635 HY PowerSafe®

Motor mower with hydrostatic transmission and PowerSafe® hydraulic clutch | power up to 10.7 hp | cutting width up to 210 cm.


The 635 HY PowerSafe® is a motor mower with hydrostatic forward motion transmission that can be continuously adjusted with 2-speed ranges (slow/fast).

With one lever only on the handlebar, the operator can continuously vary the speed and direction of the machine: this means an unlimited amount of gears are available for all operating requirements.

The lever control ensures high operation comfort especially during haymaking, greens maintenance, snow removal and typical municipality use, which involves many direction changes.

Thanks to their handling and ease of use, the hydrostatic motor mower 635 HY PowerSafe® is well performing any type of use and can be used by a vast range of users: from hobby to professional farmers, and from individuals to the greenery caretaker. 

The PowerSafe® hydraulic clutch, patented and exclusive to the BCS Group, also guarantees maximum reliability, comfort and total safety for the operator.

Hydrostatic transmission

sample powersafe
The compact hydrostatic pump-engine unit is made of light alloy so that the machine can be easily manoeuvred and positioned on the gearbox. 

Characterised by a high pressure circuit which is separate from the one of the PowerSafe® clutch, the machine is fitted with an axial-centrifugal fan to cool the hydrostatic unit.

Direction control

sample powersafe
  • EasyGrip: The "EasyGrip" lever control guarantees a high 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 to better control the unit in deep slopes, such as cutting on hilly grounds. The knob rotates on ball bearings to reduce driving friction.


For both direction controls, a notch sector allows the operator to easily and repeatedly fix the position of the lever or of the knob. A central area without notches lets the lever or the knob to be positioned as desired, so that the machine can operate at a very slow speed.
