FIELD: agricultural engineering. ^ SUBSTANCE: combined tillage tool has frame, wheels, disks on bearings, adjustment mechanism, hoes, and bars. Disks made wheel-shaped are mounted forward of hoes and arranged in two rows. Hub of each disk is furnished with two edges: front and rear. Front edge is made sharpened. Rear edge is spaced from front edge by value equal to width of hub working surface and is extending over smaller radius than front edge. Wheel-shaped disks are positioned at an angle beta to advancement line and at an angle alpha to horizontal plane of cutting soil layer by hoe edges. Wheels formed from round-section bars are disposed rearward of hoes, at an angle beta1 to advancement line and at an angle alpha1 to plane of cutting soil layer by hoe edges. ^ EFFECT: improved quality of soil tillage. ^ 8 dwg |
