If the clutch is engaged too quickly, what safety device is used to prevent damage to the drive shaft, blower assembly or other parts of the snowblower?
- A.
Shear pin
- B.
Brake pad
- C.
Auto clutch
- D.
Automatic kill switch
Correct Answer
A. Shear pinExplanation
When the clutch is engaged too quickly on a snowblower, the shear pin is used as a safety device to prevent damage to the drive shaft, blower assembly, or other parts. A shear pin is designed to break under excessive force, which helps protect the more expensive and critical components of the snowblower from being damaged. By breaking the shear pin, the excessive force is absorbed and the drive shaft or blower assembly is spared from potential harm. This allows for easier and cheaper replacement of the shear pin instead of having to repair or replace more expensive parts.Rate this question:
