Yes,we have a stump grinder, but non competitive with Rotor.
Vermeer or Rayco used only for park and garden but not in plantation.
In plantation customer used Rotor and big plow with 80 centimeter depth,or Rotor and mulcher with fix teeth like FAE or Seppi M.
The destumper production in poplar plantation (stump diameter 40-60 centimeter and 1 meter depth) is about 600-800 stump a day,8 hour, with 150-200 HP.

Guys, the stumps are harvested, the wood is dense and stronger than normal so what was waste or left in the ground is now a resource and makes profit.
