In Reply to: PTO question? posted by big rich on January 10, 2010 at 07:01:42:
There are 3 kinds of PTO. 1) Transmission PTO: runs off the transmission and has power only when the clutch is engaged. It is geared directly to the drive wheels when engaged and the inertia of an implement can keep the tractor moving for several feet when you step on the clutch pedal if you don't use an overrunning clutch. 2) Live PTO: uses a two-stage clutch;first engages the PTO, second the transmission. When you step on the pedal, half way down disengages the transmission, all the way down disengages the PTO as well. The PTO is disengaged from the transmission when the clutch pedal is pressed. 3) Independent PTO: The clutch pedal is for the transmission only. There is a totally different clutch (usually a lever) for the PTO. The PTO can be started or stopped regardless of what the transmission is doing. The transmission and PTO operate completely independently of each other. I hope that covers it.
