Once mounted correctly, you do not need to remove the sub-frame or even use any tools to go from backhoe to three-point use and back to backhoe. In a race (don't ask me how I know this), a backhoe can be removed in less than 2 minutes. Takes a little longer to hook up as you have to get lined up squarely to reattach.
I had to remove it because the sway bar or stabilizer mounts, bolt up to the same place that the backhoe sub-frame bolts to, just below the rear axle. The mounts were in a bucket along with some other parts that go with the tractor when it was delivered so I know they were on the tractor at one time. I could tell by the paint outline where they were mounted.
The 3 point hitch would probably be ok. I just haven't tried it along with the backhoe.
The backhoe mounting is to have a provision for the stabilizers. Changing between backhoe and a fully functioning three-point should take no tools. Other than maybe a hammer if the pins are wedged in tight.
I don't mean to hijack this thread, but I'm curious as to how this should be done. If I can keep the sub-frame mounted all the time it would be great.
Here are some pics of the sub-frame that I have along with the sway bar mounts attached to the tractor. The way they're laid on the floor, is the way they came off, meaning the one on the left was on the left side of the tractor.
Huh, yeah yours is different, like I said, mine is a woods backhoe and subframe. They made provisions in their subframe to mount the stabilizers. Can't recall exactly how it looks, I'll try to get you a picture this weekend. You'd think Mahindra would have done the same.
