A drill for every field
Representing a unique opportunity for growers to own multiple drills within a single machine, the izona iPass has been designed to be equally at home drilling into cultivated land as it is drilling into high residue cover crops and stubbles. The variability of set up combined with the consistency of establishment appeals to both growers looking to reduce cultivation and advance to a direct system, as well as those who are well established with minimum tillage and want a reliable and consistent machine.
Auto-reset leading tines and front discs clear crop residue from the seeding zone to produce a clean till of moist friable soil whilst band placing fertiliser to promote good root development. Accurate seed depth is maintained across the width of the drill with independent, hydraulically pressurised coulter arms each free to self-steer behind the path of the leading tine. Uniform row widths are maintained even on headland turns.
The coulter legs are suspended by a parallel linkage that ensures the coulter angle is unaffected by depth and offers control independent to the front cultivation zone.
A unique ball joint system gives the coulter arm exceptional ground following and self-steering capabilities for uniform emergence over undulating ground. Trailing in-line behind the leading tine and front disc, the coulter arm self-steers on a cambered pivot, likened to the motion of a motorbike around a corner. This action naturally wants to draw the tip of the coulter in-line with the front leg creating accurate seed placement in relation to the tilled zone around obstacles and sharp headland corners.
A commercial 18 tonne rated axle with floatation tyres accommodates an extra-large hopper for increased productivity and reduced downtime. Hydraulic brakes are supplied as standard with air brakes available as an optional upgrade.
With a combined volume of 7000 litres the 60/40 split hopper is pressurised for metering and conveying high application rates efficiently. Seed and fertiliser are delivered from the large capacity tank via four variable speed electric metering units designed for high output delivery for accurate placement at higher speeds. One to each side, two units control fertiliser and two control seed giving operators the option to shut off half of the width.
The iPass metering system can accommodate all fertiliser compounds and seed types typical of most arable operations including small OSR and grass seeds to large Maize and Winter Beans. The metering units have been mounted either side and to the underside of the tank for easy to reach calibration thus further minimising down-time.
A generous twin ladder platform has been incorporated for good access to the tank for inspection and filling and doubles up as centralised housing for the fans and electronic systems.
The iPass is available in 6 metres with 18 or 24 coulters, and 8 metres with 24 or 32 coulters.
