RaParts 15" x 4" Rotary Cutter Tail Wheel Tire Fits Bush Hog BH500 AC27 LML311A

What It Is

This is a 15-inch by 4-inch solid rubber tail wheel tire designed for rotary cutters and finish mowers. It replaces worn rear caster wheels on Bush Hog, AC27, and LML311A models, providing stable rolling support and reducing scalping on uneven terrain.

Fitment & Compatibility

Before buying, verify three things:

• Tire dimensions: Must be exactly 15" outer diameter x 4" width. Measure your current tire (not the rim) to confirm.
• Hub/bearing fit: This tire has a 3/4" inner bearing bore. Check your spindle or axle diameter – it must be 3/4" for a slip-fit. If you have a 5/8" or 1" axle, this won’t work.
• Model cross-reference: Directly fits Bush Hog BH500, AC27, and LML311A. For other brands (e.g., Woods, Land Pride), measure your mounting bracket width and axle diameter – this tire requires a standard caster fork with 3/4" axle.

OEM part numbers that match include Bush Hog 005000C and 005001C. Aftermarket replacement – no adapter plates needed.

Key Things to Know

• Solid rubber, no flat tires: This is a puncture-proof tire (not pneumatic). Expect a stiffer ride but zero maintenance.
• Installation is easy: Remove the old tire’s cotter pin or retaining clip, slide the new tire onto the axle, and re-pin. No special tools needed.
• Weight capacity: Rated for up to 500 lbs per wheel – fine for most 4-6 ft rotary cutters.
• Common gotcha: If your old tire had a different bearing width (e.g., 1" vs 3/4"), you’ll need to replace the axle or use a bushing. Measure twice.

Should You Buy It

Buy this if you have a Bush Hog BH500, AC27, or LML311A and want a no-flat replacement that bolts on without modifications. It’s also a solid choice for other brands with a 3/4" axle and 15x4 tire spec. Skip it if your axle size differs or you need a pneumatic tire for shock absorption on very rough ground.
