New Heavy Residues Row-Crop Cultivator
First on the market with a heavy duty row crop cultivator designed to work in heavy straw, corn stalks and other residues is the Hiniker Co., Mankato, Minn.
Called the Econ-O-Till, it provides precision cultivation of newly-emerged row crops in the heaviest residues without plugging or bunching, according to Jim Johnson, product manager. The new-style cultivator can also be used to knife anhydrous ammonia into heavy residues. What's more, it converts from a precision cultivator to a hilling machine in only a couple minutes by a special soil-ridging attachment on each shank. The soil pushing action of each ridger allows hilling of short corn plants without damaging the crop, yet covers weeds in the row with enough dirt to kill them. If you don't want to ridge, the ridging attachment on each shank is raised up on the shank where it rides up and out of the way when not in use.
Adjustable down pressure springs on each shank plus filling the 7 by 7 inch toolbar with concrete transfers up to 840 Ibs. of downward pressure on individual trash-cutting coulters. "This cutting disk, thanks to the extreme amount of pressure our exclusive design provides, is the key feature that allows the Econ-O-Till to operate in the heaviest residues, and at high speeds. We planted soybeans directly into 150-200 bu. corn residue with no pre-plant tillage and had no trouble with trash either in planting, or in cultivating the beans a few days after emergence. With the concrete filled toolbar, weight runs right at 650 lbs. (30 in. spacing) to 735 lbs. (40 in.) per crop row."
In addition to cutting and dividing residue ahead of each sweep, the coulters also serve as stabilizers to prevent side sway. A rubber tire gauge wheel (4 in. wide, 16 in. dia.) on each cultivator gang provides support and flotation. A pair of 14 in. disk hillers cut away from the crop row in the heaviest residue without plugging, according to Johnson.
The Econ-O-Till is available in 4, 6 and 8 row non-folding models, and 8 row wide (40 in.) and 12 row narrow (30 in.) folding models.
