I have a subsoiler for a Cat 1 hitch, and I use it with a 37-HP tractor. I got it so I could hook it under roots and stumps and pull stuff out.
I had to modify it a little, because the ears that held the lower pins bent when I put a lot of stress on the subsoiler. I welded in gussets, and now I use a straight 3/4" bar that goes from one side of the subsoiler to the other instead of two short pins that direct torque to the pin mounts and which, themselves, are not hard to damage.
The subsoiler's shank is held in the subsoiler with two bolts that go through it. One at the top is heavy. The lower one is lighter. The bolts allow me to turn the shank around so the blade points backward if I want.
I keep snapping the lower bolt on the subsoiler. My question: is this thing supposed to be a shear pin, or can I go ahead and replace it with a stronger bolt?
I assume it would be pretty hard to hurt the tractor by pulling or lifting the subsoiler. I don't really care if I hurt the subsoiler, since it's easily replaced. I can't imagine Kubota's engineers making a 3-point hitch that can't be maxed out, but I have seen plenty of stupid engineering, so I may be wrong.
I managed to bend the bar that replaced the lift pins, but that was my fault. I let my Pat's Easy Change open up too much so it applied force to the ends of the bar. I plan to put in a new bar that has stops on the ends to keep the Quick Hitch close to the subsoiler. I guess I could have prevented the problem by using the stabilizer bar the Easy Change came with, but I couldn't be bothered.
I'm about to weld up a new shank which is more like a hook. I want something that will hold a root firmly instead of slipping off when I lift the rear hitch.
