John, 

You asked that I pm you about the 1750. I'm pretty much planning a major engine rebuild as well as the 4wd. The tractor does run and drive but the engine is weak lots of blow by, poor starting, low oil pressure and noticable vibration that would seem like berrings and pin bushings. I bought it a year ago. It sat out side for 15 or so years. Found the exhost manifold nearly pluged with carbon. I changed the injectors and cleaned up the manifold. Put about 80 hrs on it this year. It runs ok once you get it started but the big cloud of blow by and the vibration in the enigne make me thing it's best to do somthing befor it's too late. Especially with the loads I put on it. Most of my intended use would put the tractor on a pto corn dryer which is 90-95% load for the 1750. It runs 1-1.5 gal hr cheaper than the 2255 which I have been using. About 4.5 gallons/hr to 6 gallons/hr. Thanks, Adam Suess
