Troubleshooting: Blade Disc Motor Overcurrent

If your mower reports a blade disc motor overcurrent error or the blade disc stops rotating unexpectedly, please follow the steps below to identify the possible cause.

1. Check the Lawn Terrain

Inspect the mowing area for uneven ground, soil mounds, bumps, rocks, or other obstacles. Challenging terrain may increase the load on the blade disc motor and trigger the overcurrent protection.

2. Check the Blades

A. Inspect Blade Condition

Check whether the blades are excessively worn, chipped, bent, or damaged. Damaged blades can increase cutting resistance and place additional load on the blade disc motor.

B. Verify Blade Movement

Ensure that each blade can rotate freely on the blade disc. Grass clippings, dirt, or other debris may prevent the blades from moving properly, resulting in increased motor load and potential overcurrent faults.

3. Check the Blade Disc Assembly

Manually rotate the blade disc and verify that it spins smoothly without any resistance, rubbing, or sticking.

If the blade disc does not rotate smoothly, please refer to the blade disc replacement video and remove the blade disc for further inspection. Pay particular attention to the following:

• Check for grass, string, branches, or other foreign objects that may be obstructing the blade disc.
• Inspect the blade disc and the blade disc guard for signs of contact or friction.
• Verify that the blade disc assembly is not deformed, damaged, or improperly installed.

Any of the above conditions may increase the resistance on the blade disc motor and trigger the overcurrent protection.

Safety Notice

Before inspecting or disassembling the blade disc, power off the mower and wear appropriate protective equipment, such as cut-resistant gloves, to avoid injury.
