  • a blade 19 is arranged fowardly of the vehicle and is integrally mounted on the forward ends of a pair of transversely spaced push arms, one of which is shown at 21.
  • Each push arm has its rearward end pivotally connected at 22 to mounting bracket 10. It should be noted that the vehicle utilizes a pair of the mounting brackets of the present invention. with each bracket being associated with a respective side of the vehicle.
  • Push arms 21 are raised and lowered by a pair of hydraulic cylinders, one of which is shown at 23, vertically aligned with and disposed above its associated push arm to adjust the elevational position of blade 19.
  • the hydraulic cylinder is pivotally connected to mounting bracket IOand-to blade 19 by pivot pins 24 and 26, respectively.
  • each mounting bracket 10 is rigidly secured as by welding or the like to its associated box member 13 of support frame 12 forwardly of axle 14.
  • the bracket is constructed in the form of a box-like structure which is fabricated from a plurality of'plates fastened as by welding or the like into an integral housing 27 having a hollow chamber 28 defined therein.
  • the bracket has a bifurcated projection 29 which extends forwardly from the upper forward corner of the bracket.
  • a pin 31 or first means forming a pivotal connection extends through the projection to receive pivot pin 24 of hydraulic cylinder 23.
  • a projection 32 extends downwardly from the bottom of the bracket and has pin 22 of a respective push-arm 21 rigidly secured thereto.
  • Each bracket 10 includes a lower inner side plate 33 which abuts box member '13 and has a pair of apertures 34 (FIG. 4) extending therethrough in alignment with pipes 16 and 17 to permit the pipes to extend into chamber 28 of housing 27.
  • An upper inner side plate 36 has its lower edge joined to the upper edge of plate 33.
  • An outer cover plate 37 having a lower portion forming a lower wall 38, is spaced outwardly from plates 33 and 36.
  • the lower wall is angled downwardly and rearwardly at a compound angle and terminates at a lower rear edge 39 (FIG. 4).
  • a rear wall 41 is disposed between the inner plates and the outer cover plate and has a lower edge 42 which is spaced above lower rear edge 39 and cooperates therewith to provide second means forming a material discharge opening 43 therebetween, adjacent to apertures 34 and substantially below and rearwardly of pivotal connection 31.
  • the rear wall has a continuous, forwardly extending portion forming an upper wall 44 which includes a downwardly extending arcuate portion 46 having a lower edge 47.
  • a forward wall 48 has an upper edge 49 spaced below edge 47 to provide third means forming an opening 50 therebetween, adjacent to and below projection 29 and diametrically opposed to opening 43.
