For those who need to work in “no-limits” conditions and on steep slopes, BCS introduces the super-professional 660 HY WS PowerSafe® motor mower with hydrostatic drive and assisted hydraulically controlled steering system.

The 660 HY WS PowerSafe® is the only hydrostatic motor mower in the world to be equipped with a patented PowerSafe® hydraulic clutchwith multiple steel discs in oil bath and connected directly to the engine.

The ergonomics of the easily operated levers together with the high drive and braking capability ensure easymanoeuvrability and a total and safe control of the unit, even in the toughest conditions.

The BCS 660 HY WS PowerSafe® motor mower has2 speed ranges (slow/fast)selected by the operator with a mechanical control situated on the handlebars, an automatic parking brake with manual release mechanism for forced manoeuvres.

The versatility of the machine is guaranteed by an unlimited series of attachments, such as: cutter bars, heavy-duty mowers, lawn mowers and generally speaking all the attachments used for alpine haymaking and for uses in municipalities.

Hydrostatic Transmission

Mechanical transmission at power take-off by means of gears in an oil bath.

Transmission from the gearbox main shaft to the hydrostatic unit pump by means of cylindrical gears in oil bath with helical teeth.

Transmission from the hydrostatic motor to the gearbox by means of cylindrical gears in oil bath.

Thanks to a single lever placed on the handlebars (EasyGrip version) or a rotating knob, motorcyclist type (EasyRider version), the speed and direction of the machine can be adjusted continuously. This means an unlimited amount of gears are available for all operating requirements.

The automatic parking brake (Auto-hold) locks the machine in position at the grip limit even with the engine switched off, while a manual release mechanism protected by a safety lock to prevent accidental triggering allows forced manoeuvres to be carried out.

Direction Control

• EasyGrip: The 'EasyGrip' lever control guarantees ahigh operating comfort especially for those operations requiring frequent direction reverse, such as greens maintenance and typical uses in municipalities.

• EasyRider: The 'EasyRider' direction control by rotating knob, motorcyclist type, allows the operator to control the direction holding the handlebar with the right hand. This allows tobetter control the unit in deep slopes, such as cutting on hilly grounds. The knob rotates on ball bearings to reduce driving friction.

PowerSafe

The exclusive PowerSafe® clutchwith multiple steel discs in oil bath and flanged directly to the engine, provides the operator with a series of tangible advantages:

• Maintenance-free hydraulic clutch.
• Practically unlimited duration even if stressed with alternating movement attachments or with high inertia.

• No overheating even if stressed for a long time.
• No drop in performance at any operating temperature.

• Gentle and progressive engagement of the clutch lever, as well as minimal force required to keep the safety lever pressed.
• Elimination of preliminary action for engine start-up.

• Immediate machine and attachment shutdown if the handlebar is released. However, the engine continues to run.
• Dual desmodromic system to prevent work from being resumed accidentally.

• Extended to 5 years on the entire PowerSafe® clutch unit.

Steering Clutches

This original mechanism independently controls the steering clutch-brake mechanisms on the two wheels, affording the BCS 660 HY WS PowerSafe excellent and practical usage on steep slopes. This gives the machine maximum steering comfort, easy handling and perfect control of the machine in operation.

The steering clutch-brake mechanisms with multiple steel discs in oil bath are housed in closed cases on the two wheels.

The lever-operated steering controls, situated on either side of the handlebar grips, are hydraulically-operated. The right steering control is replicated on the left handlebar.
