Well this is my 100th post and feel it needed something extra. Slystr has come up with a quick and easy hoop tractor. It is very easy to build and could have other add ons in time. What I started with was 3 1x4x10's pressure treated 7 1/2" x 10' pvc schedule 40 5 packs of 1/2" 2 hole rigid strap I had screws at home so did not need to purchase. Total cost so far is right at $25. Cut one of the boards in half. Those will be your short sides and the other 2 your long sides. Screw the boards together to frame out the rectangle. I used one screw on top and one on the bottom. The one in the middle is what went through the rigid strap and helped strengthen the frame. Do this at each end. Measure the side boards and split the distance so that each bent pvc looks uniform. All of this took a half of an hour to get to this point. Like in the heading, Thank Slystr for this simple and easy low budget design. She is a plus to our forum. Will post more as it progresses and give time reports. Last picture has some bowing out on the sides so an extra board will need to be put in the middle or upgrade to 2x4's for more support and weight.
