Plastic Deck Wheel Fits John Deere Lawn Mowers w/ 60" and 72" Decks

What It Is

This is a plastic deck wheel designed to support the outer edge of 60-inch and 72-inch John Deere mower decks, preventing scalping and reducing deck wear on uneven terrain. It’s a direct replacement for the factory wheel on residential and commercial zero-turn and riding mowers.

Fitment & Compatibility

Before buying, confirm these three things:

• Deck size: Only fits 60" and 72" decks. Does not work on 48", 54", or other sizes.
• Model series: Common on John Deere Z900 series (Z920A, Z925A, Z930A, Z950A, Z960A, Z970A) and older 7000 series (757, 777, 797). Also fits select 60" and 72" decks on X700 series and 1025R/2025R with optional deck. Not compatible with standard 42" or 48" residential decks.
• OEM equivalent: Replaces John Deere part numbers M155933, M155934, or M155935 (confirm your specific deck’s bracket style – the wheel itself is the same, but the mounting arm may differ).
• Measurements: Wheel diameter is approximately 4.5 inches, axle hole is 0.5 inch. Verify your original wheel’s diameter and axle size matches exactly.

Key Things to Know

• Quality vs OEM: This plastic wheel is lighter and less durable than the factory steel-reinforced wheel. It will wear faster on gravel or rough ground but is fine for flat lawns.
• Installation difficulty: Easy – remove a single cotter pin or bolt, slide off old wheel, slide on new one, and re-pin. No special tools needed.
• Common gotcha: The plastic hub can crack if over-tightened. Hand-tighten the retaining bolt only until snug; use a lock washer but do not torque.
• Lifespan: Expect 1–2 seasons of normal residential use. Replace both wheels at the same time to keep deck level.

Should You Buy It

Buy this if you need a cheap, quick fix for a worn deck wheel on a 60" or 72" John Deere mower and you mow mostly flat, well-maintained lawns. Skip it if you mow rough, rocky, or commercial-grade terrain – spend the extra $10–15 for the OEM metal-reinforced version for longer life.
