Pump merge-dividing function
The pump merge-divider function senses the pilot pressure when the travel lever and work equipment
control lever are operated and judges if the travel and work equipment are operated simultaneously or
only the travel is operated.
When the travel is operated singly, a signal is sent to the merge-divider solenoid valves to divide the pump
discharge and improve the travel performance.
