04781700 Starter Solenoid Starter Relay Solenoid Replacement for Ariens Gravely Zoom Ikon ZTX ZT XL Zero Turn Mowers

What It Is

The 04781700 starter solenoid is an electromagnetic relay that engages the starter motor when you turn the key. It’s designed for Ariens and Gravely zero-turn mowers, specifically models like the Zoom, Ikon, ZTX, ZT, and XL series.

Fitment & Compatibility

Before buying, verify these three things:

• OEM Part Number: This replaces Ariens/Gravely OEM #04781700. Cross-check your mower’s manual or existing solenoid for that exact number.
• Terminal Layout: It has three terminals: two large (battery and starter) and one small (trigger wire). Measure the mounting hole spacing—typically 2.5 inches center-to-center. If yours is different, it won’t bolt up.
• Voltage: Works on 12V systems only. Not for 6V or older models.
• Deck size/engine doesn’t matter—fitment is based on the electrical system and bracket holes, not cutting width or horsepower.

Key Things to Know

• Quality: This is an aftermarket part at a low price. It may not last as long as OEM, but for $10.99 it’s a reasonable quick fix.
• Installation: Easy—disconnect battery, remove two mounting bolts and three wires, reverse steps. No special tools needed.
• Common gotcha: A clicking sound but no start often means a weak battery or bad ground, not a bad solenoid. Test voltage at the solenoid first.
• Warranty: Check seller policy; many budget solenoids have limited or no returns after installation.

Should You Buy It

If you need a cheap, quick replacement for a dead solenoid on a Gravely or Ariens zero-turn and you’re comfortable with basic wiring, this will get you running. But if you want OEM durability or your mower is under warranty, spend more on the factory part.
