Crawler Tractor Uses.
ENVIRONMENTAL: During operation, damage caused by erosion due to rain,
must be limited by dressing off the work area at the end of each day. Dust and
exhaust created by equipment also affects the environment, avoid any
unnecessary equipment usage.
NOTE: Show PPt #17
1. Leveling
a. Also known as straight dozing. Leveling is simply cutting high areas and filling the
low areas to create a level surface.
b. If the blade digs in, the rear of the tractor will rise. To keep a level cut, raise the
blade until the tractor is level again.
c. If the blade starts to ride over the material, the front of the tractor raises. To keep a
level cut, lower the blade until the tractor is again level.
NOTE: Show PPt #18
2. Stockpiling
Stockpiling is a basic function of the crawler tractor in which large quantities of
material are pushed into a pile and/or leveled.
NOTE: Show PPt #19
3. Ditching
a. Flat Bottom Ditching (Slot Dozing)
1) Slot dozing is recommended for stockpiling because of its high production output.
27
Slot dozing uses the spillage from the first few passes to hold the material in the slot
for all sequential passes.
2) To increase production output, move the dozer over to either side leaving a
narrow uncut section between slots.
3) Used for large amounts of water drainage.
4) Can be used to hide equipment.
5) Increases work productivity by 20%.
NOTE: Show PPt #20
b. V-Ditching
1) The tilt cylinder on the crawler tractor blade is designed to allow the crawler tractor
to cut shallow v-ditches by tilting the blade, allowing the corner of the blade to
penetrate the ground.
2) The crawler tractor can be used to cut larger ditches by cutting at right angles to
the center line of the ditch.
3) Once the desired depth has been reached, complete the ditch by smoothing the
sides and bottom.
NOTE: Show PPt #21
4. Push loading
a. The crawler tractor can also be used to assist scrapers in loading operations.
b. By centering the reinforced portion of the bull blade on the push block of the
scraper, the crawler tractor can be used to help the scraper load on all types of
material.
NOTE: Show PPt #22
5. Blade to Blade Dozing
a. Also known as "Buddy Dozing", blade to blade dozing is normally used for moving
large amounts of material.
b. By putting both bull blades together, you can increase production output due to the
larger area of excavation.
c. Remove the uncut section by normal dozing, and if the soil conditions are good,
production output can be increased by as much as 15-25%.
NOTE: Show PPt #23
6. Downhill Dozing
a. When using the downhill dozing method, you must push the material all the way to
the bottom of the hill.
b. After several loads are piled at the brink of the hill, push them all to the bottom at
the same time.
c. Use caution when steering on steep down grades. The tractor may respond to the
steering controls differently.
NOTE: Gravity may force the tractor to move forward faster when the track is
disengaged.
NOTE: Show PPt #24
7. Clearing and Grubbing
a. Brush and Small Trees- Travel forward with your blade lowered into the ground
only as far as it takes to cut the brush and tree roots. It may be necessary to back up
28
occasionally to clear the blade of roots.
b. Medium Trees- Raise the blade as high as it will go, ease into the tree in low track
speed and push. As the tree falls over, back up and lower the blade under the exposed
roots. Raise the blade to lift out the trunk and roots of the tree as the dozer travels
forward.
c. Large Trees- First, gently and cautiously probe the tree for dead limbs that could
fall. Determine the tree’s natural direction of lean, if any; this is the best direction for
pushing the tree over. Then, position the blade high and center it on the tree for
maximum leverage. If possible, push the tree over the same as a medium tree.
However, if the tree has a massive, deeply embedded root system, use the following
method:
1) Start on the side opposite the proposed direction of fall, and make a cut deep
enough to sever some of the large roots. Make the cut like a V-ditch, tilted downward
laterally toward the roots.
2) Cut side two.
3) Cut side three.
4) Build an earth ramp on the same side as the original cut to obtain greater pushing
leverage. Then push the tree over and, as the tree starts to fall, reverse the dozer
quickly to avoid the rising root mass. After felling the tree, fill the stump hole so that it
will not collect water.
NOTE: Show PPt #25
8. Berms and Dikes
a. Earth, 20 feet or less in height, should have a crest at least 3 feet wide.
b. Earth more than 20 feet in height, should be at least 5 feet wide at the top.
c. The slope shouldn't be steeper than 2:1 to reduce erosion and ease maintenance.
