The OptiFeed rotor design, where rotor tines - made out of Hardox® wear plate - and auger function are combined on one shaft, helps even out the swath by spreading the crop evenly for consistent bales every time. When crop cutting is not required, the OptiFeed system ensures a controlled and consistent crop flow to the pre-chamber. With the rotor, an additional level of protection is added to the machine.

The 60 cm diameter Biomass OptiFeed rotor design combines all the benefits of the standard OptiFeed rotor with boltable rotor tines made out of Hardox® wear plate for excellent durability and easy exchange. These rotor tines are specially designed for aggressive energy crops such as sugar cane leaves.

The OmniCut cutting systems are designed for unlimited intake capacity. There are two different types of OC cutting system (availability dependent on BigMaster model):

OC 15
The OC 15 offers a cutting length of 45 mm. The patented rotor tine shape ensures a low power requirement and a perfect cutting quality. The knives, individually protected with a spring, can be changed easily with the standard cassette system.

OC 23
The OC 23 offers a cutting length of 45 mm on the 120 cm wide channel models. With a rotor diameter of 60 cm, the OmniCut rotor will process every swath that is placed in front of the baler. The knives on the OC 23 have individual hydraulic protection. This ensures a perfect cutting quality regardless of working speed and crop.
On the BIGMASTER 6 models the operation of the knife group configuration is easily done from the tractor cab via the terminal. 
The operator can easily choose from the following knife group configurations: 0 – 11 – 12 – 23. The boltable rotor tines made out of Hardox® wear plate guarantee easy exchange. Together with the standard cassette system for easy knife changing, you not only invest in cutting quality but, above all, in driver comfort.

Whether you are baling dry straw, hay or wet silage, the POWER FEED ROLLER allows you to take capacity to the next level. Difficult crop conditions or inconsistent swaths could pose a challenge for an intake rotor. With the POWER FEED ROLLER this belongs to the past. This driven crop roller actively follows the height of the swath. As a result, the crop is slightly compressed and evenly distributed when entering the intake rotor. Inconsistencies in the crop flow are smoothed out, delivering a steady crop flow towards the rotor.

DEUTZ-FAHR's engineering excellence is evident in pistons and a compression chamber designed with the primary goal of producing extremely compact, tightly packed bales. The 3.4 meter long compression chamber ensures outstanding bale density. The piston is driven at a speed of 46 strokes/minute directly by the main transmission and is mounted on three or four 150 mm diameter roller bearings which run on specially treated slides. The roller bearings are lubricated by a centralised system and located outside the compression chamber for easy access for inspection and maintenance. The pressure may be preset directly from the cab of the tractor. In the event of overload, the machine reduces the pressure in the chamber to prevent the risk of damage. Once the overload has been cleared, the preset pressure is restored. All models are equipped with cam-actuated clutch protection systems for all the main feeder elements: namely, the pick-up, integral rotor and loader fork.

The patented torque regulation system on all BigMaster 6 series 120 cm bale channel models ensures a perfect balance between capacity and density. The system consists of plunger rod load pins that measure the plunger force and an angle sensor that measures the crank angle. Throughout the complete plunger cycle the exact torque is calculated. The benefit of this sophisticated measuring method is that up to 5% higher bale density can be achieved when driving at a capacity of 25 t/h. This results in a higher transport and handling efficiency.
