Planting technology - Cup planter | GL 420

4-row, up to 2 t hopper, mounted, for a versatile application range

The GL 420 is a mounted, 4-row potato planter with a unique variety of options for almost every grower. The GRIMME professional planting element is the right choice for a very precise and even planting distance. Different setting options of the machine together with good calibrated seed enable a high planting speed. The machine design with large covering discs in front of running wheels enables easy pulling of the machine, pre-shapes the ridge and avoids soil compaction of loose soil by the running wheels. Several work steps can be combined with the cup planter GL 420. Integrating features such as active soil cultivation, application of granulates, furrow treatment agents and liquid tuber dressing, placement of the tuber, ridge building and erosion control, everything can be realised. The machine can be optionally equipped with solutions for the implementation of Clever Planting, Section Control and site-specific farming using application maps.

Benefits

• The powerful planting element enables a simple adaption to the tuber size and ensures therefore an exact planting distance.
• The combination of specially developed furrow opener, planting cups, the longest singling way, an adjustable drop rod and a low drop height enable an even planting distance in the required planting depth.
• Less seed potatoes are required with the automatic single row deactivation of the planting elements with Section Control.
• Variable Rate Control (VRC): By use of electronic application maps the machine is able to realise precise, variable tuber spacing for each single row.
• Clever Planting: Increased share of marketable crop due to an improved, even growth and tuber size in the rows next to the spray tracks. This is achieved by an infinitely adjustable, reduced tuber spacing and reduces the competition for light and nutrients along the spray tracks.
• Operation via ISOBUS from the tractor terminal
• Four wheels, following the covering discs, ensure a good weight distribution, stability and good traction.
• A combination with a cultivator is possible for an optimum soil preparation.
• Various hopper options: Tipping hopper flat (2000 kg), fixed hopper (1200 kg) or tipping hopper low (1700 kg)
• Uniform growing through constant soil covering of the tubers via hydraulic depth control of the furrow opener and automatic shaping board steering. The planting depth can easily be controlled and adjusted from the cab.
• A shaping board can be used for building ridges with specific characteristics from loose to firm soil with a smooth surface. There are several versions for ridge shaping bodies available for a perfect adaptation to different soil conditions, ridge shapes and ridge volumes.
• For an improved water absorption on light soils, cage rollers can be used in combination with fix or spring-loaded ridging bodies. The cage rollers provide a light, airy ridge with an open-pored surface.
• Protection against erosion: The "partnership" of a loosening tine and the dyker, both working between the ridges, TerraProtect ensures a more efficient water absorption in the ridges and also provides maximum protection against soil erosion.
• The GRIMME nozzle system ensures complete dressing of the tuber, and the GRIMME tank system enables a safe handling as well as a proper crop protection
• Option to applicate micro granular directly into the furrow for an optimum growing start or for seed protection
