I feel your pain. I have a new MF 1758. Very disappointed in performance of hydro trans. when operating in mid-range. Can't use loader in Medium range hydro. Hydro slips before you can load engine to dig into pile. Then have to switch hydro to low range. Hydro in Medium range will not even slip tires in 2 wheel drive at the lowest engagement of the hydro in Med. range. Acts the same way when trying to pull any heavy load. The hydro max. speed in med. range is 8 MPH. Sure would think hydro should be strong enough to load engine before slipping. Had back to dealer and they checked hydro relief pressures and checked engine HP. Stated everything is in spec. So I have a 59 HP tractor that you can not do any heavy work with unless you have it in low range at max 3.5 MPH. The MF1736 ( 36 HP with same hydro) would then pull/push as much as the 1758 in mid range hydro. Can't believe MF would design Tractor with such power limitations in mid range hydro. Any other owners of 1758,1758, 1754,1749, 1742 experience issues with MF hydro's?
