Quadsaw LRS 4002 & 4802
- Perfect cutting quality, both thick and thin branches
- Forward speed = very high capacity
- Power Drive transmission, high efficiency, low power requirements
- Saw blades with carbide tipped teeth = long life and minimal maintenance (grinding)
The world's largest saw for excavator
GreenTec presents the world's largest saw with working width of either 4.0 or 4.8 m. The saw can be used for cutting branches and hedges in municipal areas or maintaining hedgerows in the agricultural areas. The saw can be mounted on larger backhoe loaders and excavators. It goes without saying that the capacity is huge.

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.
