Vineyard topping machine

rotary-knifehydraulichigh

The Terral 2-knife full-row Vision trimmer is a double-row vineyard maintenance machine manufactured in France, designed to remove side and top green foliage during the vegetative cycle. It adapts to different vineyard layouts and can be mounted on the tractor front or rear with multiple chassis and mounting options.

Overview

• Function: Maintains the plant system of vine rows by cutting green wood that grows on the sides and top of the rows (lopping).
• Use: For use during the vegetative cycle (April–August) on green, non-lignified shoots; shoot length does not affect performance.
• How it works: Rotation speed, blade sharpness and the cutting panel angle deliver a clean cut; adjustable angles and spacing allow adaptation to diverse vineyard configurations.
• Hitch / Mounting: Mountable on the tractor front (Vision chassis for full forward visibility), on the rear 3-point hitch (CAT1 or CAT2) or on a wheeled bogie or cart.
• Feed rate: Recommended travel speed 6–15 km/h depending on shoot stiffness and inter-row evenness.
• Regional names:
  • “écimeuse” or “pruning machine” (southeastern France)
  • “rogneuse” or “leaf cutter” (southwestern and northeastern France)
  • “faucilleuse” or “scythe machine” (Charentes, Loire)
  • “écourteuse” and “estrapeuse” (other regions)

Versions, options and equipment

• Trimmer versions: Side panels with 5 blades (170 cm cut) with optional tiltable last blade for sylvose cut; top panels with 2 to 3 blades (75–110 cm cut).
• Hydraulic & adjustments: Independent hydraulic height adjustment for top panels; independent hydraulic side height, side gap and crop thickness adjustments; hydraulic adjustments available for many components.
• Feeding & control: Multi-position adjustable rotary feeder; measuring rulers to position jack cylinders; electrohydraulic joystick control available as option.
• Drive / motors: 6–10 heavy-duty hydraulic motors depending on model; blade hub and motor counter-bearing for durability.
• Mounting / chassis: Vision compact double-girder molded-steel chassis; front mounting bracket; rear 3-point hitch (CAT1/CAT2) or mounting for 2-wheel cart or 4-wheel bogie.
• Safety & mobility: Spring-return safety device on side panels; gravity-return safety on upper panels (can be secured with screw); manual side panel angle adjustment; foldable plate for upper panels for road transport or storage; storage supports.
