31. EFFECTIVE METHOD OF OPERATION FOR DUAL TILT DOZER 31.3 LEVELING (SPREADING) OPERATIONS Carry out this operation with R pitch. When carry out this operation with R pitch, the end bit does not dig in, and the ground can be leveled (or the soil can be spread) smoothly. REMARK If the tilt cylinder is moved completely to the end of its stroke, the tilt operation cannot be carried out on one side, so move the cylinder back slightly from the end of its stroke to the S pitch position. 31.4 DITCHING OPERATIONS If the dual tilt is used, the digging width becomes smaller and a deeper ditch can be dug. If R pitch is used, the digging can be carried out gradually, and this reduces the unevenness.
31.5 BOULDER RAISING OPERATIONS Because the dual tilt greatly increases the amount of tilt, the blade can dig in deep and hook under the boulder. In addition, the operating stroke is large, so operations to raise boulders can be carried out effectively. 31.6 SIDE-CUTTING OPERATIONS Carry out this operation in R pitch, and set the end face of the end bit in contact with the rock face to carry out cutting. REMARK With the dual tilt it is possible to increase the amount of tilt and to carry out side-cutting operations on higher walls. 5-12
