It is mounted directly to the trailer frame or chassis and commonly used without a functional suspension. Replacement axles can be fashioned from a piece of round bar and U-bolts.

A utility trailer axle is a lightweight trailer axle designed to carry small loads of lawn and garden trash, as well as small hand tools. Commonly used behind a lawn tractor, the utility trailer is meant to bridge the gap for the yard worker by carrying all the tools and materials needed for a small project. The utility trailer axle is mounted to the trailer and supports the wheels and tires. Commonly used without a functional suspension, the utility trailer axle typically mounts directly to the trailer frame or chassis with bolts. Wheels are commonly held on with a flat washer and a cotter pin.

Utility trailers are commonly used to haul yard waste or planting supplies behind a small tractor. The trailer uses a utility trailer axle to hold the tires and wheels that allow the trailer to be easily pulled. The utility trailer axle design prevents large, heavy material loads from being pulled on the trailer as the lightweight axle could bend or break under the stress of the load. Tires used on a utility trailer often resemble tires used on a wheelbarrow, with a single-axle rod running through the center of the wheel and a flat washer and pin holding the assembly onto the utility trailer axle. .

It is unusual for a utility trailer axle to be mounted on a spring type suspension, as most are attached directly to the frame or even the bottom of the trailer bed. Occasionally a dump type utility trailer will incorporate a small frame under the trailer to allow the trailer to remain hitched to the tractor while being unloaded. In this type of design, the utility trailer axle typically goes through the subframe and can be welded to the subframe where the axle exits the metal stock. Other axle designs use metal tabs attached to the axle to bolt the axle to the underside of the trailer.

Rarely does a utility trailer axle break, however some well known manufacturers such as Sears and John Deere make replacement axles for some models of their utility trailers. A replacement axle can often be fashioned from a piece of round bar and a pair of U-bolts. The round bar should be the right size to go through the wheels and long enough to overhang the sides. of the trailer enough to allow the tires to turn freely. The bottom of the trailer can be drilled out and the U-bolts run through the trailer and over the axle, then tightened securely to hold the assembly in place.
