Building your own ATV plow can save you money. If done right, the snow plow can last for years. Just make sure to give yourself ample time to build the plow and follow the necessary steps to build it. One of the first decisions to make is whether you want a plow that throws snow to one side or to both sides. This is a personal preference and won't affect the steps listed below.
Purchase thick metal sheeting. This usually needs to be about 4 feet in length and able to withstand heavy use. This is the sheet that will be used as the primary plow in front of the ATV.
Bend the steel. Depending on whether you want the snow to be thrown to one side, or to both sides, you will need to bend the steel into a curve to match your criteria. To bend the metal, you will need a metal bending fabrication tool.
Build a mounting system that can attach to your ATV. The mounting system can be built to hook or hang onto the front metal bars of the ATV or you can use a chain to temporarily attach the mounting system.
Once this metal mounting system is built, weld the mounting system to the curved metal plow. After the mounting system and metal plow are welded together, mount the entire plow to the ATV for snow plowing.
Coat the plow with rust-proof paint. This will help keep the plow rust free and in good working condition for years to come.
