The clutch disc is the component responsible for transferring power from the engine (crankshaft) to the gearbox (clutch shaft). The disc consists of a splined hub mounted on the clutch shaft and a disc with springs and appropriately thick friction linings. The disc , pressed by the second clutch element, the pressure plate, uses the friction force (the lack of friction during power transfer) of these two elements to propel the tractor. The springs in the clutch discs are responsible for reducing vibrations generated during high engine speeds.

The first signs of clutch disc wear (wear) are clutch slippage, which makes it difficult or impossible to move the vehicle. The tractor fails to accelerate when the engine speed increases. The clutch disc can also show signs of wear if it is contaminated with oil. It is recommended to replace the disc along with the clutch pressure plate and release bearing, as all these components have comparable durability and wear at the same rate. Another sign of clutch disc wear is the inability to engage a gear.
