I plan to connect a Jinma 6" chipper to a Kubota L5030 in the next week or so. The flywheel appears to be substantial, and most likely will continue to turn even though the PTO has stopped - Anyone know if there is any danger of damaging the tractor if the PTO being directly connected to the chipper. My concern is when the PTO is stopped and the flywheel of the chipper continues to spin. Do I need to connect through anything - e.g., torque limiters, or devices which allow the PTO to stop while the flywheel continues to spin. Also, any risk of damage if the chipper jams and the pto is continuing to run?
The pto shaft/ knuckles that came with the chipper should have a shear pin or slip clutch. If you are making your own, you need to include such.
How is your tractor designed? Many have a pto brake on them these days. It should handle the slow down when you disengage. I say 'should'. But, it will get wear, & I've heard of them breaking if you are at full throttle. You need to idle down to slow engine before turning pto off. An over running coupler would add the ratchet action.
If the chipper binds up & stops, you need a shear pin to break (need to size it right/ of the right grade bolt) or a slip clutch to slip (they tend to rust together if not used for long periods & offer no slip - need to loosen & make sure it spins before using). Or, the tractor will break. Something has to give.
