Product Overview

The TimeCutter SS5000 is a 50-inch zero-turn with Toro's own 708 cc V-twin, and it starts and stops constantly around landscaping. That is the duty that wears a starter out. This is the replacement.

The engine is a 24.5 hp Toro V-twin, air-cooled, feeding a three-blade stamped deck through dual Hydro-Gear EZT transmissions. Its starter is a 10-tooth counter-clockwise motor, which is what this listing covers.

Inside is a permanent-magnet direct-drive layout. Copper stator, copper rotor, plated steel barrel, sealed bearing at the drive end. No reduction gear, no field coil, nothing to strip when the engine kicks back.

Mounting is the standard two-bolt flange with 8 mm holes and a pilot spigot. It lands on the engine boss with the original bolts and no shimming.

Diagnose before you buy. One click and no crank is usually the solenoid. A motor that groans and heats up, or that turns the engine a half turn and stops, is the motor. A motor that will not turn at all with a fresh battery is either the motor or the ground strap.

Clean the battery terminals, the ground at the frame and the studs on the solenoid before the new motor goes on. Toro's zero-turns sit the engine on rubber mounts, so the ground strap carries everything.

Crank in short bursts of ten to fifteen seconds. The motor is intermittent duty and does not want to be held against a flywheel that is not turning.

Toro has built the SS5000 across a run of model years under the 74731 model number. The engine and the deck stayed the same; if your machine carries a different model number, check the motor before ordering.

We do not publish torque, current draw or no-load speed for this unit because we have no test sheet for it. The stated figures are voltage, power class, tooth count, rotation and flange pattern.

Supplied as the motor alone. Keep your solenoid, your relay and your heat shield. Check the ring gear for burrs while the motor is off; a worn ring gear will chew a new pinion.

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