Let's play big!

This year, AGCO will present at the Agrosalon 2012 international agricultural exhibition a new series of Challenger RoGator 1100 self-propelled sprayers designed expressly for Russian agricultural enterprises.

Series 1100 machines have an operating fluid tank with a volume of 4,200 litres and are fitted with booms with grip widths of 30.5 and 36.5 metres. Booms with a section folding mechanism are adjustable in height relative to the soil surface. They feature the Autoboom automatic levelling system which keeps them level regardless of the changing terrain relief and vegetation height.

Thanks to hydraulically regulated wheel spacing within 3.05 to 3.86 m and to a clearance of 130 cm, the RoGator can treat the broadest selection of crops.

The new sprayers are multirole machines suitable for introducing both liquid chemicals and granulated mineral fertilisers. For the first time, a new AGCO Power engine was installed on the self-propelled sprayers, cutting fuel consumption by 6%. Combined with a seven-step transmission and improved drive, the AGCO Power unit ensures greater power transmission to the wheels and higher efficiency even under the most adverse conditions. The pneumatic suspension and the C-shaped flexible frame provides maximum smoothness on the move and a higher operating speed.

“The new machines are fitted with a cutting edge spraying system that is like nothing else in the world”, says Dmitry Trofimov, AGCO product manager. “High spraying precision is achieved due to the operating fluid being delivered in adjacent sprayers with a pressure difference of only 0.07 bar even on the longest boom with a grip width of 36.5 m”.

This becomes possible thanks to the latest engineering developments. The Challenger RoGator machines are fitted with an operating fluid delivery pump driven by a hydraulic motor and regulated by a pulse width modulation-operated valve. This type of design allows for quick adjustment of the pump output depending on the spraying speed and introduction rate, all of which reduces the risk of excessive or insufficient chemical input.

The pipelines mounted on the sprayers have no acute angles and narrowed portions. Accordingly, the operating fluid is delivered smoothly. During the operation, the boom pipeline's pneumatic cleaning system ensures minimum loss of time during chemical replacement.

The treble air filtration and positive pressure preclude the entry of chemicals into the cabin, thereby assuring maximum operator safety. The automatic air temperature control system in the cabin and the viewing capability, the best in its class, provide maximum comfort for the operator. The spraying control unit, RoGator Management Centre, enables the operator to control the various machine functions and to obtain, by means of the sensor display, the information he needs concerning the operation of all systems.
