2021 Grimme GL Series 420

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.

TerraProtect creates small transverse ridges, so-called dykes, between the potato ridges. The dykes reduce the risk of erosion and at the same time promote water absorption.

For an improved water absorption on light soils, cage rollers can be used in combination with spring-loaded ridging bodies.

Convenient especially for short headlands and smaller acreage. A compact tractor implement combination of potato planter GL 420 and rotary tiller GR 300 is available for these requirements.

The potato planter GL 420 can be equipped with the LEMKEN Zirkon 12 rotary cultivator for soil cultivation and planting in a single operation step.

GRIMME tank system TS 820, authorized for liquid chemicals to be applied onto the seed potatoes and/or into the furrow.

For all who want to benefit from the winning margin offered by pregermination, GRIMME offers a long moving floor bunker. The long floor offers you more time to gently pour following tubers onto the supply belts.

Features may include:

• The powerful planting element enables a simple adaption to the tuber size and ensures therefore an exact planting distance.

• Less seed potatoes required with the automatic single row deactivation of the planting elements with Section Control.

• Clever Planting: Increased share of marketable crop due to a improved, homogeneous growth and tuber size in the rows next to the spraying tracks. This is achieved by an infinitely adjustable, reduced tuber spacing and the resulting change in competition for light and nutrients along the spraying tracks.

• Various hopper options: Tipping hopper flat (2000 kg), fixed hopper (1200 kg) or tipping hopper low (1700 kg)

• 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.

• 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 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.

• Variable Rate Control (VRC): By use of electronic application maps the machine is able to realise precise, variable tuber spacing for each single row.

• Operation via ISOBUS from the tractor terminal
