Tractive Performances of Wheel-Type Tractor (II)

Rotary Tillage Test

Abstract

The rotary tillage tests were performed by using the tractor attached with the rotary tillage apparatus. In the tests, the torques of rotary shaft, clutch shaft, PTO driving shaft and rear wheel axle were measured.
The torque fluctuations of rotary shaft were very large, and the torques of other shafts except the rear wheel axle fluctuated with those of the rotary shaft. But the torques of rear wheel axle decreased as those of the rotary shaft increased, and when the torques of rotary shaft were larger, those of the rear wheel axle were negative, so the tractor was pushed by the resistance of rotary tillage.
