I purchased a 4880 a year ago at an auction. The 903 is a good engine, but not in a truck application where you are up and down on the RPMs. When I purchased my 4880 I priced a rebuilt motor to help me decide what to bid, the cost was $10,000 US dollars. They are not cheap! Also if it has 3pt, it can be expensive to fix if the "black box" is bad. The 3pt is all electronicly controlled. This tractor will probably have a 3 speed power shift, note that it is not the same power shift that is in the 2700 series tractors. The 2700s had there share of problems, but this one can handle 375+ hp. We have had Masseys forever. 2745 with perkins V8 504, 1805 with cat V8 3208, and now a cum V8 903. The 4800s I think are great tractors for the money. Also note that they are costly to service. They hold a lot of oil. Steering and remotes share a tank. Trans has its own case. Front and rear axles have there own. There is also three pumps and a lot of filters. The plus side of this design is that if you hook up to a tool that has bad oil in the cylinders it will not mess up the entire tractor. All filters have sensors on them and lights on the dash. Pretty good considering the age of these tractors. If you have any more questions let me know. Not sure what you are running now but I think you will like the tractor.
