Straight Dozing
HEAVY DOZING: Tip blade back so skid shoe is flat on the ground. A channel will be formed by losses from side of blade. Move succeeding loads in this channel to reduce spilling. Down shift and/or raise blade slightly if load slows machine.
If blade digs in and raises rear of tractor, raise blade to keep cut even.
LIGHT DOZING: Keep skid shoe flat on ground to prevent blade sucking into ground.
SLOT DOZING: Doze a slot the width of blade, deep enough to prevent material spilling at sides. Use for stockpiling and high production.
A full blade handles easier than partially loaded blade when finishing or leveling.
STOCKPILING: Standard blades as well as special design blades can be used.
Ditching
SHALLOW "V" DITCHES: Tilt blade so low corner will remove enough material to leave smooth path for tires. Repeat passes to obtain desired depth. Spread windrow. Clean existing ditches in the same manner.
Work downhill when possible.
LARGE DITCHES: Establish ditch line. Doze at right angles to center line of ditch. Doze length of ditch to smooth sides and bottom when desired depth is reached.
Side Hill Cut
Tilt blade down on uphill side of cut to form level bench. Cut bench wide enough for machines that will follow. Make starting cut with a series of downhill cuts if necessary.
Tree or Brush Removal
TREES:
- 1. Remove dead limbs. Cut roots on side opposite direction of fall. Cut roots on sides parallel to direction of fall.
- 2. Ease into tree. Push in direction of fall with blade high. Build earth ramp if higher contact is needed.
 |
Back away immediately when tree starts to fall. Do not drive on stump while tree is falling. |
 |
SMALL TREES OR LARGE BRUSH: Make contact 12 to 16 inches (300 to 400 mm) above ground. Move forward while lifting blade.
SMALL BRUSH: Lower blade a few inches into ground and move forward. Lift blade when brush is out to remove earth from roots.
Push Loading
- 1. Position cutting edge slightly above ground level.
- 2. Match travel speed of scraper as near as possible when making contact.
- 3. Contact push block squarely. Keep blade or push cup from contacting scraper tires.
- 4. Tip blade back to transfer scraper weight to tractor, but only enough to help eliminate tire slippage.
- 5. Upshift tractor when cut is complete to help scraper pick up speed.
- 6. When tandem pushing, front tractor must be equipped with case mounted push block.
