Many users have also complained of having hydraulic problems with the tractor. More specifically, the problem they faced was directly related to four-wheel drive. According to these users with problems, the 4-wheel drive is constantly engaged and does not allow them to disconnect.
If you run into this problem, there are several things you can check. For example, we recommend that you check things like the 4WD solenoid, EMU, and wiring. You should also check the hydraulics itself, as well as the tractor brake switch.
