2025 Kuhn SB 1290 iD Large Square Baler Optifeed

The SB 1290 iD is designed to intelligently produce high density bales. Thanks to the patented TwinPact plunger system, the baler has a lower power requirement than competitive high density balers while still making heavier bales resulting in a more profitable baling operation.

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 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, while avoiding high peak loads on the machine.

Coupled with the TwinPact plunger, the bale channel, driveline and transmission have been upgraded which lends to further cost savings for the operator. A 200-horsepower tractor is more than capable of producing 1100 pound (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 straw and biomass crops are grown.

The KUHN SB 1290 iD features the patented TwinPact double plunger system, an intelligent way to reach high bale densities while reducing 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 3x4 baler, eliminating the need for an oversized driveline, flywheel and main frame.

The TwinPact effect:

• Ensures intelligent, efficient bale compaction while avoiding high peak loads on the machine.

• This intelligent design gives you the possibility to work with similar tractor sizes as a conventional 3x4 baler.

• Produces bales that are 25% heavier in dry crop conditions.

The pickup is designed to match the full capacity of the machine. With an intake width of 90", 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 rocky fields.

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 OptiCut cutting rotor.

Perform at maximum capacity with a durable intake system. Synchronized drive of components is made by gearboxes and shafts. This ensures a perfectly synchronized 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 reliable drive protection system is required. All main intake components of the KUHN large square balers are fitted with a cam-type clutch.
