Undercarriage
Durable versatility.
The D7E features an advanced low drive undercarriage
design for greater machine versatility in a wider range of
applications. Improved visibility, especially to the sides,
is only one of the several benefits of this highly efficient
undercarriage system.
D10-size sprocket bearings give the D7E the added durability
for a wide range of applications. Shock loads are directed
through the roller frame to reduce wear and tear on the
machine – and on the operator. The low drive undercarriage
configuration also allows the cab to be tilted for convenient
service access to the drive train system.
Heavy Duty Undercarriage
The heavy duty undercarriage system is well suited to
aggressive, high impact applications such as logging,
side-slopes, or working in rocky or uneven terrain.
The components are designed for extended wear life
in abrasive conditions and high impact applications.
The heavy duty track features improved track shoe design
– increased grouser height, enhanced penetration, increased
leading and trailing edge of shoe and increased track overlap.
Optional SystemOne™ Undercarriage
The optional SystemOne™ undercarriage has been proven to
reduce total undercarriage owning and operating costs up to
70 percent. SystemOne features lifetime sealed and lubricated
cartridges to eliminate bushing turns, and sprockets require
no replacement during the life of the chain. A rotating bushing
design allows the center tread idlers and sprocket segments
to last through at least two sets of track. An open and
smooth roller frame design reduces mud buildup and enables
easy clean-out. In addition, all SystemOne undercarriage
components are designed to work and wear as a system.
They deliver long, balanced wear life and require very little
service between undercarriage overhauls.
Undercarriage Configurations
STD – designed for versatility, this undercarriage configuration
works in a variety of soil conditions. It provides the proper
ground contact and pressure to maximize your productivity.
LGP – designed to work in soft and spongy conditions.
Wide track shoes, long track frames, and a wider gauge
increases track contact area and reduces ground pressure
for improved stability providing excellent flotation in
swampy conditions.
