Grimme GL 420 and GL 430 four-row cup potato planters and its GB 430 belt planter have received various new features.
For section control on the cup planters, GL 420 and GL 430, the manufacture has developed an alternative to the traditional hydraulic individual row drive.
Drive to all rows is now provided by one hydraulic motor, turning a full width shaft. Electro-magnetic clutches can now be used to engage/disengage each row from the operator terminal. As an option, each row can be automatically switched on and off using GPS.
The four-row potato belt planter can be fitted with the option of the firm’s TerraProtect Pro, a dyking system, designed to reduce the chance of surface run off during periods of heavy rain and creates small pockets of water for an even supply to the crop.
The system consists of a loosening tine preceding the spade-like dyking device. The tine loosens the ground and increases the capacity of water absorption of the soil.
Adapted to the contour of the ridges, the dyking system generates traverse-dams for water storage, by dropping into the soil between the ridges and drawing out a hollow. Automatic control of the system adapts the frequency of dyking to variable driving speeds. Individual rows can be switched off where a sprayer tramline needs to be placed.
The option is priced at £7,000.
