I change wheels on my BX
frequently, and see you have a B so the same very fast method I use should work for you.
Changing between Turf, Industrial, and Ag plus/minus two sets of 2" spacers means the height has to be at least enough to get the current wheels off and replacement wheels on, so there's not really "get it just off the ground and good" situation, and there are typically 3x the rear nuts as just a wheel swap.
I lift the front off the ground with the Front End Loader, then jack up the back at the point of the ball hitch mount, getting all 4 wheels off the ground at once and keeping the tractor stable as the FEL attachment doesn't allow the tractor to rock.
I sit on a
rolling seat at about the right height by the front wheel. An air impact gets the lug nuts off fast into a plastic container to keep them clean and undamaged. Lift it off and lay it down, then roll to the rear wheel and rattle-gun it loose. I use my toes to lift the wheel and pry it toward me, then set it down standing upright. The front wheel is light to pick up vs. the rear, I carry both to storage and return with a front and rear wheel.
I roll the rear wheel into place, relatively, trying to make sure the lugs and holes line up and put a
torque limiter on the impact wrench.
I sit down and roll the rear wheel over my toes (steel toe boots help as the toes aren't mushy) so I get the right height and hole position, walk my foot over, then use both feet to position the wheel. I hand start the lug nuts with both hands, then set the impact gun on low and rattle on nuts 1, 3, 5, and 2, then turn up the air half way and put on 4, then tighten 1, 3, 5, then turn the air to full and tighten 2, 4, 1, 3, 5 with a 2-second burst. With torque stick the lugs are generally tight the first time, on a truck/car I'd keep going around until the nuts stopped tightening.
I move to the front wheel and do the same. Then move to the other side, pull the wheels, and repeat the process. Economy of motion is important because I'll do this (plus spacers) to swap between a lawn setup and woods configuration in the same day, and with greasing the FEL, possibly swapping the bucket for grapple, and mounting a chipper (then loading it with saw equipment) I could spend a whole lot of time not getting jobs done.
---WHY:
It's fast and easy. There are fewer tools to get out/put away, less stuff to buy, store, and maintain, less stuff in my way when working. If I had a Grand L (and mid-mount mower) I'd likely use two 2x4s as a pry bar "jack" and pivot because they're fast, work great, easy to store, and also act as wheel chocks in a pinch, plus don't tend to damage stuff when they fall over. Put them in the shape of a biblical cross and it works great.
