Angle Dozers work best handling broken and granular materials,
soils and gravel. The moldboard pivots about it's center
point to cast materials left or right. Ideal for making
windrows, digging drainage ditches, backfilling trenches
grading roads. This is a good all purpose blade,
especially when equipped with Tilt Cylinders.

Straight Blades can be made very strong,
abrasion resistant and puncture resistant for moving
large, sharp and abrasive objects. They are not well
suited to handling granular materials since these
materials spill off the ends during long pushes.
Straight Dozers are able to
Tilt when equipped with
one Tilt Cylinder and Tilt and Tip when equipped with
two. |

Built much like a Straight Blade but with
a deeper profile and closed ends to help keep granular
materials in front for long pushes. Semi-U Blades can be
built with good abrasion resistance for materials like
gravel, and with puncture resistance for handling large
angular pieces of rock.
Semi-U Blades are able to Tilt when equipped with
one Tilt Cylinder and Tilt and Tip when equipped with
two. |

These blades are designed to push large
quantities of granular materials over long distances.
They are best suited for loose loads; coal, woodchips,
and overburden, which are evenly distributed across the
face of the moldboard. They are not well suited to
handling large angular objects such as blast rock.
U-Blades are able to Tilt when equipped with
one Tilt Cylinder and Tilt and Tip when equipped with

Cushion Dozers are
not available as a moldboard only. They are always part
of a special dozer group which is made predominantly for
pushing other Dozers and Self Loading Scrapers when more
tractive effort is required.
The dozer moldboard
is hinge mounted to a special inside push beam. Resilient
pads or some other form of cushioning material absorbs
shock loads when the blade comes in contact with the
tractor to be pushed.
