Caltric 54in 60in 62in 72in Deck Gauge Arm & Wheel/Hub Compatible with John Deere 2210 4010 4110 4115 4610 4710 AM125172 x2

What It Is

This is a set of two deck gauge arms with wheels and hubs, designed to replace the front caster assemblies on zero-turn and lawn tractor mower decks (54 to 72 inches). It keeps the deck level and prevents scalping by supporting the front of the cutting deck during turns and over uneven terrain.

Fitment & Compatibility

Deck size: Works with 54", 60", 62", and 72" decks.
Model compatibility: Fits John Deere models 2210, 4010, 4110, 4115, 4610, and 4710.
OEM reference: Replaces John Deere part number AM125172 (sold as a pair).
What to check before buying:

• Measure the mounting hole spacing on your current gauge arm bracket (center-to-center).
• Verify the wheel hub bore diameter matches your spindle (typically 5/8" or 3/4").
• Confirm your deck’s front weight and clearance—this is an aftermarket part, so slight dimensional differences may occur.
• Not compatible with decks that use a single central caster or non-standard mounting brackets.

Key Things to Know

• Quality: Caltric is an aftermarket brand; build is adequate for residential use but may not match OEM durability under heavy commercial duty.
• Installation: Straightforward bolt-on for most models—expect 30–60 minutes. You’ll need basic hand tools and possibly a jack to lift the deck.
• Gotchas: The included hardware may not fit all John Deere models perfectly (some users report needing to ream or replace bolts). Check that the wheels spin freely before tightening.
• Wheel size: These are typically 4" or 5" diameter—measure your existing wheel to ensure ground clearance matches your terrain.

Should You Buy It

If you need a budget-friendly replacement for worn or missing deck gauge arms on a residential John Deere tractor with a 54"–72" deck, this Caltric set will work. It’s not built for commercial abuse, but for light-to-moderate use, it’s a solid value. Skip it if you require OEM fit precision or heavy-duty steel construction.
