#CMT# #/CMT# Sowing machine comprises a drawbar (1), and a main frame (2) on which a frame (17) for rollers (36) is arranged that is rotated about an axle point (C) by an adjusting element (18). The main frame has at least two fixing shafts (4, 5) on which blade arms (6, 7) are fixed so that they rotate about hinge points (A, B). A tensioning device (30) is fixed to the upper ends of the blade arms and at one end to the frame for the rollers below the axle point at a point (J). #CMT#USE : #/CMT# For sowing seed. #CMT#ADVANTAGE : #/CMT# The running depth of the seed blades in non-cultivated and cultivated soil is controlled. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic side view of the sowing machine. 1 : drawbar 2 : main frame 4, 5 : fixing shaft 6, 7 : blade arm 17 : frame 18 : adjusting element 30 : tensioning device 36 : roller A, B : hinge point C : axle point J : fixing point.
