The KUHN SB 1270 X is a high-density baler, which performs in all crop conditions and provides you with the highest bale densities in the 120 x 70 segment. Thanks to its rigid design, the machine is able to resist the most challenging working conditions.

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:
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 highest bale density. This results in a higher transport and handling efficiency.
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?
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.
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.
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.
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.
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:
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.
Perform at maximum capacity with a highly secure intake system. Synchronised drive of components is made by gearboxes and shafts. This ensures a perfectly synchronised machine with easy maintenance. The heavy-duty driveline features self-resetting cam-clutches. The benefit of these clutches is that they offer the possibility to use the machine at maximum capacity without worrying about time consuming shear bolt replacements. The driveline layout is simple, clean, and easy to service and maintain while minimizing the overall number of moving parts.
To use the machine at maximum capacity, a flawless protection system is required. All main intake components of the KUHN large square balers are fitted with a cam-type clutch. With this non-stop safety system you can unblock the machine from the operator seat, in the event of an overload. The pick-up, INTEGRAL ROTOR, main drive and feeder fork are protected with cam-type torque limiters, which are automatically activated in the event of an overload. The respective cam clutch then activates and the intake is stopped. The clutch re-engages when the operator reduces the PTO speed.
The design offers perfect accessibility to the inside of the machine during daily inspection and maintenance. For more safety, the knotter deck is equipped with solid stairs and a safety railing. The safety railing can be folded down easily to reduce the height of the machine during transport. Moreover, the driver can benefit from optimal comfort thanks to the heavy flywheel, the load sensing hydraulics and the torque regulation system.
The load sensing hydraulic system is used for automatic axle locking, knife steering, roller chute and bale ejector functionalities. The hydraulic system can easily be switched mechanically to an open centre operation if using it in combination with a tractor without a load sensing hydraulic system.
