12. OPERATION 12.10 WORK POSSIBLE USING BULLDOZER In addition to the following, it is possible to further increase the range of applications by using various attachments. 12.10.1 DOZING A bulldozer digs and transports dirt in a forward direction. Slope excavation can always be most effectively carried out by proceeding from the top downward. With the dual tiltdozer, the angle of the blade cutting edge can be changed, so the angle of the cutting edge can be adjusted during the digging operation to improve the efficiency of the work. 12.10.2 CUTTING INTO HARD OR FROZEN GROUND OR DITCHING For digging and ditch excavation of hard or frozen ground, tilt the blade.
Even hard ground can be dug effectively by a tilted or angled blade. If the ground is harder, use a ripper attachment for better efficiency. 12.10.3 FELLING TREES, REMOVING STUMPS NOTICE Do not up root trees or stumps or fell trees by angling or tilting the blade. For trees with a diameter of 10 – 30 cm (3.9 – 11.8 in), raise the blade high and push 2 or 3 times to fell the tree. Next, travel in reverse, and dig the corner of the blade into the ground to cut and dig up the roots. When doing this, never hit the tree at high speed or apply shock to fell the tree. 12.10.4 PUSHER OPERATIONS When carrying out pusher operations, always install a pusher plate.
When approaching the other machine, depress the decelerator pedal to reduce the engine speed and approach slowly. After coming into contact, raise the travel speed slowly and push with full power. 2-63
