As previously noted, weight transfer to the undriven wheel.

If anything, add weight to the front, not the rear.
I have no idea if there are off-the-shelf spike tires available, but
they are easy enough to make, especially for low-speed operation. We make
tires for ice-racing all the time, and they see far more abuse than
anything that plowmower could dish out ( ie, 100mph, 1+ lateral G ). The
only problem might be if you are plowing asphalt that is in good shape,
and you'd like to keep it that way. Metal tires might leave some marks.
