Abstract
The farm implement of this invention is movable across ground along a direction of travel for tillage. The farm implement includes at least a frame and a multi-disc unit. The multi-disc unit includes pluralities of first and second discs, each having a ground-engaging outer periphery defining a plane angled acutely relative to the direction of travel. The first discs are angled to an opposite side of the direction of travel than the second discs. Positioned between the plurality of first discs and the plurality of second discs is a flow controller assembly, preferably a coulter assembly, which is rotatable in a forward direction for directing the tilled ground between the first and second discs.
Claims39
A farm implement movable across ground along a direction of travel for tillage of the ground, the farm implement comprising:
- a frame;
- and
- a multi-disc unit coupled to the frame, comprising
- a plurality of rotatable first discs having respective first ground-engaging outer peripheries for engaging and tilling the ground, each of the first ground-engaging outer peripheries defining a respective first plane angled acutely relative to the direction of travel for directing the tilled ground in a first generally transverse direction relative to the direction of travel;
- a plurality of rotatable second discs arranged behind the first discs along the direction of travel having respective second ground-engaging outer peripheries for engaging and tilling the ground tilled by the plurality of rotatable first discs, each of the second ground-engaging outer periphery defining a respective second plane angled acutely to an opposite side of the direction of travel than the first planes for directing the tilled ground in a second generally transverse direction relative to the direction of travel;
- and
- a flow controller assembly situated between the plurality of first discs and the plurality of second discs and rotatable in a forward direction for knocking down ground tilled by the first discs for tillage by the second discs.

- and
- a flow controller assembly situated between the plurality of first discs and the plurality of second discs and rotatable in a forward direction for knocking down ground tilled by the first discs for tillage by the second discs;
- a coulter assembly coupled to the frame, the coulter assembly comprising a rotatable coulter shaft situated behind the plurality of second discs along the direction of travel, the coulter shaft having an axis substantially perpendicular to the direction of travel, the coulter assembly further comprising a plurality of coulter blades spaced axially relative to each other along the axis of the coulter shaft, each of the coulter blades having a ground-engaging outer periphery, the outer peripheries of the coulter blades defining respective third planes parallel to the direction of travel;
- a reel assembly coupled to the frame, the reel assembly comprising a rotatable reel shaft and a plurality of elongated blades, the reel shaft having a periphery and being situated behind the plurality of second discs along the direction of travel, the longitudinal blades being spaced circumferentially about the periphery of the reel shaft along a helical pattern and having a ground-engaging edge for chopping debris and breaking soil clods;
- and
- a plurality of rows of at least one member selected from the group consisting of chisel shanks and tines supported by the frame, the rows disposed behind the plurality of second discs along the direction of travel, each of said at least one member having an edge portion distal to the frame for engaging and penetrating the ground.
