how to used farm moldboard plows
Moldboard plows
There are two types of plows: one-way plows, two-way plows and one-way plows are the most common for their simplicity. The two-way plow has two sets of contrasting wheels which can be used as a choice. In this plows, all grooves can be rotated on the same side of the field using the right hands in the direction of the left and the left in the case of return. These plows consist of the body, the stalk, the frame and the wheels. The heart or fragmentation of the education and the basic function of the body of the plow is the cut groove slice and the fragmentation and heart of the groove harvested and all the plows, which currently have a normal weapon to be disposed of in the case of consumption. These weapons are available in various forms. It is made with a specific length and shape and is fixed by rivet screws. The body of the plow must have head clearance and side grooves for easy preservation of the depth and width of the desired pieces.

The hammers are usually made of low carbon steel in the center and the outer layer of the high carbon steel castor. After thermal treatment, the outer layers become solid and have soft surfaces with high corrosion resistance in most of the soil. As a result of its low carbon content, the middle layer is affected by the thermal process. It is therefore soft and gives an ability to absorb shocks. Low carbonization can be made in its carbon content to obtain solid surfaces.
Many different types of hammers are developed. Common species include general purpose objects, root floor beds, plant residues, muddy wetlands, deep plowing and black land. The root-filled land has a low, long, gradual curvature and a spiral shape that allows the kidney of the groove to be harvested with the least amount of cracking, thus leading to full vegetation coverage. The short and wide body with a sudden bending at the end leads to more fragmentation compared to the burner Other. The body of the general purpose is the middle between these two types of the extremes of eternity. It is fit for a wide range of conditions and conditions. The black earth has a relatively small surface and a shape that helps to slide into those heavy lands. The shape of the plow can be distinguished by measuring the horizontal coordinates of the equator at equal vertical distances and drawing the results at the horizontal level of the body
There are several types of disk knives and used disk knives to help cut the groove wall, as well as to cut plants on the surface of the soil, which may accumulate in front of the weapon, or on the plow frame and thus impede its performance. Knives with flat surfaces are used in fields free of strong plant residues.
The disk-shaped disk with the curved edge and the other with the corrugated edge work well in the soil where the plant remains are abundant. The disk's Nirvana will be found directly above the side of the weapon or 1-2 centimeters in length. The large diameter disk drive works easily in the case of intensive crop residues, which are better than small diameter Nirvana, but penetrate the solid earth less.

The forces needed to tighten the plow-Draft of plows
The strength of tensile strength is influenced by many factors such as soil type and wetness, speed of tillage, plow shape, unit and shape of arms, depth of tillage, cut groove width, types of accessories, method of control of plow and its components, and main factors contributing to changes in tensile strength The type and condition of the soil The specific tensile values range from 1.4 to 2.0 N / cm2 in sandy soil and up to 14 N / cm2 in heavy clay land. While 4 to 8 Newton / square centimeter of clay clay and soil moisture content are important factors affecting tensile strength and performance, as dry soil requires high capacity. It was found that the increase in humidity from 9.1 to 11.7% reduction of the qualitative tensile in soft sandy soil from 15 to 35%. The degree of clamping, pre-soil treatments and the type of crop residues affect the qualitative tension.
Many experiments have shown that the specific strain of plowing usually decreases as the depth increases to an optimal ratio from the depth of tillage to plowing and then the qualitative tensile increases as the depth increases. The shortfall that occurs at the beginning is logical because the total force needed to cut the bottom of the groove does not depend on depth. The increase in the tensile strength after optimum depth is due to the increase in soil accumulation due to the deep depth on the surface of the Hammers.
