Cub Cadet Unequal Wheel Speed / Alignment Issue

Robot mower veers to one side and does not drive straight

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Unequal tire wear, Debris in one wheel, Faulty wheel encoder on one side, Calibration drift in drive control

Safety first: Turn OFF the mower and disconnect the battery before wheel inspection.

Swap wheels (test): Swap left and right drive wheels if possible. If the veering direction changes, the wheel itself is the issue.
Clean wheel hubs: Remove debris from the affected wheel hub and axle.
Check encoder area: Inspect the encoder disc and sensor on the side that seems slower or faster.
Service calibration: Some Cub Cadet models allow wheel calibration via service menu; follow service documentation.
