ABSTRACT:
A towable earth working apparatus for landscaping, leveling, grading, cutting and for spreading dirt, sand, gravel, is hitched by a trailer arm to a vehicle such as a small tractor or pickup truck. The apparatus has a grader secured to a trailer having a carriage frame with a wheel support assembly attached to a pivot attachment mechanism. The wheel support assembly supports laterally spaced wheels about a journal axis. A wheel support actuator is connected to the journal axis for transmitting actuator movement to the wheel support assembly, where the wheels pivot in both angular directions about the journal axis, to raise and lower the wheels relative to the grader, changing the grader's height. The angular inclination of the grader relative to a reference plane, and consequently the angular inclination of a cutting blade mounted on the grader, is still further adjusted by a pivot attachment actuator, such as a turnbuckle, of the pivot attachment mechanism.
