Tillage For Zero-Till Farming
The RTS has been produced for three years and used in Ontario, Manitoba, the Midwest U.S., and even Australia. O'Grady says it's great for zero-tillers but has also been an improvement over cultivating in conventional tillage. No-till or reduced tillage operations have improved their seed-to-soil contact by using RTS for tilling the top two or three inches of the seedbed and at the same time, it successfully manages an unlimited amount of crop residue.
"We designed its individually-mounted spring coulters with a 1 1/8-in.wound coil to provide their own obstacle protection for stones," says O'Grady. "They don't pull up stones like a lot of other systems, and the coulter has no linkage or moving parts in the mounting assembly, so there's nothing to wear out. It's proving to be the longest lasting individual coulter ever developed."
The implement carries 5 to 6 ranks of these wavy residue coulters at 7-in. spacings, and has standard harrows at the back, which provide superb residue spreading and field leveling ability. To further crush and break down the residue, the RTS offers an optional roller behind the harrows.
Standard coulters have a 17 1/2-in. dia. with a 1 3/4-in. wave but options include a 17 1/2-in. coulter with a 3/4-in. wave, and a 20-in. coulter with a 2 1/4-in. wave.
The various RTS models range in width from 12 to 50 ft. with smaller ones being single-fold wing up design. The 41 and 50-ft. units are bifold models.
According to O'Grady, a key benefit to the system is that, "the faster you go, the better it works." Recommended field operating speeds are 8 to 12 mph. At those speeds, the implement requires 8 to 10 hp per foot.
Another big advantage of the RTS unit is that it allows farmers to work in wetter soil conditions than normal due to the fact that the coulters don't "ball up" with mud the way cultivator shanks do. They throw up soil so it will air out and dry.
"In a wet season, it allows you to plant earlier and in a cool season, it warms the soil," O'Grady says.
The unit sells for about $1,900 per foot and the company welcomes dealer inquiries.
