摘要： A plow blade having a fluid passageway and points of fluid ejection is produced with basic manufacturing processes allowing for efficient production. The blade construction has a multiple component assembly for providing the ability to rebuild a blade and replacing a portion of the blade that may be worn. In another aspect of the invention a process of ejecting a specific fluid at specific points along a plow blade the desirable characteristics are maximized, while the volume of ejected fluid is minimized. This method is adaptable in static plowing and vibratory plowing utilities since lubricating the sides of the blade/chute that come into contact with the ground with fluid has been found to greatly reduce the amount of drag (friction).

摘要： A bearing support arrangement for a grader blade uses short stroke hydraulic cylinders to compensate for wear between slide bearings and slide rails of the grader blade. The cylinders are preferrably pressurized by grease and a grease fitting is provided for each cylinder to provide with convenient access, to allow service by the operator. Preferrably the cylinders are located in a generally closed cavity between the bearing support holder and the slide bearing.
