Using a snowblower on a gravel driveway usually leads to having to replace a shear pin now and again as a rock gets jammed in the augurs. I was thinking would it be better to slightly reduce the throttle, my thoughts on it are:
- It would be less jarring to the engine as it would be turning slower and have less power in the power stroke to fight a rock. Also it may give the rock enough time to move out of the way.
But after thinking about it some more
- Less speed and less power the less the chance the shear pin will shear, which means the engine takes the total hit
Any thoughts, experience on it?
