The way a tractor (at least yours) is built makes it so "unitized" that so long as you jack on solid metal the tractor will lift it in a really predictable and safe way- its not a big issue. Just jack ONLY THE WHEEL YOUR CHANGING.
The challenge is when you are swapping the rears around. You need to
have both off at the same time.
If I am removing only one rear wheel, then I use a rolling floor jack under
the draw bar bracket in the middle. Although, this will lift both rears
equally, the tractor will tip sideways when the wheel is removed. The
front axle provides no sideways stability since it pivots about its center
point. You can put wedges between the axle and subframe to stop this
action. You DO get some sideways stability if you leave the loader on
the ground, but I like to lift mine up to make the rear jacking easier.
If swapping the rears with only one floor jack, I first jack from the center as
above. Then I remove the wheel and place a jack stand under the wheel
flange. Then I move the floor jack as far to the other side as the remaining
tire will allow. Now jacking up to remove the remaining wheel has to be
done extra-carefully due to the side-to-side imbalance. That is why I have
moved to a 2-jack procedure.
