Subtopic: Hitch systems and hitching of tillage implements
Question Statement:
In a 3-point tractor hitch system, the lower links converge in the horizontal plane such that their virtual hitch point is located $1.2\text{ m}$ ahead of the rear axle. The center of resistance of the mounted plow is located $1.8\text{ m}$ behind the rear axle. If the total draft force is $8\text{ kN}$ directed along the longitudinal centerline, the lateral force on each lower hitch pin due to draft is ________ $\text{kN}$ (answer in integer).
Answer Key:
0
Step-by-Step Solution & Explanation
When the implement draft is collinear with the longitudinal centerline of the tractor, the system is symmetric about the central vertical plane.
The line of draft passes directly through the virtual hitch point on the center axis.
Therefore, no unbalanced lateral force or side draft is generated on the hitch pins (lateral force $= 0\text{ kN}$).
