For a two-wheel drive tractor, use of differential lock in adverse field condition ensures
Options:
(A) equal distribution of torque to both the drive wheels.
(B) equal distribution of power to both the drive wheels.
(C) distribution of higher amount of torque to the wheel under poor traction.
(D) distribution of higher amount of torque to the wheel under better traction.
Official Answer Key:
D
Step-by-Step Solution & Explanation
An open differential delivers equal torque to both wheels, so the wheel with poor traction spins and limits the torque of both wheels.
Locking the differential ties the two axle shafts together so both rotate at the same speed; torque is then distributed according to available traction.
Consequently the wheel with better traction receives the higher share of torque and the tractor pulls out of the adverse patch.
Distractor (A) describes the unlocked (open) differential — the most common error.
