This is not a pending project but wanted to do some scholarship to see what is possible and the smartest approach.
We had our septic tanks pumped just before the ground froze but I didn't get the holes filled in before the dirt piles were pretty solid (2 holes x 3 ft. deep....quite a bit of dirt). My neighbor was nice enough to offer his Kubota BX with mini/micro backhoe when he saw me out there with a shovel and pickaxe. That sold me on the utility of hydraulics. What I planned on taking most of the weekend took a little over an hour and saved my back I definitely have other uses for a small backhoe so I have my thinking cap on.
I was poking around the DIY backhoe plans at PF Engineering and CADPlans and see them describing connecting the backhoe via the Cat. 0 3pt hitch. Is a Cat. 0 hitch stout enough for something like a backhoe, and the weight and torques being applied? I would not question a Cat. 1 hitch or bigger, and love the idea of being able to connect/disconnect as needed via the pins and switch between attachments quickly, but also do not want to over-stress the connection points on the smaller hitch.
I was hoping to hear from those who have experience with the mini backhoes and have some insight as to how they should or shouldn't be attached to a large garden tractor.
