Your benefits

An intake system that can handle every crop condition

230 cm wide pick-up

Optimal crop pick up

The cam-steered pick-up on the FB 3100 Series maximizes 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 fragaile 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- or 23-knife OPTICUT cutting rotor.

INTEGRAL ROTOR Technology

Available across the entire FB 3100 range 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.

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.

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

Producing silage and hay bales each season can be tough and well thought-out designs are demanded. 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 POWERTRACK rollers start to rotate the core of the bale as fast as possible to ensure optimal compression.

Fast, perfect bale formation

The redesigned heart of the balers consists of 18 POWERTRACK rollers. The
rollers have symmetrical profiles which generate exceptionally high density and reliable bale
rotation in all crop conditions. All rollers are made of 3,2 mm thick high-strength steel
which are roll-formed and laser-welded out of 1 metal sheet for optimal durability. In
addition, a minimum of space between the rollers reduces crop loss.

Fast tailgate detection

The tailgate opens and closes in ≥ 4,5 seconds (60 l/min oil flow) thanks to its stable design with torsion pipes. Strong hydraulic tailgate cylinders keep the tailgate closed and ensure a consistent bale size with maximum bale density. These cylinders act as a hydraulic lock and prevent the baler from overloading (POWER LOCK). Highly accurate tailgate sensors monitor the bale growth as from 80%. You are notified about the baling process via the bale growth indicator. In addition, the FB 3135 allows you to guide the baler according to the left-right bale chamber filling indication displayed on the terminal for extra operator comfort. This results in optimum bale shape and density.

Highest density and improved lifetime

The rugged driveline with new gearbox design consists of a split driveline. The bale chamber drive on one side and rotor plus pick-up drive on the other ensures a smooth operation and an even power transfer. The main drive and bale roller chains are made up of high-strength 20B (1¼) chains with a standard Beka-Max continious chain oiling system, which contributes to an improved lifetime.
Thanks to the 50 mm double-raced bearings on the drive side main load points, trouble-free baling in heavy conditions is guaranteed. All bearings have central greasing, a Beka-Max
automatic bearing greasing system is optional. The rollers have built-in scrapers to push the material out and away from the bearings.
These design features result in the highest bale density in its segment.

Secure binding solutions

Nice tight bales on the field

Firm bale shape

One of the final steps in creating the perfect bale is the binding. It is one of the most crucial steps! The less time required to bind the bale, the higher the baling operation output. KUHN binding solutions guarantee reliable and secure net binding.
All FB models can be equipped with a combination of twine and net binding.

Excellent net spreading

The net binder with active stretch technology ensures a firm bale shape with constant net tension throughout the entire binding cycle. The net is fed into the front of the bale chamber to ensure it is taken by the bale immediately. A second net roll storage enables the operator to carry a sufficient net supply for long working days. Changing the net roll can be done easily whilst standing safely on the ground.
KUHN’s innovative design maintains constant net tension during the binding process. The net wrap system runs at 93% of the bale’s rotational speed to be able to stretch the net without breaking it. The pre-stretched net results in a bale that will hold its density. The net binding system spreads the net to the corners of the bale to prevent air pockets once the bale is wrapped, which will preserve the forage quality for longer.
Active stretch system

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
