FIELD: machine engineering.
SUBSTANCE: when the tractor without load by reducing the fuel flow reaches the engine speed corresponding to maximum torque. Instantly increase the supply of fuel to the maximum. When reaching the rated speed of the engine crankshaft while the tractor acceleration measured the angular acceleration of the distance measuring wheel. Similarly, the angular acceleration of distance measuring wheel is measured while the tractor is accelerating with the agricultural machine. Using formulas derived from the equations of motion of the tractor without load and with the agricultural machine, determine the strength of the resistance of the working machine.
EFFECT: simplifying measurement and reducing labor intensity.
