Small single-cylinder tractors use a smaller starter than the V-twin machines, and the difference that bites is the tooth count. The T210 takes a nine-tooth pinion, and a ten-tooth motor will not mesh.
Craftsman builds the T210 around a 42-inch deck and a Kohler 5400 Series single-cylinder engine, air-cooled, in the 18 hp class, with a Tuff Torq K46 hydrostatic transmission. The starter is a 0.7 kW nine-tooth counter-clockwise unit.
The motor is a permanent-magnet direct drive with copper stator and rotor windings and a plated steel barrel. There is no reduction gearset, so the body is short and there is no gear train inside to fail.
The flange is a two-bolt pattern with 8 mm holes and a pilot spigot that centres the motor. The original bolts and the heat shield go back on unchanged.
Because the engine is a single, cranking compression comes in one hard pulse per revolution rather than two. That is why the tooth count and the pinion engagement matter more here than on a twin. Check that the pinion throws freely before you bolt the motor down.
Test the battery and the solenoid first. On these tractors a flat battery and a sticky relay account for most no-crank complaints, and neither is fixed by a new motor.
Clean the terminals and the frame ground, then crank in bursts of ten to fifteen seconds. The motor is intermittent duty.
Craftsman has sold the T210 since 2019. The deck and the engine stayed consistent across that run, but the model number on the fender is the thing to check, since Craftsman also sells the T210 under several retailer-specific codes.
No torque, current draw or no-load speed is published for this unit. We list voltage, power, teeth, rotation and flange, which is what the fit actually depends on.
Supplied bare. Reuse the solenoid, the bolts and the heat shield, and inspect the ring gear teeth while the motor is off the engine.
Stock ships in 15 to 30 days, minimum one piece, twelve-month replacement warranty on the windings and the bearing.
