However the majority of tractors have a clutch because it is more durable then a torque converter, and incredibly simple. New tractors commonly have electronics controled clutches and can shift like automatics, some even feel quite similar to hydrostatic of cvt at low speeds because the gears are so close together.
One may also ask, how does a tractor wet clutch work? A wet clutch is immersed in a cooling lubricating fluid which also keeps the surfaces clean and gives smoother performance and longer life. Wet clutches, however, tend to lose some energy to the liquid.
Additionally, how does a clutch work?
In order for a car to stop without killing the engine, the wheels need to be disconnected from the engine somehow. The clutch allows us to smoothly engage a spinning engine to a non-spinning transmission by controlling the slippage between them. A clutch works because of friction between a clutch plate and a flywheel.
How does a clutch burn out?
Burn is a term used for wearing of the clutch plate by friction. This causes the engine to stop with a jerk and eventually, the clutch gets worn away by friction. So, never release clutch pedal rapidly (even at higher gears, release it steadily).
