Jungle Jim's Large Mower Holder, Caster Wheel Lockdown for Zero Turn Mowers (ZTR), Fits 10.5"–12.5" Caster Tires, Secure Transport for Lawn and Landscape Trailers, Removable and Lockable Design

What It Is

This is a removable caster wheel lockdown system for zero-turn mowers (ZTRs), designed to secure the front caster wheels during trailer transport. It fits tires with a diameter of 10.5" to 12.5" and prevents the mower from shifting or turning while on a trailer.

Fitment & Compatibility

• Tire size only: Check your front caster tire diameter (not wheel rim). Measure from the ground to the top of the tire tread. Must be between 10.5" and 12.5".
• No mower brand restriction: Works with any ZTR from John Deere, Toro, Kubota, Gravely, Scag, Husqvarna, Bad Boy, etc., as long as tire size matches.
• Trailer deck type: Designed for flatbed lawn/landscape trailers. Not for tilt-bed or ramps with built-in wheel chocks.
• OEM vs aftermarket: Works equally with stock or aftermarket caster tires of the correct diameter. No modification needed.
• Measurement tip: Inflate tires to normal operating pressure before measuring. Over- or under-inflated tires will throw off fit.

Key Things to Know

• Installation: No drilling or permanent modification. Slides over the caster tire and locks with a pin. Takes under 2 minutes per wheel once you get the hang of it.
• Locking mechanism: Uses a removable padlock (not included) to deter theft. The pin itself is heavy-duty steel with a zinc coating.
• Weight capacity: Rated for residential and light commercial ZTRs (up to ~1,200 lbs total mower weight). Not for zero-turn tractors or heavy-duty commercial mowers over 1,500 lbs.
• Common gotcha: The lockdown works best on smooth trailer decking. Rough wood or expanded metal can cause the base to slide slightly—add a rubber mat under the mower if needed.

Should You Buy It

Buy this if you frequently transport a ZTR on a trailer and want a quick, tool-free way to keep the front wheels from swiveling during transit. It’s a solid upgrade over ratchet straps for caster control, but skip it if you have caster tires outside the 10.5"–12.5" range or need a permanent, bolted-down solution.
