1/2" x 3" x 4" Deck Roller Anti Scalp Wheel Replacements for KUBOTA Replaces for K5763-46250 K5763-46251 K5763-46253 Fits for RCK48P-723Z RCK54-18Z RCK54-24B RCK54-29B RCK54-32

What It Is

This 1/2" x 3" x 4" deck roller anti-scalp wheel replacement prevents mower deck scalping (scraping grass tips) on uneven terrain. Designed for Kubota zero-turn mowers with 48", 54", or 60" decks, it replaces worn OEM parts to maintain consistent cut height.

Fitment & Compatibility

Measure your current roller – the shaft hole must be 1/2" diameter, roller width 3", and overall height 4". It directly replaces Kubota OEM parts K5763-46250, K5763-46251, and K5763-46253. Fits these specific deck models: RCK48P-723Z, RCK54-18Z, RCK54-24B, RCK54-29B, RCK54-32. Not compatible with other Kubota decks or general-purpose mowers. Verify your deck’s model number on the deck sticker (not the mower frame). If your deck uses a 5/8" shaft or different roller width, this won’t fit.

Key Things to Know

• Aftermarket vs OEM – This is a budget replacement, not Kubota genuine. Expect slightly less durable plastic than OEM, but adequate for residential use. Check for flash/molding burrs before install.
• Installation is simple – Remove cotter pin or retaining clip, slide off old roller, slide on new one, re-secure. No tools beyond pliers or a flathead screwdriver. Takes 5 minutes per wheel.
• Common gotcha – Some decks use a shoulder bolt instead of a smooth shaft. If your roller is held by a bolt head, this wheel may wobble. Confirm your deck’s mounting hardware style before ordering.
• Price per wheel – Sold individually at $12.99. You’ll likely need 2–4 wheels per deck. Check how many your deck uses (most Kubota decks have 2 rear, sometimes 2 front).

Should You Buy It

Buy this if you need a quick, low-cost fix for a worn anti-scalp wheel on a compatible Kubota deck and don’t require OEM durability. Skip it if you mow commercially, need exact OEM fitment, or your deck uses a different shaft size or mounting style – invest in genuine Kubota parts for heavy use.
