Central Alberta Hay Center

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

1. 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.
2. More Distance for Easy Crop Passage – Wider spacing (2) 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.

• 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.

The cutting discs and end cones provide high crop lift, allowing cut materials to quickly leave the cutterbar and enter the conditioner, especially in thick crop conditions.

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.

Unlike competitive models that require daily greasing, the drive shaft to the cutterbar uses maintenance-free U-joints. These joints reduce overall maintenance and eliminate excessive wear from improper maintenance.

The main gearbox is the core of the unit, specially built by KUHN to efficiently and reliably transfer power to the cutterbar and conditioner. The direct drive eliminates periodic checks on belt tightness and wear.

This maintenance-free system allows the machine to quickly adapt to abrupt changes in terrain or when an obstruction is encountered in the field. The cutting head is able to move up and back simultaneously, dissipating the force of any impact and providing space to clear the obstacle.

The header is suspended on each side by a long, large-diameter spring that provides a constant range of flotation. A slotted link allows the head to move, eliminating the need to run the tractor hydraulic valve in the float position. The floating head lifts up and back, and oscillates from side to side, to closely follow ground contours and conform to irregular terrain. This reduces the amount of missed crop in the field and helps keep dirt out of harvested crop.

The heavy-duty Gyrodine® gearbox is designed to withstand the most severe pull-through force from the hitch to the machine. The swivel design allows turns in excess of 90° while keeping the PTO driveline straight. This design allows extremely tight turns for clean, square corners while minimizing PTO vibration and wear.

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.

The DoubleCrimp™ steel roller design provides consistent crimping and even feeding of thicker crops and extended life in difficult and abrasive conditions. The steel construction allows for a longer wearing life and achieves thorough conditioning of more delicate crops like alfalfa. Adjustment of the roll pressure and roll gap is simple and can be done quickly in the field.
