  If your Excel Lawn Mower blades do not rotate, it could be due to several reasons. The deck drive belt might be worn, loose, or broken, requiring you to install a new one. Alternatively, the belt might be off the pulley, so reinstall it and check for the reason.

  If your Excel Lawn Mower is producing an uneven cut, it could be due to several factors. The blades might not be sharp, so sharpen them. A cutting blade might be bent, so install new cutting blades. Check if the deck is level. Ensure that the anti-scalp wheels are set correctly and adjust their height if needed. Clean the underside of the deck if it's dirty. Finally, verify that the tires are properly inflated, adjusting the air pressure to 8 - 12 psi (55 - 83 KPa).
