PRE-PRUNER MP 122

MODEL OPTIMA STRADDLE TRACTOR

The cutting height must be adapted according to the pruning method. The rotational speed of the cutting elements must be adapted to the travel speed of the tractor, so that the machine can grip the branches properly and clean the upper tying wire. The travel speed is variable, it depends on the vine variety (drooping or upright) and on the tying (proper tying wires tension). It is generally around 5 km/h. It can be much higher but, in this case, the approach of the posts is less accurate and leaves more unpruned branches.

  • Working height

    185 mm

  • Flow rate

    50 l/min

  • Weight

    160 kg

FEATURES

A frame with two disc modules equipped with blades performing a shear cut, reduced projections thanks to a low rotational speed (about 260 RPM).
The shape of the disc ensures a good grip on the branches and a regular feeding of the machine, without damaging the tying wires Its thickness prevents the wire from being cut.
The controls are centralized in a hydraulic block, the totally flat bottom section of the discs prevents any stripping of the spurs.

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
  • Working speed up to 10 km/h
  • Available in 2 versions (short and long frame) with a stack of 6 to 28 disks with intervals of 60 or 90 mm

ADVANTAGES

  • The shape of the disc ensures a good grip on the branches and a regular feeding of the machine, without damaging the tying wires
  • The 60 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
  • Low-maintenance, lightweight (from 145 to 270 kg) and reduced flow rate
  • Reduced projections thanks to a low rotational speed
  • La partie infÃrieure des disques est totalement plate, ce qui Ãvite tout dÃchaussement des coursons sur les cordons

Models for straddle tractors

The sharp disk for a cutting quality comparable to that of pruning shears

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).


Side cuts option

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 option

The optical detection operates for any type of post (wood, steel, concrete), but there must be no leaves. Also, the posts shall not show any holes in the reading axis and have a cross-section larger than or equal to 25 mm. The inductive detection (not shown) only operates with steel posts. But it allows pre-pruning immediately after the harvest, even if there are leaves.
