Sample practice questions
Easy
1. What component in a tractor hydraulic system converts hydraulic pressure into a strong linear pushing or lifting force?
A hydraulic cylinder (ram)
The transmission gearbox
The differential
The clutch
Answer: A hydraulic cylinder (ram) — A hydraulic cylinder (ram) converts hydraulic fluid pressure, pushing a piston, into a strong linear (pushing or lifting) mechanical force.
Easy
2. How many lift arms make up the standard 3-point coupling used to attach implements to a tractor?
Two lower lift arms and one upper (top) link
Four lower lift arms and no top link
One lower lift arm and two top links
Three lower lift arms only
Answer: Two lower lift arms and one upper (top) link — The 3-point coupling consists of two lower lift arms and one upper (top) link, arranged in a triangular configuration.
Medium
3. Name the adjustable 3-point coupling component that controls an attached implement's tilt angle relative to the ground.
Answer: top link — The top link is adjustable in length and controls the implement's tilt angle relative to the ground, allowing the correct working angle to be set.
