HD Switch Starter Ignition Key Switch fits John Deere 130 160 165 170 175 180 185 240 245 260 265 285 320 500 Garden Tractor Mowers w/Protective Umbrella Key, 3 Keys & Free Carabiner

What It Is

This is a replacement starter ignition key switch for select John Deere garden tractors and lawn mowers. It includes a protective umbrella key, three spare keys, and a carabiner for easy carrying.

Fitment & Compatibility

Before purchasing, confirm your John Deere model matches this list: 130, 160, 165, 170, 175, 180, 185, 240, 245, 260, 265, 285, 320, and 500. This switch is an aftermarket replacement for OEM part numbers AM104078, AM102667, AM104078, and MIA11748. Measure your existing switch’s terminal count (typically 3 or 5 prongs) and ensure it aligns. Deck size doesn’t matter—fitment is by tractor model only. Check your mower’s serial number if you’re unsure; some older units may have different wiring.

Key Things to Know

• Quality & durability: Users report solid construction, with the protective umbrella key preventing debris from jamming the switch. The included carabiner is a nice bonus for key storage.
• Installation: Simple swap—disconnect the battery, remove the old switch, plug in the new one, and secure it. No special tools needed. Wiring colors may vary slightly from OEM; take a photo before removing the old switch.
• Common gotcha: If your mower has a safety interlock (e.g., blade engagement, seat switch), ensure the new switch matches your wiring configuration. Some models use a 5-terminal switch; this one is 3-terminal. Verify before buying.
• Key compatibility: The three spare keys are duplicates of the main switch key, not universal. Keep one in a safe place.

Should You Buy It

This is a solid, budget-friendly replacement for common John Deere garden tractors. It’s ideal if your original switch has failed (won’t turn, intermittent starting) or you want a spare set of keys. Skip it if your mower isn’t on the model list or requires a different terminal count.
