Comfort and efficiency

The well-received Comia line is being reinforced with two high-capacity harvesters. Models C10 and C12 will introduce even more harvesting efficiency and opportunities to the Comia line. In addition to impressive design, they also feature new technical solutions that are unprecedented in Sampo harvesters. Comia C10 and C12 represent modern harvester design and features, which are only available in Sampo harvesters. Wide tables, big grain tanks, large separator surfaces and especially effortless cleaning. The cabin’s operator ergonomics designed based on customer feedback results in pleasant harvesting.


Productive harvesting

Efficient cutting table for improved productivity

The cutting table of the Comia line is the result of years of careful design. As a result of thorough product development, table losses have been minimised.

Due to the patented pre-threshing system of the C12, you will achieve incomparable threshing results. Over 20% increase in overall productivity when compared to single drum models.


Subtle power

Same power, less fuel consumption

More power with less consumption. Comia C10 and C12 Agco Power engines fulfil even the most strict Tier 4 Final emission standards. There is ample power, up to 300 hp. The engines are economical and powerful.


Pioneer in cleaning

Market’s easiest and fastest combine to clean

Cleanest harvester on the market Sampo harvesters have always been well-known for their excellent cleanability. Comia C10 and C12 are no exceptions to this rule. The grain pan, sieves and walker bottoms can be cleaned in the field. Large side guards and centralised lubrication allow other servicing tasks to be carried out with ease.


Careful separation

High separation capacity in its size and class

Large walker areas combined with the CSP separation drum ensure maximum separation even in demanding threshing conditions. The new return cycle, equipped with a elevator, separates the returns to the start of the grain pan.


Advanced driving ergonomics

Single-hand control

The spacious Premium Plus cab offers unprecedented driving ergonomics in Sampo harvesters. The arm rest with integrated traction lever, all necessary harvesting controls and the new Comvision touch screen display all the necessary information.


Cutting table

Easy to connect, recognised for its geometrics and fully hydraulic features. These features are available in the Comia line C10 and C12 harvesters. The nylon/plastic tines of the pickup reel, which have been found to be effective, and the hydraulic header reverse put the finishing touches on this highly functional cutting table.

Thanks to years of careful design, whether the growth is tall or low, the Comia cutting table can easily handle it. The optimal distance from the knife to the feeder auger ensures uninterrupted feed to the machine’s feeder elevator. The machine also comes equipped standard with a handy lateral tilt feature. Cutting table widths begin from 4.5 metres and go all the way up to 6.3 metres.



The Comia line uses modern screw-on knife sections. In the event of a failure, you can easily replace a knife section. The knife is operated by a belt-driven Wobble Box drive. WB knife drive is almost maintenance free.

Feeder auger

The large diameter of the feeder auger prevents wrapping in even the most demanding conditions. In order to achieve even feed, the number of fingers have been increased according to the table width. When fingers are spread evenly across the entire auger, even peak loads will not cause problems. The feeder auger is equipped with a slip clutch, which is located on the pulley



Even efficiency with a pre-threshing cylinder The pre-threshing cylinder increases the efficiency of the machine without having to widen the machinery. Depending on the conditions, a C12 equipped with a pre-threshing cylinder is up to 20% more effective compared to a singlecylinder harvester. The pre-threshing cylinder significantly evens out the material flow to the main cylinder, enabling more efficient threshing. Under optimal conditions, up to 40% of threshing takes place at the pre-threshing cylinder. The resulting smoother threshing process notably reduces grain breakage.

The concave structure of Comia’s pre-threshing cylinder is patented. It differs from the competition, as the concave can be separately adjusted. The adjustment is conveniently completed from the cabin using an electric motor. In order to ensure the best results, a concave that is as precise of a thresher as the concave for the main thresher cylinder is located under the pre-threshing cylinder.


Grain pan

The grain pan grain surfaces of the Comia C10 and C12 are made of durable stainless steel. The grain pan surfaces will last practically forever. The stainless steel surface also has low friction, so it does not accumulate dirt. The surfaces can be easily removed for cleaning even when out on the field, using a tool included with the machine.

