Possible Causes

How to Fix / Troubleshooting
Safety: Turn OFF the mower and wear gloves when working near the cutting deck.
- Check for debris: Inspect the area around the cutting height mechanism for stones, sticks, or packed grass preventing movement.
- Manual movement: If the model allows, gently move the deck up and down by hand to free a stuck mechanism.
- Listen for motor: While adjusting height from the menu (with blades disabled), listen for the actuator motor. No sound suggests a failed motor or wiring issue.
- Inspect wiring: Access the height actuator and verify the connector is secure and wires are not damaged.
- Replace actuator: If the mechanism remains stuck or the motor is silent, replace the TerraMow cutting height actuator assembly.
