A video of how easy it is to transport and load on .
I started out by laying out the frame on the shop floor to figure out what angles to cut of the rough stock cuts .
I slide the axle under the rear to see where the rear section of framing will go .
Next I tacted in the box frame sections .
The rear I used the U stock for better axle support plus in this business the wheel/hub may get ripped off by a tree or bridge . Makes for and easy change of axle if needed .You could just weld it to the frame if you wanted . Also this is my first one . I would use large C clamps to hold the uprights in place and pre try it on sod cutter before drilling the holes . Also if your using taller tires it will change where the uprights will be . Keeping it closer to the ground will make it more stable and easier to pull sod cutter onto trailer .
The uprights If I make another one would use 1/4" flat stock next time .
A little paint and done for around $500 .
Close up of how it attaches to sod cutter . These are the actual factory pick up area for this sod cutter . The U channel below was to keep the wheels in place so it doesn't rock . Some times the depth of cut may keep it from fully loading so you may have to unadjusted .
