Ok, so I purchased a used King Kutter Finish mower (side discharge) and a Land Pride Rb1560 Blade.
Both are used but overall good condition. My question is, the PTO shaft is a little worn, and I believe it is to have at least 8 inches of travel, and this one has 0 inches of travel. I was able to get it completely off the mower. It measures 32 inches. Not sure if it's extended at all or if that's the closed measurement.
Is there only one standard PTO for this type of mower, or are there multiple lengths? The shaft does fit on the PTO of the tractor, but it is unable to securely fit all the way forward to where the locking pin detents.
