Tractor data.com lists no loader model for the B6100...actually no loader is listed for the next two progressions of the model...also no power steering which is important with a loader...!
IMO...with an aftermarket 3rd party loader the biggest issue might be the sub frame...
Dirt scoop is a good option as the tractor barely weighs 1000lb's...
You can maybe find a light weight front push blade to help with the dirt...is there any hydraulics on the snow blower?
Helpful but certainly not necessary. I ran my 275 for 15 years and never really wanted it for the loader. When I DID wish that I had it was when coming out of the woods pulling a good load. When one front tire slipped and the other grabbed, the steering wheel would about rip your wrists off your arms.
