I haven't seen much snow work done with a tractor, but I have seen a lot of truck plowing on my driveway. I would think, it might be less exciting (a good thing IMO) on a tractor.
Certainly the current garage would work if I just get a plow for my truck. That's really the question right now, what garage do I build.
I went to the local Kabota dealer on my lunch break. I took a tape, I was trying to see how much length is added with the front bucket. Looks like ~3+ feet.
The B01 Series, maybe the B2601, with bucket on the floor is 11 feet long
The LX Series, maybe the LX2610 or LX3310 is 12 feet long
Even with the B series it does look very tight. And I have to keep the blower somewhere too.
If I build the 28x34 I think I can:
Get UTV with a blade in year one, and stay with Andy for plowing.
In year 2 and beyond:
Stay with what I did in year 1
Consider a small tractor with snoblower
Consider blade for the truck
Or go to 30' wide now.
