Definitions

  • Background Information Brush cutting operations have a variety of purposes. Some major purposes are clearing utility rights-of-way and road sides of obstructing vegetation and thinning trees for land management. In such situations, it is of course desirable to retard the regrowth of cut vegetation and maximize the period of time before the clearing or thinning operation needs to be repeated.
  • One method of retarding regrowth is to spray the cut areas with suitable chemicals. Since cut vegetation, such as tree stumps, tends to heal over most immediately, it is important that any spraying operation be conducted as soon as possible after the cutting. For this reason, it is not unusual for a cutting contractor to be required to spray within ten minutes of cutting.
  • the brush cutting apparatus comprises the combination of a boom having opposite end portions, and a work head pivotally attached to one of the end portions.
  • the work head includes a housing and a cutting blade carried by the housing.
  • the housing includes a protective shroud surrounding a portion of the blade.
  • a spray nozzle is mounted on the housing and is slidable between a nonuse position and a spray position. In the nonuse position, the nozzle is positioned above a portion of the housing. In the spray position, the nozzle projects horizontally outwardly from the housing to permit liquid to be sprayed downwardly from the nozzle onto cut brush.
  • An activator remote from the housing is operatively connected to the nozzle for selectively spraying liquid therefrom.