NOTE: Show PPt #26

1. Blades
A dozer blade consists of a moldboard, (3) cutting edges and (2) end bits. Blades
vary in size and design based on their different earth moving functions. At 1" from
moldboard the cutting edges may be rotated, however the end bits must be replaced.
a. Straight blade
1) Used for cutting ditches and breaking through crusted material. It is mounted in a
fixed position, perpendicular to the line of travel.
NOTE: Bulldozer blade is factory set to a NEUTRAL pitch angle which, under
most circumstances, will provide ample bulldozing capacity. Blade can be
adjusted to provide more or less pitch angle based on bulldozing requirements.
Pitching blade back causes blade to carry more material. Pitching blade forward
causes blade to carry less material. If bulldozer blade pitch angle must be
adjusted, notify Field Maintenance.
2) It can be tilted laterally 13 degrees left or right of center with the use of the
hydraulic controlled tilt cylinder.
3) Reinforced for push loading scrapers.
b. Angle Blade
1) Effectively used to side cast material for back filling or making side hill cuts. It is
also used for rough grading, spreading piles, or windrowing materials.
2) This blade can be set at 90 degrees for normal dozing operations or at angles of
25 degrees left or right for side casting operations.
3) With the angle blade attached to the D7R, the blade cannot be tilted.
NOTE: Show PPt #28
2. Roll over protective structure (ROPS): Protects the operator in the event of an
accidental roll over.
3. Winterized Cab: Protects the operator from severe weather.
WARNING: Never turn or back up with the rippers in the down position.
NOTE: Show PPt #29
4. Ripper
a. For ripping soft material, all three shanks can be used. For medium material the
outer two shanks should be used. For hard material, one shank should be used and it
must be the middle shank.
b. crawler tractors equipped with rippers normally have only three teeth mounted at
the rear. Most ripping operations should be performed in first gear.
NOTE: Show PPt #30
WARNING: Personal injury or death can result from unexpected movement of
30
objects. Be sure all persons are clear of cable and objects before a machine is
winched or moved. A safe distance of at least one and a half times working
length of cable should be maintained. Tail end of a moving object can throw
debris at bystanders.
- When reeling in objects, be sure all personnel are clear of load.
- A minimum of five complete wraps of cable must be maintained on winch
drum. Do not handle a load with a winch drum that has less than five wraps.
- Do not operate winch under loads that exceed maximum rated bare drum line
pull. If excessive loads are encountered, use a multi-part line and sheave blocks.
Any attempt to exceed capacity of one winch is extremely hazardous. Never try
to couple two or more machines together.
- Do not jerk loads and avoid sudden shock to loads. These types of operations
cause heavy loads in excess of winch rated capacity, which in turn may result in
cable failure or winch failure.
- Winch is not designed or intended to be used for lifting or moving persons.
- Do not release winch brake to reel out a suspended load. Use only reel-out
function.
- Wear leather gloves when handling winch cable.
- NEVER attempt to maintain cable tension by allowing cable to slip through
your hands. Use hand-over-hand technique only.
- Keep hands and clothing away from winch drum and rollers.
- Verify ground is stable before winching in a load.
- Failure to follow these warnings may result in death or injury to personnel.
CAUTION: Warm-up procedures are mandatory when ambient temperature is
below 40ºF (4ºC). Failure to follow this caution may result in damage to
equipment.
NOTE: Always attempt to line up rear of machine with load so load can be
winched in a straight path. This avoids unnecessary strain and wear on winch
side rollers, and helps wind cable onto drum in level layers.
- Maintain a sufficient clearance between machine and load to allow machine to
turn.
- Winch is not equipped with free spool function.
- Refer to TB 43-0142 for winch cable inspection procedures.
5. Winch is used for recovery of other equipment or self recovery.
CAUTION: To avoid injury, ensure area is clear of personnel up to 1 1/2 times
the distance of wire rope that is reeled out. Always winch in a direct line and
always wear gloves when working with wire rope.
a. Crawler tractors equipped with winch's can be used for recovery of vehicles,
towing, and holding a load.
