New engines for AVERO combine harvesters

0

The AVERO combine harvester has been fitted with a new engine that enables it to comply with the Stage V emission standard. In addition, the revised layout of the emission control equipment in the engine compartment improves access for maintenance.

The AVERO 240 is now equipped with a new engine, the Cummins B6.7. With a displacement of 6.7 litres, it develops 213 hp, which compared with the predecessor models represents an increase in output of 8 hp. Compliance with the Stage V emission standard is achieved by means of SCR and DPF technology with a urea tank capacity of 49 litres and without the need for exhaust gas recirculation.

The exhaust gas aftertreatment system for the new engine takes up significantly less space. As a result, the accessibility for maintenance is improved. Externally, this change is reflected in the reduced height of the engine cover, which is now at the same level as the closed grain tank.

The AVERO 240 is equipped with the APS threshing system, the key benefits of which include high crop acceleration and the ability to separate up to 30% of the grains in a preconcave. This means up to 20% greater throughput for the same fuel consumption.

Residual grain separation in the AVERO 240 is performed by four straw walkers with four steps. Using agitator tines, the intensive separation system is able to handle even large volumes of straw and ensures maximum separation of the residual grains.

A large grain tank is another factor which increases productivity. The grain tank volume is 5,600 litres. The unloading time is less than two minutes. The operator has a good view of the grain tank and grain sampling can be performed easily. An inspection window in the cab allows the returns to be checked directly.

The AVERO uses the same cutterbar mount interface as the LEXION, featuring a central multicoupler, a practical central locking system and protective front attachment suspension.

This allows all CLAAS standard cutterbars from the CERIO C660 to the C370 to be mounted, as well as the VARIO V540 or V600 cutterbar. A notable advantage of VARIO cutterbars is the speed with which they can be converted from harvesting cereals to rapeseed.

A spacious and ergonomic cab makes for a less strenuous working day in the AVERO 240. From setting the cutterbar and adjusting the threshing concave to checking the returns – the entire combine harvester can be controlled and monitored from the cab.

All this is performed by means of user-friendly controls, such as the multifunction lever and the adjustable steering column. The CLAAS INFORMATION SYSTEM (CIS) keeps the operator informed about key machine data from the fuel level and temperature display to figures for the throughput speed, fan speed and threshing drum speed.
