Original quality for winegrowers: round belts for vine shoot removers at an attractive price
Why the round belt in the vineyard is crucial for the working result of your vine shoot remover.
Vine shoot removers such as the CLEMENS MULTICLEAN are established machines used by many wine-growing businesses for mechanical shoot removal and under-vine maintenance. Their rotating, flexible cords remove trunk shoots, water shoots and young growth from the vines without actively disturbing the soil.
However, these cords are exposed to high mechanical loads during daily use. Sooner or later, they need to be replaced. Anyone looking for a round belt with a diameter of 6.3 mm will frequently encounter the reference number CW630008600.
At Alphabelt, the RMW 6,3 beige Volta PU Rundriemen FDA is the same product from the same manufacturer, available at attractive conditions and supplied on a practical 30.5-metre roll.
In this article, you will learn why the material, diameter and hardness of the round belt are crucial for the working result and smooth operation of your vine shoot remover.
Shoot removal and under-vine maintenance in a single operation
Trunk shoots develop on the vine trunk below the actual canopy. If they are not removed, they compete with the fruit-bearing shoots for water and nutrients. They also make maintenance of the under-vine area more difficult and may impair air circulation around the trunk.
Manual shoot removal is reliable, but it requires a considerable amount of time and labour. For this reason, mechanical vine shoot removers frequently perform this work in larger vineyards.
Vine shoot removers work with rapidly rotating, smooth plastic cords. These brush along the vine trunk and remove young shoots that have not yet become woody. At the same time, unwanted vegetation between the vines is shortened.
CLEMENS describes the MULTICLEAN as a low-vibration mowing or mulching brush that removes trunk shoots and simultaneously eliminates weeds in the area between the vines without working the soil. The smooth and robust cords are designed to treat the vines as gently as possible.
Why the correct round belt is crucial
The round cords used are not ordinary mowing lines. The material, diameter, hardness and surface properties have a significant influence on the working result and must therefore be precisely matched to the application.
An unsuitable cord can:
- wear too quickly,
- work unevenly,
- cause stronger vibrations,
- place unnecessary stress on the vine trunks or even damage them,
- or fail to attach securely to the working shaft.
A beige PU round belt with a diameter of 6.3 mm is used for the corresponding CLEMENS application. The associated CLEMENS reference number is CW630008600.
The RMW 6,3 beige Volta PU Rundriemen FDA offered by Alphabelt is not a copy, but the same product from the same manufacturer that is also used for the CLEMENS round belt with reference number CW630008600. Alphabelt supplies the round belt as a 30.5-metre roll. This allows you to cut the required cord sections yourself to suit the configuration of your machine.
You therefore receive:
- the same manufacturer,
- the same material,
- the same diameter,
- the same Shore hardness,
- the same colour,
- and the same technical design.
The difference lies in the distribution channel and the price – not in the round belt itself.

Why polyurethane is the suitable material for vine maintenance
Polyurethane, or PU for short, combines elasticity with high wear resistance. This is exactly the combination required for a vine shoot remover.
During operation, the cords do not only come into contact with soft shoots and grass. They also encounter older vine trunks, posts, tying materials and other parts of the vineyard structure. The round belt must therefore deform flexibly without tearing immediately or losing length excessively quickly.
With a hardness of 95 Shore A, the belt is firm and resistant. At the same time, it remains sufficiently flexible to be used as a working cord on the rotating brush.
The smooth surface is also important. It supports uniform operation and reduces the risk of the cord becoming unnecessarily caught on rough surfaces, wires or plant material.
Which machines is the round belt intended for?
The reference number CW630008600 is assigned to the 6.3 mm round belt for CLEMENS shoot-removal and vine-cleaning machines.
The main focus is the CLEMENS MULTICLEAN machine family. CLEMENS offers the MULTICLEAN in several sizes for different vineyard systems and operating conditions:
- MULTICLEAN Standard
- MULTICLEAN XS
- MULTICLEAN XL
- single-sided attachments
- double-sided versions on suitable implement carriers
The standard version is designed for conventional vineyard systems. According to the manufacturer, wires and irrigation hoses must be installed at least 50 cm above the ground.
The compact MULTICLEAN XS is designed for low-training systems. CLEMENS specifies a minimum clearance of 35 cm for wires and irrigation hoses.
The MULTICLEAN XL has an extended working shaft and is particularly suitable for wider systems or applications in fruit growing.
As the configuration and design may vary depending on the model, year of manufacture and version, you should always compare the existing cord, spare-part number and machine documentation before ordering.
When should the cords be replaced?
The round belt is one of the classic wear parts of a vine shoot remover. The actual level of wear depends on many factors:
- condition and age of the vine trunks,
- strength of the trunk shoots,
- density of vegetation in the under-vine area,
- working speed,
- brush speed,
- distance from the vine trunk,
- number and condition of the posts,
- and ground contact of the cords.
The cords should be replaced at the latest when they are noticeably shortened, heavily frayed, torn or unevenly worn.
Uneven operation of the machine can also indicate an irregular configuration. If individual cords are missing or their lengths differ considerably, an imbalance may occur. This not only reduces the quality of the work, but may also place additional stress on the bearings, shaft and drive.
Uniform configuration improves the working result
When replacing the round cords, care should be taken to ensure the most uniform configuration possible. The individual sections should be cut according to the machine specifications and installed symmetrically.
Different cord lengths would cause some cords to work more intensively than others. As a result, the brush would treat some areas more aggressively while leaving shoots behind in other areas.
For a uniform result, it is therefore advisable to:
- inspect the old cords and attachment points,
- determine the required length using the previous configuration or the operating instructions,
- cut all sections to as close to exactly the same length as possible,
- configure opposite positions uniformly,
- and then carry out a short test run.
The operating and safety instructions of the machine manufacturer are always binding.
Choosing the correct time of use
The best working result is generally achieved when the trunk shoots are still young, soft and only slightly woody. At this stage, they are easier to remove and the mechanical load on the cords and vine trunk remains lower.
Anyone who waits too long must expect stronger shoots and increased wear. Heavily woody shoots may not be removed completely and may require additional manual work.
The machine settings should also be adapted to the condition of the vineyard. A higher speed or greater pressure does not automatically produce a better result. An overly aggressive setting can increase cord wear and may cause damage, particularly to young vines or previously damaged bark.
A short test operation in a manageable row helps to coordinate the speed, position and driving speed.
Check wires, hoses and tying materials
Before using a vine shoot remover, the vineyard system should be checked for low-hanging or loose components. These include in particular:
- irrigation hoses,
- tying wires,
- young plant-protection sleeves,
- loose vine clips,
- hanging cords,
- damaged posts.
The rotating PU cords are flexible, but they may catch and wind up loose components. This not only affects the working result, but can also damage the cords or the machine.
The minimum heights specified by CLEMENS for wires and irrigation hoses should therefore be observed.
Store round belts in a dry and protected location
If the entire roll is not used at once, the remaining material should be stored in a clean and protected location.
A dry storage location without direct sunlight and without continuous contact with oils, solvents or aggressive chemicals is suitable. The belts should also not be kinked or stored under heavy objects.
Careful storage of the round belts makes it easier to use uniform and undamaged cord sections during the next replacement.
