Adjusting valves kubota bx220012/8/2022 I am sort of thinking of replacing PTO and Charge relief valves next since these control the pressures of the circuits that are indicating low I replaced the flow priority valve as some other forum posts indicates that that may be the cause, but there was no improvement. The high pressure side of the system (power steering, loader and lift) all seem fine. Additionally, I checked the PTO relief pressure, which is upstream of the charge relief, and it is also low. It is low (only about 20 PSI compared to spec of 40-70). I picked up some fittings and checked the charge relief pressure. Thinking the pump is probably fine since all other hydraulics work fine.Īnyone else had this experience? Any suggestions? I have the WSM and based on the troubleshooting guide I am thinking of checking the charge relief valve pressures next. I am not 100% familiar with the linage setup, but when I press the pedal it seems to be moving the input to the transmission to its full allowable travel. Cleaned Transmission Strainer - was very little in it I was able to limp it back by feathering the HST pedal.īelow are thing I have done after reading various forum posts. Half way there the tractor just stopped in its tracks and wouldn't move. The same thing started to happen so I shut down the brush hog and started back for the barn. The next time I used it I was brush hogging. I then changed the transmission filter thinking it may be clogged. Next time I mowed the same thing happened. Once I let the tractor cool down, it seemed to be OK again. After mowing for 45 minutes or so, the HST started to lose power and shudder a little. The first indication that there was a problem was ~month ago while mowing. FEL, PTO and three point hitch are working well and seem to have full strength. If I throttle up, I will lose all movement and it will sit there like I am in neutral. When I press on the pedal, it shudders very badly and moves slowly. The issue I am having is that the tractor will barely move in forward or reverse. Purchased about two years ago and has ran great ever since until now.
