Pre-pruning machine
The Colombardo company includes among its pre-pruners various models designed to respond to any customer request.
In fact, we find two versions:
- “Triscol” side bar kit, applicable to the frame of one of our trimmers, for lateral processing.
- with double driving columns, climbing model for the complete processing of the wall to be pre-pruned.
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 8 pairs of cutting discs (working capacity 60 / 70 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)
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.
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.
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.
