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.

Unprecedented stalk chop quality when ROTO CROSS CUT technology is combined with 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. |

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 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.

Folding corn heads with or without stalk chopper |
1. The ROTO CROSS-CUT and ALUX corn heads are equipped with tempered aluminium alloy gearboxes.

Stalk rolls with 5 knives
Stalk chopper 
| (1) The ROTO CROSS-CUT corn head is equipped with tempered aluminium alloy gearboxes that enclose power transmission to the stalk rolls, the chains and the stalk chopper (if required). The steel gears undergo a treatment of carbonising, hardening and drawing, constantly lubricated in an oil bath. A characteristic addition is the modularity of the box, thus gaining in lightness and mechanical toughness. (2) The stalk rolls may be with 5 sharpened knifes (2A) or steel heat-treated (2B). (3) Each row unit is equipped with an independent adjustable clutch which protects it from overloads, thus avoiding breakages and ensuring safety and reliability under various harvesting conditions. (4) Hydraulically adjustable deck plates let you quickly adapt corn head performance to varying harvesting conditions. (5) The low power absorption stalk chopper mounted on each row unit is easily engaged and disengaged (6) in accordance with customer’s needs and without jeopardising the working of the head. A highly important mechanical note is the use, in each stalk chopper unit, of a free wheel which avoids overloads and heavy recoils, due to normal stops, acting on gears, shafts, bearings, with the advantage of an extended working life for the protected mechanical parts. |

The ROTO CROSS-CUT corn head can be supplied in the fixed 4 to 18 row version or the folding version from 5 to 16 rows. The driver opens and closes the head from the cab seat. The external overall dimensions of the folded head comes within the road-going size of a combine.
The ROTO CROSS-CUT corn head can be fit to any make and type of combine. |

 Lateral drive chains in oil bath also on folding frame |
|
|
Optional kit to harvest Light, tough frame structure with sections specially designed for the specific use. |
On request screws with hydraulic transmission can be applied to the side shields to facilitate harvesting in down crop conditions. | The low-profile row-unit shields facilitates harvesting in down crop conditions and can be lifted and secured to provide a complete access for easy inspection and servicing to the deck-plate area. |
