I have a 1956 Case 401, the PTO will not stop turning. I have moved the on/off lever back and forth and it still keeps moving, the transmission sounds quite loud stopped or moving.
I do not have any implements to put on so that I can test to see if it is drag. However, it seems to be spinning quite forcefully in either position. Any suggestions to get the PTO to stop would be appreciated.

Pto won"t stop on that tractor because there is no pto brake,they never had one.

Thanks, Roger for the reply. However, my manual denotes that the hand clutch lever is pulled back to engage and forward to disengage.
The serial # is 8081218.
So my question is...
Is this lever suppose to engage or disengage? and isn"t working
Is this what they call pto creeping? (This pto is spinning very fast.

Thanks for your reply and help

The 400's without the pto Brake will spin when the lever is in the down (disengaged position)I bought ours in 1955 and it has always spun,now it spins with enough power to spin a 7 ft. bushog mower full speed empty, but the grass will stop it. Mel,is one of the finest knowledge men on here and he has told said the drag might involve warpage of the clutch plates which makes sense and thus would worsen with age....Its definately irritating and not safe but probably not harmful. I would be more concerned about the noise you are hearing, its maybe a bearing in the thru-shaft or other components that you want to repair before you get shaft or gear damage..
