At the top of the league, we offer the KUHN FB 3130 and FB 3135. These fixed chamber round balers are engineered to deliver maximum capacity and density even in the most challenging conditions worldwide.

With a wide range of intake options, there’s certain to be a FB round baler to suit your operation. Choose between a non-cutting OPTIFEED rotor, a 14-knife OPTICUT cutting rotor or a 23-knife OPTICUT cutting rotor. 18 POWERTRACK rollers provide exceptionally high density and reliable bale rotation in all crop conditions.

The net binder with active stretch technology ensures a firm bale shape with constant net tension throughout the entire binding cycle. The FB 3130 and 3135 are also available with the KUHN TWIN-reel film binding system. You can conveniently control each of these balers from the comfort of your tractor seat with the in-cab terminals. The KUHN FB 3135 is fully ISOBUS compatible.

Your benefits

An intake system for every crop condition

Intake with 230 cm wide pick-up

Optimal crop pick up

The cam-steered pick-up on the FB 3130 and 3135 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. <br/><br/>

To better meet your operation's specific needs, there are three intake options available. Choose one of our INTEGRAL ROTORS – the non-cutting OPTIFEED rotor or the 14- or 23-knife OPTICUT cutting rotor.

INTEGRAL ROTOR Technology

Available for the FB 3130 and 3135 models 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.<br/><br/>

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 double feeding tines and integrated augers, helps even out the swath by spreading the crop evenly for consistent bales every time. The double feeding tine design offers optimal grip on the crop.

Cutting: OPTICUT Rotors

KUHN OPTICUT (OC) cutting rotors are designed for unlimited intake capacity and excellent cutting quality. OC cutting rotors, with patented 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 windrow 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. With GROUP SELECTION (FB 3135), the operator can choose to have 0, 4, 7, 7, or 14 knives in operation.
OPTICUT 23
The INTEGRAL ROTOR, with the 23-knife OPTICUT system, has the benefits of intensive cutting and mechanical protection. The 23-knife OPTICUT system provides a theoretical cutting length of 70mm. Each single knife is spring-protected against damage from foreign objects. With GROUP SELECTION (FB 3135), the operator can choose to have 0, 7, 11, 12, or 23 knives in operation.
GROUP SELECTION results in easy knife changing and an improved driver comfort.

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 a fast clearance in case of a blockage and enables you to quickly continue your baling operation.

Consistent, firm round bales

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.

Unmatched lifetime and trouble-free baling

All wear-resistant rollers are made of 3.2 mm thick high-strength steel. They are roll-formed and laserwelded with a single weld for optimal durability. <br/><br/>Thanks to the 50 mm double-raced bearings on the drive chain side, the baler withstands the toughest conditions. All bearings have central greasing, a BEKAMAX automatic bearing greasing system is optional. The rollers feature built-in scrapers to push the material out and away from the 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

Round bales with net biding and film 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 3130-3135 balers can be equipped with the KUHN Film binding, Net binding or Twine binding system.

Reliable and user friendly net binding system

FB balers feature a proven and reliable net binding system with active stretch technology and active net feed system for constant high net tension. Convenient net positioning and a clear net routing makes installing a new net roll a breeze.

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.
The double twine tube binding system reduces the binding cycle time

KUHN TWIN-reel film binding system

For silage conditions, film binding is the better option. FB 3130 and 3135 balers can be equipped with the patented TWIN-reel film binding system. This unique KUHN solution optimises silage quality at the lowest costs. TWIN-reel uses two regular 750 mm stretch-film rolls. Regular wrapping film enables you to use a much higher pre-stretch ratio compared
to conventional wide film binding systems. This reduces your film binding costs by
37% and extends the film change intervals by another 30%.
