No, they do not have a true "live PTO". When you step on the clutch the PTO is disengaged. However, you can duplicate how a "live PTO" works by using the shuttle shift to stop the tractor or change directions. The shuttle shift works like an automatic transmission and doesn't require the clutch to operate. It just takes some practice when using in close quarters. This of course assumes that your tractor has a shuttle shift and not a straight gear drive. This has been discussed many times in the past, but can be somewhat confusing if you have not operated a Yanmar before.
