Subtopic: Selection, operation, maintenance and repair of I.C. engines
Question Statement:
In a walking-type power tiller (two-wheel tractor), steering while operating a rotary cultivator is achieved by:
Options:
(A) A steering wheel connected to a recirculating ball box
(B) Independent left and right dog clutches (steering clutches) on the drive axle
(C) Hydraulic power steering rams
(D) Tilting the rotavator rotor assembly
Answer Key:
B
Step-by-Step Solution & Explanation
Power tillers utilize independent left and right steering dog clutches on the handle grips. Disengaging one clutch disconnects drive power from that wheel, allowing the opposite wheel to pivot the machine.
