Angle bulldozers are excellent for widening fills, backfilling ditches, or windrowing material in one direction and maintaining forward motion at the same time.Dozer Blade Pitch for the U-Blade and SU-Blade
Illustration 3 g00522784
(1) Extended (2) Retracted (3) NeutralThe NEUTRAL position works well in most materials and applications. The NEUTRAL position provides equal blade tilt to the right and to the left.The EXTENDED position pitches the blade forward. This improves blade penetration in materials that are difficult to penetrate and makes for faster loading.The RETRACTED position pitches the blade backward. The backward pitch enhances the amount of dozer carry.Refer to Machine Adjustments in the Operating Section of this manual.Straight Dozing
Illustration 4 g00040620
Straight Dozing - Maintain a level cut for the best performance. Fill the bulldozer blade. Carry the load to the dump.
Avoid lugging or stalling the machine.
Avoid excessive spinning of the track.
If turning the machine with a loaded blade is necessary, use the bulldozer tilt cylinders instead of the steering lever in order to steer the machine.When you are performing levelling work, a full bulldozer blade manages better than a partially loaded bulldozer blade.Slot Dozing
Illustration 5 g00040626
Slot Dozing - When you trap material in a slot, you can carry larger loads in front of the bulldozer blade.The depth of the slot should not be deeper than the top corner of the bulldozer blade.
Illustration 6 g00040622
Start the slot at the dump or the spoil end and work rearward. See Figure (A) in Illustration 6. You can load the blade as you are moving downhill. Also, you can then carry the load on a level surface. The technique that is shown in Figure (B) is not as efficient as the technique that is shown in Figure (A). In figure (B), the machine is pushing a load uphill and the operator does not utilize the slot. Dozing level through the entire pit is inefficient because the average distance for pushing the material to the dump will be greater.
Illustration 7 g00040628
When you are digging parallel slots, the center should be removed from the rear. This procedure permits the operator to maintain a slot until the center is removed. The center berm should be wide enough to stand up without collapsing. Maximum width should be approximately 1/3 of the bulldozer blade.Machine on a Slope
Machine on a Side Slope
Illustration 8 g00040630
When possible, work on a slope vertically. This method is better than working horizontally.When you are working on banks, use caution. When you are working on slopes, use caution. Avoid tipping the machine.If the machine starts to sideslip on a slope, lighten the load and turn the machine downhill.If you are working horizontally on a slope, start at the top of the slope. Work downhill. Maintain a windrow of material on the low side of the machine in order to provide stability.Use caution in order to not undercut the slope. Undercutting the slope will increase the slope.Machine on an Up Slope or Down Slope
