Starter Motor for Kohler KT17-KT19, Magnum M18-M20 & MV16-MV18 Engines
Kohler KT, Magnum M and MV series engines, Cub Cadet garden tractors 1985-1993 - 12V, CCW
A starter motor is the component that cranks the engine over to begin combustion. If it fails to engage, spins without turning the engine, or does not respond at all when the key is turned or the start button is pressed, the engine will not start. This starter motor is built for Kohler KT series (KT17, KT19), Magnum (M18-M20) and MV (MV16S, MV17, MV18) engine applications, engineered as a direct replacement that matches the original unit's fit, mounting and function.
It is a 12V permanent magnet direct drive (PMDD) unit with counter-clockwise (CCW) rotation and a 9-tooth drive pinion, with a motor housing length of 4.033in matching the original Kohler specification. It is the starter used across the Cub Cadet 18HP Kohler-engined garden tractor range built between 1985 and 1993.
