How to build your own garden trailer

Updated February 21, 2017

A garden or utility trailer can cost upwards of £650. If you're up for a challenge, you can readily obtain the supplies to build a trailer from your supply shop and assemble it for a fraction of the cost of a retail model. Once you have assembled your garden trailer, you'll be able to load plants and gardening supplies and transport them around the garden with a tractor or ATV.

Purchase an axle kit from a supplier. The axle kit should include a type of suspension, either leaf spring or torsion bar, the trailer frame and a hitch. The weight capacity of the axle kit will depend on your intended use. A 3,500-pound capacity trailer will serve most home gardening applications.

Order the steel from a dealer or collect it from a local supplier. The cost of steel will be considerably cheaper to that of purchasing a road-ready trailer.

Saw off a length of steel with an abrasive saw and cut the ends at a 45-degree angle so that they can be welded together. Cut two pieces that are 5-feet long, and two pieces that are 10-feet long. Regardless of the trailer size, the length should be double the width to ensure proper balance.

Weld the two 5-foot pieces to the two 10-foot pieces to create the frame.

Tie a string diagonally from one corner to the opposite corner. Tie another string diagonally between the other two corners. If the strings touch, the frame is level and suitable for mounting on the axle.

Turn the frame upside down and mount the axle. The axle should be about 6 inches behind the centre of the frame. Mark the centre by using a tape measure, or place a mark at the string intersection. Placing the axle just off-centre will allow more tongue weight and make it easy to tilt the garden trailer when needed. The axle should be centred with the hitch. Use a tape measure to measure the centerpoint of the hitch to each wheel.

Mount the tongue of the frame to the crossbar just above the axle. The tongue is a 1-inch, solid round bar. Install gussets to reinforce the round bar and mount it between two 6-inch mounting tabs with 1-inch holes. This will allow the trailer to pivot.

Weld the iron fenders to the sides of the trailer. Weld two angle iron pieces together and create a C-channel. Weld it vertically to the rear of the trailer. This will act as a tailgate.

Apply primer and paint to the entire trailer to protect it from rust.

Measure and cut about 10 strips of plywood. The strips should be about 6 inches wide and 10 feet long. Place the strips vertically along the sides of the trailer.
