Abstract: An agricultural primary tillage implement is disclosed with a row cleaner assembly attached in front of the shank. That row cleaner is adjustable fore-and-aft for optimum clearance between the shank and a leading soil preparation apparatus to maximize clearance for residue movement. The row cleaner is also adjustable for depth. The row cleaner assembly reduces the amount of residue in line with the shank path (row) and creates smaller clod sizes of soil in line with the shank swath, resulting in a better seedbed and faster warm up in the spring, enabling the planter to run in cleaner soil, preventing planter plugging and uneven seed planting depth as well as resulting in better seed-to soil-contact.
Abstract: A tillage implement for preparing seed beds for planting seeds for row crops. The implement includes deep tillage units for loosening soil behind the wheels of a tractor, additional deep tillage units for loosening soil in the areas where seed beds are located, seed bed shaping units, and ribbed wheels for providing guide tracks in the soil for use in aligning a planter with the seed beds.
Abstract: A cultivator implement has two rows of freely rotatable, tined soil-working members connected to leading and rear transverse frame beams by respective brackets or plates. Each rotatable member is mounted for rotation on a corresponding stub shaft that defines its axis of rotation, which is inclined to the vertical. Pairs of downwardly extending tines that are secured in respective holders around the axis of rotation, contact the ground and rotate each member. A first row of rotatable members have axes inclined to one side of the vertical and a second row of rotatable members have axes inclined to the opposite side of the vertical. A fixed cultivator tine is deflectably secured to the beams via an integral spring coil assembly. The cultivator tines are positioned non centrally between adjacent rotary members and each tine is curved so that its lower tip extends forwardly.