1) The winch cannot be used to pull when there is less than five wraps of cable on
the winch drum.
2) Winch speeds are proportional to control lever position. Greater movement of
lever causes winch to operate faster.
3) Keep tow line angle to a minimum. Do not exceed a 30 degree angle from the
31
straight ahead position.

ELO B - LSA 4. Learning Step / Activity ELO B - LSA 4. Construct a Berm.
Method of Instruction: Demonstration
Mode of Delivery: Resident Instruction
Instr Type (I:S Ratio): Civilian - ICH (1:3) (1:3 PE 1)
Time of Instruction: 6 hrs 30 mins (5 hrs 35 mins PE)
Media Type: Actual Equipment / Conference/Demonstration / Student Guide
Other Media: Unassigned
Security Classification: This course/lesson will present information that has a SecurityClassification of: U - Unclassified.
Note : Before starting any work, ensure a digging permit has been issued and
then walk the area to uncover any hazards and plan the job. Check for buried
utilities lines and pipes and always check overhead clearance.
1. Interpret the data on construction stakes.
a. Determine the direction for excavation.
b. Position the crawler tractor.
2. Construct a berm with excavated material.
a. Slowly lower the blade to a depth of 4-6 inches and maintain a smooth cut.
b. Push material being excavated toward the berm keeping the excavation to depth to
between 4-6 inches.
c. When you are one crawler tractor length from the berm start point, begin to raise
the blade slowly allowing the material fall under the blade to start forming a ramp at
approximately a 2:1 ratio.
d. Position the crawler tractor at the start point with approximately 1/3 of the blade
overlapped onto the first pass.
e. Maintain a direction directly toward the original berm.
f. Ensure the area that material is being cut from remains level. DO NOT back blade to
level.
g. Berm the material on each successive cut in the same manner.
h. Construct the berm higher on each pass until it reaches the desired height.
3. Correct excavation irregularities.
NOTE: The slower the engine RPM, the more sluggish your blade control. If you
attempt to cut too deep, you will create a washboard effect consisting of a series
of high areas followed by low areas in the bottom of the ditch.
a. To correct a washboard effect, cut the top of each high spot and fill the low spots.
b. Do not attempt to straighten the excavation in one pass.
c. If bottom of the excavation is not level:
a) Back up to the last level point in the excavation.
b) Make a light cut, cutting just enough to level the bottom of the excavation.
55
d. Do not over correct the blade.
4. Back Fill Material
a. Start the crawler tractor moving forward and lower the blade to desired height.
b. Adjust the blade to the height of the surrounding area and move the crawler tractor
into the side of the berm using approximately 1/3 of the blade to cut.
c. Continue to work to the left side of the berm.
NOTE: Depending on the size of the berm, you should not cut into the berm
straight on. Large berms should be worked from the side, cutting material away
from the berm, using 1/3 of the blade. When moving materials higher than the
midpoint of the ROPS, you must adjust the height of the cut to eliminate the
danger of falling overhangs. On the successive cuts, follow the procedures for
normal spreading operations using the first cut height as a guide for blade
depth.
d. Raise and lower the blade without stalling the dozer or spinning the tracks.
e. Move forward while spreading material and slowly raising the blade until all material
is feathered to match the surrounding area.
f. Place the crawler tractor in reverse after the blade has been emptied.
g. Raise the blade high enough to clear any obstacles and back the crawler tractor
back to the berm.
h. Reposition the crawler tractor for another cut again cutting into the berm using 1/3
of the blade.
i. Repeat steps until the berm has been leveled and spread over the designated area.
j. Restore the area as close as possible to its original state to match the surrounding
area and existing drainage.
Check on Learning:NOTE: Instructors have the latitude to change these
questions and ask questions based on the student
needs.
Q: How deep are the cuts to excavate material to construct
a berm?
A: 6-8 inches.
Q: How much blade overlap is used after the first cut?
A: 1/3 of the blade.

LessonNumber/Title
052-12N10C04 Version 1 © / Operate a Crawler Tractor (CRM)
Security Classification Unclassified
IntroductionThe crawler tractor is a versatile piece of engineer equipment that can be used for multiple
tasks on construction projects. When using the ripper, the crawler tractor can rip hard material
to include large rocks, asphalt and in the next minute be excavating a trench or finishing slopes.
