A beautiful B-1 that Ralph Doehrmann restored for his father. See his comments below.
"Grew up with AC and that's all dad has. 2 B-10, B1, B-12, lawn tractor that pivots in the middle, couple or 4 WC, WD, D-17, 180, and a host of machinery. Dad converted a Bolens front sickle mower to fit on the front of the B1. He used it to mow around corn fields to control weeds. Ran with concrete wheel weights. Really worked that tractor hard for a lot of years. Now it just gets used to till (tiller mounted all the time) and the B-10 mows."
