ABSTRACT:
The vegetation control material applicator comprises a toroidal reservoir for containing a nominal amount of vegetation control material in fluid form and a circular valve assembly mounted between the reservoir and the circular saw blade of a brush saw. The reservoir and the valve assembly are mountable on the arbour of the brush saw with the valve assembly being in contact with the underside surface of the saw blade. The reservoir and valve assembly each have a diameter which is substantially less than the diameter of the saw blade. The reservoir has an opened side which is in communication with the valve assembly. The valve assembly comprises a valve disc and a valve seat. The valve disc is made of a material having the ability to resonate and to sustain a vibration therein. The valve seat is made of a material having vibration dampening properties. Therefore when an impulse is imparted by the saw blade to the valve assembly, a distortion of the valve disc relative to the valve seat causes the valve assembly to release a slight amount of vegetation control material on the underside surface of the saw blade. In another aspect of the present invention, the valve assembly comprises a set of spacers between the valve disc and the valve seat. The spacers are made of absorbent material and have a total thickness related to the viscosity index of the vegetation control material within the reservoir of the applicator.
