Caltric AM136720 60D 60" Deck Gauge Wheels Compatible with John Deere X400 X500 X700 Tractor

What It Is

The Caltric AM136720 60D deck gauge wheels are aftermarket replacement wheels designed to support the outer edges of a 60-inch mower deck on John Deere X400, X500, and X700 series tractors. They prevent scalping on uneven terrain by keeping the deck level and reducing turf damage.

Fitment & Compatibility

Before buying, confirm your mower has a 60-inch deck (model codes ending in “60D” or “60”). Compatible with John Deere X400, X500, and X700 series tractors, including X485, X585, X590, X720, X724, X728, X730, X734, X738, and X749. These are aftermarket replacements for OEM part AM136720. Check your existing wheel bracket diameter and bolt pattern—these wheels use a 1/2-inch axle bolt and fit standard factory brackets. If your deck uses a different spindle or offset bracket (e.g., some older X500 models), they may not align properly. Measure the distance between deck mounting holes and wheel center to ensure clearance.

Key Things to Know

• Quality concerns: With only a 3.0 rating and 2 reviews, reports suggest inconsistent wheel roundness and plastic durability—expect shorter lifespan than OEM wheels, especially on rough terrain.
• Installation is simple: No special tools needed—just remove the old wheel, slide the new one onto the bracket axle, and secure with the included bolt. Takes 10 minutes per wheel.
• Check bracket condition: If your existing brackets are bent or rusted, the new wheels may wobble or bind. Replace brackets separately if needed.
• Adjust height: Gauge wheels should sit just above the ground (1/4 to 1/2 inch) when deck is at cutting height—adjust using the bracket slots.

Should You Buy It

If you need a budget-friendly replacement for worn OEM gauge wheels on a 60-inch John Deere deck and don’t mind potentially shorter lifespan or minor quality issues, this kit works. But for heavy commercial use or if you want trouble-free longevity, stick with genuine John Deere OEM wheels—they’ll cost more but last much longer and fit perfectly.
