Question

The function of hydraulics in a machine is

• A. To stop the engine
• B. To change gears
• C. To hitch to a trailer
• D. To lift and lower agricultural implements

Hint:

Hydraulic systems provide powerful lifting and lowering capabilities in agricultural machines.

Answer 1

The Correct Option is D

Hydraulics in machines, especially agricultural machinery like tractors, are used to lift and lower implements such as ploughs, harrows, and seeders. This hydraulic system uses fluid pressure to perform lifting actions, making it easier and more efficient to handle heavy equipment.
- Stopping the engine, changing gears, and hitching to a trailer are functions managed by other mechanical or control systems.
