摘要： PURPOSE:To manufacture a blade body fit for use for a long period by sticking powder having high hardness and wear resistance to the part of a base material to be hardened and by forcing the powder into the part to form a hardened layer. CONSTITUTION:Powder 3 having high hardness and wear resistance such as WC or TiN powder is stuck to both sides or one side of the part 2 of a black 1 to be hardened to form the edge of a blade body with a binder to a proper thickness. The blank 1 having the stuck powder 3 is made red-hot by heating in a heating furnace and the powder 3 is forced into the surface layers of the part 2 by rolling to form hardened layers 4. The resulting blank 5 for blade body is finished to the final shape of a blade body by forging, pressing or other means to obtain a product.

摘要： PURPOSE:To improve the wear resistance of an edge body and to reduce the manufacturing cost by forming a powder body having a high hardness and a high wear resistance, in the corresponding surfaces of a pair of base material steel plates, and subsequently, polymerizing and joining each powder layer by the means of rolling, forge welding, etc. CONSTITUTION:On an edge body manufacturing line, a hopper 7 containing a high hardness/high wear resistance powder body 8 is provided, and also a calcination furnace 9 is provided. By the calcination furnace 9, a base material 6 is brought to red heat at a high temperature, and also the powder body 8 is calcinated and a powder layer 10 is formed on the base material 6. Also, in other line of the same kind, a powder layer 10' formed by making a powder body 8' adhere onto a base material 6' is formed, and both powder layers 10, 10' of the materials 6, 6' are pressed strongly against a clad roller 12. According to this method, the powder layers 10, 10' are anchor-coupled firmly to each other, and an edge body base material A which are polymerized and joined strongly is obtained. Accordingly, the wear resistance of the edge body A is improved and the manufacturing cost can be reduced.

摘要： Cultivating tines, each having opposite cutting edges, are pivotably supported by tine mount members on a tine shaft reversibly rotatable about a horizontal lateral axis. One of the cutting edges of the tine is retainable in a position rearward with respect to the direction of forward rotation, while the other cutting edge is retainable in a position rearward with respect to the direction of reverse rotation. When held in each of these positions, the tine is restrained by resistant force imparting means from being pivotally moved by a centrifugal force. The resistant force to be imparted by this means is smaller than the reaction to be produced when the tine is driven into the soil.

摘要： PURPOSE:To eliminate extremely forward slant placement of a working machine on the ground in connecting a tractor to the working machine, by setting specific oscillating members in a specific state and laying a means to releasably lock the oscillating members in the maximum oscillation position at the opposite side of the tractor. CONSTITUTION:A left and right pair of oscillating members 40 are supported by a shaft 41 on front part of a left and right pair of attaching plates 17 of a coupling member 14 connect side end part of a working machine of a top link 10 and both low links. The oscillating members 40 are releasably locked in locking members 55 at the maximum oscillation position at the opposite side of a tractor wherein an engaging shaft 42 inserted into the oscillating members 40 is engaged with cut dents 43 of the attaching plates 17. The maximum oscillation position of the oscillating members at the tractor side is a position wherein the base part of the oscillating members is brought into contact with a main body 15.
