[AT] PTO shaft grease?

[Jim Becker]

A lot of those telescoping joints had a grease fitting but many others 
didn't.  I recall at least one, sometime in the past, that had an access 
hole in the shield for reaching the grease fitting.  You had to rotate the 
shield to look for the fitting.  I don't suppose the ones that are causing 
you trouble have them (otherwise they probably wouldn't be causing trouble). 
I looked online for a (relatively late model) Bush Hog manual to see what 
they recommend.  They said 8 hours for the u-joints.  For the telescoping 
joint, they said 40 hours on a pull-behind mower and didn't show a fitting 
on the joint.  For a 3-point mower, they never mentioned lubricating the 
telescoping joint.

You may not be putting on more than 40 hours a year.  But cleaning and 
greasing at least annually seems prudent.  Maybe that is all you really need 
to do.

I grease the universal joints before every use.  I only pull the shaft
apart and grease it, when it starts getting hard to move.  The shaft
that stuck on me was on a used rototiller, and I neglected to check the
shaft before I bought it.
