Consistent, dense, high-quality bales

Picture of increased parts on a SB 1270 X

X for "Xtra" bale density

The SB 1270 X can reach up to 10% more density compared to standard 120 x 70 models. Several features were added to help achieve this density increase:
  • Extra strong main gearbox
  • Extra strong main frame and bale channel design
  • Extra dimension of bale channel cylinders

A perfect balance between capacity and density

The KUHN patented torque regulation system on all SB 120 cm bale channel models ensures a perfect balance between capacity and density. The system consists of plunger rod load pins that measure the plunger force and an angle sensor that measures the crank angle. Throughout the complete plunger cycle the exact torque is calculated so you can operate the machine at peak performance and achieve the hightest bale density. This results in a higher transport and handling efficiency.
The torque regulation system ensures a perfect balance between capacity and density.

POWER DENSITY: the KUHN Solution

Consistently shaped bales provide more than just aesthetic appeal. A dense, consistently filled bale represents quality in every form. Square bales are easy to handle and stack. In addition, they are much more stable during transport than a poorly formed bale. A perfect square-edged bale reduces the risk of air entrapment during wrapping. This stimulates conservation of the bale and ensures a better feed quality.

The KUHN POWER DENSITY system, a single feeder fork design, proves that a well-engineered active pre-chamber filling system can eliminate complexity. This pre-chamber system ensures consistently filled flakes and results in heavy, square-edged bales regardless of the swath condition. The single feeder fork combines two functions into one mechanism, eliminating unneeded components and complexity and resulting in lower maintenance cost.

How does it work?
  1. The INTEGRAL ROTOR actively delivers the crop to the pre-chamber.
  2. The feeder fork (blue) provides an active filling of the pre-chamber.
  3. The single-acting feeder fork continues to form the bale flake until the measuring plate (red) is pushed back with a predetermined force.
  4. Once the measuring plate is pushed back, it activates the second function of the feeder fork system. The fork makes a different movement that empties the pre-chamber and pushes the perfectly formed flake into the bale chamber.
The pre-chamber system ensures consistently filled wads and results in heavy, square-edged bales.

The bale chamber

With the 3.4m long bale chamber of the SB 1270 X , there is plenty of space to form a perfect bale. The combination of aggressive retainers and pressure door shape brings an aggressive compaction and gentle expansion of the bale. 46 plunger strokes per minute result in a high compaction capacity. The plunger is guided via 4 large rollers with a diameter of 125 mm for maximum service life.
With the 3.4m-long bale chamber of the SB, there is plenty of space to form a perfect bale.

The double knotting system

The SB 1270 X is equipped with a double knotting system. While baling, an upper (blue) and lower (red) twine is fed to the bale. Because the twine is not slipping around the bale, there is no tension on the twine during the bale formation.
Step 1: As the bale reaches the desired length, the needles (grey) are activated and move upwards towards the knotter to start the knotting cycle. In this first step the bale is finished with the first knot.
Step 2: Once the first knot has finished the bale, the second knot connects the upper and lower twine again so the next bale can be formed without stress on the twine during knotting.

The knotting process is monitored directly from the terminal, providing the driver with accurate information on twine tension during the baling cycle. An alarm goes off if an issue arises, allowing the driver to take action and prevent downtime accordingly.

Two massive hydraulically driven turbo fans are equipped as standard and deliver optimal knotter cleaning performance in the most challenging and dustiest conditions.

Optimal crop intake to meet your capacity needs

With a pick-up width of 230 cm, the baler is capable of working in all swaths

Optimal crop pick-up

The unique crop guard design, in combination with a high torque on the INTEGRAL ROTOR and on the feeder fork driveline, ensures a high intake capacity while offering extreme endurance. The balers make use of a 2.30 m wide cam tracked pick-up with no less than 5 tine bars, in order to allow the pick-up to run at a lower speed. Consequently, an excellent raking job and the highest versatility in various crop conditions is guaranteed.

To better meet your operation's specific needs, there are two intake options available for the SB 1270 X. Select from one of our patented INTEGRAL ROTORS. The OPTIFEED non-cutting rotor or the 23-knife OMNICUT cutting rotor.

INTEGRAL ROTOR Technology

Available across the entire KUHN square baler range, our INTEGRAL ROTOR technology can be found on OPTIFEED and OMNICUT models. This simple, maintenance-free intake system guarantees an enormous throughput capacity at all times. The short distance between rotor and pick-up 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 has rotor tines made out of Hardox® wear plates to offer excellent durability in abrasive crop conditions.
All KUHN balers, cutting or non-cutting versions, are equipped with the INTEGRAL ROTOR system.

POWER FEED ROLLER

Whether you are baling dry straw, hay or wet silage, the POWER FEED ROLLER allows you to take capacity to the next level. Difficult crop conditions or inconsistent swaths could pose a challenge for an intake rotor. With the KUHN POWER FEED ROLLER this belongs to the past. This driven crop roller actively follows the height of the swath. As a result, the crop is slightly compressed and evenly distributed when entering the intake rotor. Inconsistencies in the crop flow are smoothed out, delivering a steady crop flow towards the rotor.

Peak loads as a result of irregularities in the swath are avoided. The smooth and steady crop intake ensures a reduced power requirement and a smooth running machine. Moreover, wear on the machine is reduced as less strain is applied on the intake.

Your benefits are:
  • Unrivalled overall capacity
  • Excellent crop guiding in different crops and swath sizes
  • Less power peaks in the intake system
  • Smooth running of the machine
The KUHN POWER FEED ROLLER is a driven crop roller which enables a steady crop flow

Non-cutting: OPTIFEED rotor and Biomass OPTIFEED rotor

The 48 cm diameter OPTIFEED rotor design, where rotor tines - made out of HARDOX wear plate - and auger function are combined on one shaft, helps even out the swath by spreading the crop evenly for consistent bales every time. When crop cutting is not required, the OPTIFEED system ensures a controlled and consistent crop flow to the pre-chamber. With the rotor, an additional level of protection is given to the machine.

The 60 cm diameter Biomass OPTIFEED rotor design combines all the benefits of the standard OPTIFEED rotor with boltable rotor tines made out of Hardox wear plate for excellent durability and easy exchange. These rotor tines are specially designed for aggressive energy crops such as sugar cane leaves.

Cutting: OMNICUT 23 knifes (OC 23)

The OMNICUT 23-knife rotor (OC 23) offers a cutting length of 45 mm on the 120 cm wide bale channel models. With a rotor diameter of 60 cm, the rotor will process every swath that is placed in front of the baler. The knives on the OC 23 have individual hydraulic protection. This ensures a perfect cutting quality regardless of working speed and crop. The operation of the knife group configuration is easily done from the tractor cab via the terminal. The operator can choose from the following knife group configurations: 0 - 11 - 12 - 23. The boltable rotor tines made out of Hardox wear plate guarantee easy exchange. Together with the standard cassette system for easy knife changing, you not only invest in cutting quality but, above all, in driver comfort.
