OPERATING TECHNIQUES
When clearing a rocky area, remove the small and loose rocks first, large and solid rocks can then
be loosened and moved with less difficulty. When loosening large or solid rocks, greater force and
penetration can be obtained by tilting the blade and prying under the rock with the lower edge of
the blade (Fig. 4.40). Lifting the rock with the blade while pushing will increase traction and reduce
track spinning.
Fig. 4.40. Loosening Rocks with Lower Edge of the Blade
Penetration on hard, frozen or rocky ground can be made easier by tilting the blade. This will add
weight and power to the lower cutting edge. When the ground is frozen and the area must be
ripped before it can be worked, rip a relatively small section and work it to grade before enlarging
the cut. This will require ripping each section only once, not every morning after the ground has
refrozen. Snow can act as an insulating blanket and reduce or eliminate the need for a ripper.
Therefore, remove snow only from the area to be worked each day; leave the rest to insulate the
ground.
4.18.2. TRANSPORTING, PILING OR LOADING
The transporting of material with a bulldozer is not always a most economical method. Natural
ridges, a window formed by side blade spillage on earlier passes or side-by-side, dozing will
improve the productivity (Fig 4.41). Where the quantity of material or distance involved becomes
excessive, a loader, scraper or truck should be considered.
