What It Is

This is a 5-terminal, 3-position ignition switch (Off/Run/Start) designed to replace failed keyswitches on riding lawn mowers and zero-turn tractors. It’s a direct aftermarket replacement for Cub Cadet, MTD, Craftsman, Troy-Bilt, Ariens, Bad Boy, and some John Deere models.

Fitment & Compatibility

Before buying, verify these three things:

• Terminal count & position: Must be 5 terminals (usually labeled B, S, A1, A2, G or similar). Count your old switch’s terminals and note their layout.
• OEM part numbers: Cross-reference your current switch with #925-04659, 725-04659, or 725-04228. If your mower uses one of these, this switch will work.
• Physical size & key shape: Shaft diameter is typically 3/8” and overall length ~2.5”. Measure your old switch’s mounting hole and depth to ensure it fits the dash. Key shape may differ slightly from OEM—test fit before reassembling.

Does not fit all John Deere (only specific models using the listed OEM numbers). Not for push mowers or zero-turns with non-standard terminal layouts.

Key Things to Know

• Quality is adequate for the price: Plastic housing feels less robust than OEM, but electrical contacts are reliable. Expect 2–3 seasons of normal use.
• Installation is straightforward: Disconnect battery, unplug harness, remove old switch (usually a nut or clip), install new one, reconnect wires by matching terminal labels. No special tools needed.
• Common gotcha: Wire colors may not match your mower. Use terminal labels (B = battery, S = starter, etc.) instead of colors. Take a photo before disconnecting.
• Key is included but generic: The key works the switch but may not match your mower’s existing key or lock cylinder. Keep the new key in a safe spot.

Should You Buy It

If your mower uses one of the listed OEM part numbers and you want a cheap, functional replacement without paying $25+ for a brand-name switch, this is a solid choice. It’s not as durable as OEM, but for occasional home use it’ll get the job done. Avoid if you need exact key duplication or a heavy-duty commercial-grade switch.
