Deck Noise
H3: Worn Bearings
The deck of your riding mower houses the blades and can contribute to noise if its bearings are worn.
- Worn bearings: Worn bearings in the deck spindle can create a grinding or rattling sound.
H4: How to Check for Deck Bearing Issues:
Check for excessive play or looseness in the deck spindle. If you feel any unusual movement or hear grinding sounds, the bearings might need replacing.
Wheel Noise
H3: Worn Wheels and Bearings
Worn or damaged wheels and bearings can cause a variety of noises.
- Worn tires: Worn tires can create a squeaking or rubbing noise, especially when turning.
- Worn wheel bearings: Worn wheel bearings can cause a grinding or rumbling noise, particularly when turning or going over uneven terrain.
H4: How to Check for Wheel and Bearing Issues:
Inspect the tires for wear and tear and check for any play or looseness in the wheel hubs. If you detect any unusual noise or movement, the bearings might need to be replaced.
