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.
