Ehh, my back doesn't bother me....
48" plow on a classic '65 Cub Cadet garden tractor here. I had a POS rider that died a couple years ago. Instead of buying new, I went old - cuts the lawn in the summer, sweeps the leaves in the fall and plows the snow in the winter and none of those new fangled safety devices to stop everything from turning off when you get off the seat!
