Ive always used the Simplicity Hydrostatic transmission oil. It used to be a purplish red but now it is a golden brownish color. This is what Simplicity recommends in the owners manuals. However, on my 1992 Wheel Horse hydro the owners manual says to use 10W30 motor oil. I really don't know why there is a difference between the manufactures but I try to stick with what is recommended in the manuals by the manufacturer of the product. On the older Wheel Horses the red automatic transmission fluid you use in cars is recommended. Makes one wonder doesn't it? Sam

Sam, surpizes me to see someone recomends motor oil inplace of a hydrlic oil because the detergent in motor oil can foam up under hydro presure. I'm with you on manufactures recomendation. In Tok Alaska climate I run all synthetic's because it flows around here. Leaks easier, but I just add more. MPH

The Vickers T66 used in all Allis & Simplicity applications used Dexron 2 ATF. Later Sunstrand units used the hydro/power train oil & some of the current Eatons want 10w30 engine oil. We still use Dexron in the Vickers as was originally specified. Bill

The Sunstrand site (I know different from your trany) basically leaves the selection of oil up to the manufacture of the equipment that the pump goes in. Simplicity recomends that you use their hydro trans oil or a transmission type fluid. A non detregent oil should also work but I would use the oil recommended by Simplicity or your dealer PhilD

      Hello glad I got on this site. I hope to upload a couple of photos of my Simplicity Broadmoor 
      Model 707 Tractor. I have replaced all the belts on it and installed a new ignition switch.
      Have a mower deck which was in poor shape , repaced a couple of bushings and welded the
      deck where there was some holes. The tractor and mower deck came from a friend and the 
      mower deck metal was getting pretty thin. Some new metal was put in it and we also undercoated the underside of the deck. This was done by my friend Greg Toulman.
      I have not put the mower deck on the tractor yet, waiting for Greg to come home and give me a hand. Can you please tell me if there is a manual for the mower deck and where I could get one.
      I would also like to get some moon wheel discs as well.
      I will try and down load some photos of the tractor when my wife shows me how to. 
      I really love driving this tractor and also how well it is made compare today's tractors, especially the flexible rear end and the rollers.
      Tell the next time 
      Paul
