Unprecedented, simple and unique ROTO
DUAL stalk cross cut technology plus unsurpassed
DUAL speed system
•  Allows stalk to decompose better over the winter.
•  Integrated horizontally parallel knife roll technology and additional unique vertically radial multiblades system processes and prepares the stalk to decompose easier and faster.
•  Optimizes the pre-cut process
•  Optimizes the harvest process
•  Causes less shaking of the stalk
•  Less residues in combine
•  Fastest field travel speeds
•  Low horsepower required
•  Engineered for customers who demand unprecedented top aggressive residue processing with low additional investment
•  Tremendous low cost maintenance by reversible ROTO CROSS CUT knives.
HOW IT WORKS
ROTO CROSS CUT system delivers a unique crossed and continuous partial cut of the stalks.
In each row over 100 radial knives interact with 10 axial knives during forward motion to partial cut the stalk both horizontally and vertically with a crossed and continuous partial cut that is axial and radial at the same time.
The speed S1 pulls the stalk downwards by 10 horizontal knives per row, with the lowest peripheral speed in the market with a minimum impact for corncobs, optimizing the harvest.
To improve stalks decomposition the speed S2, higher than stalk speed S1, makes a vertically partial cut of the stalks by the over 100 radial blades per row.
To optimize the harvest process the blades are specifically designed to catch the stalk in many opposite points at the same time thus causing less shaking than the traditional blade rolls, less stalks inside the combine and a higher harvest speed.
ROTO CROSS CUT slices the stalk vertically to get better decomposition
Unprecedented stalk chop quality when ROTO CROSS CUT technology is combined with stalk chopper.
STALK CHOPPER   
A highly important mechanical note is the use,
in each stalk chopper unit, of a free wheel
which avoids overloads and heavy recoils.
The 2 rotating blades stalk chopper can be
engaged or disengaged (ON / OFF).
The forward position of stalk choppers covers
100% of the rolls’ pulling area. This system
assures an optimal chop of the stalks, which pass from the rolls directly to the working area of the chopper.
1. The ROTO CROSS-CUT and ALUX corn heads are equipped with tempered aluminium alloy gearboxes.

3. Each row unit is equipped with an independent adjustable clutch which protects it from overloads.

4. Hydraulically adjustable deck plates.

5.
The low power absorption stalk chopper mounted on each row unit is easily engaged and disengaged
(ON / OFF)
.
 
6. A highly important mechanical note is the use, in each stalk chopper unit, of a free wheel which avoids overloads and heavy recoils.
2. CRESSONI basic stalk rolls with 5 knives
•  The best stalk precut, to obtain the best stalk-chopping quality in the market with parallel knife roll technology
•  Larger diameter, higher speed and lower RPM for better stalk pulling than old style rolls in the market.
The forward position of the stalk choppers covers 100% of the rolls’ pulling area. This system assures an optimal chop of the stalks, which pass from the rolls directly to the working area of the chopper. The working areas of the rolls and the choppers fully correspond and are overlapped, and therefore allow the chopping of the entire stalk’s length in small pieces-starting at a minimum safety distance of 3 inches from the ground.
Lateral drive chains lubricated in oil bath.
