For those who want to continue to use — or return to using — tillage in their operation, Case IH has just introduced a new tandem disc model, the True-Tandem 375, which gives growers another tillage tool to consider when shopping for an implement.
Despite the fact there is certainly a lot to choose from in the tillage implement market these days, marketers at Case IH say the True-Tandem 375 is worth a close look, because it offers some updated features they think farmers will like. And it gives farmers the option to configure the implement to exactly meet their needs.
Among the new design features is the disc arrangement. To help ensure a complete and even cut, discs on the back gang track between the those on the front row. That also allows the True-Tandem to do a thorough job of burying field residue.
“Saturated soils and heavy, stubborn crop residue this year have reminded producers about the importance of crop residue management and soil tilth,” said Chris Lursen, Case IH Tillage marketing manager in the company’s press release. “Our new True-Tandem 375 disk harrow helps improve soil tilth on every front, from crop residue management to reduced surface compaction and thorough soil mixing.”
The disc uses 24-inch, crimp centre discs made of “Earth Metal,” a name the company uses to describe a proprietary process used to produce the steel alloy they’re made from. The company claims that makes the blades stronger and more durable. And they can be resharpened if necessary.
Buyers can select the shape of blades they want. They can opt for shallow concavity blades on the front gang and standard concavity on the rear, which increases the maximum possible ground speed and provides better soil penetration. Alternately, they can choose standard concavity blades on both the front and rear to maximize soil and residue mixing for improved soil tilth.
There are choices for the trailing end as well. The True-Tandem 375 is available with a new optional, hydraulically adjustable “TigerPaw Crumbler” rolling reel or spring pressure applied coil-tine harrow to help produce more-uniform clod sizing and residue distribution.
Disc gang angles are set at 18°. And they are connected to a frame made of heavy-walled steel tubing. The “Perfect Hitch” feature and extended frame size are designed to add stability and balance in the field in order to keep penetration even across the full width of the disc. And all that rides on tires resistant to stubble punctures.
“It provides better residue cutting, sizing and distribution into the soil,” Lursen added. “Yet, it accomplishes that with a smoother finish out the back for a high-quality seed bed.”
True-Tandem 375 models are available in working widths from 22 to 37 feet.
