A SAMPO ROSENLEW hybrid model, in which straw walkers have been replaced with two rotors. Over 30% more threshing efficiency when compared to the C12 model.Watch video
Combining the best elements of known threshing technology’s, the harvester will be called a Hybrid. The C22 2ROTO, is equipped with a TS front cylinder system and two rotors, is the most efficient harvester of the COMIA range. The harvester, has large separator surfaces, has two opposite spinning rotors that make the harvester more than 30% more capacity than a similar-sized straw walker machine. Threshing is achieved in the traditional way, but the rotors add separation capacity.
The modern AVARA cab finishes off this harvester and ensures comfort during a long day of threshing. The cab is quiet and its features and controls are in a class of their own.
AVARA - style and functionality
Eight work lights, modern LED headlights, and a wide windscreen. One of the factors considered during the design of the cab, was the driver’s clear visibility of the cutting header. The harvesters of the COMIA series have a multi-function drive handle, and the layout of the other controls has also been carefully designed. All threshing-related activities, such as the controls of the machinery and cutting header, are located in the armrest. The console also has 12V and USB connectors. You can easily control the modern COMVISION II touchscreen with one hand while harvesting. It is very easy to monitor threshing, when at the same time you can see e.g., the grain loss monitor, height of cutting header, speed, and warning lights. Any alarms can be seen on the COMVISION II screen as pop-up warnings, and the system also gives out an audible signal.
Excellent cutting headers
Easy to connect, recognised for its geometrics, and fully hydraulic operations. The nylon/plastic tines of the pick-up reel, which have been found to be effective, and the hydraulic header reverse put the finishing touches on this highly functional cutting table. Whether growth is high or low, Comia’s cutting header, which has been developed over several years, can handle it. The optimal distance from the knife to the feeder auger ensures uninterrupted feed to the machine's feeder elevator. Side tilt and distance height control come as standard. The widest header is 6.9 metres and it has a feeder auger with chain drive.
2Roto, two threshing cylinders, two rotors
The hybrid threshing mechanism of the COMIA C22 2Roto is based on the C12 model. The biggest difference is that the straw walkers have been replaced with two rotors. These two rotors spinning opposite each other raise the threshing efficiency by more than 30%. The rotors are fed through the rear beater from above. Threshing itself is performed using the familiar TS double cylinder system. The efficiency of the fan and the grain elevator has been improved significantly and the drive capacity of the cylinder variators has been increased. The system automatically tightens the belt more as the load gets bigger. The RV2 lamella upper sieve efficiently removes chaff and the RV3 lower lamella sieve sieves clean grain into the tank, like in the other combine harvesters of the COMIA range.
Power and durability
Every combine harvester of the COMIA-series has a strong three-gear gearbox. The gearbox has a hydraulic clutch assist, which makes shifting easy and handy. In order to activate the clutch assist, you simply press a button on the gear stick. The gearbox is powered by a strong hydraulic motor, which can be controlled continuously from the cab using the drive handle. A strong front axle equipped with final drives and disc brakes, allowing for the use of wide tiress. Optionally, the COMIA can be equipped with extra wide tiress. You can check from the specifications, which tiress go with your COMIA. Hydraulic four-wheel drive, which helps driving in tough conditions, is available as an optional extra.
The undisputed leader on the market with regards to cleanability
Thanks to their technical solutions, the Sampo-Rosenlew combine harvesters have always been easy to clean. For example, the grain pan sections can be extracted and the straw walker bottoms can be removed. Although the same features may be included in other makes, Sampo has implemented them so that you do not have to carry out cleaning in your service area. Instead, you can clean them on the field and have more uptime.
The bigger the tank, the greater the efficiency
The COMIA C22 has been equipped with a 7,600 litre grain tank. When threshing, the lid of the grain tank must be lifted, but this is easily done electrically from the cab. The unloading speed is a whopping 100 l/s and the unloading height is 4.4 metres. The length of the unloading pipe is also sufficient, even with a wider cutting table. The long unloading pipe can easily be swung by pressing a button on the drive handle. Unloading is also started from the drive handle. A large grain tank window allows easy monitoring of the filling of the tank. The tank is illuminated with a powerful LED light. This way you can monitor the grain quality also at night. The filling alarm of the tank is connected to the COMVISION II screen, and it lets you know when the time comes to empty it.
