Openings provided in upper arm of balance beam, whose point of support is positioned on tillage tool frame, are adapted for altering point of attachment of hydraulic cylinder, and its lower arm is connected to supporting-transporting wheels. Hitch tongue is located forward of disk batteries at altitude N=R+H, where R is radius of disks, m; H is operating depth of disks, m. Roller is pivotally connected to frame at altitude: K=L+M, where L is distance from frame to point of attachment of replaceable hoe, m; M is operating depth of roller, m. Hoes are equipped with three-faced wedge having upper cutting edge made in the form of hyperbole.
