The plough (Fig. 2) is long with a big and "soft" bending as to the aim indicated on (Fig. 3). The sledge (3) (Fig. 2), which can be adjusted in its height, holds the plough in the desired depth and thereby the turf will be cut into the preferable thickness used when planting potatoes. The small share (5) (Fig. 2) cuts the turf only half way through, so it is stuck and is directed as wished, both when planting and digging up potatoes (10) (Fig. 3), also indicated on (Fig. 6). The reverse plough (6) (Fig. 5) is as to the aim indicated on (Fig. 6) where the turf is turned over when digging up the potatoes. The clevis is standard for tractor hitches. The same clevis is used for both ploughs. The clevis can be assembled or unassembled when needed with the bolts indicated on (Fig. 1 and 4). The ploughs can especially be used in the Faroe Islands, where the soil is soft and deep. The machines can very easily sink. They do best when operating on grass field, e.g. by growing potatoes in turf. |
