When I have my B2920 in four wheel drive should both front wheels spin when loading the bucket? Only one will spin at a time. Just making sure this is normal? I was thinking they would both be locked in? I guess that would make it hard to turn though.

Like iplumb says, open differential. It is like most 4WD systems. You can get "lockers" for trucks and my ATV/RUV have a selector to lock the front wheels, it does make them hard to steer, tears the ground up and put a lot of strain on the gears. You would really have to beef up the front differential on a tractor to stand the strain put on it by turning with a full bucket. I am sure it would also add quite a bit to the price.

One of the selling points of the M7040 is that it has a locking front differential. It is unusual to have one and was a reason a tractor that size was chosen.
It has been engaged and it is quite nice to be able to yank the tractor out of axle-deep mud. The huge front tires are a factor as well.
However, it is "limited slip" or "posi-traction" in car lingo so one wheel has to spin before the other decides to chip in to help out.
