Blade: European and American.
There are two types of shares: European and American.
It stands out in every ploughshare: edge, beak and back. The ploughshare is set at a certain angle in relation to the direction of the plow movement. Such an arrangement of the ploughshare facilitates trimming the furrow and possible plant roots.
The bow is the most heavily loaded part of the blade. Due to the quick wear and the necessity of regeneration, the share has a thickening on the underside. This thickening is a reserve of material for the so-called. pulling the blade when regenerating.
American shares have chisel-shaped points bent downwards 5-7 mm. This makes it easier for the plow to sink into the soil and to maintain a constant plowing depth with varying soil resistances.
The shares are made of carbon-manganese steel. They are replaceable and standard parts. To reduce share blade wear, it should always be hardened (hardness 500-700 HB) on a width of approx. 40 Mm. The share blade becomes blunt during operation. Therefore, depending on the type of soil, on which the plowing takes place, Prepare 2-3 spare blades for each working day. Replaced share in time has a positive effect on the quality of the entire plowing and on the resistance of the plow. The dull plowshares are regenerated in the forge by a hardening and tempering treatment, in accordance with the repair manual.
