I talked to someone at Mobil and they said they had one type of grease that did not have the EP additive but it was sold in 5 gallon pails. I'm sure everything low would get lubed but am not sure about the top bearing and expansion. Maybe a small hole drilled in the dip stick? In my Gravely the oil would leak out as fast as I could pour it in and the grease cured it right up...no leaks! Thanks for the reply. Any other thoughts? Anyone know of a light grease with no EP additive? Said to say BCSSHOP I bought all new gears, shafts, bearings and seals for the PTO gear box and it leaked from day one just not real bad...I guess I am not a top mechanic....it is all shimmed up right and just the right amount of play so I hate to tear it down.
