FIELD: agricultural engineering, in particular, hand-held tillage equipment.

SUBSTANCE: tillage tool has moldboard part 1 and handle part 2. Supporting device made in the form of crankshaft and attached to handle part 2 is composed of arm 3 with cantilevered handle fixed at arm end. Arm 3 is connected with fork 4, which is connected to tine 5 terminated in supporting shoe 6. Fork 4 is connected through pin 7 to pendulum suspension 8 made in the form of yoke. Supporting plate 9 arranged inside yoke is fixed to pendulum suspension 8 by clip 10 and to arm 2. Pin 7 has holes at its ends, said holes being adapted for insertion of spindles preventing pin 7 from spontaneous exit from fork opening. Pendulum suspension 8 rotates on pin 7 for allowing apparatus to rotate through 120 deg in vertical plane. Supporting plate 9 is attached to arm 2 so that supporting shoe 6 is arranged slightly lower than upper edge of moldboard part 1 of apparatus.

EFFECT: enhanced reliability in operation, simplified construction, reduced power consumption and labor intensity.
