Raptor SD Clutch Engagement Sudders Machine Violently And Almost Kills The Engine.

I have a Raptor SD60 that is doing a great job thus far. However, that isn't very long since it only has almost 3 hours on it.



During the engagement of the electric clutch, the mower shakes violently to the point of almost killing the motor. Most of which I realize is the rapid pull of the blades on the engine as though brakes were applied. However, how violent is yours is my question.
