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.

Instructional Lead-in The 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.

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.

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 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…
