The floating position system consists of a hydraulic accumulator controlled by an electric valve. A test of the floating position function of the boom mower is carried out as follows:
1. Lower the arm of the boom mower and attachment tool to the ground using the joystick in the cabin, so that the boom mower is relieved 100% on the ground surface.
2. Hydraulic float of arm is activated using the button on the control panel (Green LED lights up) (Accumulator is now 100% depressurized).
3. Hydraulic float of arm is de-activated again using the button on the control panel (Green LED turned off).
4. Raise the arm of the boom mower at approx. ½ meter height using the joystick in the cabin.
5. Hydraulic float of arm is activated once again using the button on the control panel (Green LED lights up).
6. The arm of the boom mower must now visibly lower approx. 10-15 cm and you will be able to feel a smaller “spring-like” effect in the arm (If the attachment tool does not lower, contact the GreenTec dealer).
