Automatic implement operation and satellite-guided section control has reached the hay field with the introduction of GeoSwath for the GeoRake versions of the Kverneland 97150C and Vicon Andex 1505.
The 4-rotor grass rakes, which have stepless hydraulic working width adjustment from 9.8m to 15m (32ft to 49ft) and also hydraulic working height regulation, normally need a skilled operator to achieve maximum performance and neat swaths across the field.
But the GeoSwath and other automated features enable the operator to concentrate on steering and speed alone.
The front 2 rotors can be angled in, to fine tune the working width on-the-move, all 4 can be lifted out of work individually for larger changes in width, and the rotors can be lifted in front and rear pairs when approaching and leaving the headland.
All these functions can be automated on the GeoRake machines, thanks to the GeoSwath software package for the Kverneland IsoMatch Tellus Pro isobus terminal, which also provides sprayer, spreader and seed drill section control.
Once the boundary of a field has been recorded or recovered from memory, raking can switch to automatic, significantly reducing the operator’s workload during headland turns by lifting and lower the rotors as necessary, to avoid dislodging headland swaths.
Straight, well-formed swaths are produced by angling inwards either of the front rotor arms where the unraked area becomes narrower, or lifting out of work 1 or both rotors on 1 side of the machine, if necessary.
Kverneland believes that in addition to reducing the operator’s control workload, the GeoRake machines work more efficiently and achieve higher work rates.