Shaker shoe


The counter impact shaker shoe effectively separates the grain from the chaff. At the same time, it results in much smoother running of the threshing machinery. As upper sieve is the modern RV2 lamella sieve type. On the RV2 lamella sieve, every other lamella is bent down. This efficiently prevents straw fragments from entering the grain tank. The lower sieve is the RV3 lamella sieve. Both sieve models, the RV2 and RV3, can be left more than 30% more open than a regular sieve without having unclean grain enter the grain tank. The sieves are both separately adjustable. The shaker shoe extension is also adjustable. Return system The new C10 and C12 include an unprecedented feature for separating returns. The returns are not taken to the thresher. Instead, they are taken through the re-thresher and are gently brought back into the machinery, almost below the concave. Instead of the traditional auger, the returns are transported to the re-thresher using a elevator. Due to the new structure, the grain pan is able to bring the re-threshed material to the shaker shoe in a controlled manner without interfering with the airflow of the fan. Fan and shaker sho e The large-diameter fan effectively blows to the shaker The speed of the fan can be conveniently adjusted from the cabin. The fan is also equipped with a handy bypass door, which can be opened if the fan effectiveness is to be reduced when, for example, threshing hay seeds.


CSP separation drum

If harvesting is performed in damp conditions or if the crop is green, high straw walker performance is essential. The CSP (Cylinder Separation) separation drum, located on top of the walkers, is designed to increase the separation capacity of the walkers. The effectiveness of the separation drum can be adjusted based on the different varieties. The most common grains are threshed using the basic settings, but when threshing oil plants, for example, it may be good to adjust the angle of the separation drum tines. The angle adjustment can be completed from the right side of the harvester, under the side guard. In Northern European harvesting conditions, the CSP separation drum achieves approximately a 20% efficiency increase at the walkers.



The cab is spacious, quiet and it has excellent visibility to the cutting table. In addition, it has excellent driving ergonomics. With these features, even long work days are completed with ease.

The controls have been positioned conveniently in the arm rest integrated into the seat. Starting the threshing machinery and cutting table is very easy using centrally located switches. All of the controls and switches necessary during harvesting have been carefully positioned in the same location, the arm rest. The traction lever is used to control the driving direction and speed of the combine. All of the controls of the cutting table are also located on the traction lever. Even turning the unloading pipe is conveniently completed using the switches on the traction lever. The controls that are not needed most of the time are located on the right side of the cab. They include, for example, the concave cleareness adjustment range, grain tank elevation and header reverse. Warning indicators are located on the column on the right. An audible tone will be emitted in the event of a hazardous situation.

Due to the low noise level in the cabin, a hands-free system is included as standard with the combine. You can connect your phone via Bluetooth.


Comvision – all in one package

A real information centre has been fitted in the cabin’s right column. Using the Comvision display, you can see all the necessary information on the combine and the engine. The Comvision colour display is more than a mere display. It is a combination of an operating computer, loss indicator and engine indicator display. It will also display potential warnings from the threshing machinery. The system also includes area measurement. Other features include, for example, automation of the pick-up reel. If you want the pick-up reel to rotate slower or faster than the operating speed, you can adjust it using the Comvision display. As the Comvision display is a touch screen display, you can calibrate the thresher loss indicator with it. You can determine the basic view. A the top of the screen, you can select four different types of rotation or speed indicators. The display is conveniently located by the traction lever within easy reach.


Grain Tank

The grain tank becoming full is always a good thing, even if it means that harvesting is interrupted. It means pay day for the farmer. The Comia C10 and C12 are equipped with large grain tanks. Sizes range from 6,500 litres to 8,100 litres, depending on the grain tank model. The tanks are equipped with two level guards, the position of which can be adjustable when necessary. The tank is also equipped with a light, and the inside of the tank can be monitored from the cab through a large window. The top of the tank is solid, but it is lifted for harvesting, which allows the full capacity of the tank to be utilised. The top of the tank is lifted by the press of a button from the cabin, which engages two electric motors that lift it up. Harvesting is also possible with the grain tank at transport height



The emission standards of diesel engines are constantly becoming stricter. The Sampo Comia C10 and C12 fulfil the Tier 4 Final emission requirements of commercial machinery. Using the new SCR diesel technology, you preserve the environment and save 10% in fuel costs, when compared with Common Rail fuel systems. The exhaust gases of the engine are treated with AdBlue. Using the Comvision display in the cab, you can monitor the consumption of the additive.


Cleaning and Maintenance

The undisputed leader on the harvester market with regards to cleanability. One needs to only study this spread to ensure the accuracy of this statement. Sampo-Rosenlew harvesters have always been easy to clean, due to technical solutions. The grain pan segments can be extracted, straw walker bottoms can be removed, and so on. 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 save time. The top axle of the feeder elevator and the threshing concave is easily accessible. By removing the large service doors, you can blow the threshing concave clean, if necessary, and if you have operated in difficult conditions. The rule of thumb is that a clean harvester will produce clean grain.
