Possible Rear Leaking PTO Seal?

[rmonio]

My JD 4600’s rear PTO occasionally has the plate below the PTO - wet - and we are thinking it is due to a leaking seal. It hasn’t been severe and not a noticeable difference in the Hydraulic fluid level - but given the age (26 years), I’m thinking I should take it in and have it fixed at JD. Price was reasonable.

Thoughts?

Does it weep all the time or just for one specific implement. It could be a PTO shaft pushing the seal at a funny angle. I had that issue with my roto tiller. No other implements would cause it to leak.
