KUHN FC 3125 DF, 3525 DF, and 3525 RF front mounted disc mower conditioners set a new level of reliability and durability in the market. These mower conditioners feature an attractive, functionally designed headstock that offers exceptional terrain following, flexible enough to adapt to any terrain changes encountered in the field. The compact frame, shaped like a hammerhead shark, offers improved visibility for the operator. These machines feature the heavy-duty Optidisc^® Elite cutterbar utilizing a through-bolted design and lubed-for life technology, which guarantees minimal maintenance and maximized cutting efficiency. The ability to vary conditioning intensity to match harvesting windows is assured with the use of the 2-Speed DigiDry^® finger conditioner and Diamond Block^® rubber roller conditioner. Lift-Control^® hydropneumatic suspension limits ash incorporation and greatly improves compensating for immovable field obstacles. Protectadrive^® safety provides maximum reliability and quick service, and the Fast-Fit^® knife system allows you to quickly change out the knives with the use of a simple tool. For even greater productivity, pair a KUHN FC 25 F Series front mounted mower conditioner with a KUHN FC 30 Series rear mounted mower conditioner for the ultimate triple mower conditioner combination. The total combined working width, of up to 32’6”, knocks down large fields in no time, while exclusive features provide strong returns on investment by reducing maintenance and downtime.

The Optidisc^® Elite Cutterbar: A Clean and Consistent Cut

Lubed-For-Life Optidisc^® Elite Cutterbar

The Optidisc^® Elite cutterbar provides a flat, streamlined profile so that soil and crop residue do not accumulate and material flows smoothly, even in heavy, difficult crop conditions. These mowers come standard with the Fast-Fit^® quick release knife system. Optidisc Elite cutterbars are designed and tested with a zero oil change interval. The highly-polished gears and synthetic gear oil ensure that this system does not require any regular internal maintenance, eliminating the need for cutterbar oil changes throughout the life of the machine.

Differential Disc Spacing

The innovative design of the Optidisc Elite cutterbar offers exclusive differential disc spacing.

Less Distance for a Clean Cut - Narrower spacing at diverging discs provides greater knife overlap, which results in a clean cut, even when the grass is short or light.
More Distance for Easy Crop Passage - Wider spacing at converging discs provides more space for the crop to pass. Cut crop is quickly carried away from the cutting area, greatly improving the cut quality.

Standard Fast-Fit^® Knives

The Fast-Fit^® quick-release knife system allows an operator to rapidly change out cutting knives with the use of a simple tool, yet still retain optimum cut quality and knife life. With Fast-Fit, an operator can achieve up to 50% time savings over a standard system.

Protectadrive^® Disc Bearing Stations

Protectadrive® Safety: Every minute saved during the hay season is precious. Ultimate protection, from the externally removable Protectadrive disc bearing stations, provides maximum reliability and quick service. In the event of an impact between a disc and an obstacle, the shaft holding the disc can shear just above the bearing. This is thanks to its carefully dimensioned shear groove. As a result, the gear teeth are protected.
Extra Rigidity Where it Counts: Disc bearing stations are attached by bolts that pass through the entire cutterbar. This is an exceptionally strong and secure attachment with no risk of mount being torn out of the cutterbar in case of shocks. The disc drive pinion is held precisely in place, all resulting in excellent reliability and reduced maintenance costs.
Gear-to-Gear Power Transmission: Gear-to-gear power transmission, a staple of all KUHN disc mowers, allows for maximum power to be transferred through all gears in the cutterbar. Unlike other gear cutterbars, equal sized gears throughout reduces torque on the gear teeth and leads to unsurpassed reliability and longevity.

Easily Adjustable Overlap

For a clean cut on slopes and bends, the overlap between the front and rear units can be adjusted hydraulically between 12” and 18” (depending on the model combination) – even while driving. This is a real benefit for tractors with wide wheel spacing or large wheels.

Exceptional Ground Adaptation and Maneuverability

Superior Ground Adaptation

Front mowing units have to remain flexible enough to smoothly adapt to any terrain changes they may encounter. At the same time, they are often subject to higher stress. The KUHN front mount mowers are designed for this purpose, they feature a pendulum-type articulation of the mowing unit and significant adaptability characteristics. They can oscillate left to right at an angle of up to 30° and cover a vertical travel range of 27.5”.

Lift-Control Hydropneumatic Suspension

Lift-Control is much more than just a suspension system with a nitrogen accumulator replacing the traditional spring. The main advantage of the Lift-Control system is derived from the exclusive way in which kinetic forces that act on the cutterbar are utilized. KUHN engineers have succeeded in making a dynamic suspension system, as opposed to the passive system most commonly used.
With the Lift-Control system, as the force exerted on the cutterbar increases, the suspension system automatically lightens the cutterbar. The greater the force, the lighter the cutterbar.
Benefits include:

Constant ground pressure
Non-stop safety breakaway
Excellent terrain following
Less soil in the crop
Minimize torn up turf

Uniform Crop Conditioning

DigiDry^® Finger Conditioner

The DigiDry^® finger conditioner provides consistent drying of grass and legume crops in various conditions with little maintenance. Wide rotor, fingerstyle conditioning increase crop-on-crop rubbing to strip off the waxy cuticle helping the steams dry at the same rate as the leaves. The built-in breakback feature normally protects against damage from rock and other foreign materials.

Diamond Block^® Conditioning

Diamond Block^® conditioning rollers stand out from the competition as the only rubber roller set designed exclusively for a disc mower. The horizontal staggered diamond pattern gives more points for the crop to be crimped as it flows off the disc at an angle. Adjustment of the roll pressure and roll gap is simple and can be done quickly in the field.

Direct Drive Design

The direct drive design to the conditioner provides easy access for servicing and fully eliminates belts. Reliability is greatly improved when working in longer crops such as ryegrass.

Built-In Rotor Protection

To help prevent damage to the conditioner gearbox in the unlikely event of an overload or ingestion of a large foreign object, the shear bolt hub allows the operator to clear the obstruction from the conditioner, quickly rotate the inner hub into position, install the new shear bolt and return to mowing.

Equipment

FlexProtect™ Side Shields

On encountering an obstacle, the KUHN FlexProtect™ side covers bend without breaking or damaging the mower. After the obstacle’s passage, the side shields automatically returns back to its original shape.

Crop Lifters

Recommended only for sorghum or other hard feeding crops.

Work Lights (Front Mount Models Only)

For added light when moving at night.

HD Knives

Available through KUHN Parts, the HD knives provide increased longevity and durability when mowing in rocky and other difficult conditions.
