Could a failing Self-Propel Drive Motor Assembly cause the EGO LM2135SP to have symptom: Power Lm2135Sp Mower Self Propelled Failure?

This is the core electromechanical unit containing the motor and gearbox. Internal failure of the worm gear or planetary set results in a total loss of drive torque. Because the gearbox is a sealed unit, the entire assembly must be replaced to restore the self-propulsion function.

Could a failing Drive Pinion Gear Kit cause the EGO LM2135SP to have symptom: Power Lm2135Sp Mower Self Propelled Failure?

These nylon gears sit at the ends of the drive shaft and transfer power to the wheels. They act as a mechanical fuse; over time, the teeth shear or the internal pawl/clutch mechanism jams, causing the wheels to either slip under load or lock up when the mower is pulled backward.

Could a failing Rear Drive Wheel cause the EGO LM2135SP to have symptom: Power Lm2135Sp Mower Self Propelled Failure?

The internal circumference of the rear wheel features a molded plastic ring gear. When the drive pinions experience heavy loading, they often strip the teeth on the wheel itself. Replacing the wheel is necessary if the internal gear teeth are rounded, preventing the pinion from finding purchase.
