    Yep thats right. My Scag Walk Behind will not disengage the blades. (permanetly on)
    I have checked all the wiring and have replaced the PTO switch. I also have tried disconnecting any and all safety switches to get it to swicth off, but nothing. I on the other hand have just got over 500 hrs on it and according to the manual it says to adjust the air gap on the clutch....

    i know there are 3 main mounting points on the clutch but does any body have any ideas what it could be or what my next step should be?

    I have searched the forum.....

    When looking up under the unit at the clutch you have a lower bearing and a upper bearing, When the upper bearing fails/locks up it causes the deck to run continuously.

    Some of these bearings can be replaced depending on skill level and having proper shop tools/equipment for the job.

    Here's a post I made years back on clutch adjustment once the bearing failure is resolved; http://www.lawnsite.com/showpost.php?p=1463590&postcount=2
