  If your McCulloch Riding mower will not start, several factors could be at play. It might be out of fuel, so start by filling the fuel tank. A bad spark plug could also be the culprit, requiring a replacement. Other potential causes include a dirty air filter (clean or replace it), water in the fuel (empty and refill with fresh gasoline, replacing the fuel filter), or loose/damaged wiring (check all wiring). In some cases, the engine valves may be out of adjustment, which requires contacting a qualified service center.

Why does my McCulloch M95-66XC have poor grass discharge?
- J
  John WallaceAug 30, 2025
  If your McCulloch Riding mower has poor grass discharge, several factors could be responsible. Ensure you're not traveling too fast by shifting to a slower speed. Wet grass can also cause this issue, so allow the grass to dry before mowing. Check that the mower deck is level and the tire air pressure is correct. A worn, bent, or loose blade can also contribute, so replace or sharpen the blade. Additionally, a buildup of grass, leaves, and trash under the mower can be the cause. A worn mower drive belt or an improperly installed blade can also lead to poor discharge. Finally, clogged mower deck vent holes from buildup of grass, leaves, and trash around mandrels. Replace with blade listed in this manual or clean around mandrels to open vent holes.
