Robust and reliable, Rinieri vineyard pruners deliver precise pruning cuts and are available in a wide range of models designed to meet every farm’s needs
The primary goal of every winegrower is to harvest healthy grape clusters suitable for high-quality winemaking. However, vigorous vine growth does not always translate into better harvest quality, as the leaves most effective in feeding the grape clusters are roughly the first twelve along the shoot. Beyond this point, their contribution to production ranges from minimal to negligible.
Vineyard trimming is therefore a fundamental practice, both to maximise the photosynthetic efficiency of the most important leaves and to improve canopy ventilation, thereby reducing the risk of fungal diseases.
The choice of mechanical equipment must meet specific requirements, including cutting precision to prevent shoot fraying, operational flexibility of the over-the-row blade carrier structures, and good visibility to ensure operator safety and comfort. The Rinieri trimmer range meets these technical criteria, comprising 29 models developed to satisfy every possible farm requirement, both in terms of training systems and budget.
A perfect synthesis of these needs is represented by the “Plus” versions of the “CRV Vision 1” and “CRV Vision 2” models. These two trimmers feature an inverted “U”-shaped frame whose low-profile, front-mounted structure provides improved operator visibility, making them ideal for trimming operations even on hilly terrain or slopes with significant lateral gradients.
Both models operate using rotary knife bars 40 cm in length — 45 cm for the topper units — made of stainless steel to ensure minimal wear and reduced maintenance. Their operational focus differs, however: the “CRV Vision 1 Plus” is designed for single-row trimming, while the “CRV Vision 2” version allows simultaneous operation on two rows at speeds of up to 15 km/h.
Common to both implements is the option to choose the number of knives on the bars: three, four, five or six along the vertical, and two or three blades with topper function. This results in an exceptionally broad and deep product offering, to be selected according to row height and canopy thickness.
The number of blades also determines the overall height of the structure, ranging from 105 cm for the three-knife version, to 140, 175 and 210 cm for the higher configurations. Available working widths are 75 or 105 cm, allowing the integration of two or three topper blades.
Finally, to better adapt to different row spacings, the frames allow lateral displacement that can be carried out either manually or hydraulically, with ranges of 20 and 25 cm respectively for the “V2” frame, and 20 and 30 cm for the “V1 Plus” frame. Further enhancing the adaptability of Rinieri trimmers are a 60 cm hydraulic lift and a hydraulic tilt system, offering 15 degrees of movement both upward and downward to better follow the contour of the rows.
