PRUNING MACHINES

The Potel-Triscol pre-pruning machine derives from the "Potel" trimmer, a machine with cut obtained through a cutting bar acting in vertical with respect to the row (1.70 m L, standard version), to be used for the pruning of the summer vegetation of the vines, with a chassis allowing the insertion of two horizontal blades (about 0.80 m L, standard version), in feathered position for the pre-pruning of the vines during the winter on vineyards grown in simple curtain, spurred cordon, GDC.

The use of "Potel Triscol" ensures an approximate reduction of the pruning costs by 25%.
The advancement speed of the machine is 1200/1600 m/h. A special mechanical sensor (rack surmounted by small rubber or steel wheels), positioned on every horizontal bar allows proceeding around the poles (minimum size 5x5 cm), without obstructing preventing the entrance of the shoots to be cut.
   

Different types of sensors are available depending on the type of plant on which you work. The distance between the horizontal bars can be varied manually through simple pressure screws.

 

POTEL-TRISCOL
Designed to be positioned on the lateral front part of every type of tractor through a suitable plate. The assembly and disassembly are facilitated by a trestle supplied with the equipment. The operation of the machine is completely hydraulic and is obtained through the hydraulic power outlet on the tractor or, on demand, through a hydraulic central assembled on the hoist. The movements of the machine can be controlled from the driver's seat through a 5-lever distributor: the first one, featuring an anti-shock safety system in compliance with the safety rules, has the function to operate the cutting bars; the second one adjusts the working heights (stroke of about 0.65 m); the third one guides the lateral displacement (stroke of 0,50 m); the fourth one controls the inclination of the cutting bar (+ 38°); the fifth one is available for further controls on demand. "Potel-Triscol" has an approximate weight of 160 kg.
DOUBLE ROLLER PRE-PRUNING MACHINE - COLOKLIN
This equipment is used for the winter pruning/shredding of the vineyards grown in espalier at low spurred cordon, to eliminate all seasonal vegetation, now become woody, above the fruit bearing cordon between the support wires of the row: this allows a final spare of 70/80% on labour costs. Pre-pruning machine consisting of 9 pairs of cutting discs (working capacity 80 cm approximately) on hydraulic double columns (possibility of inserting pairs of discs).
  • Hydraulic block with valves and flow divider
  • Electrical control for the emergency opening of the cages
  • Lateral position adjustment (mechanical translation)
  • Special chassis with hydraulic movements: lifting and inclination (possibility of fitting trimmer and defoliator)
  • Hydraulic central independent from the tractor, to be fitted on three points of the rear hoist (capacity of the tank 70 liters approximately, with pump and multiplier) ad directly connected to the power outlet of the tractor
  • Anchoring plate and support trestle for machine at rest

 

The roller pruning unit consists of a lopping retractor operating over the poles with electro-hydraulic rapid control. The cutting discs can be positioned depending on your type of plant (easily demountable spacers).

Adjustable retractor depending on the type of poles used.
