Configuration changes to cutting edge should NEVER be attempted without first securing the bowl by
blocking it so that it is firmly supported. Failure to follow this warning may cause injury.
Cutting Edge Configuration Changes.
Determine most efficient configuration of scraper bowl cutting edge for material to be loaded and degree of grading
(1) Straight Edge. This is most suitable for finishing work or where shallower cuts are required.
(2) Stinger Edge. This configuration will reduce work cycle time by allowing for a more aggressive material bite.
Working with a stinger edge is recommended only for the more experienced operator.
In general, the higher the penetration capability of cutting edge, the coarser the material that will be lifted into the
Notify Unit Maintenance to convert cutting edge to suitable configuration, in accordance with procedures in TM 5-
During construction of a horizontal surface, material removed will be used in an area that must be subse-
quently compacted to provide a hard, smooth base. Properly adjusted, the material deposited will be readily
compacted with a minimum of additional time and effort.
Prior to loading, the operator needs to know the disposition of the material removed during the cut, because this
affects how the machine is loaded and the adjustments the operator needs to make:
(1) If material removed is to be used to create a base for a horizontal surface, loading must be accomplished to pro-
duce an engineered material suitable for subsequent compaction.
(2) If material removed is to be stockpiled, the goal will be to load and dump as quickly as possible.
The scraper is most effective when there is a moderate "blade load." With little load, the machine is not working to
The operator can make numerous adjustments during loading and unloading to optimize performance. These adjust-
ments control depth of cut, amount of bulldozing in front of blade during loading, and depth of spread during unload-
