be drifted short to medium distances. Blade curvature
lifts the dirt high with a rolling action to lower resistance
and speed drifting. These blades have the side advanced
ahead of the center section and tilt up to 15 degrees, right
ANGLE BLADE. The angle blade (fig. 11-18) is
a multipurpose tool that can be used for general dozing
and for the side casting of materials. The angle blade can
be positioned straight ahead or angled 25 degrees to
either side. The moldboard has a greater curve than a
straight blade to produce more rolling action.
U BLADE. The U blade (fig. 11-19) drifts
large volume loads efficiently over long distances. The
center section lifts material high with a forward roll. The
side sections are angled so they lift and roll materials
inward, keeping the load centered with a minimum loss
of material to the side. This type of blade has the sides
well advanced ahead of the center section, causing a U
shape. It may also be tilted 15 degrees, right or left.
