I am looking at a local tractor. The decals show it as a B6100 and the number on the frame lists it as a B6001, s/n 16646. What is the story on this difference? I have seen a thread by Vic that said it would be a B6100. How can that be? The tractor was repainted when the current owner bought it 20 years ago. It is stuck in FWD and the FWD lever just flops. I haven't heard it run yet and it hasn't run for a while. The paint is weathered, but it isn't beat up. It does have a belly mower and electric front pto. Any views on its value would be appreciated.
