2026 Kuhn FB 3125 Fixed Chamber Base

2026 Kuhn FB 3125 Fixed Chamber

The FB 3125 is ideal for livestock operations, custom balers and mid-size farms looking to maximize productivity and forage quality across a wide range of crops.

Engineered for hay and forage producers who demand durability, density and efficiency, the KUHN FB 3125 fixed chamber round baler delivers high-performance baling in a compact 4x4 package. Built with KUHN’s proven PowerTrack rollers and Integral Rotor technology, the FB 3125 ensures consistent bale formation and superior crop flow, even in tough silage or heavy hay conditions. Its robust construction, low-maintenance design make it an ideal choice for livestock operations, custom balers and mid-sized farms looking for increased efficiency and bale quality across a wide range of forages.

Features may include:

The reliable cam-track steered pickup is built for optimal crop intake, featuring a standard crop roller and a wide 90.55 in. (2.30 m) working width. With four rows of tines spaced at 2.40” (61 mm), it ensures consistent, efficient gathering. The pendulum design, cam-track guidance and overload clutch enhance durability and control. Fixed pickup wheels come standard.

Our Integral Rotor system is engineered for optimal performance with a compact design that minimizes the distance between the pickup and rotor—ensuring smooth, efficient crop flow. The integrated large-diameter feed auger boosts throughput while reducing strain on the system. With fewer wearing parts and a low power requirement, it delivers long-lasting reliability and significantly lowers maintenance costs.

Where chopping is not required, the OptiFeed rotor will feed the crop directly into the bale chamber for maximum throughput. The FB 3125 can also be equipped with a cutting rotor, the OptiCut 14. The 14 knives cut the crop to a maximum of 2.75" and each single knife is spring protected against damage. When the obstruction is passed the knife will automatically return to its cutting position.

The split driveline system ensures smooth, efficient operation by distributing power evenly across the machine. The right-hand side drives the bale chamber, while the left-hand side powers the rotor and pickup—delivering balanced performance and reliable functionality in every pass. The 18 PowerTrack rollers equipped with a unique ribbed profile provide optimal traction and compression. Together, with PowerLock, the KUHN fixed balers exceed the requirement in every aspect.

The 18 steel rollers, with an asymmetrical profile, ensure a reliable bale rotation without stoppages. The PowerTrack rollers start to rotate the core of the bale as fast as possible to ensure maximum compression. Thanks to the asymmetrical profile maximum rotation, traction and compression are assured for producing solid bales.

An advanced tailgate locking system features two integrated sensors that monitor bale growth, activating the binding process automatically once the bale reaches its maximum size, starting as early as 80% completion. The system is hydraulically locked for secure operation, ensuring consistent performance and peace of mind in the field.

Our proven active stretch net binding system ensures consistent, high-quality bale wrapping from start to finish. It features dynamic, uniform stretching with up to 10% pre-stretch for secure coverage. The adjustable net tension, controlled via a variable pulley, guarantees even net spreading throughout the entire roll, delivering reliable performance and professional results every time.
