What It Is

This is a 3-post starter solenoid that acts as a high-current relay between your lawn mower battery and starter motor. It’s designed for MTD, Toro, Snapper, and other riding mowers or garden tractors that use a standard 12V starting system.

Fitment & Compatibility

Before buying, confirm your mower uses a 3-terminal solenoid with two large posts (battery/starter) and one small trigger terminal. This BlueStars unit cross-references OEM numbers: MTD 925-1426, 925-1426A, 725-1426A, 725-0771, 925-0771; Snapper 18817, 75671; Toro 112-0309, 334009B, 435-065. It fits most MTD, Troy-Bilt, Cub Cadet, Craftsman, Husqvarna, and John Deere models using these part numbers. Measure your mounting hole spacing (typically 2.5” or 3” center-to-center) and check terminal orientation (posts should face away from engine or frame). If your old solenoid has 4 terminals, this 3-post version won’t work without rewiring.

Key Things to Buy

• Quality is acceptable for the price—users report consistent performance, but a small number fail within a season. It’s a standard Chinese-made aftermarket part, not OEM.
• Installation is straightforward (10-15 minutes): disconnect battery negative, remove two mounting bolts, swap wires one at a time. No special tools needed.
• Common gotcha: the mounting bracket may require slight bending to align with existing holes on some mowers. Also, the small trigger terminal nut is 5/16”, so have a wrench ready.
• Check your old solenoid for corrosion or melted plastic—if the engine cranks slowly or clicks, this is often the fix. No need to replace if the mower starts fine.

Should You Buy It

If your mower’s starter solenoid is dead (clicking, no crank) and you need a cheap, drop-in replacement that matches the listed OEM numbers, this is a solid budget choice. It’s not built for heavy commercial use, but for a residential rider or garden tractor, it’ll get you running again without breaking the bank.
