Asking for confirmation the resistance reading for a good blade clutch should be 2-4 ohms, right?

Thanks in advance,

Hi Bartles,

Yes, 2-4 Ohms is the standard I use for electric PTO clutches. Most PTO clutch problems I see are wiring related or the PTO switch has worn out contacts. Any higher reading indicates the winding are heat damaged. If the meter reads "OL" or infinity, the winding has failed "open" due to a break.

Thanks! The owner has thrown new parts ($$) at everything that has a plug...then calls and asks what could it be....heard that before?

Appreciate the help,

H Bartles,

A JD 737 zero turn I recently had trouble with actually turned out to be a corroded main fuse that was heating up. It never blew the fuse, but it was dropping Amperage across the fuse and the PTO clutch would kick off and on rapidly. I replaced the fuse holder and fuse, and the problem was resolved.

Well folks like this guy keeps the parts businesses healthy.

A lot of people just throw parts at it hoping they find the one that fixes it. Wrong way to fix it and it can get expensive to fix that way.
