the factory back hoes are frame mounted, not the 3 point setup which makes it a very strong setup. I really like mine, it is very responsive and does a good job of digging. We have very hard red clay and sometimes it takes some effort but it gets the job done. It only digs to 90" which is just under 8 feet. it is setup with the tractor hydraulics and it has two pins you pull to remove the unit. pretty easy and very solid. I put mine on a 4 x 6" lumber frame so I just drive over it, pull the pins and drive away. this way it isn't setting in the dirt. it also helps getting aligned when putting it back on.
