For uneven cutting, check if the mower deck is level and ensure the blades are sharp. Replace or sharpen blades as necessary, and ensure tires are inflated to the correct pressure.
Before storing, clean the tractor, change the oil, remove the battery and store it in a cool dry place, and add a fuel stabilizer to the gas tank. Cover the tractor to protect it from dust and moisture.
To replace the blades, remove the mower deck, use a block to secure the blade, and loosen the blade bolt with a wrench. Replace the blade and tighten the bolt securely. Reattach the mower deck.
Excessive vibration can be caused by unbalanced or damaged blades, loose parts, or worn engine mounts. Inspect and balance blades, tighten loose components, and replace any damaged parts.
