[TenTec] TT PTO stuff

[Bwana Bob]

My PTO and a rebuild kit I bought had green grease.  Earlier posts said 
that Ten Tec called it "open gear grease" that they bought at the local 
co-op. Some specs!

What is needed is a heavy (high viscosity) grease that won't dry out.  I 
tried lighter greases and they are not sticky enough; the spring tension 
on the PTO shaft causes the knob to turn spontaneously.
