With the development of the SB 1290 iD, KUHN offers you an intelligent and innovative answer to today's and tomorrow's challenges. This 'intelligent-DENSITY' model is designed to produce bales (120 x 90) with up to 25% higher bale density in tough dry straw conditions compared to conventional large square balers. The patented TWINPACT double plunger system is the basis of this increase in bale density, whilst avoiding high peak loads on the machine.

Apart from the density, the bale channel, driveline and transmission have been upgraded which lends to further cost savings for the operator. A 200hp tractor is more than capable of producing 500kg plus bales, providing you significant fuel savings. The result: a more profitable baling operation in both conventional crop production and the most challenging environments where energy crops and biomass are grown.

Your benefits

Extremely high-density bales, low power requirement

The TWINPACT plunger is divided into a lower and upper part

One plunger stroke - double impact

The KUHN SB 1290 iD features the patented TWINPACT double plunger system, an intelligent way to reach extremely high bale densities and avoid high peak loads on the machine. To achieve up to 25% higher bale density, the plunger requires twice the force of a conventional large square baler. The TWINPACT plunger is divided into an upper and lower part, which are connected with a triangle rod. The plunger impact on the bale is divided into two steps, increasing the applied force per surface area and thus bale compaction. Despite the heavier bales, the load on the machine is comparable with a conventional 120 x 90 baler, eliminating the need for an oversized driveline, flywheel and main frame.

The TWINPACT effect:
  • Ensures intelligent, efficient bale compaction whilst avoiding high peak loads on the machine.
  • Gives you the possibility to work with similar tractor sizes as with conventional 120 x 90 balers.
  • Produces bales that are 25% heavier in dry crop conditions.

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. The benefit of this sophisticated measuring method is that up to 5% higher bale density can be achieved when driving at a capacity of 25 t/h. 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. In silage applications, a square-edged bale indicates less air content, resulting in higher quality feed.

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 wads 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 costs.

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 wad 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 feederfork system. The fork makes a different movement that empties the pre chamber and pushes the perfectly formed wad into the bale chamber.
The pre-chamber system ensures consistently filled wads and results in heavy, square-edged bales.

The bale chamber

The specially designed bale chamber of the KUHN SB 1290 iD is the result of more than 35 years of experience in big square baling. An active pre-chamber filling mechanism with a newly designed mechanical feeder fork steering system, secures the production of evenly filled bales.
A 3.75m long bale channel combined with the pressure control system ensures optimal control of the bale density. Highly resistant, replaceable wear plates for baling in dry dusty energy crop conditions are integrated into the machine design. A funnel shaped pressure door and a 7-beam top door design guarantee perfectly shaped bales and extra friction.
With the 3.75m-long bale chamber of the SB 1290 iD, there is plenty of space to form a perfect bale.

The double knotting system

The SB 1290 iD is equipped with a double knotting system. Via electronic knotter monitoring, the driver has accurate information concerning twine tension at all times and receives an alarm if an issue arises. The knotting progress can be monitored directly from the tractor cab.

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.

All double knotter models are equipped with 2 hydraulically driven turbo fans. The agressive fans guarantee a clean knotter area for an optimal knotter performance.

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 pick-up is designed to match the full capacity of the machine. With an intake width of 230 cm, the baler is capable of working in all swaths. The reliable cam-track system will not let you down, even in the harshest conditions. To adapt the machine to your fields, you have the choice between fixed and pivoting pick-up wheels. The pivoting pick-up wheels are semi-pneumatic and therefore ideal for rough terrain and stony soils.

To better meet your operation's specific needs, there are two intake options available for the SB 1290. 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.
