New Holland T6010 PTO turning when off?

[agrotron]

Hi all

I have just noticed that the pto is turning when it is not switched on. I noticed it last week and today it was showing the speed when its not engaged? I have tried to stop it by hand but it wont.



Any advise much appreciated.

Will pto work ok under power, eng stopped can you turn shaft, if you put pto on to a machine will it try and turn even when off , i would suspect pto brake has failed or plates warped, has it done a lot of heavy pto work..

Pro brake band broken and/plates welded together

I have had valve blocked with metal bits on front pto.
