The Loglogic Wetland Harvester is a purpose built low ground pressure machine for the restoration and harvesting of all types of vegetation on wetland habitats where its extremely low ground pressure and unique flexible rubber track ensures minimal damage to both flora and fauna in these environmentally sensitive areas. The cutting head is a rubber mounted double reciprocating knife system with overload protection and an automotive traction stop for the occasional incidence of tree stumps etc. The fully floating suspended head is on large skids with variable ground pressure. This enables it to both roll, and follow ground contours and harvest on the most difficult of terrain.

The well proven, precision chopping system is capable of reducing the harvested material to 10-40mm mean length using an efficient, high speed cutting rotor with 18 tungsten carbide tipped blades. Due to its unique construction, the cutting rotor is relatively insensitive to foreign objects such as stones. The blades can be easily sharpened with the built in sharpening system.

The chopped material is blown into the high tip sealed bulk bin complete with automatic door. It can then be discharged into a reception vessel.

  • Hydrostatic drive system with infinitely variable speed control and single joystick control.
  • Cutting head with double reciprocating knife system with stall detect.
