Arnold Lawn Tractor Rear Tire Chains - 20-Inch

What It Is

The Arnold Lawn Tractor Rear Tire Chains (20-Inch) are heavy-duty tire chains designed to add traction on snow, ice, and wet grass for lawn tractors and garden tractors with 20-inch rear tires. They’re intended for winter use or slippery conditions where standard tires lose grip.

Fitment & Compatibility

Before buying, measure your rear tire’s actual height (not rim size) – these chains fit tires with a 20-inch outer diameter. Check tire width too: the chains accommodate tires up to 8 inches wide (common on many lawn tractors). They’re not brand-specific, so they work with most tractors using 20x8-8, 20x8-10, or similar tire sizes. Verify your tractor’s deck clearance – chains may rub against low-hanging decks or fenders. If you have a zero-turn mower, measure carefully; many lack space for chains. Arnold is an aftermarket brand, not OEM, but the fit is universal for standard 20-inch rear tires.

Key Things to Know

• Quality: Made from case-hardened steel with cross chains for grip. Reviews note they hold up well on packed snow but can wear faster on bare pavement or rocks.
• Installation: Moderate difficulty – you’ll need to lay the chains flat, drive over them, and tighten with the included tensioners. Expect 20-30 minutes for the first install; get a helper for easier alignment.
• Common gotchas: Chains can slap against the fender if not tensioned properly – use the rubber tighteners provided. They may leave small scratches on concrete. Check for tire valve stem clearance; chains shouldn’t press on it.
• Storage: Rust-prone if left wet. Dry them after use and store in a bag to extend life.

Should You Buy It

Buy these if you regularly mow or drive your lawn tractor on snow-covered or icy terrain and need reliable traction without upgrading tires. Skip them if you only mow dry grass or have tight deck clearance – they’re overkill for light use and could cause clearance issues on low-clearance mowers.
