    i have a bobcat a300 approx. 3300 hours on it. i was using the trencher in the forward motion and needed to reverse the motion and it would not go in reverse. so basicly the front aux hydraulics only work in one direction...it is a joystick controlled unit, so the aux hydraulics are controlled by the right joystick there is a toggle like switch on top and a constant trigger on the bottom of the joystick...any help would be greatly appreciated!!!

    Have you tried another attachment to make sure it is not your trencher that has the issue?

    Is it throwing any ACS codes? It sounds to me like you may have a sticky valve body,and/or, a faulty actuator.
