Caltric AM130907 TY15272 Deck Leveling Gauge Compatible with John Deere 240 245 D105 D110 GT225 S100

What It Is

The Caltric AM130907 TY15272 is an aftermarket deck leveling gauge designed to help you set the cutting height evenly on both sides of your mower deck. It’s intended for use on John Deere lawn tractors and zero-turn models with a stamped or fabricated deck that uses a pin-and-hole height adjustment system.

Fitment & Compatibility

Before buying, confirm your mower model and deck size. This gauge is listed as compatible with John Deere 240, 245, D105, D110, GT225, and S100, but it also fits many other Deere models using the same OEM part numbers (AM130907 or TY15272). Check that your deck uses a single-pin height adjustment (not a dial or lever) and that the gauge’s hook and slot dimensions match your deck’s lift arm bracket. Measure the distance between the pin hole and the deck shell—if it varies from the gauge’s design, it won’t work. For non-Deere models, cross-reference your OEM part number to AM130907. The Caltric is an aftermarket replacement, not OEM, so fitment may be slightly looser than the original.

Key Things to Know

• Quality concerns: With only 2 reviews and a 3.0 rating, some users report the gauge is thinner and less rigid than OEM, which can flex during use and give inconsistent readings.
• Installation: Easy to install—just slide it onto the deck lift arm and adjust the pin. No tools required, but you’ll need a level surface and a tape measure to double-check the height.
• Common gotcha: The gauge may not sit flush on decks with heavy rust or paint buildup. Clean the bracket area first. Also, it only sets the deck level side-to-side—you still need to set the front-to-back pitch separately.
• Limited utility: If your deck uses a different height adjustment system (e.g., foot pedal or single-lever), this gauge won’t work. It’s strictly for pin-style decks.

Should You Buy It

This gauge is a budget-friendly option for DIY owners of compatible John Deere models who need a quick way to level their deck without spending $20+ on OEM. However, if you mow frequently or need precise, repeatable results, the higher-rated OEM gauge (part AM130907) is worth the extra cost for better build quality and consistency.
