First, Try to down load a service manual. Remove center cover above hydro, as you stand on left side of tractor remove nearest little allen head plug. Keep pouring fluid in till it won,t take any more. Replace plug, remove spark plugs, jack up rear of tractor, put hydro lever in full forward & crank engine over.Will have to keep filling thru small plug until system is primed, may take several times. You will hear starter labor when it catches oil. Wheels will start turning, switch to forward hydro & should turn wheels forward. Raise & lower 3-point. System should then be purged. Remove little plug again, clean plug & put oil resistant sealer on plug threads & replace. Put spark plugs back in, fire it up at low throttle & run hydro forward & reverse, raise & lower 3-point & should be good to go. Be sure as you are going thru priming that you keep sufficient oil in transmission. Let me know how you turn out. StanD

      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
