It’s possible to invert spin direction of rotor: this makes the machinery suitable both to cut grass, shrubs (clockwise spin) and operate close to water along rivers (anticlockwise spin). To prevent any accidental inversion, the lever for this function has a safety block.
Floating head allows user to follow uneven ground contours without acting on motion control. A safety system limits maximum head oscillation so, in case of sudden level drop, risk of head falling or tractor overturning are prevented.
Head of hedge cutters permits maximum working flexibility thanks to its rotation angle of 246°. Spiral disposition of blades guarantees a smooth mulching action with very low vibration.
Cast iron made gear pump is more resistant to high temperatures comparing to aluminum: this technical choice is suited to professional use under intense and stressing work conditions.
Hydraulic circuit can be blocked by shut-off valves: this allows user to perform safely maintenance operations, without any dangerous accidental movement of the arm.
The particular conformation of the arm gives to the user optimal sight on cutting head, great control and the best operating comfort. With this arm, cutting head can work on side, close to tractor wheel, or behind it: machine is therefore adapt to work in very narrow street.
This device splits power from PTO on two independent shafts moving pumps for rotor and hydraulic circuit. This solution makes possible use hedge cutter even in heavier condition with maximum reliability.
In case of sudden rotor arrest, a safety valve drops pressure from hydraulic engine to prevent any damage.
A double safety system is active when the arm encounters any obstacle. First protection is a nitrogen dampener working with a hydro-pneumatic circuit. If first system is not sufficient a max safety valve, acting on a cylinder, turns back 90° the arm.
All hinges have pins made of hardened, heat-treated steel; bushings are wear resistant and provided of lubricating nipples.
