T190 shutter or chatter when driving

Im having an issue with a 2007 t190 i just purchased i was wondering if anyone else has had this issue. while moving forward or backward the hydraulics seem like they are chattering sometimes it gets pretty jumpy. Its kind of hard to explain but it seems like the hydraulics load up then are too fast so the engine tries to catch up then it loads up again and over again and gives me a jumpy kind of ride like there is some kind of cushioning valve or accumulator valve in the pump thats not working. Any help is appreciated

Check the case drain filters, but even check/replace the hub oil. If you drain it, look for metal particles.
Sadly chattering feelings from the drive motors on a T machine is not a good sign. The hub oil needs to be replaces at set times or the bearings can fail, this causes extensive damage.

i dont think its just in the drive motors i can also get it to do it with material in the bucket if i move it up and down quickly. Seems like under any load it does it either bucket or drive, just is more pronounced in the drive motors prob. Ill try and upload a video

The tracked machines will act like that with inexperienced operators. Try it at full throttle, with both sticks moved as far forward as they will go. My bet is that it will go fine. There's the possibility of induced oscillations, where a jerk of the machine will jerk your hand which will cause the machine to jerk even more. Sometimes I have to rest my hands lightly to keep from causing the machine to buck like a mule.
