New Deck Leveling Gauge for John Deere AM130907 TY15272 MTD 490-900-0041 Cub Cadet Troy-Bilt 490-900-0041 MOK30-0015 Stens 750-442

What It Is

A deck leveling gauge that replaces OEM part numbers AM130907, TY15272, 490-900-0041, MOK30-0015, and Stens 750-442. It’s used to set the cutting deck height precisely on John Deere, Cub Cadet, MTD, Troy-Bilt, and similar lawn tractors, ensuring an even cut across the mowing width.

Fitment & Compatibility

• Check your OEM part number – This gauge is a direct replacement for AM130907 (John Deere), TY15272 (MTD), 490-900-0041 (Cub Cadet/Troy-Bilt), MOK30-0015, and Stens 750-442. Verify your existing part number matches.
• Deck size – Works on decks from 38 to 54 inches, but the gauge itself is a universal leveling tool, not deck-specific. It fits most tractors with a deck lift linkage that uses a threaded rod and adjustment nut.
• Measure the rod diameter – The gauge’s slot fits a standard 3/8-inch or 10mm adjustment rod. Measure your rod’s diameter to confirm compatibility.
• Brand/model – Fits Cub Cadet, MTD, Troy-Bilt, Yard-Man, Huskee, and John Deere (select models with the AM130907 system). Not for zero-turn or walk-behind mowers.

Key Things to Know

• Quality – Made of stamped steel, similar to OEM. Some users report the paint chips easily, but it doesn’t affect function.
• Installation – Simple: slide the gauge over the adjustment rod, tighten the nut to lock the deck at the desired height, then remove the gauge. No tools needed beyond a wrench for the nut.
• Common gotcha – The gauge only sets one side at a time. You’ll need to level both sides separately, then check the front-to-rear pitch. Don’t skip the second side.
• Accuracy – Markings are in 1/4-inch increments. For precise leveling, use a tape measure or ruler to verify the actual blade height after adjustment.

Should You Buy It

If you have a compatible tractor and want a quick, repeatable way to level your deck without guessing or using a ruler each time, this $9.20 gauge is a no-brainer. It’s especially useful for seasonal adjustments or after blade changes. Skip it if you already own a digital inclinometer or prefer measuring with a tape.
