Darwin S
The Darwin S is a mechanical thinning unit without a support/mounting.
It is our flexible thinning unit and can be mounted in different ways. It is used on already existing machines in the vehicle fleet, e.g. a cutting machine, a telescopic loader or a hydraulic arm.
The Darwin S is mounted with the spindle in the direction of travel. The rotor carrier has a slight angle to the right towards the trees. Due to its design, the machine is always mounted with the spindle in the direction of travel, so a better view of the spindle is ensured and thus you can guide more easily the spindle on / in the tree crown / mold.
Characteristics
- Universal attachable thinning unit
- Robust construction
- Protected electronics and hydraulics
- Controlled thinning that you see directly after execution
- Thins without chemical use
- Increase in fruit size and quality by increasing early sugar allocation to limited number of fruit
- Reduces biennial tendencies
- Fast travel speed ensures high treated area per hour
- Thinning can be performed in all weather conditions
- Can be used for all current cultivars
Control unit
The spindle speed (RPM) can be comfortably and continuously adjusted with buttons on the control unit in the driver’s cabin to be optimally adapted to the driving speed.The set spindle speed in RPM is displayed exactly, and remains constantly at the set value, irrespective of whether the motor speed of the tractor is increased or decreased. By pushing the ESC-button (see image on the left) the spindle can be stopped at any moment, in order to exclude trees with smaller blossoms or to alternate trees in the thinning process.
- Exact display of spindle speed (rpm)
- Continuous adjustmentof spindle speed
- Set spindle speed remains constant, independently of the motor speed
- Temporarily stop of the spindle by pushing the ESC-button
- Comfortable adjustment from the driver`s cabin
