The LSB 1270 is one of the four KUHN large square balers in the 120 crop flow channel segment. The baler is ideally suited for diverse conditions and various crops such as silage, hay, straw, lucerne, maize straw and sugar cane leaves. Where crop cutting is required, the 23-knife OMNICUT system, with integrated cassette system for easy knives access, will do the job. There is also a non-cutting model available.

All main intake components are fitted with a cam-type clutch. A synchronised drive of components is achieved via gearboxes and shafts. This robust driveline ensures a perfectly synchronised machine with easy maintenance. The INTEGRAL ROTOR combined with the POWER DENSITY pre chamber system results in a low power requirement. The bales are tied together by the 6 single knotters supported by the unique TWIN STEP system for maximum tension on the twine.

Your benefits

Consistent, dense, high-quality bales

The pre-chamber system ensures consistently filled wads and results in heavy, square-edged bales.

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 cost.

POWER DENSITY - How does it work?

  1. The INTEGRAL ROTOR actively delivers the crop to the pre-chamber.
  2. The feeder fork (blue) actively fills 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 feeder fork system. The fork makes a different movement that empties the pre chamber and pushes the perfectly formed wad into the bale chamber.
Power Density � The KUHN Solution

The bale chamber

With the 3.4m long bale chamber of the LSB 1270, there is plenty of space to form a perfect bale. The combination of aggressive retainers and a specific 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.

TWIN STEP knotting system

The unique TWIN STEP knotting system consists of a single knotter and smart system that releases the twine tension during the knotting cycle. The result is a secure, easy to adjust knotting system.
While baling, the knotters (blue) are at rest and the twine is guided by the twine tension release lever (red), in the vertical position. Tension is held on the twine to ensure maximum density in the bale.
Step 1: As the bale reaches the desired length, the needles (grey) are activated and move upwards towards the knotters to start the knotting cycle.
Step 2: By pivoting backwards, the tension lever (red) releases the twine and consequently reduces tension to the knotter during the knotting cycle. This guarantees a perfect knotting process.

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 LSB 1270. Select from one of our patented INTEGRAL ROTORS � The OPTIFEED non-cutting rotor or the 23-knife OMNICUT cutting rotor.

INTEGRAL ROTOR Technology

All KUHN balers, cutting or non-cutting versions, are equipped with the INTEGRAL ROTOR technology. This simple, maintenance free intake system ensures even feeding regardless of the various (crop) conditions. The short distance between the rotor and pick-up yields an outstanding crop flow. This force-fed intake makes higher forward speeds possible for outstanding productivity and reduced crop damage.

All rotor tines are made out of high-quality steel and offer excellent durability in abrasive crop conditions.

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 perfect cutting quality regardless of working speed and crop. By moving only two levers, the operator can choose from the following knife group configurations: 0 � 11 � 12 � 23. Together with the standard cassette system for easy knife changing, you not only invest in cutting quality but, above all, in driver comfort.

Robust driveline and maximum security

Gearboxes and shafts ensure a perfectly synchronised machine with easy maintenance.

Robust driveline

Synchronised drive of components is achieved through the gearboxes and shafts. This ensures a perfectly synchronised machine with easy maintenance. The driveline layout is simple, clean, and easy to service and maintain while minimising the overall number of moving parts.

Instant protection

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. Another 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.

Equipment

Productivity at your fingertips<br />User interfaces are the key to achieving the productivity you expect from your KUHN machine. We listened carefully to the users of our machines to develop our new user interfaces and terminals. The objective is to have a clear view of what your machine is doing at any time and to have all important settings at your fingertips. This ensures that you have full control of your machine.
