I'm not sure there is gonna be a big upgrade from a BX to a B ... A L has quite a bit more weight, hence more lifting and carrying capacity ... Unless your needing PTO HP, I'd skip over the higher HP B's ... My brother has a cabbed B3030 for snowblowing ...
I think you can get more HP in the little tractors than your tractor tires can handle ... I have a SCUT and the 25 HP engine is more than capable even with filled tires and steel wheel weights, it can still spin the tires and get pushed around!
Here you can barely see the additional 275 Lbs of steel weight lifting plates I've added to the BH frame for additional weight, the rear blade still pushed me sideways!
