flymutt, can't comment on whether this is a good price or not but the B2150 is a tough little machine. I have the smaller B1550, about 14 years old now, little over 1,000 hours and only had to replace the battery. I've used and abused the little girl and she keeps running strong. Good tractor!
Depends on the hours and condition of it,But I will tell You I used to have one with a 60'' rear finish mower and I do know the one I had was a very good Tractor.
I remember back when this site first got started (actually, a couple of versions before "tractorbynet"). It seemed everyone had a B2150. It was THE tractor due to its versatility and solid construction.
Of course, prices vary widely depending on hours, condition, location, dealer vs. private, etc. (standard pricing disclaimer)
A year ago in June I looked at one on a dealers lot...1994,750hrs, 60"MMM and looked like it had been kept outdoors....$11,000. Front tires were worn out and rears looked to be about 50%
