EXPLANATION OF TEST REPORT

Each tractor is a production model equipped for common usage. Power consuming accessories can be disconnected only when it is convenient for the operator to do so in practice. A d ­ditional weight can be added as ballast if the manufacturer regularly supplies it for sale. T h e static tire loads and the in­flation pressures must conform to recommendations in the T i r e Standards published by the Society of Automotive Engineers.

P R E P A R A T I O N F O R P E R F O R M A N C E R U N S

T h e engine crankcase is drained and refilled with a meas­ured amount of new oil conforming to specifications in the operators manual. T h e fuel used and the maintenance opera­tions must also conform to the published information delivered with the tractor. T h e tractor is then limbered-up for 12 hours on drawbar work in accordance with the manufacturer's pub­lished recommendations. T h e manufacturer's representative is present to make appropriate decisions regarding mechanical ad­justments.

T h e tractor is equipped with approximately the amount of added ballast that is used during maximum drawbar tests. T h e tire tread-bar height must be at least 65% of new tread height prior to the maximum power run.

B E L T O R P O W E R T A K E - O F F P E R F O R M A N C E

Maximum Power and Fuel Consiunption. T h e manufac­turer's representative makes carburetor, fuel pump, ignition and governor control settings which remain unchanged throughout all subsequent runs. T h e governor and the manually operated governor control lever is set to provide the high-idle speed specified by the manufacturer for maximum power. Maximum power is measured by connecting the belt pulley or the power take-off to a dynamometer. T h e dynamometer load is then gradually increased until the engine is operating at the rated speed specified by the manufacturer for maximum power. T h e corresponding fuel consumption is measured.

Varying Power and Fue l Consumption. Six different horse­power levels are used to show corresponding fuel consumption rates and how the governor causes the engine to react to the following changes in dynamometer load: 85% of the dyna­mometer torque at maximum power; minimum dynamometer torque, 5̂ the 85% torque; maximum power, % and % of the 85% torque. Since a tractor is generally subjected to vary­ing loads the average of the results in this test serve well for predicting the fuel consumption of a tractor in general usage.

D R A W B A R P E R F O R M A N C E

A l l engine adjustments are the same as those used in the belt or power take-off tests. I f the manufacturer specifies a dif­ferent rated crankshaft speed for drawbar operations, then the position of the manually operated governor control is changed to provide the high-idle speed specified by the manufacturer in the operating instructions.

Varying Power and Fuel Consumption W i t h Ballast. T h e varying power runs are made to show the effect of speed-con­trol devices (engine governor, automatic transmissions, etc.) on horsepower, speed and fuel consumption. These runs are made around the entire test course which has two 180 degree

turns with a minimum radius of 50 feet. The drawbar pull is set at 3 different levels as follows: (1 ) as near to the pull at maximum power as possible and still have the tractor main­tain the travel speed at maximum horsepower on the straight sections of the test course; (2 ) 75% of the pull at maximum power; and ( 3 ) 50% of the pull at maximum power. Prior to 1958, fuel consumption data (10 hour test) were shown only for the pull obtained at maximum power for tractors having torque converters and at 75% of the pull obtained at maximum power for gear-type tractors.

Maximum Power with Ballast. Maximum power is measured on straight level sections of the test course. Data are shown for not more than 12 different gears or travel speeds. Some gears or travel speeds may be omitted because of high slippage of the traction members or because the travel speed may exceed the safe-limit for the test course. T h e maximum safe speed for the Nebraska Test Course has been set at 15 miles per hour. The slippage limits have been set at 15% and 7% for pneumatic tires and steel tracks or lugs, respectively. Higher slippage gives widely varying results.

Maximum Power Without Ballast. A l l added ballast is re­moved from the tractor. The maximum drawbar power of the tractor is determined by the same procedure used for getting maximum power with ballast. T h e gear (or travel speed) is the same as that used in the 10-hour test.

Varying Power and Travel Speed with Ballast. Travel speeds corresponding to drawbar pulls beyond the maximum power range are obtained to show the "lugging ability" of the tractor. The run starts with the pull at maximum power; then addi­tional drawbar pull is applied to cause decreasing speeds. The run is ended by one of three conditions: (1 ) maximum pull is obtained, (2 ) the maximum slippage limit is reached, or ( 3 ) some other operating limit is reached.
