Pre-Harvest Intra-Row Vegetation Management In Brazil

Intra-Row Mowing

In Brazil, it is common for a Eucalyptus forest to be planted over a Pine forest, which can result in volunteer pine trees as a major problem, specifically between the rows. If there are too many Pine trees in a load, mills can reject the harvested Eucalyptus trees.

Removing these unwanted Pine trees, as well as other vegetation between the rows of planted Eucalyptus trees, requires a mechanical solution. Diamond offers a Skid-Steer Forestry Mulcher that can effectively remove large vegetation using a Compact Track Loader (CTL) that is small enough to fit between the rows.

By using this solution, it will provide the following benefits:

  • It is affordable
  • It can increase harvesting speed by as much as 30%
  • It prevents expensive harvest equipment from having to remove Pine trees
  • The removal of the unwanted Pine trees prevents rejected loads at the mill


When harvest is complete, stumps can slow down skidding operations and make re-planting more difficult. Stumps are generally removed in two ways:

  • V-Shear mounted to a bulldozer – this is very expensive, has high fuel consumption, and leaves large debris between the rows
  • Drum Mulcher mounted to an excavator – this is very expensive and has high fuel consumption. The equipment is often too large to work between rows if used for any pre-harvesting operations.

Diamond’s Skid-Steer Forestry Mulcher is a great alternative to these options. This solution slices the stump off, using the hydraulic energy much more efficiently than a drum mulcher.

Additional benefits include:

  • It can increase productivity by almost 50% over excavator-mounted drum mulchers
  • The sharp steel teeth the Skid-Steer Forestry Mulcher contains cuts the material very efficiently

The time between stumps allows the disc to speed up, fully utilizing the energy output of the CTL
