Conventional weeding system avoids herbicides and facilitates the manufacture of two models of ecological machines. The TRB-SFN Hammer Mulching model and the DDHR-350 Storm Knife Brushcutter model with a double side disc that allows the grass to be cleared and thrown onto the tree trunk.
The TRB-SFN Mulching system has an auger that moves the cut grass towards the tree trunk, covering it, thus preventing the remaining grass from producing photosynthesis by the effect of the sun and drying under the grass cover thrown by the machine. The working niches of the TRB-SFN Mulching model are from 1.80m to 2.20m. Working and tractor power from 60hp to 100hp. As for the Storm model, the DDHR-350 model allows to work in minimum widths of 2.20m and maximum widths of 3.70m.
