[quote=&quot;oleblu&quot;:3ajuusbx]To be honest, I've never worked on the PTO of a 550. If it's like the Fleetlines  Supers or 880's, the shaft from the flywheel turns anytime the engine is running. That gives you &quot;live&quot; PTO. At the rear of the tractor there should be a large &quot;round&quot; cover where your PTO lever goes in. Inside that cover are the PTO clutches and a mechanism to take the PTO in and out of gear. I think that is the area you need to look at.

 I'll take a looks at my IT manual and see if it's got anything in there.[/quote:3ajuusbx]

I have the I&amp;T manual.  The only thing it mentions about the clutch is changing it, which you have to split the tractor to do.  I am just wondering if I can access that area by pulling the steering box and what I THINK is a removable access area.
