725-06153A Starter Solenoid Relay for Riding Lawn Mower, 12V Relay Switch, Fit for Cub Cadet/Enduro/RZT/MTD/Troy Bilt/Yard Man/Husky/Yard Machines/Craftsman Zero Turn, Replace 725-06153

What It Is

This is a 12V starter solenoid relay that controls high-current flow from the battery to the starter motor when you turn the ignition key. It’s designed for riding lawn mowers and zero-turn mowers—specifically Cub Cadet, MTD, Troy-Bilt, and Craftsman models that use the OEM part 725-06153.

Fitment & Compatibility

• Direct replacement for OEM part 725-06153 (also supersedes 725-06153A).
• Fits models from: Cub Cadet (Enduro, RZT series), MTD, Troy-Bilt, Yard Man, Huskee, Yard Machines, Craftsman zero-turn mowers.
• Check your mower’s model number (not just brand) – look under the seat or on the frame. This relay is not universal; it only fits units originally equipped with the 725-06153.
• Measurements: Two large terminal studs (3/8”–16 thread) for battery/starter cables, two small spade terminals for ignition switch wires. Body is roughly 1.5” x 1.5” x 2”.
• Voltage: 12V only. Do not use on 6V or 24V systems.
• Aftermarket vs OEM: This is an aftermarket replacement; build quality is similar to OEM, but not identical—some users report slightly different terminal orientation. Verify your existing solenoid’s terminal positions before buying.

Key Things to Know

• Installation is simple – disconnect battery, remove two small wires and two large cables, swap relay, reconnect. No special tools needed.
• Common gotcha: The small wires (ignition signal) are often spade connectors that may be loose on aftermarket terminals. Gently squeeze the female spades with pliers for a snug fit.
• Quality note: 4.2 stars from 45 reviews is solid for a $14 part. Most complaints are about fitment (terminal angle) or intermittent operation after a few months—not a dealbreaker for occasional use.
• Test before full reassembly: Turn key to “start” – you should hear a clear click. If not, check battery voltage and ground connections first.

Should You Buy It

If your mower uses the 725-06153 and you’re comfortable with basic wiring (two large cables, two small wires), this is a cheap, effective fix for a no-crank or intermittent starting issue. It’s not built for heavy commercial use, but for homeowner mowing it’s a solid value. Skip it if you need OEM-grade durability or if your mower’s solenoid has unusual terminal angles.
