point the tube terminates in this manner the volume of fluid at this point can be maximized in addition to varying the length of tube 140 the number of leading edge sections 120 that are welded onto blade 110 can be varied to match the requirements of a specific job including specific installation depths the number of and location of the stitch welds can also be adjusted to tailor a plow 100 for a specific application in this manner it is possible to provide a nearly infinite variety of configurations in an economic manner another embodiment is illustrated in fig9 and 10 in this configuration a manifold 160 is installed in between the blade 110 and the leading edge sections 120 the manifold includes drilled holes 166 extending from a front side 164 to a rear side 162 as illustrated in fig1 the drilled holes 166 intersect at the middle and when the leading edges 120 are installed onto the front side 164 the drilled holes 166 will terminate at the void 124 in the leading edge 120 in this manner a flow path is defined by the void 124 and the holes 166 which will allow fluid to be routed from tube.
