agricultural engineering. SUBSTANCE: apparatus has casing with two parallel plates spaced one from another by distance commensurable with length of fruit spur. Double-sided grip in upper part of casing is equipped with slot having parallel vertical edges and oval-shaped apex. Spring-loaded triple-link crank mechanism is mounted between casing plates and has L-shaped rocker knife with cutting edge and bent portion provided with longitudinal recess, and fixed spindle at the end of bent portion of L-shaped knife. Fixed finger is inserted into recess. Crank mechanism has crank lever with return torsional spring and drive tie-rod. Spindle forms rotating pair with first arm of crank lever mounted on fixed spindle. Plank-drive tie-rod is attached through spindle to second arm defining acute angle with first arm of crank lever. Finger and fixed spindle of rotation of crank lever are arranged in succession relative to recess at opposite sides with respect to parallel projection thereof. Rigid collar is fixed perpendicular to upper part of casing and accordingly to grip for defining fruit guide throat. Unit for attachment to pole is fixed to opposite side of casing. Such construction eliminates cutting tool wedging and reduces operating loads applied to fruit spur intersection mechanism members. EFFECT: simplified construction and increased efficiency. 2 dwg
