Build your own coulter-chisel
If you're looking for an inexpensive way to convert to conservation tillage, you might want to consider converting your chisel plow to a coulter chisel, allowing you to combine disking and chiseling operations in one pass.
All it takes is add-on coulters mounted ahead of each shank, says Mitch Romer, director of marketing for Yetter Mfg. Co., of Colchester, Ill. The company offers disk-chisel coulters in 17 or 20 in. dia. The self-sharpening, ripple blade coulters slice the trash and residue so the chisel can shatter and incorporate with less horsepower.
"Plugging problems are reduced and the . result is better protection against wind and rain erosion. The coulters also reduce implement draft while making one pass possible in trashy conditions," says Romer. "They're ideal for farmers who want to eliminate trips over the field, leave more trash and save the soil without having to spend big money. For example, on an 11 shank chisel plow, you can addd coulters for under $2,000 about a third the cost of a new coulter chisel implement. Besides, many dealers won't give you much for your old chisel plow."
Romer says brackets are available to fit Yetter disk-chisel coulters to 95% of all chisel plow makes and models. "Each coulter swivels separately so there's no problem with trash being pushed along in front, or mud balling up between them. And, because the coulters precut for each skank, slightly less horsepower is required. The coulters are spring loaded to prevent bouncing and to cut through trash and tough ground conditions. Down pressure can be adjusted for ground conditions, depth of cut and blade wear.
"In normal situations, you don't need to add weight to get coulters into the ground. In heavy trash, you may want to add weight, especially on chisel plows which don't have the frame filled with concrete," says Romer.
In addition to fitting chisel plows, the coulters can be easily adapted for use with field cultivators and planters. .
