Controls

4. Controls
The grapple hydraulic system can be powered either from the
tractor hydraulic circuit or from its own self-contained power
pack. The controls function in the same manner, regardless of
the power source.
Before starting to work, all operators should familiarize
themselves with the location and function of all controls.

4.1 Main Directional Control Valve

The main control valve has five levers that control the stabilizers,
boom movements, and grapple. The two outer levers control the
position of the stabilizers, and the other three levers operate the
main boom, dipper boom, and grapple.
The control panel can swivel to either side to allow operation
from either side of the trailer tongue.
Auxiliary valves (when equipped) for winch, sliding axle (LXT95)
and hydraulic articulated tongue (LXT115) are mounted on front
of the control panel.
