A tractor clutch brake disc is a component of the clutch system in a tractor. It is responsible for transmitting power from the engine to the transmission by engaging and disengaging the clutch.

Tractor clutch brake discs points


The clutch brake disc serves two main functions in the clutch system. Firstly, it enables smooth engagement and disengagement of the clutch, allowing the power from the engine to be transferred to the transmission when engaged and stopping the power transmission when disengaged. Secondly, it helps to slow down or stop the rotational movement of the transmission input shaft during shifting or stopping operations.


Clutch brake discs are typically made of friction materials such as organic materials, ceramic materials, or a combination of both. These materials provide the necessary friction to engage and disengage the clutch effectively and provide braking action when needed.

Design and Construction

Clutch brake discs are usually round or circular in shape and have a splined center hole that fits onto the transmission input shaft. They may have a smooth or grooved surface to provide improved friction and heat dissipation. The discs are sandwiched between the clutch pressure plate and flywheel, allowing for engagement and disengagement when the clutch pedal is operated.

Wear and Maintenance

Clutch brake discs are subject to wear over time due to the friction and heat generated during clutch engagement and disengagement. Regular maintenance and inspection of the clutch system are necessary to ensure proper functioning. If the clutch brake disc becomes worn or damaged, it may need to be replaced to maintain optimal clutch performance.

Replacement and Compatibility

When replacing a clutch brake disc, it is important to ensure compatibility with the tractor model and clutch system. Different tractor manufacturers and models may have specific requirements regarding the size, thickness, and friction material of the clutch brake disc. It is advisable to consult the tractor manufacturer’s specifications or seek guidance from a qualified tractor mechanic or parts supplier to select the appropriate replacement disc.

Importance of Proper Operation

The proper operation of the clutch system, including the clutch brake disc, is essential for smooth shifting, efficient power transfer, and extended clutch life. Proper clutch pedal operation, avoiding excessive slipping, and avoiding aggressive shifting can help prevent premature wear and damage to the clutch brake disc.

It’s worth noting that specific designs and configurations of tractor clutch brake discs can vary depending on the tractor manufacturer and model. Therefore, consulting the tractor’s service manual or seeking professional advice is recommended for accurate and detailed information related to a specific tractor’s clutch brake disc.
