Great news guys (writes Brian Weatherley) Corn harvesting in
Harald Bruhns chose the Zetros as the vehicle chassis because it has a flexible, robust body and a chassis which can be adjusted for off-road operation and Reyk continues:”We immediately decided on the Allison automatic when we came to the transmission choice because it has the essential advantage of powershifting. This means traction is continuous without power interrupts, which is a mandatory requirement for our application. During gear changes with a conventional dry slipping clutch under heavy load and terrain conditions, the vehicle gets stuck, and starting it again is very difficult.”
Fortunately the Allison torque converter is not a wear component and ensures coupling with the engine without the need of a dry clutch. It delivers torque multiplication and superior startability while reducing driveline stress and wear. So for Reyk Wernicke the choice of transmission was the right one “The handling of the Allison transmission is really easy. When we present it to farms, the drivers are excited because the transmission is so easy to handle, and the driving comfort is very high.”
The Secutor is available with a 54 m³ silage-body from SGT or can be used as a liquid manure tanker (up to 28 m³). Even sprayer and fertilizer spreader bodies are possible. All in all, a total weight of up to 40 tonnes is allowed. And now read on for the full details!
Secutor versus tractor: Comparative test of the
During the corn harvest in 2010, the Secutor was working beside farm tractors where its potential was proven. This was even scientifically tested last November by the
Remodelling Zetros to Secutor
During the transformation from Zetros to Secutor, several enhancements were implemented by Harald Bruhns GmbH. All were approved by Mercedes-Benz, meaning that the Secutor can be maintained and repaired in all Mercedes-Benz garages. The wheelbase was shortened to 4200 mm, to improve manoeuvrability. Additionally, stronger rear axles with increased springs were mounted. The large-volume implement tires provide optimal protection from the ground and traction at a vehicle-outside-width of 2.75 m (front axle 560/60R22.5, rear axle 600/55R22.5). The construction of a bowl clutch as a connection to the trailer enables optimal cross-country mobility by a 13° swing angle. In addition, a powerful hydraulic system was mounted with 140 litres/min pump performance at 200 bar and includes a hydraulic tank with 200 litres with an oil cooler at the cab backside. It is controlled by an ISO Bus controller. In September, the first Secutor was placed on German farmland in support of the 2011 corn harvest
