i have a 555b backhoe and it will not move everything else works fine i could did a hole but just can’t move my machine i was wondering if i could completely remove the transmission dump valve so i could eliminate that i have it broke into already i wished i had checked some pressures before but i didn’t so any help would be appreciated
did you figure this out yet? on my 555D once the break pedals got stuck when press down to the floor. I couldn't move and i thought something really bad happened... but i was able to pull up on the break pedals and get i t back to the shop. the other thing would be to check the trans fluid condition and level. if its too low or bad the hydraulic clutches in the transmission won't engage or be too weak, and you wont move.
