Crankshaft spader – Gramegna
Main soil preparation that leaves land totally leveled practically automatically. Avoids and eliminates compacted soil layers in the rootzone. Ideal to increase water retention capacity and mixing in crop residue in the top soil/root zone (increases air in the soil). Improves root systems and allows long rooting crops like carrots to grow undisturbed. Works well in wet conditions and on more heavy land/clay soils.
Spades are going in and out of the soil ranging from 25-40 cm. Working speed 1.5 – 3 km/hr.
- Range of 1.5 – 3 meter models
- Can be operated from 50-150 HP
