Hydraulic Brush Cutter for Excavator and Tractor
GreenTec Rotary Crusher GT 135 & 155 is a series of hydraulic brush cutters specifically designed for use in extreme conditions where there are large stumps, rocks or the like. It comes with two blade systems, chains or knives. The chains are used for mowing grass and bushes in stony conditions. The blades are used for hedge cutting and grass mowing in normal conditions. Both systems are very robust.
The brush cutters can be mounted on boom mowers for tractors or excavator arms.

Cavitation and anti-cavitation:
This product comes with an anti-cavitation valve which is used to minimize the risk of cavitation damage in connection with insufficient inlet pressure.
What is cavitation damage?
Cavitation occurs when the pressure drops below the vapor pressure, which will bring the fluid to boil as the boiling point is reduced. Liquid is converted to gas and then the temperature drops and the gas is converted back into compressed liquid again. If the pressure cannot be adjusted continuously, the above process wherein the liquid is converted to gas and back again will be repeated. In the process where gas is converted back into compressed fluid, small implosions that form heat and noise strong enough to erode metal will occur.
