Bushing is extending to mid portion of bayonet and is equipped with sharpened front end having edges contacting with and rigidly connected to flat bayonet.

Method and apparatus for controlling of soil erosion on slopes / 2246807
Method involves undercutting soil layer after harvesting of preceding crop; directing stubble remains under soil layer and covering with undercut soil layer. After being covered with undercut soil layer, stubble remains form along edge of said layer swath of soil layer of 4-6 cm width. Predetermined shape and parameters of swaths allow evaporation of moisture and silting to be inhibited and, accordingly, moisture retention to be increased. Apparatus has frame with carrier wheel and flat rack provided with front cutting edge and inclined with its lower end forward and to the side. Flat hoe is fixed on lower end of rack. Wing made curvilinear along direction of advancement of apparatus is positioned at rear edge of rack so that its convex part is extending upward and to the side. Load feeding belt conveyor is connected with frame through two pivot links. Flexible rods for picking up stubble remains from field are fixed on conveyor belt. Belt conveyor is positioned on tines of supporting rollers and is oriented with its feeding end under upper curvilinear edge of wing. One of pivot joints and tines of supporting rollers are equipped with individual length regulators.

Apparatus for forming of intermittent micro raised portions / 2246808
Apparatus has frame and blade-type swivel connected with frame by means of free-motion mechanism. Blades of swivel are made concave and movably fixed thereon. Locking mechanisms for each individual blade are mounted on blade-type swivel. Locking mechanism switch is positioned on frame. Such arrangement and interconnection between said parts of apparatus allow micro raised portions to be provided within wide range of soil conditions.

Spade and working tool for spade / 2253205
Spade has working tool comprising ladle-shaped casing made from polymeric reinforced material and provided with front edge portion formed as blade, and devices for connecting to handle. Strengthening head is attached to blade of working tool casing. Strengthening head has V-shaped section and is manufactured from impact-resistant material. One side of head is arranged on face side of casing of working tool and other side with at least one attachment member is arranged on rear side of casing.
