Caltric Deck Gauge Wheel Arm Compatible with John Deere X465 X475 X485 X495 X575 X585 X595 X700 X720 X724 X728 X740 X744 X748

What It Is

This is a replacement deck gauge wheel arm from Caltric, designed to support the mower deck on John Deere X-series and 700-series lawn tractors. It keeps the deck level and prevents scalping by maintaining consistent cutting height, especially on uneven terrain.

Fitment & Compatibility

Before buying, verify your mower model: this arm fits John Deere X465, X475, X485, X495, X575, X585, X595, X700, X720, X724, X728, X740, X744, and X748. It replaces OEM part number M155673. Measure the existing arm length (approx. 8.5 inches from pivot center to wheel center) and check deck size (typically 48–60 inches on these models). Ensure the wheel itself (sold separately) uses a 5/8-inch axle hole—this arm does not include the wheel. If your deck uses a different mounting bracket or offset, this arm may not align.

Key Things to Know

• Quality vs. OEM: Caltric is an aftermarket brand; the arm is steel but may have thinner paint or slightly looser tolerances than John Deere OEM. Expect a functional but not identical fit.
• Installation: Easy—remove the old arm (one bolt and a cotter pin), slide on the new one, and reattach. No special tools needed, but a socket wrench and pliers help.
• Common gotcha: The pivot bushing hole on some Caltric arms is slightly undersized; you may need to ream it or lubricate heavily to avoid binding. Check fit with the mounting bolt before tightening.
• No wheel included: You must reuse your existing wheel or buy a matching Caltric wheel (e.g., part M155674). The arm alone won’t function without it.

Should You Buy It

If you need a budget-friendly replacement for a worn or bent gauge wheel arm on a compatible John Deere tractor and you’re comfortable with minor fit adjustments (e.g., reaming a bushing), this is a solid choice. Skip it if you want a perfect OEM match or need a complete wheel-and-arm assembly—buy the OEM arm or a kit instead. At $31, it’s a good value for the price, but verify your model and deck size first.
