J-Series Dozers are designed to run cool regardless
of what’s in the air or underfoot. Their highly
effective cooling system employs a hydraulic-
driven variable-speed suction fan that operates
only as needed for maximum power and efficiency.
For work in environments with lots of airborne
debris, an optional reversing fan automatically
back-blows to help shed debris from cooler cores
and side screens. So your 750J or 850J can work
long and hard without breaking a sweat.
Unitized mainframe with fl ush-fi t bottom guards combines
with tight-fi tting side shields to prevent debris from being
drawn into the engine compartment.
Perforations act as a “fi rst fi lter,” preventing entry
of most debris. Anything that gets past the fi ve-mm
holes also easily passes through the cooler cores.
No stacked coolers in these crawlers. Side-by-side
cores with wide fi n spacing reduce clogging and are
easy to clean.
