This listing is for one cast steel rotary cutter tailwheel hub with industry standard four (4) bolt mounting and with tapered roller bearings and seals for a 1" axle bolt. This tailwheel hub is used my most manufacturers on their heavy duty 3-pt hitch rotary cutters but they also make a great replacement on lighter cutters offering much longer life. Designed to fit most 15" diameter and 21" diameter tailwheels with 4 bolt mounting and a 5" bolt circle, they come complete with all bearings, seals, centering bushings and mounting bolts, axle bolt not included.
