Could a failing Rear Drive Motor Assembly cause the EGO LM2135SP POWER+ SELECT CUT to have symptom: Power Plus Lm2135Sp Mower Self Propelled Motor Fail?

The self-propel motor in this model is a brushless DC unit integrated with a sealed reduction gearbox. Mechanical failure occurs when the internal nylon gears strip or the 'anti-rollback' clutch pins jam, preventing the motor from translating torque to the drive shaft. Because these internal components are not sold individually and the motor casing is often ultrasonically welded or sealed, the entire drive unit must be replaced to restore propulsion.

Could a failing Drive Gear Kit (Left and Right Pinions) cause the EGO LM2135SP POWER+ SELECT CUT to have symptom: Power Plus Lm2135Sp Mower Self Propelled Motor Fail?

These nylon pinion gears transfer power from the drive shaft to the rear wheels. They are designed as a mechanical 'fuse' to protect the motor, often stripping their internal splines if the mower is forced against an obstruction or heavily overloaded. If the SP motor is audible but the mower does not move, these sacrificial components have likely failed.

Could a failing Self-Propel Control Cable cause the EGO LM2135SP POWER+ SELECT CUT to have symptom: Power Plus Lm2135Sp Mower Self Propelled Motor Fail?

Physical fatigue or stretching of the actuation cable can prevent the internal motor switch or mechanical engagement lever from reaching its 'closed' position. This results in an intermittent or total lack of signal to the motor controller, which is frequently misdiagnosed as a dead motor.
