Can't help much with the loader question. Some have brackets that unbolt when supported, some will self support or use a kickstand and the pins and hydraulics can be separated easilly leaving just the subframe on the tractor. Mine(custom made) is self supporting I fully dump the bucket and put the bucket edge on the ground. I can then remove the two lift arm pins and remove the control valve from the loader subframe. I then raise the loader/extend the lift cylinders. This rolls the loader forward till the bucket opening is flat on the ground. The bucket with lift arms will freestand like this. Once standing free, I remove the lower cylinder pins, shut off the tractor and take the loader valve out of circuit and connect up all QC's to send fluid to 3PH then startup and back away. It takes a floor jack and some big wrenches to remove the subframe.
