Nylon Turntable Disc with M4 Thread Replacement wheel plate for robotic lawnmower and grass mower applications Key benefits Restores wheel function quickly: replaces worn or damaged wheel plates to recover smooth rolling and steering. Durable and low maintenance: molded nylon construction resists wear, keeps performance over repeated use. Easy to install: M4 threaded connection aligns with common wheel assemblies for straightforward replacement. Reduces vibration and noise: precise fit and smooth bearing surface improve ride stability and cutting consistency. What this part does This turntable disc serves as the wheel plate in robotic lawnmowers and compatible grass mowers. It provides the rotating interface between the wheel and the mower chassis, transferring load while allowing rotation. The integrated M4 thread enables secure attachment to existing wheel hardware. Important attributes Material: strength nylon for impact resistance and long service life. Thread: standard M4 threaded mounting for compatibility with many lawnmower wheel assemblies. Function: replacement wheel plate and turntable disc to restore rotation and alignment. Performance: engineered for low friction rotation and consistent contact under typical lawnmower loads. Compatibility Designed to fit robotic lawnmowers and grass mowers that accept an M4 threaded wheel plate. Suitable as a direct replacement where the original part uses a nylon turntable disc with M4 mounting. Basic installation guidance Remove the damaged plate and clean mating surfaces. Align the disc, engage the M4 thread, and tighten securely without overtightening. Verify rotation and correct wheel alignment before operation. Practical use scenarios a cracked or worn wheel plate after extended seasonal use to restore stable mowing and navigation. Perform onsite when a wheel assembly seizes or becomes noisy during operation. Keep a spare on hand for routine maintenance to minimize downtime during the mowing season. Why this part matters A properly functioning turntable disc maintains wheel alignment and rotation, which supports accurate path navigation and even cutting. The nylon construction and M4 threaded interface make this a reliable replacement part for many robotic mower maintenance needs.
