This quick reference guide has been produced to aid operators with familiarisation and settings for the CLAAS AVERO combines. CLAAS combines are designed for output and efficiency but this can only be achieved with correct operation and maintenance of the machine.
Safety Safety is of the utmost importance whilst you are operating and maintaining your combine harvester. Make sure that all of the risks are assessed to reduce the likelihood of an accident. Make sure you are familiar with the controls and operation of the machine and have read the operators manual The combine harvester has many moving parts, guards are designed to keep you safe, please ensure that all guards are kept in place and in good condition when...

AUTO CONTOUR Cutting height control Cutting height The cutting height is displayed above the bar (A) between the numbers 100 and 55. (Numbers are only for illustration use and are not on the Combine) 100 = Cutterbar skids do not touch the ground and the sensing bars are fully swung out.
Page 11
AUTO CONTOUR Pre-set cutting height control Cutting height pre-selection The cutting height pre-selection ensures the cutting height stays constant with the machine, it measures the position of the trunking and not the Cutterbar sensing bars. The cutting height is displayed using black bars between 100 and 0.
Page 12
Setting and adjusting the cutting height Saving the cutting height / ground pressure • Drive into the crop with the threshing and cutterbar engaged. • Press button (1d) briefly, the cutting height control menu (2) is active. One of the black bars (3) will be active, to change to the other press button (1d) briefly again.
Page 13
Setting and adjusting the cutting height Adjusting the cutting height, ground pressure or pre-set cutting height While driving it is possible to adjust the cutting height / ground pressure from a pre- set position using 2 methods. 1. Use buttons (1a) (1b) to adjust the height and then press and hold button (1d) or (1c) for 3 seconds and a buzzer will sound to indicate the new value has been saved.
Carrying out Adjustments For machine field settings refer to the relevant section of the Operators Manual, this section offers a quick guide on how to adjust the machine settings Concave adjustment – do not adjust during threshing! Use the lever (H) for simultaneously adjusting the distances between the pre-concave and the accelerator and also between the main concave and the threshing drum.

Lifters It is recommended that lifters should be fitted to CLAAS cutterbars. The lifters should be fitted by placing the first one on the fifth finger from the RHS of the cutterbar and then on every fourth one thereafter.
Combine Adjustments - Cutterbar Knife Check that the knife is in good condition in order for it to work effectively. This involves replacing damaged or broken sections, removing vertical movement by adjusting the keeps and making sure that the fingers are not rounded or bent. Regular checks/adjustments will aid cleaner cutting and reduced stress on the knife drive system.

Combine Adjustments - Cutterbar Skids The skids underneath the cutterbar should be set to suit the local conditions i.e stones, loose soil, etc. It is recommended that they are lifted right up in abrasive conditions. VARIO (if fitted) VARIO cutterbars allow the operator to vary the position of the knife to suit different crop conditions.
Threshing To obtain initial settings it is recommended that the suggested settings within the Operators Manual are used, these are to only be used as a starting point, then adjustments should be made from there. Often changing one thing can change another. Only make one adjustment at a time.

Pre-Separation De-awning On the AVERO 240 the de-awning can be carried out by operating the lever (1), by the right hand front wheel of the machine into position (A), which in turn installs a set of plates under the APS concave. This gives the crop an extra ‘rub’ which in turn threshes it harder.
Separation Approximately 90% of of the grain needs to be separated by the time the crop leaves the drum. This means that the remaining 10% has to be separated by the straw walkers. Straw curtain As the crop leaves the beater a straw retarding curtain is fitted to control the throw of the material on the walkers.
Cleaning Preparation pan The preparation pan is the first part of the cleaning system that the grain will come into contact with. It’s function is to separate the grain and the chaff. The grain is heavier and therefore goes to the bottom, the lighter chaff goes to the top. It is important that this is kept clean, to allow this to happen effectively.

Cleaning Sieve adjustment Lever (3) is used to adjust the upper frogmouth sieve over its full length, the returns pass through area (2). Lever (4) is used to adjust only the returns pass through area (2). – Always set the returns sieving area (2) of the upper frogmouth sieve with lever (3) for all crop types wider than the grain sieving (1).
Page 25
Cleaning Returns The returns should be monitored regularly both in terms of volume and composition. By looking through the window (1) on the lower RHS of the drivers seat, the returns can be seen. The centre tube of the auger should always be visible.
Loss calculations The following information regarding losses is taken from a narrow bodied Claas Tucano not a Avero and is therefore not an exact guide to your losses it is a rough guide. The number shown represents the grain per meter squared at 1% grain loss –...
When checking belt tensions there are two main types of tensioner that are fitted to AVERO Combines 1. End to guides – Correct tension is achieved when the ends of “D” are end to end.
Wet harvest recommendations With wet and laid crops, it is even more important to get a good cut and feed into the combine. Check the knife and fingers regularly, paying particular attention to the knife to finger gap (keep adjustment). To allow the cutterbar close to the ground when picking up laid crops, the skids under the bar must be raised into their highest position.
Page 33
Wet harvest recommendations Some dirt can usually be removed from both the cross auger covers, and the bottom covers on both the clean grain and returns elevators. When unloading wet grain, reduce the flow into the unloading auger by shutting down the slides on both the cross augers in the grain tank.
