Disc pre-pruner

Prétailleuse avec barres de coupe

Product overview

Function: TERRAL Pre-Pruners are used to prepare for the mechanical or manual pruning of vines. They save a considerable amount of time during the pruning process, so that this period can be reduced to a minimum. The purpose of this work is to make it easier to use the pruner.

Use: The pre-pruner is used before and during the pruning period (November to March). It is recommended for use on hardened wood in which the sap has already descended (or is in the process of descending). This makes it easier for the pre-pruner to cut and chip the wood, so it can move faster. Branch length has no affect on the machine’s performance

How it works: The speed of rotation, with sharp lower discs and blunt upper discs, results in a clean cut and efficient branch removal. The machine’s multiple settings make it suitable for all types of vineyards.

Hitch: The TERRAL Pre-pruner can only be mounted onto the front of the tractor, to combine pre-pruning with the use of another tool at the rear, such as the TERRAL shredder, or a soil-working tool. It can also be combined with a hydraulic power pack if the tractor’s flow rate is insufficient. The pre-pruner can work on one complete row.

Feed rate: from 2 to 6 km/h depending on how stiff the vine shoots are and how flat the soil is between vine rows.

Customer testimonials, feedback

The pre-pruner does a perfect and comfortable job, thanks to its automatic opening function as it detects vine stocks. I use cutter bars on the pre-pruner to make it easier for the trimmer to pass through. The reduced front overhang allows me to position the machine precisely.
