Ok I have a Gravley Commercial 12 that I picked up recently.
It had one irritating and potentially dangerous problem - the axle range control will not stay engaged. If you hit a good bump or go down an hill it will come out of gear. If you pull the handle again it goes back in. I figure that can't be good for the transmission. It doesn't matter if it is in hi or lo it pops out.
I took a look at it today and it has an adjustment on the bottom of the linkage. I have no idea how to know when it is adjusted properly.
Also I was going to take the tire off to be better able to reach the linkage. I pulled off the axle nut and the wheel would not come off. How do you pull the tire on this thing?
And where the heck is the serial number on it? I believe the engine was replaced at some time.
