DVPARTS Yellow Mower Deck Leveling Gauge AM130907 Compatible with John Deere 325 335 345 D105 D110 D130 D140 D160 D170 E120 E130 E170 E180 Lawn Tractors

What It Is

This DVPARTS yellow deck leveling gauge (AM130907) is a simple tool for setting the cutting height evenly across your mower deck. Designed for select John Deere lawn tractors, it eliminates guesswork by locking the deck at a precise height for consistent, scalping-free cuts.

Fitment & Compatibility

• Direct OEM replacement for John Deere part AM130907.
• Compatible models: 325, 335, 345, D105, D110, D130, D140, D160, D170, E120, E130, E170, E180.
• Check your deck size: Works with 42”, 48”, and 54” decks on these tractors, but confirm your model’s deck linkage uses the same gauge slot.
• Measurement: The gauge has two notches—typically for 2.5” and 3.5” cutting heights. Verify your deck’s range matches.
• Aftermarket note: No modifications needed; bolts directly to the deck lift bracket.

Key Things to Know

• Quality: Durable yellow nylon plastic—holds up to UV and garage heat, but don’t force it if it doesn’t slide easily.
• Installation: Takes 5 minutes—remove the old gauge, slide this one into the bracket slot, and secure with the existing pin/clip. No tools required.
• Common gotcha: Some users report the notches are slightly off (by ~1/8”) on older decks—test with a tape measure after first install.
• Maintenance: Keep it clean; grass buildup can make the gauge stick and give false height readings.

Should You Buy It

If you own one of the listed John Deere tractors and want a quick, low-cost way to level your deck for even cutting, this is a solid buy. It’s not magic—just a simple plastic gauge—but at $9.20, it beats eyeballing or using a ruler. Skip it if you already have a working OEM gauge or prefer digital tools.
