Troy-Bilt Pony 42 547cc Riding Lawn Mower Starter Motor | 12V 0.7kW 9T CCW | OE 925-06300

The Pony 42 is the tractor a lot of people start with, and its starter is the part that ends a mowing season early. Nine teeth, counter-clockwise, 0.7 kW. Get one of those three wrong and it will not work.

Troy-Bilt fits a 547 cc single-cylinder engine, air-cooled, with a seven-speed Shift-On-The-Go transmission and a 42-inch twin-blade deck. The starter is a 0.7 kW nine-tooth counter-clockwise unit.

Inside is a permanent-magnet direct drive with copper stator and rotor windings and a plated steel barrel. No reduction gearset, so nothing inside to strip when a single-cylinder kicks back against compression.

Two-bolt flange, 8 mm holes, pilot spigot. The original bolts and heat shield transfer over, and the spigot sets the pinion depth.

Single-cylinder engines are harder on a starter than twins: one compression stroke per revolution instead of two, and the engine rocks on its mounts when it fires. That is why the pinion and the drive end bearing take the wear first.

Check the battery and the solenoid before ordering. A Pony that clicks once and does nothing is usually the relay. A Pony that cranks slowly and smells hot is the motor.

Clean the terminals and the frame ground, then crank in bursts of ten to fifteen seconds. The motor is intermittent duty.

Troy-Bilt has built the Pony 42 for years with more than one engine supplier. The 547 cc version is the one this motor is listed against; if your tractor carries a smaller Briggs engine, check the motor before ordering.

No torque, current draw or no-load speed is published here. We state voltage, power, teeth, rotation and flange, and leave the rest blank rather than fill it with a guess.

Supplied bare. Reuse your solenoid, your bolts and your heat shield, and look at the ring gear teeth while the motor is off.

Ships from stock in 15 to 30 days. Minimum one piece. Twelve-month replacement warranty against winding and bearing failure.
