Dozing
Straight Dozing: If the blade digs in and the rear of the machine rises, raise the blade to continue even cut. When moving a heavy load causes travel speed to drop, shift to a lower speed and/or raise the blade slightly.When doing finishing or leveling work, a full blade handles easier than a partially loaded blade. Slot Dozing: This allows larger loads to be carried in front of the blade. It is used in stockpiling and high production bulldozing. Side-by-Side Dozing: Use when moving large quantities of loose material. Keep the blades close together and the machines parallel. Tilt Dozer Ditching: Tilt the blade and work with the low side in the ditch center. Level the blade when the required depth and slope are reached. Straight Dozer Ditching: Tilt the blade to cut shallow "V" ditches. For larger ditches, doze at right angles to the center line of the ditch. When the desired depth is reached, doze the length of ditch to smooth the sides and bottom. Angle Dozer Backfilling: Travel parallel to the ditch. Angle blade to backfill the material. Straight Dozer Backfilling: Push at a 90° angle to ditch.Land Clearing
Typical Artwork
1. Remove all dead limbs. Cut roots on side opposite direction of fall.2. Cut roots on sides parallel to direction of fall.3. Ease into the tree. Push in direction of fall with blade high. Build a earth ramp if higher contact is needed.4. Do not drive onto stump while tree is falling.
Back away immediately when tree starts to fall, to prevent possible injury.
Large Brush and Medium Size Trees: Contact the tree 300 to 400 mm (12 to 16 inches) above the ground. Move forward while lifting the blade. Brush Clearing: Lower the blade slightly into the ground and move forward. Lift the blade when the brush is out, to loosen the earth from the roots. Stump Removal: Lift the blade while pushing.Ripping
Use FIRST speed for most ripping operations. It is better to use additional shanks, where practical, rather than to increase speed.Always use center shank when ripping with one shank. If material breaks up satisfactorily, more shanks may be used.Cross rip only when necessary.When ripping for scraper loading, rip in same direction that scrapers will load.Rip downhill whenever possible.
Do not turn or back the machine while shanks are in the ground. Twisting strain on the shanks and tips may cause failure. Inspect the ripper tips frequently for excessive wear.
Ripper Operating Hints
In most cases it is desirable to rip as deep as possible. Sometimes it is better to rip at partial depth and remove the material in its natural layers.Keep material on top of the unripped formation to cushion the machine and provide traction.When final material size must be relatively small, close spacing of passes is recommended.Packed Soil, Hard Pan, Clay, Shale or Cemented Gravel
Three shanks work well in these materials. Use as many shanks as possible to break material to desired size, without stalling or hanging up the machine.Rock with Fractures, Faults and Planes of Weakness
