinary high- wheel tractors 
 amounted to an average of 373 hours per tractor per year; and for track- laying 
 tractors it was 657 hours per tractor per year, table 10. As in the Northern 
 Great Plains, the lesser amount of work done annually by hi^h-wheel tractors 
 than with track-laying tractors was largely because of the fact that the 
 high-wheel tractor was used principally on the s '.all to medium sized farms.

 The distribution of tractors of different types and sizes in the North- 
 ern Great Plains by hours used annually (table 11) shows that 71 percent were 
 used 500 hours or less; 19 percent were used from 501 to 750 hours; whereas 
 only 10 percent were used over 750 hours per year. In the Pacific Northwest 
 58 percent of the high-wheel tractors were used 400 hours or less; 37 percent 
 were used from 401 to 800 hours and onl^ 5 percent were used rrore than 800 
 hours annually. Thirty-one percent of the track-laying tractors were used 400 
 hours cr less; 43 percent were used 401 to 800 hours and 26 percent were 
 used more than 800 hours annually, table 12. 
 
 COST OF USING TRACTORS 
 
 In presenting this information the various items of cost are treated 
 separately and reported in quantity factors wherever possible, since costs 
 expressed as money units are subject to considerable change especially during 
 periods of wide price fluctuations. The items \iiish have been considered as 
 operating cost are fuels, lubricants, repairs, depreciation, and interest.

 The quantitiP3 and cost of these items per tractor per. year are averages which 
 were computed by dividing the total expense for a given item of cost by the 
 total number of tractors included in the study. The yearly cost divided by 
 the total number of 10-hour days a tractor was used during the year is the 
 average cost of operation per day. The hours of work per tractor per year 
 represents the normal rather than the hours actually used in 1933. 
 
 Tables 14 to 17 give the itemized cost of operating tractors of dif- 
 ferent types and sizes in the Northern G-reat Plains and tables 19 to 22 
 present corresponding data for the Pacific Northwest. The quantities of 
 fuel and cylinder oil shown in tables 13 and 18 are based on the normal 
 annual consumption rather than on the quantities used in 1933. The cost of 
 fuel and lubricants shown in tables 14 and 19 is based on the normal annual 
 consumption of fuel, oils, and grease at prevailing 1933 prices. 
 
 The cash repairs shown in tables 15 and 20 represent normal tractor 
 repair charges rather .than actual expenditures in 1933. The cost of hired and 
 other labor on tractor repairs reflects the normal annual days of labor at 
 prevailing 1933 rates for labor. 
 
 Depreciation as shown in tables 16 and 21 was computed by dividing the 
 first cost of the tractor by the estimated years of useful life. Interest 
 shown in these tables was charged at 6 percent of one-half of the average 
 first cost of the tractor. 
 
 For the ordinary high- wheel tractor in the Northern Great Plains, fuel 
 and lubricants constituted 44.3 percent of the total annual cost of operating 
 tractors; cash repairs, 10.4 percent; hired labor on repairs, 0.1 percent; 
 other labor, 1.7 percent; depreciation, 33.3 percent; and interest, 10. £ 
 percent. 
 
 In the Pacific Northwest the percentage distribution of the total cost 
 for track-laying tractors was as follows: Fuel and lubricants, 47.3 percent; 
 cash repairs, 11.1 percent; hired labor, 0.5 percent; other labor, 1.5 
 percent; depreciation, 30.4 percent; and interest 9.4 percent. 
 
 Tractor operators who have no indebtedness on their tractors may con- 
 sider fuel and lubricants and cash repairs including hired labor on repairs 
 as cash costs and operator and family labor on reorirs, depreciation, and 
 interest as non-cash costs. For tractor operators viho have little if any 
 equity in their tractors the cash outlay vail include practically all 
 expense except operator and family labor on repairs.
