Hey!
Kinda bumped into this site by accident.
  We have an old  Lull powered by an Oliver. The model number is 702-31
It was running good when we parked it bout 5 yrs ago. We were talking this morning about cutting it up for scrap and saving the engine and transmission out of it. Are they worth saving? With all the new OSHA guidelines on job-sites it isn't worth it for us to keep it. We also have the original owners manual here some place.
