CAUTION: When operating on severe slopes, maintain engine oil level to FULL

mark. Engine should never be overfilled with oil. Damage to engine may result.

1. The D7R dozer is the primary piece of equipment used for most earth moving

operations. It features:

a. Excellent maneuverability

b. Fast, precise blade control without drift

c. Superior visibility, convenience, and safety

d. Advanced cab design featuring joysticks for control

2. Crawler tractors with the ripper attachment are designed for dozing, ripping soil,

rocks, asphalt, concrete, and can penetrate and rip compacted soil embedded with

boulders.

3. Crawler tractors with the winch attachments are designed for dozing and pulling or

25

lifting loads.

4. Crawler tractors are capable of operating in all types of weather and terrain

primarily due to their low ground bearing pressure;

a. Type 1 (winch) 12.4 psi

b. Type 2 (ripper) 13.0 psi

CAUTION: Do not ford even the narrowest stream more than 30 in. (76 cm deep.

Failure to follow this caution may result in damage to machine.

NOTE: Fording speed should not exceed 3-4 mph (5-6 km/h). Once in the water,

do not stop until the opposite bank is reached.

5. Crawler tractors are capable of fording water at depths up to 30 inches deep.

CAUTION: 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 crawler tractor has fast, precise blade control without drift; superior

visibility, convenience, and safety; and an advanced cab design featuring

joysticks for control.

6. The crawler tractor is capable of operating on an incline and decline of 60 percent

(28 degrees).

7. When equipped with a reinforced blade, the crawler tractor is capable of assisting

scrapers in push loading operations.

NOTE: Show PPt #14

8. Limitations.

1. Crawler tractors are very slow moving: (6.55 mph forward / 8.44 mph reverse).

2. Crawler tractors must be transported long distances due to their slow speed,

weight, and wear on tracks.

3. Operating range for the D7R is 50-300 feet.

ELO A - LSA 3. Learning Step / Activity ELO A - LSA 3. Identify Crawler Tractor Uses








NOTE: Show PPt #16

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 #27

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.








Note : Before starting any work, ensure a digging permit has been issued and



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.

1. Determine the stockpile location.

a. Position off the job site.

b. Position downhill if possible.

c. Construct the stockpile ramp at a 2:1 slope ratio.

2. Lower the blade to strip material.

a. Slowly lower the blade to a depth of 6" to 8" and maintain a smooth cut.

b. On the first pass excavate material from a designated start point to a stockpile area

approximately 75' away.

c. Back the crawler tractor back to the beginning of the excavation site.

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 stockpile. Do not build a berm.

f. Ensure the area that material is being cut from remains level. DO NOT back blade to

level.

g. Make successive cuts the same as in step 2 above.

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 ditch in one pass.

c. If bottom of ditch is not level:

1) Back up to the last level point in the ditch.

2) Make a light cut, cutting just enough to level the ditch bottom.

d. Do not over correct the blade.

4. Construct a flat bottom ditch.

a. Position the crawler tractor in as level a position as possible.

b. Lower blade approximately 1/2 foot off the ground.

c. Adjust blade until it is level.

d. Place crawler tractor in motion.

e. Lower blade gradually to make approximately a 6" to 8" deep marking cut.

f. Maintain a uniform cut for approximately 75'.

g. Gradually raise blade to construct an exit ramp that is no steeper than

g. Remove excess material from shoulders.

h. Level remaining windrows.

i. Adjust the blade to remove excess material in ditch.

j. Move excess material away from the ditch.

k. Correct a washboard surface.

l. Correct an unlevel ditch bottom.

m. Continue excavation until the ditch reaches desired ditch stake specifications.

6. Stockpile Material

a. Push material being excavated toward the stockpile keeping the excavation to

depth to between 6-8 inches.

b. When you are one crawler tractor length from the stockpile start point, begin to

raise the blade slowly allowing the material fall under the blade forming a ramp at

approximately a 2:1 ratio.

c. Stockpile the material on each successive cut in the same manner.

d. Construct the stockpile higher on each pass until it reaches the desired height.

7. Back Fill Material

a. Start the crawler tractor moving forward and lower the blade to desired height.

into the side of the pile using approximately 1/3 of the blade to cut.

c. Continue to work to the left side of the stockpile.

NOTE: Depending on the size of the pile, you should not cut into the pile

straight on. Large piles should be worked from the side, cutting material away

from the stockpile, 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

64

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 all the way and back the crawler tractor to the stockpile.

h. Reposition the crawler tractor for another cut again cutting into the stockpile using

1/3 of the blade.

i. Repeat steps until the stockpile 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.

8. Spread a Stockpile.

CAUTION: When spreading materials that are higher than the midpoint on the

rollover protection system (ROPS), adjust the height of the cut to eliminate the

danger of falling overhangs.

1. Position the crawler tractor on the backside of the stockpile.

2. Adjust blade to spread a stockpile.

a. Cut small piles using the full blade.

b. Cut large piles from the side using 1/3 of the blade.
