660 HY WS PowerSafe®
Motor mower with hydrostatic transmission (CVT), steering clutches and PowerSafe® hydraulic clutch.
660 HY WS PowerSafe® is a super-professional hydrostatic motor mower intended for farmers and garden caretakers for intensive use on large areas and steep slopes.
The hydraulically-operated steering clutch-brake units, independent on both wheels, guarantee manoeuvrability and complete control of the machine even in the most difficult conditions.
It is designed for haymaking and forage mowing in the mountains and on steep slopes in general, for clearing uncultivated areas, for greens maintenance and for all activities related to municipalities.
HY | Continuously variable transmission
Thanks to the continuously variable transmission, the operator can continuously vary the speed and direction of the machine using the EasyRider motorcycle rotating knob on the handlebar.
This means an unlimited amount of gears are available for all operating needs.
Specific technical features such as cascade reduction units of gears in oil bath and steering clutches with combined brake control (‘WS’) facilitate manoeuvrability and increase adherence even in the steepest conditions.
