| Abstract |
The effect of rear tire inflation pressure on the performance of a front wheel assist (FWA) tractor equipped with 18.4R38 radial tires and operating on sandy loam soil was studied. The tractor was instrumented to measure performance parameters such as drawbar pull, dynamic rear wheel load, forward speed, rear wheel speed, and the torque on the rear axle.
The tests were conducted for the tractor when operating in two-wheel drive mode (2WD) at three rear tire inflation pressures (80, 120, and 160 kPa). In general, lower rear tire inflation pressure increased tractive performance.
Nonlinear Regression coefficients were obtained for the dynamic traction ratio and the tractive efficiency of the FWA tractor in 2WD mode. The determenation coefficients and mean squared errors showed that there are highley correlation between field and predicted data at rear wheel slip ranged from 5 to 28 %.
