Hand-held flat hoe-mellower / 2261564 Hand-held flat hoe-mellower has A-shaped blade equipped with side edges bent downward and fixed on body through intermediate tine formed as plate, which is mounted with its rib axially of flat-hoe-mellower. Body front part bent upward is furnished with apertures for attachment of shank by means of bolt connection or for attachment of threaded branch pipe used, in turn, for connection to shank equipped with threaded tip. Flat-hoe-mellower body is further provided with, for example, apertures for attachment of detachable load serving for reducing the action of force upon shank to substantially simplify in some situations handling of flat hoe-mellower. In operating position A-shaped blade with double-sided sharp edges is fixed at an angle of 15-30° to soil surface in the direction of advancement of flat hoe-mellower and is completely deepened into soil. Stability of deepening value and angle of attack of blade are enabled by means of restricting slides arranged at both sides of blade and fixed on body by means of number of adjusting plates. Restricting slides simultaneously serve for protecting root system of cultured plants from damage because soil mellowing occurs only in space therebetween. Such construction allows flat hoe-mellower to be drawn-through along row of plants. |
