I have tuned this baby up and try to keep my RPMs no higher than needed. I use it strictly to run my 9' haybine and it also runs the round baler. I may be plowing up some ground soon and could only imagine the gas it would burn plowing. I have found a 756 diesel close by that I am considering. I have read reviews from this site and by the sounds of it they are pretty good tractors. Rock solid engine and easy on fuel. This tractor is on a middle mans lot, he bought it on auction so there is really no finding out the history on this tractor. It has 9700 hours on it which is quite high on an original engine. Can't tell if the engines been worked on or not. Its clean as a whistle so likely been pressure washed, cant tell if there is any leaks or not. I can see a bit of antifreeze leaking from the rail just above the exhaust manifold. Looks to be a easy gasket to replace. The oil has been changed recently, can't tell ifs theres any sign of water in it or not. The price is right at $4800 but I just am a bit uncomfortable with all the unknowns here. Theres gotta be a reason that the last person who actually used this tractor sold it? I haven't heard it run yet, but I'm guessing that the engine needs rebuild. Whats a good way to tell if it needs rebuild or not while its on a dealers lot? Any other potential concerns about a tractor like this? I would like to try it out before committing to purchase but this time of year thats pretty tough. Lots of snow and frozen ground here in central MN. Tires are good but not matching. Ugly cab, no glass in it. But the tin work is very straight, needs paint. Seat is tough. All thoughts welcome and appreciated. Thanks [Reply]   [No Email]

First thing to do IMHO, would be, with engine cold, as in not started for a few days, crack the oil plug loose, and check for any antifreeze coming out past the threads. The Neuss engines were problematic for that. Next, see how it starts cold, if injection pump is weak or not timed properly, they can start hard, also if down on compression due to wear. Valve recession can cause this too. Don't be too alarmed if it slobbers fuel out around the exhaust manifold, common if they idle around too much, especially in cold weather. Check shifters and linkage for proper adjustment, and all the other items just like your 706. With decent care, that engine should have plenty of life left. Oh yeah, stay on top of fuel filter maintenence. Seen lots of those inj pumps trashed by water damage, especially on machines that sit unused a lot. [Reply]  [No Email]
