This question is for Dr Allis (or other actual mechanics familiar with these tractors) continued from another thread. For the hydraulic PTO tractors, is it safe to run them in the middle position for extended time? I checked 3 of our tractors and none actually feel like there is a notch for neutral position such as the 200. I don’t want to tear up these tractors if it’s slipping a clutch or something in that nature. I generally try to engage easy at low rpm or use the foot clutch so I don’t blow gear boxes on equipment (would help if there is a soft start adjustment that can be made). I know the other week, I through on the PTO while hooked to a Tedder and thought the gear box was going to blow because I had a little too much throttle on that pass. Going back to stopping, similar thinking. If by design, it’s only ok to drift stop, that’s better than I’ve done in the past. I do know that we have had the PTO brakes fixed on all three 185’s over a 40 year span, just guessing around 2500-3000 hours or so. Thanks for the education, Kevin

Middle position to ease into clutch engagement and to let a machine coast to slow down before applying the brake. So, it is momentary, not all the time. Some machines take longer to coast to a stop (forage blower) and start up from a dead stop to full speed (forage blower).
The closer you have the engine to a slow idle, probably the better for engage and disengage.
