The new working widths will include an all-new tyre packer roller as part of the established packer coulter system. This tyre packer incorporates four transport wheels that are used for both turning the machine on the headland and providing safe 40kph road transport due to an integrated braking system. The overall length of the drill is thus reduced by just under a metre making the system more manoeuvrable.
For these smaller working widths Amazone stay with the concept of the slim-line seed tank. Mounted close to the tractor hopper design means a clear, unobstructed view of the front cultivator disc gangs and through keeping weight on the tractor rear axle the ability for the towing tractor to maintain traction is guaranteed. This additionally means a clearer access for filling and prevents the varying seed hopper contents influencing the planting depths.
Each sowing coulter is fixed to a segment on the new tyre packer roller where each pair of segments floats individually within an interconnected hydraulic pressure equalisation system ensuring both perfect ground contour following and the targeted consolidation ahead of each sowing coulter. The additional benefit being that the sowing depth of the packer coulters is not influenced by either soil type of forward speed and the stagger on the segment pairs gives good trash flow in such a mulch drilling scenario. The concept of ‘roll first – then sow’ provides the sown grain with the perfect start by an even planning depth and excellent seed / soil contact whilst the system ensures post-drilling drainage and the prevention of capping. Each coulter is fitted with a 100kg overload safety device in case of contact with a foreign obstacle.
Cultivation on the Cirrus is provided by two rows of concave discs. These disc gangs are hydraulically adjustable for depth and are mounted on rubber suspension blocks for good contour following and stone protection release giving an ideal crumbling and levelling effect ahead of the packer coulters.
All drill hydraulic and sowing functions are controlled via the new ISO-bus ready Amatron+ in-cab terminal where the simple, easy to operate box controls and monitors calibration routine, seed rate adjustment, tramline rhythm, front cultivation disc depth, rear harrow pressure, bout markers, etc. Amatron+ comes as standard with a serial interface port for use in conjunction with a GPS terminal for site-specific variable seed rate area-specific sowing operation.
