Solenoids

Switches and solenoids for ride on mowers, from ignition switches and keys through to PTO switches and starter solenoids. These are the parts that control starting the engine, engaging the blades, and sending power to the starter motor, so a fault here usually shows up as a mower that won't start or a deck that won't engage.

Match the part to your mower by brand and model, as ignition switches, PTO switches and solenoids are wired and shaped differently across makes like John Deere, Husqvarna, Toro, Cub Cadet and MTD. Solenoids are also sold by terminal count (commonly 2 or 4 terminal) and voltage, so check the old part or your mower's wiring before buying.

Frequently asked questions

How do I know if it's the ignition switch or the solenoid that's faulty?

If the mower does nothing at all when you turn the key, the solenoid is often the culprit since it's what sends power to the starter motor. If the key turns but nothing happens electrically, or accessories won't switch on, the ignition switch itself may be worn out.

What does a PTO switch do?

The PTO switch engages and disengages the mower blades (the power take-off). If the blades won't engage or the mower won't start with the blades engaged as a safety check, the PTO switch is a common cause.

How many terminals does my solenoid need?

Ride on mower solenoids are commonly either 2 pole or 4 terminal, and the wrong type won't wire up correctly. Check the terminal count and voltage on your existing solenoid before ordering a replacement.

Will any ignition switch fit my mower?

No, ignition switches vary by brand and model, so you'll need to match the switch to your mower's make, model and sometimes the specific part number to get a proper fit.
