A double take on tandem discs

After its $14.5 million purchase of Alberta-based Ezee-On Manufacturing, Buhler Industries has added the former Ezee-On tillage equipment it acquired with the company to its Versatile and Farm King-branded lines.

“The acquisition of Ezee-On is another step in the process of becoming a full-line equipment manufacturer,” said Dmitry Lyubimov, President of Buhler Industries, when the purchase was announced back in February.

The former Ezee-On tandem and off-set discs will now wear Versatile and Farm King names, but they will still be built at the same plant in Vegreville, Alberta. The discs, along with the former Ezee-On’s cultivator designs, now give these brands a respectable tillage component.

“We have been very open about our intention to have Versatile offer a product line that caters to the large-acre farmers, and these implements are a major part of that strategy,” adds Lyubimov.

The company says the bearings used on their line of discs are the heaviest in the industry. As a result, it offers a three or seven-year warranty on them, depending on the component size. To further improve durability, the disc gangs are torqued to 3,200 foot-pounds. Steel fabricated full spools and interlocking half spools ensure they stay tight.

The tandem discs are designed for the farmer who wants a tool capable of handling trash and incorporating residue. Their full-floating hitch helps create a smooth field finish and minimizes disc damage from striking rocks or other field hazards. To add an additional level of protection against stone damage, an optional C-shaped, flex hanger can be ordered, which reduces shock loads on the gangs. Tandem models are available in 500, 600 or 700 pounds-per-foot configurations. Blade diameters run from 22 to 30 inches.

The tandem discs models can be purchased in working widths from 12 to 42.5 feet.

The offset discs are available in weight classes of 550, 650 or an industrial-scale 1,050 pounds per working foot. Blade sizes range from 24 to 30 inches across the models, and they are available in notched or smooth styles. Gang angles are adjustable. The offset designs are available in widths ranging from six to 20 feet.


AGCO, too, has new models in the tandem and offset disc category. At its official product launch in Kansas City, Missouri in August, the company introduced its all-new 1800 Series tandem disc harrows and 1700 Series offset discs.

The 1800 Series is available in two different models, the 1810 and 1830; both come in a variety of configurations. Working widths for the 1810 models range from 14 feet, four inches to 17 feet. The wider, 1830 designs extend up to 39 feet. Weight per blade ranges from 333 to 523 pounds in the narrower 1810s, and 402 to 635 in the 1830s.

“Professional producers looking for a durable machine that can break through hard-packed soils and thick crop residue need not look any further than the Sunflower 1800 Series Tandem Disc Harrows,” says Larry Kuster, senior product specialist for Sunflower tillage equipment. “These machines are designed to efficiently incorporate heavy residue into the soil.”

AGCO is now using 5/16-inch-thick boron blades on both series. The new boron alloy is more durable than what the company had been using to manufacture disc blades for previous models, giving them a longer life. “Since we started using boron blades, breakage has been significantly reduced,” adds Kuster. Disc blades are available in 28- or 30-inch diameters in notched or plain styles.

The 1800 models also offer protection from rock damage with spring-cushion mounted gangs.

The 1700 Series Sunflower offset discs are available in two models as well, the 1710 rigid frame and 1730 flexible frames. The 1710 is for farmers looking for primary tillage capability in a smaller-sized implement. They are available in working widths from 11 to 17 feet, 11 inches. Weight-per-blade ratings run from 299 to 441 pounds. The 1730 models range from 21 feet, five inches to 24 feet. The gang angle is also adjustable.

“With two styles to choose from within the 1700 Series, producers are certain to have no trouble finding a machine tailored to any size farming operation and varying soil conditions,” says Kuster. †
