EQUIPMENT CHARACTERISTICS, CAPABILITIES, AND FEATURES
0002
The D7R Series II Dozer, classified as a tractor-dozer, is a self-propelled, fully tracked machine used for
high-production earth moving. The tractor-dozer is a self-propelled crawler with equipment such as a dozing blade
attachment which cuts, moves, and dozes material through forward motion of the machine, or a mounted attach-
ment that is used to exert a push or a pull force, such as a ripper or towing winch. Additional application may
include pushing scrapers during loading.
The D7R Dozer has a maximum stabilized drawbar force of 105,820 lb (48,000 kg) and a maximum vertical
drawbar load of 52,910 lb (24,000 kg).
WARN I N G
When operating equipment without the ROPSFOPS in the transport modes, operations
/
should be restricted to nearly level surfaces (less than 10% grade and/or side slope).
When operating equipment without the ROPSFOPS in the transport modes, operations
/
should only be conducted in very low speeds (forward or reverse).
When operating equipment without ROPS/FOPSin the transport modes, dozing, ripping
or winch tasks should be avoided.
When operating equipment without ROPS/FO S in the transport modes, operations
P
should be restricted from areas where heavy objects could fall on the cab area.
Failure to follow these Warnings may cause injury or death to personnel.
C AU T I O N
When operating on severe slopes, maintain engine oil level to FULL mark. Engine should
never be overfilled with oil. Damage to engine may result.
The machine is capable of operating on an ascending or descending slope of up to 60 percent (28 degrees) while
maintaining proper lubrication. When operating on severe slopes, quantity of oil in powertrain may be increased up
to 10 percent. After work on severe slope is completed, excess oil must be drained from bevel gear case. Notify
Field Maintenance. Prolonged operation with additional oil can cause high powertrain oil temperatures.
The D7R Dozer has fast, precise blade control without drift; superior visibility, convenience, and safety; and an
advanced cab design featuring joysticks for control.
