If the blades aren't rotating, it might be because the deck drive belt is worn, loose, or broken; install a new deck drive belt. Also, check if the deck drive belt is off the pulley, and if so, reinstall it and determine the cause.
Why does my BigDog Alpha MP Lawn Mower circle or veer in one direction?
If your mower circles or veers, it could be due to several reasons. The steering linkage might need adjustment, or it could be loose, so tighten the linkage. Make sure the tires are properly inflated by adjusting the air pressure to 8 - 12 psi (55 - 83 KPa).

To troubleshoot uneven cutting height, start by sharpening the blades or installing new ones if bent. Ensure the deck is level. Adjust the height of the anti-scalp wheels. Clean the underside of the deck, and adjust the air pressure of the tires to 8 - 12 psi (55 - 83 KPa).
Why is my BigDog Alpha MP Lawn Mower vibrating abnormally?
Abnormal vibration can occur if the engine mounting bolts are loose. Make sure that you tighten the engine mounting bolts.

Tighten any loose blade mounting bolts and replace or tighten a worn or loose spindle bearing.