It can also be used to push load scrapers, stockpile materials, winch equipment from mud or
soft material and is also the primary piece of equipment used for clearing and grubbing
operations. Listen close and pay attention and you will learn how to operate the crawler tractor
to successfully perform your mission.
MotivatorExplain the Operational Environment (OE) to include lessons learned throughout this lesson.
Ensure the students are aware of how it will affect them during their future assignments. For the
most current information visit the CALL web site at HTTP://call.army.mil. Review all material to
be used from CALL site to prevent release of sensitive information.
Note: Relate instruction to current world countries where they could be deployed.
- Explain how the eight interrelated operational variables: political, military, economic,
social, information, infrastructure, physical environment, and time could apply to your
role as an operator.
LearningStep/Activity NOTE. The instructor should inform the students of the following Learning Step/Activity requirements (ELO C - LSA
3). At the completion of this lesson, you [the student] will:
Action: Excavate Material.
SafetyRequirements In a training environment, leaders must perform a risk assessment in accordance with ATP 5-
19, Risk Management. Leaders will complete the current Deliberate Risk Assessment
Worksheet in accordance with the TRADOC Safety Officer during the planning and completion
of each task and sub-task by assessing mission, enemy, terrain and weather, troops and
support available-time available and civil considerations, (METT-TC). Note: During MOPP
training, leaders must ensure personnel are monitored for potential heat injury. Local policies
and procedures must be followed during times of increased heat category in order to avoid heat
related injury. Consider the MOPP work/rest cycles and water replacement guidelines IAW FM
3-11.4, Multiservice Tactics, Techniques, and Procedures for Nuclear, Biological, and Chemical
(NBC) Protection, FM 3-11.5, Multiservice Tactics, Techniques, and Procedures for Chemical,
Biological, Radiological, and Nuclear Decontamination. Review local training area SOP. Know
and adhere to all hand and arm signals. Perform an equipment walk-around before and after
operation. Maintain three points of contact when mounting and dismounting. Wear goggles and
gloves when checking batteries, hydraulic tank, and fueling the equipment. Wear hearing
C-15
protection, kevlar / hard hats, safety boots and seat belts when operating or around running
equipment. Do not wear loose clothing or jewelry. Utilize drip pans and always look in the
direction of travel. Use caution when working on hills, banks, or steep slopes to avoid tipping.
DO NOT place transmission in neutral to allow the equipment to coast.
Risk AssessmentLevel
Low
EnvironmentalConsiderations NOTE: Instructor should conduct a risk assessment to include environmental considerations
IAW the current environmental considerations publication, and ensure students are briefed on
hazards and control measures.
Instructors must complete a risk assessment before conducting training, operations, or C-1
logistical activities. Abide with all applicable laws and regulations.
Based on its commitment to environmental protection, the Army will conduct its operations in
ways that minimize environmental impacts.
• Comply with all environmental laws and regulations. This includes federal, state, local, and
Host Nation laws.
• Prevent pollution at the source by reducing, reusing, and recycling material that causes
pollution.
• Conserve and preserve natural and cultural resources so that they will be available for present
and future generations.
• Ensure drip pans and spill kits are on hand to prevent / mitigate any Petroleum, Oil, and
Lubricant (POL) spills.
• During refueling operations ensure fuel nozzle is properly in the fuel tank, operator has
physical control of the fuel nozzle/handle and is trained on reacting to a fuel or POL spill.
Units and installations will prepare an environmental risk assessment using the before, during,
and after checklist. The checklist should supplement local and state environmental regulations
applicable to your area.
EvaluationThis test evaluates the service member’s ability to safely and effectively excavate with a crawler
tractor in accordance with the technical manual. The evaluator will observe the service
member’s performance of excavating with a crawler tractor. The service member shall not ask
for or be given any assistance from the evaluator or other service member. The service
member’s performance shall be measured as a GO/NO GO score. If a NO GO is received on
any portion of this test, the service member shall receive a written counseling and remedial
training for a minimum of one hour before being re-evaluated. The evaluator shall also observe
the service member for any safety violations which could potentially cause death/injury to
