Darwin mechanical blossom thinning

Ensure profitable harvests with increased fruit quality and reduced labor bill!

 

• 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

Characteristics

Excellent fruit size and quality achieved by mechanically thinning with Darwin

Mechanical thinning with Darwin is safer and can be more effective than thinning with chemical substances. It’s also quicker and less labor intensive than manual thinning.

Equipment variants

Mounting device front plate

For mounting without a front hydraulic system.

The holes are available for the most common tractors, otherwise the mounting plate has to be adapted individually.

Mounting device front hydraulic

For mounting on the (3 – point hitch) front hydraulic, for category I and II.

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 right) 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 adjustment of spindle speed
• Set spindle speed remains constant, independently of the motor speed
• Temporarily stop the spindle by pushing the ESC-button
• Comfortable adjustment from the driver’s cabin
