IMPLEMENT HYDRAULIC SYSTEM
The implement hydraulic system controls operation of dozer. All hydraulic pumps on machine are assembled in
series and are mounted directly to engine flywheel housing. The implement pump supplies oil to hydraulic cylinders
for dozer blade. The cooling fan pump provides oil flow for on-demand cooling fan. The cooling fan pump also pro-
vides charge pressure to left hydrostatic pump and additional pressure to load sensing boost for the implement
pump. The load sensing boost improves the cycle time of the implements.
The implement hydraulic system and hydrostatic powertrain system share a single hydraulic fluid tank.
