Subtopic: Hitch systems and hitching of tillage implements
Question Statement:
For a 3-point hitch implement in a free-link operation, the depth of cut is primarily controlled by the:
Options:
(A) Tractor hydraulic lift cylinder only
(B) Gage wheel on the implement and the hitch geometry
(C) Top link length adjustment during motion
(D) Draft control sensing spring
Answer Key:
B
Step-by-Step Solution & Explanation
In free-link operation, the hydraulic lift arms are free to float, and the implement relies on its own weight, soil forces, and an implement gage wheel (or runner) along with convergent 3-point linkage geometry to maintain working depth.
