Shallow tilling and power harrows

The present invention uses a plurality of sets of shallow, nominally vertical coulters that are placed directly behind also as ahead of the deep tilling tines at adjustable, selected distances. The shallow tilling coulters could also be dispersed in several rows, some ahead of the deep tilling tines and a few always behind the deep tilling tines and should have several shapes. The coulters could also be within the sort of toothed tine rotors or rotors with a ruffled structure. These shallow tilling coulters haven't any specific spacing reference to the spacing of the deep tilling tines and are generally present during a much greater number than the amount of deep tilling tines employed. When a shallow tilling coulter is placed ahead of the deep tilling tines, it functions to size the crop residue and clears the bottom facilitating the smooth operation of the deep tilling tines. All the shallow tilling tines are run at the bottom speed of the tillage system. The depth of till for the shallow till coulters is adjusted by moving the coulter wheels up or down. This adjustment is effected by the operator of the tillage system and is nominally within the 1 to 4 inches range. The surface tilling coulters, therefore, clear much of the plant debris within the field between the deep tilled grooves. They also stir and blend the soil. Preferably, the shallow tilled portions of the sector tilled by the coulters only disturb the soil slightly providing space for the water absorption from rain or artificial irrigation. Water run-off is substantially prevented. the sector provided by the tilling practice of this invention exhibits a neat appearance characterized by the removal of perennial weeds previously extant between the deep tilled grooves. The toolbar could also be increased in breadth by adding a group of hydraulic folding wings that carry a similar arrangement of tines.

For example, a typical tillage system features the first row of deep tilling tines, the second row of curved coulters designed to displace the tilled soil laterally perpendicular to the movement direction. These curved coulters could also be lifted off above the bottom when not needed. the 3rd row of shallow tilling toothed coulters is provided the orientation of which is about from zero to 10 degrees with reference to the travel direction of the tillage system. The inclined toothed shallow tilling coulters displace soil laterally eliminating mounds and mixing plant debris with the soil during a manner almost like curved coulters and should function better in some soils or crop fields. a final fourth row of ruffled disks shallow tilling coulters is usually provided to combine the plant debris into the tilled ground, binding the soil from water erosion. A 5th row of soil surface landscaping tools like a power harrow for sale, cage roller tool or packer wheels could also be included. A shallow tilling toothed coulter could also be additionally added ahead of deep tilling tines to size tall plant debris within the field enabling tilling deep tilled grooves within the field more easily. the amount of shallow tilling coulter and its order could also be changed consistent with the requirements of the field being tilled.

Advantageously, the tillage system of this invention leaves behind a clean tilled field with little or no or no unsightly weeds and a plurality of deep tilled grooves for row planting of a crop. The deep tilled grooves don't have mounds on either side thereof thanks to the tilling action of the shallow tilling coulters. additionally, the sector surface is well leveled and free from water running channels, a key feature that forestalls water runoff.
