117-1197 Starter Solenoid 4 Terminal for EXMARK Lawn Boy 117-1197 1-513075 513075 104-3189 212655 for Toro Lawn Tractor 104-3189,12V Lawn Mower Starter Solenoid

What It Is

This 4-terminal 12V starter solenoid (OEM cross 117-1197, 1-513075, 104-3189) engages the starter motor when you turn the key on Exmark, Toro, and Lawn Boy zero-turn mowers and tractors. It’s a direct replacement for the original part, not a universal adapter.

Fitment & Compatibility

Before buying, check your mower’s model number (not just brand). This solenoid fits Exmark LZ, Lazer Z, and Turf Tracer series; Toro TimeCutter, Titan, and Z Master zero-turns; and Lawn Boy Insight mowers. Also compatible with Toro lawn tractors using part 104-3189. Verify your existing solenoid has four terminals (two small spades, two large posts) and measure mounting hole spacing: center-to-center is 2.25 inches. If your unit uses a different pattern or has three terminals, this won’t work. Cross-reference your OEM part number against 117-1197, 1-513075, 513075, 104-3189, or 212655.

Key Things to Know

• Quality: This is an aftermarket part, but at $8.99 it’s a fraction of OEM cost. Most users report it works well, though some note slightly thinner gauge wire on the coil terminals—still functional for residential use.
• Installation: Simple swap—disconnect battery, remove two small control wires and two large battery/starter cables, then mount with two bolts. No special tools needed. Takes 10–15 minutes.
• Common gotcha: The mounting bracket is fixed orientation. If your original bracket was angled or offset, this flat bracket may require minor bending or shimming to align bolt holes. Check clearance before tightening.
• Voltage: 12V only—do not use on 6V systems or with incorrect battery polarity.

Should You Buy It

Buy this if you need a budget-friendly, drop-in replacement for a failed solenoid on a common Exmark, Toro, or Lawn Boy mower and you’re comfortable with a basic electrical swap. Skip it if you need a heavy-duty commercial unit for daily use in harsh conditions—OEM or a premium aftermarket brand may last longer. For homeowners and light commercial users, this is a solid value at under $10.
