• Minimum of 4 de-awning bars, laterally insertable

• Quick concave-to-drum gap adjustment operable from the operator’s seat

Straw Beater

• Multi-part straw turning drum (straw beater) with loosening elements for optimum grain separation

Cleaning System

• Multi-step surface shaker with minimum 1.8 m² separation surface

• Shaker shall include a quick-change mechanism allowing the shaker to be removed and replaced within 5 minutes for rapid field cleaning

• Double sieve system with minimum 2.0 m² cleaning surface, including:

◦ One adjustable lamella top sieve

◦ Minimum of two bottom sieves (round hole, including at least 10 mm and 12 mm diameter)

• Hydraulically driven, steplessly adjustable cleaning fan (wind), operable from operator’s seat with digital rpm readout

• Fan capable of rapid high-speed blowout of sieve unit for between-plot cleaning

• Fan shall be capable of complete shutoff (zero airflow) while the machine is combining, to accommodate very light or fine seed crops

Grain Transport and Collection/Bagging Unit

• Pneumatic grain conveyor system by high-performance turbine; system shall be seed-tight with no leakage

• Sieve case with double injection sluice

• Bagging unit with a minimum of two outlets and a platform for bags for the collection of individual plot samples

Grain Tank

• Minimum grain tank capacity of 700 liters (20 bu)

• Manually foldable unloading auger

• Unloading height of at least 2.60 m

• Grain tank shall hydraulically tilt to the rear of the machine to allow complete, mix-free cleanout between plots

• Cleanout tray or equivalent collection point below the grain tank auger to capture residual seed during cleanout

• Filling level indicator visible to operator

Cleanout and Cross-Contamination Prevention

• All interior seams, gaps, and corners of the threshing, separating, and cleaning areas shall be sealed with silicone or equivalent sealant, both inside and outside the machine.

• Rubber gaskets or equivalent seals shall be installed along all access panel gaps and covers to prevent seed or debris from lodging.

• Interior surfaces of the threshing and separating chamber shall be painted white to facilitate visual inspection for crop contamination and residual seed between plots.

• Engine covers shall be easily removable without tools or with minimal tooling to allow safe access for servicing and field cleaning.

• Front and rear axles shall have covers or guards to prevent the accumulation of straw and seed around drivetrain components.

• Spacers shall be installed between hydraulic lines and hoses routed through the machine to prevent seed and straw from accumulating between lines.

• Machine shall be equipped with a combine-powered air compressor with a minimum 10-gallon (38-liter) air tank and a minimum 40 feet (12 m) of air hose, enabling whole-machine cleanout in the field without an external power source.

• The machine shall utilize hydraulic drives to the maximum extent practicable to minimize the number of drive belts. The total number of drive belts shall not exceed five (5) to reduce maintenance downtime and seed trap points.

• Pneumatic grain delivery system shall guarantee seed-tight transport with no seed leakage between the threshing area and the collection point.
