What It Is

This Caltric AM133602 Deck Wheel Kit replaces worn-out anti-scalp wheels on select John Deere zero-turn mowers and tractors. The wheels keep the mower deck from digging into turf on uneven ground, preventing scalping and protecting your lawn.

Fitment & Compatibility

• Direct OEM replacement: Cross-references John Deere part number AM133602 (original equipment wheel kit).
• Compatible models: John Deere 1600, 647A, 657A, 717A, 727A, 737, 757, 7G18, 777, 797, 997, M653, M665, Z997R.
• Before buying: Verify your deck size and wheel mounting pattern. Measure the existing wheel stud diameter and spindle height—Caltric wheels match OEM specs, but older decks may have worn mounting holes. Check that your deck uses the same bolt pattern (typically two-bolt flange mount). If your deck has a single-bolt or keyed spindle, this kit will not fit.
• Kit contents: Four wheels with mounting hardware (bolts, washers, lock nuts). Does not include spindles or bearings separately.

Key Things to Know

• Quality: Hard rubber tires on plastic hubs. Good for residential use; may wear faster than OEM on heavy commercial mowing or rocky terrain.
• Installation: Moderate difficulty—requires removing old wheels, cleaning rust from spindles, and torquing bolts to 25–35 ft-lbs. Use anti-seize on bolts to prevent future seizing.
• Common gotcha: The included hardware may be slightly longer than OEM, so check clearance against the deck underside. If bolts protrude too far, they can catch debris or grass clippings.
• No grease fittings: These are sealed, non-greaseable wheels. If your original wheels had zerks, you’ll lose the ability to lubricate.

Should You Buy It

If you have a compatible John Deere zero-turn or lawn tractor with worn or missing deck wheels and want a cost-effective replacement that fits without modification, this Caltric kit is a solid choice. It’s not built for heavy commercial abuse, but for homeowners and light-to-medium duty mowing, it delivers reliable anti-scalp protection at half the price of OEM.
