Claas: Wider cutterbar to boost Lexion 600 performance Published on August 14, 2009 Despite
last year’s difficult harvesting conditions, analysis of the Telematics data
showed that many Lexion 600s using 10.5m cutterbars consistently achieved
average throughputs in excess of 60t/hr with peaks of more than 100t/hr. As on the
smaller V1050, the new V1200 cutterbar features a split reel and auger,
supported on a central bearing. However, due to the width of the new cutterbar,
the flexible knife bar has also been split. In place of the belt drive used on
smaller cutterbars, the knives on the V1200 are powered by dual synchronised gear
drives on each side of the cutterbar. This ensures operational quietness and
requires minimal maintenance. In addition, the cutting frequency has been
increased from 1,120 strokes/minute to 1,334 strokes/minute. As on all
other Vario cutterbars, the distance between the knife and the intake auger can
be varied from 48cm to 78cm while on the move, which can help improve crop flow
by up to 10%, and the new mechanical drive system incorporates telescopic
shafts to accommodate this. For oilseed rape, by using infill plates and a
longer drive shaft, the distance can be further extended to 108cm. The intake
auger itself has also been enlarged to 660mm diameter (580mm on the Vario
V1050) for greater stability and to provide greater uniformity of the increased
crop matter being handled. The reel
runs on patented polymer shaft bearings and features crescent shaped reel tine
arms designed to eliminate crop wrapping and so reduce harvest losses. The
cutterbar is designed so that oilseed rape side-knives can be quickly and
easily mounted, and is equipped with a hydraulic pump with quick release
couplings at each end of the cutterbar. The V1200 also comes as standard with
twin foldable Laser Pilot units and folding crop dividers. To ensure
easy and quick movement between fields, the V1200 is transported on a new
design of trailer that features equal width axles that allow it to be towed at
speeds of up to 40km/hr. The trailer is also fitted with a secure storage box
that is sufficiently large to accommodate both the oilseed rape filler plates
and side knives. |
