Tail Wheel Assembly Fits King Kutter Replaces 4x15-tailwheel

What It Is

This tail wheel assembly is a replacement for the rear stabilizing wheel on King Kutter finishing mowers, rotary cutters, and similar tow-behind implements. It supports the rear of the mower deck, preventing scalping and reducing strain on the hitch during operation.

Fitment & Compatibility

Before buying, measure the existing wheel’s tire diameter (4 inches) and overall assembly height (15 inches from mounting hole center to ground). This assembly replaces the OEM King Kutter part number 4x15-tailwheel. It fits most King Kutter models with a 1-inch axle bore and uses a standard 5/8-inch bolt for mounting. Check that your mower’s mounting bracket is compatible—some older models may require a different offset or bushing. If your mower is not a King Kutter, measure the bolt pattern and clearance; aftermarket compatibility varies.

Key Things to Know

• Quality: The tire is solid rubber (no flat issues) but may be harder than OEM, leading to a slightly rougher ride on uneven ground.
• Installation: Simple bolt-on job using basic hand tools. Expect 15–30 minutes. You may need a new lock washer or thread-locker if the original hardware is worn.
• Common Gotcha: The axle bore is 1 inch, but some King Kutter models use a 3/4-inch axle. Verify your axle diameter before ordering—if mismatched, you’ll need a bushing or a different assembly.
• Weight: At about 5 lbs, it’s light enough to handle alone but sturdy enough for medium-duty mowing.

Should You Buy It

Buy this if you have a King Kutter finishing mower or rotary cutter with a worn or broken tail wheel and need a direct-fit replacement without modifications. It’s a solid, no-hassle upgrade for the price—just confirm your axle diameter and mounting hole alignment first. Skip it if your mower uses a smaller axle or you need a pneumatic tire for shock absorption.
