Kuhn’s latest trailed spreader, the Axent 100.1 unveiled at a recent Cowra, NSW demonstration day, offers independent regulation of each disc to ensure accuracy on both sides.
The position of the metering outlet is corrected every second during spreading according to torque measurement on each disc.
The system is designed to ensure accurate application rates from each metering outlet, reduce clogging, and detect and correct flow variations instantly.
Kuhn says other machines on the market have either a static or sequential weighing system meaning comparisons are made between a full and empty machine before adjusting metering outlets for the following load, meaning regulation is never carried out continuously during spreading.
With a 9400 litre hopper and 10,400 kilogram maximum load capacity, Kuhn says the Axent 100.1 suits bigger croppers.
The machine is a modular design and it takes less than ten minutes to interchange the two spreading modules available.
The first module, the Axis PowerPack is for precise spreading of granular fertiliser from 18 to 50 metres.
The Axis PowerPack offers the advantages of a mounted spreader to ensure high-precision spreading: EMC regulation, CDA distribution, 500 kilogram a minute flow, ultra-slow rotating agitator, and spreading width from 18 to 50m.
The fertiliser supply is totally automated, with no driver intervention required.
As soon as the level of fertiliser gets low, the feeding belt automatically starts up again.
The lime PowerPack has 700 millimeter diameter heavy discs to spread lime, moist bulk organic fertiliser, including pellets, at high application rates over a maximum width of 15m.
Variations in feeder belt speed, according to groundspeed, make it possible to reach application rates of several tons per hectare.
A beater improves flow to the spreading discs.
Product-specific spreading modules make the Axent 100.1 uncompromising in terms of precision.
The Axent can be optioned with a steering axle to limit crop flattening and improve performance on slopes.
The Trail Control system uses a gyroscope positioned on the tractor to adjust the Axent’s wheel angle.
Turning angle is from 10 to 17 degrees depending on track width and tyre size.
The linkage drawbar has hydro-pneumatic suspension.
The hydraulic unit drives the spreading discs, feeder belt and outlets and is powered by the power take-off at 750 RPM to reduce tractor fuel consumption.
With no oil flow requirement, it is totally compatible with medium sized tractors.
All spreaders in the Axis series 2 range and Axent 100.1 equipped with new electric cylinders to control drop points, come with the VARISPREAD Dynamic system to manage field points.
This system continuously adapts the position of the spread with Kuhn saying it is no longer a matter of section management but of continuous variation.
Field point and overlap management is even more precise.
