Abstract
An improved trimmer type road construction apparatus, particularly useful in applications requiring a high degree of maneuverability and control flexibility, which is steeringly controlled by turning a centrally disposed front track assembly in such a manner that the main frame can be raised and lowered relative to the front drive assembly without a loss of steering control; and which has an automatic steering, grade and slope control constructed to be automatically adapted to particular job specifications and locations. The trimmer also has a reclaimer assembly for removal of the excavated earth, the reclaimer assembly being automatically positionable to deposit the excavated earth in predetermined, controlled positions about the trimmer.
