When the travel levers are pushed forward or reverse position, the travel spools in the main control
valve are moved to the forward or reverse travel position by the pilot oil pressure from the remote
control valve.
The oil from the each pump flows into the main control valve and then goes to the each travel motor
through the turning joint.
The return oil from both travel motors returns to the hydraulic oil tank through the turning joint and
the travel spools in the main control valve.
When this happens, the machine moves to the forward or reverse.
