Jeff,
My experience is that common sense goes a long way in these kind of situations...and by saying that I don't mean to imply that you don't have a lot of it! /forums/images/graemlins/smile.gif
Actually, I am not sure what I normally do with respect to shifting between four and two wheel drive. I usually keep my
B2910 in 4X4 mode, unless on hard pavement.
But I have found that when changing speed ranges, it is easier to shift between speed ranges when drifting to a stop, with the HST pedal centered. Without using the clutch. There is not grinding or anything like that, just a smooth transition between ranges, much easier than trying to change ranges with the tractor stopped and the clutch depressed.
Common sense tells me that IF the tractor shifts between 2 and 4 wheel mode, when drifting to a stop, without making a sound and doing so smoothly, it should not be a problem.
I have never, and don't plan to, tried to shift into 4X4 mode when on the run.
Best advice I know though, is to follow the manual when in doubt. It was after all written by those who built the tractor. /forums/images/graemlins/smile.gif
Who should know better?
