725-06153A 725-06153 Starter Solenoid Relay for Riding Lawn Mower Compatible with Cub Cadet XT1 XT2 Enduro RZT LT1 ZT1 ZT2 MTD Troy Bilt Yard Man Husky Yard Machines Craftsman Zero Turn

What It Is

This is a starter solenoid relay that acts as an electrical switch, sending battery power to the starter motor when you turn the key. Designed for riding mowers and zero-turn models from Cub Cadet, MTD, Troy-Bilt, Yard Man, Husky, Yard Machines, and Craftsman.

Fitment & Compatibility

• Check your OEM part number: Confirm your original solenoid is 725-06153 or 725-06153A. This is a direct replacement for those numbers.
• Verify machine series: Compatible with Cub Cadet XT1, XT2, Enduro, RZT, LT1, ZT1, ZT2 and equivalent MTD-built models from Troy-Bilt, Husqvarna, Yard Man, Yard Machines, and Craftsman.
• Physical dimensions: About 2.3” x 1.8” x 1.8” with two large terminal studs (battery/starter) and two small spade terminals (ignition/ground). Measure your old unit to be sure.
• Voltage rating: 12V DC only—do not use on 6V or 24V systems.
• Mounting: Two bolt holes on 2” center spacing. Check your bracket holes match before ordering.

Key Things to Know

• Quality: Aftermarket unit, not OEM Cub Cadet. Most users report it works fine, but a small number note faster wear than OEM. For the price, it’s a reasonable trade-off.
• Installation difficulty: Easy, 15-minute job. Disconnect battery first, swap two large and two small wires, reattach. No special tools needed.
• Common gotcha: The small terminal marked “S” or “I” must connect to the ignition wire—wrong hookup causes no-start or dead battery. Snap a photo of your old wiring before removing.
• Failure symptoms: Clicking but no crank, intermittent starting, or completely dead starter response. Test with a multimeter before buying to rule out a bad battery or starter motor.

Should You Buy It

If you need a budget-friendly replacement for a failed solenoid on a Cub Cadet or MTD-built rider, and you’re comfortable with basic wiring, this is a solid pick. Skip it if you want OEM reliability for a commercial-use mower—spend more on a genuine Cub Cadet part instead.
