New Aftermarket Tail Wheel Hub for Rotary Cutter 4 Bolt Hole 1" Axle Universal Fit

What It Is

This aftermarket tail wheel hub is designed for rotary cutters (brush hogs, finish mowers) that use a 4-bolt wheel pattern on a 1-inch axle. It replaces a worn or damaged hub to keep the rear of the deck supported and level during operation.

Fitment & Compatibility

Before buying, verify these three measurements:

• Axle diameter: Must be exactly 1 inch. Measure the axle shaft with a caliper—some older or non-standard mowers use 3/4" or 1-1/4" axles.
• Bolt pattern: Count the wheel studs—this hub is for 4-bolt wheels only. Measure the bolt circle (center of one stud to the center of the opposite stud) to confirm it matches your wheel. Common patterns are 4" or 4.5" center-to-center.
• Hub offset and depth: Check the hub’s mounting flange thickness and overall depth. If the hub is too thick or too shallow, the wheel may rub the deck or sit too far out.

This is a universal aftermarket part, not OEM-specific. It may fit brands like Bush Hog, Land Pride, King Kutter, and similar rotary cutters with a 1" axle and 4-bolt wheel, but always compare dimensions to your original hub.

Key Things to Know

• Quality varies: Aftermarket hubs are often cast iron or steel. Look for smooth machining around the bearing bore and stud holes—rough edges can cause premature wear or wheel wobble.
• Installation is straightforward: Remove the old hub (usually a single bolt or snap ring on the axle), slide the new one on, and secure it. Expect 20–40 minutes with basic hand tools. You may need a puller if the old hub is rusted on.
• Grease fitting check: Some aftermarket hubs include a zerk fitting for greasing bearings; others don’t. If your mower sees heavy use, prefer one with a grease port to extend bearing life.
• Wheel stud compatibility: The hub comes with studs, but double-check they match your wheel’s lug nut thread size (typically 1/2" or 5/8" fine thread). Mismatched studs can strip or loosen.

Should You Buy It

Buy this if your rotary cutter has a 1” axle and a 4-bolt wheel, you’re comfortable measuring to confirm fit, and you want a budget-friendly replacement instead of a pricier OEM hub. Skip it if you need a perfect OEM match, have an oddball axle size, or your deck is heavy-duty commercial—those may justify a sturdier OEM hub with better bearing support.
