John Deere Original Equipment Strap #M111150

What It Is

The John Deere Original Equipment Strap #M111150 is a replacement lift strap designed for select John Deere lawn tractors and zero-turn mowers. It connects the deck lift mechanism to the mower deck, enabling height adjustment and supporting the deck during operation.

Fitment & Compatibility

Before buying, verify your model’s deck size and year. This strap fits many John Deere models with 42–54 inch decks, including the X300, X500, and Z500 series, as well as older 100 and 200 series tractors. Check your owner’s manual or existing part number—this is an OEM part, not a universal aftermarket piece. Measure your old strap’s length (typically ~12–14 inches) and hole spacing to confirm. It will not fit most non-John Deere brands or older two-piece strap systems.

Key Things to Know

• OEM quality: Built to John Deere specs with reinforced rubber and metal ends; lasts longer than generic straps that may stretch or crack.
• Easy install: Usually a 10–15 minute job—no special tools beyond a socket wrench or pliers. Watch for rusted bolts on older decks.
• Common gotcha: If your deck sags or won’t lift evenly, check the strap for cracks or wear before assuming a pulley or cable issue. This strap is often the culprit.
• Price vs. aftermarket: At $15, it’s a few dollars more than generic straps, but the fit and durability justify the cost for frequent users.

Should You Buy It

If you own a compatible John Deere mower and notice deck sag, uneven cut height, or a snapped/rotted strap, this is the exact replacement you need. It’s a simple, affordable fix that restores proper deck function. Skip it only if you have a non-John Deere brand or a deck with a two-strap system (this is a single strap).
