发明名称 Blade pitch indicator
摘要 A blade pitch indicator is releasably secured to a linear actuator in the form of a turnbuckle. The blade pitch indicator comprises a cover having protrusions forming arrow points that line up with a line of demarcation on the linear actuator. Indicia is associated with the protrusions to provide blade pitch positioning information to the operator. The turnbuckle is provided with two moveable yokes and a stationary threaded shaft. The threaded shaft is rotated to extend and retract the yokes, thereby adjusting the pitch position of the bulldozer blade. The threaded shaft is provided with a multifaceted nut in the form of a hexagonal nut that is engaged by a wrench to rotate the threaded shaft. The hexagonal nut is provided with an aperture through which a pin is inserted releasably securing the cover to the turnbuckle. The arrow points of the protrusions line up with the base end of the yokes to indicate the bulldozer blade's pitch position.
