Description

Scalpers or fireplows originally designed to build wide, shallow firelines have been adapted for removing existing vegetation competition for interseeding into aggressive perennial or nonnative annual grasses. They create a wide, flat-bottomed trench that serves as a seed bed when incorporated with a seed distribution system.

Application

There are at least two available scalper types: a tractor-mounted 3-point system and a modified D-5 bulldozer (Mad Max). Both have ripper teeth that dig a deep furrow seed bed and broadcasters for surface seeding the exposed soil.

Considerations:

  • Contours of the slope should be carefully followed to minimize erosion.
  • Can operate on slopes of up to 20%.
