The KUHN FB 3125 fixed chamber baler is a reliable solution for small- to mid-scaled farms producing their own baled forage. It performs in various crops and conditions, throughout the season. 

Produce perfect bales using the proven KUHN 18-roller chamber concept. These high-quality rollers feature the POWERTRACK profile for maximum bale traction. Choose between a non-cutting OPTIFEED rotor and 14-knife OPTICUT cutting rotor. 

The intuitive operation makes it easy to use, and machine maintenance is effortless. With the VT 30 terminal you are in control and have insight into your baling and binding processes. 

Also, benefit from the market’s most reliable net binding system. For constant high net tension, the KUHN net binding system provides active net stretch and consistent net spreading. The FB 3125 can also be equipped with Net + Twine binding.

Your benefits

Intake system that can handle every crop condition

Intake with 230 cm wide pick-up

Optimal crop pick up

The cam-steered pick-up on the FB 3125 maximises the full capacity of the machine. With a working width of 230 cm, the machine is capable of working in all windrows and will not let you down, even in the toughest conditions. Straight pick-up tines help release the crop and reduce crop wrapping. Camless-shaped crop guides result in an efficient and gentle pick-up. A cam track pulls the tines straight down in the rearward position to avoid wrapping, making this the only hybrid pick-up on the market today. Therewith, it can handle every kind of crop, from long straw up to the shortest autumn silage or crops with fragile leafs. The pick-up features standard pendulum frame and optional pivoting pick-up wheels to allow the pick-up to adapt to changing field conditions.

To better meet your operation's specific needs, there are two intake options available. Choose one of our INTEGRAL ROTORS – the non-cutting OPTIFEED rotor or the 14-knife OPTICUT cutting rotor.

INTEGRAL ROTOR Technology

Available for the FB 3125 model is our INTEGRAL ROTOR technology found on OPTIFEED and OPTICUT 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 reduces crop damage.

The INTEGRAL ROTOR has rotor tines made out of Hardox® wear plates. Hardox® combines extreme hardness and toughness to reduce rotor tine wear.
The short distance between rotor and pick-up tines maintains consistent crop flow.

Non-cutting versions

The OPTIFEED rotor design, with single feeding tines and integrated augers, helps even out the swath by spreading the crop evenly for consistent bales every time.

Cutting: OPTICUT Rotor


KUHN OPTICUT (OC) cutting rotors are designed for unlimited intake capacity and excellent cutting quality. OC cutting rotors, with elliptical-shaped rotor tines, are acknowledged by users as one of the best cutting systems on the market. The silage is guided and drawn down to the knives from an early stage which improves flow and cutting performance while requiring minimal force - this also prevents unwanted blockages.

OPTICUT 14
The INTEGRAL ROTOR, with the 14-knife OPTICUT system, is designed to even out the swath and force-feed the crop into the baler for maximum throughput. The 14-knife OPTICUT cutting system provides a theoretical cutting length of 70 mm. Each single knife is spring-protected against damage from foreign objects.

DROPFLOOR & Rotor disengagement

The floor and knives can be hydraulically lowered from the comfort of the tractor cab in the case of a rotor blockage. After the blockage is cleared, they can easily be brought back into work position.

In extreme circumstances, double security is provided by a standard rotor disengagement clutch. This will enable the operator to bind and eject the bale from the chamber before continuing.

Both the rotor disengagement and DROPFLOOR technology ensure fast clearance in the case of a blockage and enables you to quickly continue your baling operation.

Consistent, firm round bales

The POWERTRACK profile of a roller

POWERTRACK

To compress the crop into bales with a consistent size and density, the baling process has to be as effective as possible while being gentle on the crop. The rollers with unique asymmetrical POWERTRACK profile start to rotate the core of the bale as fast as possible to ensure optimal compression.

Fast, perfect bale formation

18 high-quality rollers are at the core of the KUHN fixed chamber concept. All rollers feature a POWERTRACK profile for maximum bale traction, resulting in a reliable bale start and a high bale density. A minimum of space between the rollers maximises bale contact and reduces crop loss.

Robustness for all your baling operations

The KUHN fixed chamber baler concept includes rollers that are laser-welded from a single component. This provides maximum strength and performance. Machine durability, bale shape and density are enhanced by the heavy-duty driveline and high quality bearings. The baler is also fitted with lifetime lubricated maintenance-free chamber roller bearings, and automatic chain lubrication for efficient machine maintenance.
Heavy-duty driveline and high quality bearings

POWER LOCK density control

High and accurate bale density. Consistently sized, well-formed bales. All this is achieved through the unique POWER LOCK density control system. Strong hydraulic tailgate cylinders in combination with adjustable hydraulic pressure keep the tailgate closed while forming the bale. These cylinders act as a hydraulic lock and also prevent the baler from overloading.
The KUHN POWER LOCK density control system ensures well-formed bales.

Bale growth detection

The POWER LOCK system allows early bale growth detection,
performed by highly accurate tailgate sensors.The driver is
informed as early as 80% bale filling so there is still enough time
to perfect the bale in terms of density and shape. You are notified about the baling process via the bale growth indicator. The binding process can be started automatically when the maximum bale size is detected.
Highly accurate sensors allow early bale growth detection.

SECURE BINDING SOLUTIONS

Firm shaped bales with net binding

Firm bale shape

KUHN bales stand out in bale density and shape. After the bale has left the bale chamber, it is important to keep it in perfect shape and condition. Our binding techniques offer maximal holding force and optimal bale shape retention. FB 3125 balers can be equipped with the KUHN Net binding or Net+Twine binding system.

Reliable net binding system

The FB 3125 features the proven and reliable KUHN Net binding system which provides net stretch and consistent net spreading. Convenient net positioning and a clear net routing makes for a simple roll exchange.

Twine binding

When using the double twine binding system, the binding cycle time is reduced to a minimum. In the twine binding cycle, both of the twines start at the bale edge and overlap before moving to the centre of the bale. In the centre of the bale, they overlap again. This ensures that the twines are fixed and that there are no loose ends.
