I recently bought a 656 gas Hydro tractor and have found it to have some problems that may or may not be major. I found this site and I'm hoping someone here can help me. The first and main problem may be with the Hydro itself as the guy I bought it from said it was weak in high range. He said they had the tractor since 1989 and have only used it as a loader tractor for which it has never given them any trouble. He said the hydro was weak already when they got it but it worked good in low range so they did not do anything to it. He said they had never changed the hydro oil or filter because of the low hours they put on it. (Total hours on the meter show a little over 5,000.) I changed the filter but not the oil yet as it looks pretty good. Because of a badly leaking cylinder on the mower lift I have had to add about 5 or 6 gallons of oil during mowing so I am probably mixing two different brands of oil (it had Cenex oil in it and I'm using a generic farm store oil that supposedly meets CIH standards). The first problem I had is that after mowing hay for a while in the road ditch I turned up the ditch and the hydro started to slip and I had to back down and climb the ditch at an angle. The hydro is definately weak in high range as it will only pull the tractor itself on a faily level plane but starts to slip on grades. In low range it works fairly good if I keep the oil level full and don't go too fast. Works wonderful for mowing and square baling. I have read all the posts on this site pertaining to 656 problems but would appreciate any recommendations any of you can make as to where to start looking for problems before I go the route of replacing the hydro. The tractor really runs nice, has excellent rubber and other than the slipping problem is in very good shape so I hate to junk it. I already adjusted the foot/inch pedal to get it away from the platform but I don't think that was causing the slippage. The partsman at the local CIH dealership said something about a forward and/or reverse valve that might be part of the problem? He also mentioned a possible charge pump issue? I'm not a mechanical person but if I have some recommendations of where to start I can find the right people to work on it. I plan to have the flow rate checked ASAP as that is something I have read about in several threads on this site. From there on I need advice. Thanks for anything you guys can tell me. I'll have more questions later about the remote hydro system but will start a different thread for that. tlk
ps: The tractor will only be used to mow and square bale about 20 acres a year. The rest of the time it will be used as a loader tractor to feed a couple of horses and push a little snow. Probably will get used less than 100 hours a year.
