2021 Grimme GL Series 420 Exacta

The GL 420 Exacta is a short, combined and carried potato planter without wheels. The unique design of the machine of our potato planter Type "GL 420 Exacta" results in the smallest distance between tuber discharge and following ridge form plates, which is available on the market for potato planters with conventional arrangement of the planting elements. The small distance ensures that even on slopes the tubers do always lie perfectly in the middle of the ridge. Due to the mechanical coupling between the furrow opener and the ridge forming plate an "exact" planting depth is ensured. Up to four loosening tines can be used in front of the soil tillage implement for a deep loosening of the soil. For perfect soil preparation the option of either a rotary harrow or a full width tiller is available. The compact design of the machine without running wheels, avoids soil compaction behind the cultivator. The distinctive construction is advantageous in small, odd shaped fields and on slopes.

Soil cultivation, planting and ridge shaping in a single pass.

The potato planter with shortest distance between tuber discharge and following ridge form plates, which is available on the market - with well proven, conventional arrangement of the planting elements.

Compact design for high manoeuvrability.

Even filling of the planting elements via feeding belts.

Carrying roller to even the ground between the tractor wheels.

Simple connection between the tank system in the tractors front and the potato planter at the tractors rear side, using interfaces which are provided for this purpose.

Features may include:

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

• Different setting options of the machine together with good calibrated seed enable a high planting speed.

• Very short combi potato planter in conjunction with GRIMME Rotary Tiller GR 300 or rotary harrow, type LEMKEN Zirkon 12, for soil cultivation

• Optimum singling of the tubers via automatic filling of the planting element with a sensor operated feed conveyor

• 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.

• Option to applicate micro granular directly into the furrow for an optimum growing start or for seed protection

• Planting element arrangement in the proven design.

• 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.

• The compact design of the machine without running wheels, avoids soil compaction behind the cultivator

• The furrow openers are directly connected with the shaping board and achieve an even planting depth ensuring good growth

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