Belt Replacement
Replacing a worn or damaged drive belt restores power transfer to the wheels. Begin by disconnecting the spark plug for safety. Carefully remove the mower deck, noting the belt’s routing.
Release tension on the belt tensioner to remove the old belt. Install the new belt, ensuring it’s correctly seated in all pulleys. Re-engage the tensioner and verify the belt runs smoothly. Reattach the deck and reconnect the spark plug. If unsure, consult your Mountfield dealer at 0800 121 6585 for guidance.
Clutch Adjustment and Repair
A properly adjusted clutch ensures smooth engagement and disengagement of the drive system. Begin by ensuring the engine is off and the spark plug is disconnected. Check the clutch cable for wear or damage, replacing if necessary.
Adjust the clutch cable tension using the adjuster near the handle. The clutch should engage smoothly when the lever is fully engaged. If the clutch slips, further adjustment may be needed, or internal clutch components may require repair. For complex issues, contact an authorized Mountfield dealer at 0800 121 6585.
Electrical System Troubleshooting
Diagnosing electrical issues starts with the battery. Ensure it’s fully charged and connections are clean. Check the battery terminals for corrosion and clean them with a wire brush. Inspect the ignition system, including the ignition coil and spark plug wire, for damage.
