Question Statement:
The rear furrow wheel in a tractor mounted disc plough is provided to
Options:
(A) reduce the frictional power loss
(B) maintain the uniform depth of cut
(C) reduce the side draft
(D) improve the penetration of the plough
Official Answer Key:
C
Step-by-Step Solution & Explanation
A disc plough, unlike a mouldboard plough, generates a significant lateral (side) force due to the disc's concave, angled working surface. The rear furrow wheel is set to run against the furrow wall and take up this lateral thrust, preventing the plough (and tractor) from being pushed sideways — i.e., it counteracts/reduces the side draft. Answer: (C).
