The results of experimental research work as part of an arable unit MTZ-80 with mounted plow PN-3-35 on sandy loam soil in Belarus in the differential and locked rear axle of cross-axle drive in acceleration mode with a deep plow on the go and pre-recessed plow. Using strain gauges, the torque on the clutch shaft and the axles of the tractor rear axle. An analysis of average and peak values of moments we found that when a blocked drive total points on the semi-axes were 5,9–31,3 % more than the differential drive. Over-loaded on all test conditions was the right half. Maximum points on it were greater than on the left on 4,6–20,3 % at lock off and 12,1–32,5 % when enabled.
The calculations of the strength of the semi-axes tractor for peak and average load were completed.
Research loads on the primary and secondary shafts of the tractor gearbox bearing blocks have not found a significant effect of the differential lock on the load.
