Kuhn VB 3260

Intake Options

Optimal Crop Pickup
All VB 3200 models feature a wide pickup with standard crop roller. The pickup is designed to maximize the full capacity of the machine. With a working width of 83” or 91”, the machine can work in all windrows and conditions. Straight pickup tines help release the crop and reduce crop wrapping. The pickup roller compresses the crop against the pickup tines, to even out the windrow. This reduces friction, thus decreasing leaf loss and increasing baler efficiency. The 91” rotor pickup of the VB 3260-3290 features standard pendulum frame and pivoting pickup wheels, allowing the pickup to adapt to changing field conditions. Camless-shaped crop guides result in more aggressive and efficient pickup by exposing more of the tine when needed and by pulling the crop away from the tines as it approaches the intake. A cam track pulls the tines straight down in the rearward position to avoid wrapping, making this the only hybrid pickup on the market today. To better meet your operation's specific needs, there are four intake options available. Choose the direct feed intake system or select one of our three patented Integral Rotors – the non-cutting OptiFeed rotor or the 14- and 23-knife OptiCut cutting rotors. Availability dependent on VB model – See Specifications

Direct Feeding System
When crop cutting is not required, the Direct Feed system allows for unrestricted intake for maximum capacity in all crop conditions. In heavier conditions, like heavy, dry hay and cornstalks, the top roller acts as a pre compactor, which is powered by the primary driveline of the baler. There are no stuffer fingers which can disturb the flow and therefore limit the intake capacity. This generates a huge input potential and prevents plugging of the unit resulting in a high output and minimum downtime.

Integral Rotor Technology
Available across the entire VB 3200 range is our patented Integral Rotor technology found on OptiFeed and OptiCut models. This simple, low-maintenance intake system guarantees an enormous throughput capacity at all times. The short distance between rotor and pickup tines maintains consistent crop flow. The design of this force-fed intake makes higher forward speeds possible for increased productivity and reduced crop damage. The Integral Rotor on all models are provided with rotor tines made out of Hardox® wear plates (except VB 3255-3285). Hardox combines extreme hardness and toughness to reduce rotor tine wear. Longer wearing life of the rotor tines will help to provide time and money savings for the operator.

Non-Cutting, OptiFeed Rotor
The OptiFeed rotor, with single feeding tines and integrated augers, provides a consistent flow of crop into the bale chamber. This rotor design helps even out incoming windrows for consistent bales every time.

Cutting, OptiCut Rotors
The OptiCut (OC) cutting rotors are designed for unlimited intake capacity and excellent cutting quality. KUHN (OC) cutting rotors, with elliptical shaped rotor tines, are acknowledged by users as one of the best cutting systems on the market. The silage is guided and drawn down to the knives from an early stage which improves flow and cutting performance and also prevents unwanted plugging.

OptiCut 14
The Integral Rotor, with the 14-knife OptiCut system, is designed to even out the windrow and force-feed the crop into the baler for maximum throughput. The 14-knife OptiCut cutting system provides a theoretical cutting length of 2 ¾". Each single knife is spring protected against damage from foreign objects. With group selection (VB 3165 & 3195 models) the operator can choose to have 0, 4, 7, 7, or 14 knives in operation.

OptiCut 23
The Integral Rotor with the 23-knife OptiCut system from KUHN has the benefits of intensive cutting and mechanical protection. The 23-knife OptiCut system provides a theoretical cutting length of 1 ¾". Each single knife is spring protected against damage from foreign objects. With group selection the operator can choose to have 0, 7, 11, 12, or 23 knives in operation.

Bale Formation

Consistent, Firm Round Bales

Progressive Density – The KUHN Solution
The Progressive Density system has proven its value on all KUHN VB balers. The system increases tension as the bale grows providing a firm bale with a tough outer shell. For even more density, Progressive Density Plus is available as an option on VB 3260-3290 models. Progressive Density Plus delivers up to 10% greater densities in dry crops such as hay, straw and cornstalks.

How Does It Work?
As the bale grows within the bale chamber, the belt tensioning arm is subjected to steadily increasing resistance from two hydraulic cylinders and a spring tensioner. So as the diameter increases, the bale’s density does too. The result is a very firm bale with a moderate core – not too soft, not too hard. With a tougher outer layer, straw bales will be more tolerant to bad weather conditions, while silage bales will maintain their shape for improved stacking and easier handling.
