MTD Yard Machines LT4200 547cc Lawn Tractor Starter Motor | 12V 0.6kW 9T CW | OE 725-06300

Read the rotation before you order anything for an LT4200. This motor turns clockwise as you look at the drive end, and most of the starters in this size class turn the other way. Fitting the wrong one will not crank the engine at all.

MTD builds the Yard Machines LT4200 around a 42-inch deck, a single-cylinder air-cooled engine and a seven-speed transmission. It is a light tractor and it takes a light starter: 0.6 kW, nine teeth, clockwise.

Inside is a permanent-magnet direct drive with copper stator and rotor windings and a plated steel barrel. No reduction gearset, so there is no gear train to strip.

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

The nine-tooth pinion and the clockwise rotation are the two things to verify against the motor you are removing. Count the teeth, and note which way the pinion faces when the motor is mounted.

Check the battery and the solenoid before ordering. On MTD-built tractors a sticky relay is a common cause of a single click and no crank, and a new motor will not fix it.

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

MTD has sold the LT4200 under several model numbers over the years, and the engine supplier changed across that run. The starter pattern did not change on the 42-inch tractors, but check the motor you are taking off before ordering.

No torque, current draw or no-load speed is published for this unit. We state voltage, power, teeth, rotation and flange and leave the rest blank.

Supplied as the motor alone. Reuse your solenoid, your bolts and your heat shield, and inspect the ring gear while the motor is off.

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