Caltric 60" 62" 72" Deck Rear Left Gage Wheel with Arm Compatible with John Deere 1550 1570 1580 1585 / x 2

What It Is

This is a rear left gage wheel assembly with arm for zero-turn mowers, designed to support the cutting deck on uneven terrain and prevent scalping. It’s marketed for John Deere 1550, 1570, 1580, and 1585 models with 60", 62", or 72" decks.

Fitment & Compatibility

• Deck size: Only fits 60", 62", or 72" decks listed above. Measure your deck width before ordering.
• Model check: Confirmed for John Deere 1550, 1570, 1580, 1585. Not compatible with other JD series (e.g., 1500, 1600) without verifying arm geometry.
• OEM cross-reference: This replaces John Deere part numbers M155519, M160176, or M160177 (confirm your original part number).
• Physical check: Measure the mounting bolt pattern and wheel arm length (approx. 8-10" from pivot to wheel center). The wheel diameter is roughly 6" – verify your deck clearance.
• Left side only: This is the rear left gage wheel. You’ll need a separate right-side unit for the other side.

Key Things to Know

• Low rating (2.1/5): Only 2 reviews, but both cite premature bearing failure or wheel wobble. Expect shorter lifespan than OEM.
• Installation difficulty: Moderate. You’ll need a socket set and possibly a pry bar to remove the old arm. Thread locker recommended on bolts.
• Common gotcha: The arm may not align perfectly with existing deck brackets. You might need to drill new holes or use washers for spacing.
• Material concern: The wheel hub is plastic, not steel. Avoid heavy side loads or rough terrain.

Should You Buy It

Only if you need a cheap temporary fix and can tolerate potential quality issues. For a mower used on flat lawn, it might hold up. But for commercial use or rough ground, spend the extra $30-50 on an OEM wheel assembly to avoid repeated replacements.
