I had been looking at making a 3-point frame for my drag harrow when I ran across this unit. Looked to be pretty solid and a good price so I ordered it. Delivery was pretty quick. The unit is made out of heavy steel and the surfaces all have a heavy coat of paint. Should hold up for years.
As for assembly, the instructions leave a lot to be desired. Poor picture quality and zero written assembly steps. I got it put together as I'm sure anyone with any mechanicaly knowledge could. But it would have gone much smoother and quicker with better instructions.
Unit performed well once attached to my tractor. I will probably make a few mods to make it easier to switch which way I am dragging my harrow. Overall I'm satisfied with this piece of equipment, but work on better assembly instructions.
