When the bucket and travel functions are operated, simultaneously the bucket spool and travel
spools in the main control valve are moved to the functional position by the pilot oil pressure from the
remote control valve, and the travel selector spool is pushed to the up by the oil pressure from pilot
pump. The oil from the P1 and P2 pumps flows into the travel motors.
The oil from the P3 pump flows into the bucket cylinder through bucket spool via the travel selector
spool.
The bucket is operated and the machine travels straight.
