Dave to remove the backhoe from the tractor I set both stabilizers down and lower the boom on the floor to slightly raise the backhoe. I then pull the front pins on the sub-frame mount for the 757C backhoe, yank the top link off and slowly pull forward away from the backhoe. Once I am just clear of the backhoe I idle the tractor down, set the parking brake, and place it in neutral. I then wheel the dolly under the backhoe and slowly lower the BH onto the dolly. The welded stops that I added to the dolly always place the backhoe in the same position time after time. I then raise and lock the BH boom, and raise the stabilizers. I have always used a short length of nylon rope to tie the stabilizers together least they will start to sag when the BH is stored. I also use one adjustable strap to lock the BH to the dolly. I then stop the engine and move all the BH controls to equalize the hydraulic pressure and disconnect the BH hydraulic lines. The dolly/backhoe can now easily be backed away from the tractor.
To install the BH on the tractor I park the tractor in the pole barn, raise the 3-point hitch, set the parking brake, and kill the engine. I then maneuver the backhoe/dolly as close to the tractor as needed and connect the backhoe hydraulic lines. I remove the rope that I use to tie the stabilizers together and remove the adjustable strap that ties the BH to the dolly. I then fire up the tractor, slightly raise the boom so that the boom lock can be removed, and lower the stabilizers in conjunction with the boom to lift and stabilize the BH while raising it off the dolly. I then slide the dolly out the rear of the backhoe and continue to mate the BH to the tractor in a normal fashion.
RobS when I first got my BH I tried setting the boom to the side once when I parked the backhoe but it seemed very unstable in that position. Plus once the boom is off to the side it can no longer be used to raise or lower the BH in a balanced position which is necessary for the docking procedure to the tractor. The boom more or less wants to flip the BH on its side when raising or lowering the BH which isn't good. I would not recommend parking your BH with the boom to either side.
