1-633651 Battery Hold Down Bolt, for Toro Exmark Lazer Z, Vantage, Turf Tracer, Navigator, Quest Zero Turn Lawn Mower Battery

What It Is

The Toro 1-633651 Battery Hold Down Bolt is a replacement fastener designed to secure the battery in place on select Exmark zero-turn mowers. It prevents battery movement during operation, reducing vibration damage and electrical disconnections.

Fitment & Compatibility

Before buying, verify your mower model. This bolt fits:

• Exmark Lazer Z (all series), Vantage, Turf Tracer, Navigator, and Quest zero-turn models
• OEM part number 1-633651 (genuine Toro, not aftermarket)
• Measures approximately 5/16" diameter and 3.5" long with a threaded end and a J-hook or L-bracket design

Check your existing bolt: if it’s missing or broken, this is a direct replacement. If your mower uses a different battery hold-down system (e.g., strap or wedge), this won’t work. Measure the battery tray hole spacing and bolt length to confirm compatibility.

Key Things to Know

• Quality: Genuine Toro part, plated steel resists rust; not a cheap stamped alternative.
• Installation: Simple—remove old bolt, slide new one into battery tray slot, tighten nut. No special tools required.
• Common gotcha: Some models use a different thread pitch (fine vs. coarse). This bolt uses standard 5/16-18 threads; if your nut doesn’t fit, you may need a new nut (not included).
• Price vs. aftermarket: $9.99 is fair for OEM; generic bolts cost $3-5 but may bend or corrode faster.

Should You Buy It

Buy this if you need a direct OEM replacement for a broken or missing battery hold-down bolt on an Exmark zero-turn mower. It’s exactly what you need—no guesswork, no modding. Skip it if your mower uses a different hold-down system (e.g., strap or plastic clamp) or if you’re fine with a generic bolt that might not fit perfectly.
