    Hills and Hydrostatic Transmissions

    Wolfman--thanks!!! I've always used Kubota filters and oil, so I'll do the same with the hydraulic system. When my cylinder seal burst I was afraid to do anything with my tractor without adding some fluid, so I bought the type specified at TSC (I just looked and it says Kubota UDT on the...

    Hills and Hydrostatic Transmissions

    Thanks for the advice. I'm going to stop and pick up a new drain pan to use for the hydraulic oil. We have an oil depository at our local convenience center, but I have no idea if they accept hydraulic oil. How do you typically dispose of it? The manual from Kubotabooks is just awesome. I...

    Hills and Hydrostatic Transmissions

    Thanks for all of the replies! Okay... let me try to be sure I answer them all. To begin, this behavior has existed ever since I purchased the tractor new from the dealer. At the dealership I tried the gear, glide and hydrostatic versions. I *loved* the HST due to easy maneuverability...

    Hills and Hydrostatic Transmissions

    Hi, everyone. I'm new here, and I've had this question nagging me since I bought my tractor back in the early 2000's. I have a Kubota 3430 HSTC (34 HP hydrostatic transmission compact tractor with cab), and from the first day of ownership it has struggled going up slopes of 5% or more in...
