[AT] 90wt oil

Mon Aug 21 16:13:58 PDT 2006

Ralph:
When I worked for the MF dealer in OKC many, many years ago(1970), we 
serviced fords, IH, and MF and anything else that  the boss traded for. 
Fords up thru the hundred series that were not select-o-speed, and the 
Masseys used 90 wt mineral oil.  This included the TO series and the MF 
series up thru the 65's.  I had 2 85's one on diesel, and one on propane. 
The power steering pump drove off the side of the bell housing ahead of the 
transmission and worked the hydraulic pto clutch.  However, I cannot 
remember what we used in the rear end and hydraulic.  I do remember using 90 
wt mineral in the propane tractor so we had good steering and hydraulic. 
The old diesel was a low compression continental diesel that you usually had 
to pull to start.  If it was cold, you pulled it a ways with a shot of 
either, then kept it running.
