Towed Earth Moving Implement with Fixed-Winged Pitch-Adjustable Blade Assembly
A towed earth moving implement features a longitudinal pull tongue, a winged blade assembly with a transverse center blade and a pair of angled outer wing blades, and a wheeled frame on which the blade assembly is carried. A pivotal blade-pitch between the pull tongue and the blade assembly defines a transverse blade pitch axis about which the blade is adjustable in pitch-angle relative to the pull tongue. In a pitch-neutral position, working edges of the wing blades reside in a same horizontal working plane as a working edge of the center blade, for ground leveling purposes. In an upwardly pitched position, the working edges of the wing blades reside in forwardly inclined relation to the horizontal working plane, for ditching purposes. In a downwardly-pitched position, the working edges of the wing blades reside in forwardly declined relation to the horizontal reference plane, for crowning purposes.
