Professional Mechanical Trimming
Mechanical trimming is an essential operation for vineyard management, aimed at improving grape quality and plant health. This process involves the removal of the apical parts of the shoots, promoting balanced growth and better light exposure.
Ideal Timing for Trimming
Mechanical trimming should be carried out during the summer season, typically between June and July. It is important to perform the operation when the shoots have reached a sufficient length, usually between 30 and 40 cm beyond the last containment wire. Trimming at this time helps prevent excessive shading of the clusters, improving ripening and reducing the risk of fungal diseases.
Rinieri Trimmers: Models and Features
Rinieri offers a wide range of professional mechanical trimmers designed to meet the diverse needs of viticulturists. Rinieri trimmers are divided into two main categories, based on the type of cutting bar: dual-blade and rotary knife.
Sickle Bar Trimmers (CRL)
The trimmers with sicke bar CRL are known for their robustness and precision. These machines feature a double blade-tooth alternative movement that ensures a clean and precise cut of the shoots. The maximum forward speed is 3/4 km/h depending on the vineyards. The models include:
- CRL ECO-2 I and L: double trimmer with vertical or vertical and top bars
- CRL VISION-1 I and L: single trimmer with vertical or vertical and top bar
- CRL TOWER-1 I and L: single trimmer with vertical or vertical and top bar
- CRL VISION-2 I and L: double trimmer with vertical or vertical and top bars
- CRL TOWER-2 I and L: double trimmer with vertical or vertical and top bars
- CRL VISION-1 PLUS: inverted U-shaped single over-row trimmer
- CRL TOWER-1 PLUS: inverted U-shaped single over-row trimmer
- CRL VISION-2 PLUS: inverted U-shaped double over-row trimmer
- CRL TOWER-2 PLUS: inverted U-shaped double over-row trimmer
Rotary blades Trimmers (CRV)
CRV trimmers use rotary stainless steel blades or knives, offering a quick cut with a maximum forward speed of 5/6 km/h. These machines are lightweight and maneuverable, ideal for fast and efficient trimming. The new Flow knives perform a cleaner and sharper cut and require less maintenance because they are self-cleaning. The main models include:
- CRV ECO-2 I and L: double trimmer with vertical or vertical and top bars
- CRV VISION-1 I and L: single trimmer with vertical or vertical and top bar
- CRV TOWER-1 I and L: single trimmer with vertical or vertical and top bar
- CRV VISION-2 I and L: double trimmer with vertical or vertical and top bars
- CRV TOWER-2 I and L: double trimmer with vertical or vertical and top bars
- CRV VISION-1 PLUS: inverted U-shaped single over-row trimmer
- CRV TOWER-1 PLUS: inverted U-shaped single over-row trimmer
- CRV VISION-2 PLUS: inverted U-shaped double over-row trimmer
- CRV TOWER-2 PLUS: inverted U-shaped double over-row trimmer
Multipurpose Frames
Rinieri professional trimmers can be mounted on various multipurpose frames, each with specific characteristics to adapt to different vineyard conditions:
- Tower Frames: Robust central structure, ideal for flat terrains.
- Vision Frames: Better visibility and adaptability to hilly terrains, with separate inclinations and lifts.
- Eco Frames: Simple and reliable structure with manual adjustments.
The frames are available in single and double versions, allowing both sides of the row to be worked in one pass, optimizing time and resources. Other work heads such as the suckering machine, prepruning machine, and leaf remover can also be attached to the frames.
Conclusion
Choosing the right timing for trimming and using Rinieri trimmers ensures efficient and sustainable vineyard management, improving grape quality and reducing operational costs.
