CHAPTER 2
TRANSPORTABILITY DATA
Section I. GENERAL
2-1. Scope
This chapter provides a general description and
identification photographs of the D7 tractors as
well as transportability data necessary in moving the
tractors.
2-2. Description
The D7 tractor is a commercial, track-type tractor
modified for the US Army. It is diesel-engine-driven,
has a rollover protection system (ROPS) canopy, and
has a straight blade. It also has either a rear-
mounted towing winch or a ripper. However, the rip-
per and winch are not interchangeable. The ripper
can be mounted only on D7 tractors equipped with
ripper mounting devices; the winch can be mounted
only on D7 tractors equipped for a winch. Figures 2–
1 and 2-2 show the D7G with ripper and the D7G
with winch, respectively. The D7E and D7F model
tractors are similar in appearance to the D7G.
2-3. Transportability Drawings
Figures 2–3 through 2–6 are detailed side- and end-
elevation transportability drawings of the D7G with
ripper and the D7G with winch. These drawings
show dimensions and lifting and tiedown provision
locations with load rating capacities. The D7E and F
models have similar features except the weights and
dimensions vary as shown in table 2–1. Also, the D7E
and F models have one extra tiedown provision on
the track roller frame. The provision is located
between the other two multipurpose provisions on
each side.
Section II. CHARACTERISTICS AND RELATED DATA
2-4. General Transportability
Characteristics
The data in this manual apply to the model number or
national stock number (NSN) shown. Changes in
model number or NSN may affect the loadability of
the item as related to the guidance in this manual.
Dimensions and weights are given for both opera-
tional and reduced configurations. The reduced D7
configuration consists of removing the ROPS,
exhaust stack, precleaned, blade, and winch or rip-
per. Figures 2–7 through 2–11 show the removable
items.
2-5. Unusual Characteristics
require special attention be given to temperature,
atmospheric pressure, or humidity variations during
exposure to normal transportation environments.
2-6. Hazardous and Dangerous
Characteristics
The D7 crawler tractors will not present any special
hazardous characteristics during exposure to normal
transportation environments.
NOTE
Those regulations and/or transportation pro-
cedures normally associated with vehicles
This tractor has no unusual characteristics that would
containing diesel fuel will apply.
