502120 84612 84613 Mower Wheel Height Spacers Kit Compatible with Bush Hog RDTH60 RDTH72 MTH600 FTH480 ATH600 TH48-02 TH60-02 TH72-02, for John Deere Frontier GM3060

What It Is

This wheel height spacer kit (part numbers 502120, 84612, 84613) lets you adjust cutting height on Bush Hog RDTH60, RDTH72, MTH600, FTH480, ATH600, TH48-02, TH60-02, TH72-02, and John Deere Frontier GM3060 zero-turn mowers. It raises or lowers the deck by stacking spacers between the wheel hub and deck.

Fitment & Compatibility

• Deck size: Fits 48", 60", and 72" decks on the listed models.
• OEM vs aftermarket: This is an aftermarket kit, not OEM Bush Hog or John Deere. Measure your existing wheel bolt pattern (typically 4-bolt, 3" center-to-center) and the axle diameter (usually 5/8") to confirm.
• Measured clearance: Before buying, measure current deck-to-ground height and the gap between the wheel and deck when at your desired setting. Stacking spacers can cause tire rub on the deck or frame.
• Hardware included: Kit includes spacers and bolts; check if your mower uses fine or coarse thread (M10x1.5 is common).

Key Things to Know

• Stacking limit: Do not stack more than three spacers per wheel—excess height can strain the deck mount and cause belt misalignment.
• Installation: Jack up mower safely, remove wheel, slide spacers over axle, reattach wheel. Takes 10-20 minutes per wheel. No special tools needed beyond a socket wrench.
• Cut height range: Each spacer adds ~1/2". With three spacers, you gain about 1.5" extra lift. Verify your desired cut height before buying.
• Durability: Spacers are steel with a black powder coat. They resist rust but can warp if overtightened—torque wheel bolts to 50-60 ft-lbs.

Should You Buy It

Buy this kit if you need a cheap, easy way to raise or lower the deck on a compatible Bush Hog or Frontier zero-turn for rough terrain, thicker grass, or a specific cut height. Skip it if your mower already has adjustable height links or you need more than 1.5" of adjustment—spacers add stress to the deck and can void warranty on new mowers.
