1.PROBLEM :Clutch slippage.
The initial stage of clutch slippage is very hard to notice,but the following symptoms
1) The tractor is not generating adequate power when performing heavy duty operations.
2) Output is not commensurate to increate in engine speed when the engine is accelerated suddenly
during operation.

These symptoms are apt to be mistaken for engine problems. Clutch slippage that is not repaired will
result in serious damage such as excessive wear of the clutch facing,the clutch cover, and even flywheel
or clutch seizure.
