PRINCIPLE
- A frame with two disc modules equipped with blades performing a shear cut. The discs are driven by 2 hydraulic motors. All pre-pruner functions are centralized in a hydraulic block.
- Cutting modules opening and closing is controlled by a control switch.
- Rotational speed of the discs is approximately 280 RPM for a flow rate from 24 to 40 l/min.
- Available in four frame versions with stacks varying from 6 to 28 disks with intervals of 60 or 90 mm.

ADVANTAGES
- The shape of the disc ensures a good grip on the vine shoots and a regular feeding of the machine, without damaging the tying wires.
- The 90 mm interval between the disks furthers the cleaning of the tying wires thanks to the cutting sections mounted on a carrier disk whose thickness prevents the wire from penetrating between the teeth of the cutting sections.
- Reduced maintenance, lightweight (from 145 to 270 kg) and low flow rate.
- Reduced projections thanks to a low rotational speed.
- The bottom section of the discs is totally flat, preventing any stripping of the spurs.
- Working speed up to 10 km/h.
SHARP DISK
- A circular disk with a sharp edge on one of the cutting modules, facing a toothed disk on the other module, ensures a clean sharp cut, without cracking of the wood. The cutting effect of the disk avoids pinching the wood, which is a common phenomenon in shear cutting. A specific configuration of this equipment ensures the respect of the environment (posts and tying wires).
OPTIONS
SIDE CUTS
- The side cuts are supplied with safety retraction and manual setting of the cutting angles and width.
- They are serially connected with the pre-pruning head and require no additional flow rate.
AUTOMATIC OPENING
- The optical detection operates for any type of post (wood, steel, concrete). There must be no leaves left. The system requires posts without holes in the reading axis and with a cross-section larger than or equal to 25mm.
- The inductive detection (not shown) only operates with steel posts. But it allows pre-pruning immediately after the harvest, even if there are leaves.
