The GH 4 is a 4-row ridging hiller for small to medium areas and is suitable for crops cultivated in ridges at a row width of 75 to 91.4 cm (30 to 36 inch). Thanks to its light and compact design, the GH 4 requires very little lifting power and is perfect to use with small to medium-sized tractors from 70 hp upwards. GRIMME GH ridging hillers enable the build up of large volume ridges for the cultivation of potatoes and vegetable on light soils. Compared to rotary hillers, the ridging hillers use a passive-shaping soil cultivation method. This helps to reduce tractor power requirements and enables higher coverage across the field. Depending on the soil type, a range of height-adjustable loosening tines can be used to loosen the soil. For optimum care of the ridges, the machine can be adapted to individual soil conditions with a wide range of options. Single row shaper allow easy running between the rows, even in bigger plants until canopy establishment. Crops, which are grown in ridges, such as carrots or potatoes, tolerate only little competition from weeds until complete canopy establishment. For this reason, effective and accurate weed control is necessary to achieve a good yield. For growers of potatoes and vegetables, who want to destroy weeds without chemicals and build ridges simultaneously, a GH Eco Ridging hiller with integrated chopping technology is the perfect choice.
