Grasshopper Mower Push/Pull PTO Switch, Engages PTO Shaft Clutch and Clutch Assembly on Grasshopper FrontMount Mowers, Genuine Replacement Part, OEM 183925

What It Is

This is a genuine Grasshopper OEM push/pull PTO switch (part number 183925) that engages the PTO shaft clutch and clutch assembly on Grasshopper FrontMount mowers. It’s a direct replacement part for the switch that controls electric PTO engagement, not the clutch unit itself.

Fitment & Compatibility

Before buying, confirm your mower model and year. This switch fits most Grasshopper FrontMount mowers with electric PTO clutches (e.g., 721D, 725D, 928D, 932D, 325D, 327D, and similar models from the 1990s–2010s). Check your existing switch: it should be a push/pull type (not toggle or rocker). Measure the mounting hole diameter (typically 1/2 inch). Verify that your mower uses a two-wire or three-wire PTO clutch system—this switch is designed for two-wire setups. If you have an older model with a mechanical PTO, it will not work. Always cross-reference your mower’s serial number with Grasshopper’s parts diagram to avoid mismatch.

Key Things to Know

• Quality: Genuine Grasshopper OEM part, not aftermarket. Durable plastic housing and metal terminals; should last several seasons under normal use.
• Installation difficulty: Easy (1/10). Unplug the old switch, remove the mounting nut, install the new switch, and reconnect. No special tools needed.
• Common gotcha: The switch may feel slightly stiffer than the original at first—this is normal and loosens with use. Ensure the wiring harness connector is fully seated; a loose connection can cause intermittent PTO engagement.
• Check the clutch first: If the PTO fails to engage, test the clutch itself (resistance and ground) before replacing the switch. A bad clutch will not be fixed by a new switch.

Should You Buy It

If your Grasshopper FrontMount mower’s PTO doesn’t engage or disengage properly and you’ve confirmed the clutch is good, this OEM switch is a reliable, low-cost fix. It’s ideal for DIY owners who want a direct-fit replacement without wiring headaches. Skip it if you need a different switch type or if the clutch itself is faulty.
