Weighing in at approximately 1,488 kg/m (1,000 lbs/ft) of implement, the Wishek 842NT is a tandem disc with 28 cm (11 in) disc spacing that performs in some of the toughest ground conditions, and its durable design has a reputation for lasting many years.
Seedbed preparation can be made easier in the spring by running the Wishek 842NT as a primary tillage pass in the fall.
The Wishek 842NT is a tandem disc that offers excellent mixing performance to incorporate large amounts of residue for fast decomposition.
Large concave 71 or 76 cm (28 or 30 in) discs with smooth or notched blades on the Wishek 842NT are designed for superior cutting and mixing performance to help create better tilth in hard, heavy soils.
A post-harvest tillage pass is essential for preparing a superior seedbed in the spring and establishing a strong foundation for operational performance throughout the year. Give your crop the best chance to thrive while mitigating risks at the same time.
The Wishek 842NT helps create an ideal seedbed by cutting and mixing the upper soil profile in the fall, incorporating heavy residue for fast decomposition, and managing the soil profile in heavier soils. Its heavy weight and blade spacing ensure thorough soil mixing and penetration in tough conditions.

The Wishek 842NT can be used in the fall to cut and mix the upper soil profile and incorporate residue for fast decomposition. It produces larger clod sizes that help to catch moisture and resist wind erosion over the winter. In the spring the field can be worked more easily with a secondary tillage pass to create an ideal seedbed.
The heavy weight and high strength of the Wishek 842NT allows it to penetrate and maintain depth in some of the toughest ground conditions. This helps it to mix large amounts of soil for incorporating heavy residue with excellent soil-to-residue contact. The soil microbes can then work more effectively, helping to decompose the residue at a faster rate.
Farmers with heavier soils may find benefit in using a heavy disc to cut and mix the upper soil profile to create better tilth. The Wishek 842NT offers approximately 1,488 kg/m (1,000 lbs/ft) of implement to help penetrate hard soils. It also has 28 cm (11 in) blade spacing, which is designed to provide thorough soil mixing to achieve this tillage objective.
The Wishek 842NT is a tandem disc designed to excel in challenging soil conditions, offering industry-leading weight and large concave discs for superior performance. Its heavy build allows it to penetrate hard ground and manage heavy residue, while the large discs ensure thorough soil mixing and optimal tillage depth.
The Wishek 842NT weighs approximately 1,488 kg/m (1,000 lbs/ft) of implement. This allows it to penetrate hard ground and heavy residue conditions. It can also maintain depth well to help ensure consistent tillage results.
The Wishek 842NT can be equipped with 71 cm (28 in) or 76 cm (30 in) concave discs with smooth or notched blades. The large diameter helps to mix high volumes of soil at depths up to 19 cm (7.5 in). The notched option offers better cutting performance when sizing heavy residue or slicing into hard ground.

Discover the strengths and features of Wishek 842NT tandem disc. Watch the video now to learn more about what makes Wishek 842NT unique.
The Wishek 842NT is equipped with specialized scrapers to prevent mud build-up, ensuring consistent operation in demanding conditions. Additionally, the disc offers convenient leveling options with manual or hydraulic systems, enhancing ease of use and operational efficiency.
The Wishek 842NT is equipped standard with specialized scrapers for the blades, bearings and spools. These scrapers help optimize performance of the disc by keeping the gangs free of mud build-up.
With the Wishek 842NT the discs can be levelled front-to-back manually with leveling screws, offering easy adjustment. For added convenience, an optional hydraulic system allows operators to make this adjustment from the cab.
The Wishek 842NT is a tandem disc featuring spring-cushioned gangs that protect the disc from damage by allowing discs to move and avoid solid objects. Additionally, the rear feathering discs ensure an even soil profile by eliminating ridges created by the front gangs, resulting in a uniform and precise soil finish.
Spring-cushioned gangs on the Wishek 842NT help prevent damage. When the blade strikes a solid object such as a rock, it travels in an arc of 15.2 cm (6 in) rearward and 15.2 cm (6 in) upward for a total of 30.5 cm (12 in), letting it travel over and avoid damage from impact with that object.
To help create an even soil profile, the Wishek 842NT is equipped with rear feathering blades to remove ridges created by the front gangs.
Optional single-point depth control allows the operating depth of the entire disc to be adjusted with a single setting. This simple adjustment, done at the front of the machine, is easy, safe and precise.
A rear hitch allows finishing tools or other items to be towed behind the Wishek 842NT. Hydraulic and electronic extension packages are available to allow articulation of towed implements.
The Wishek 842NT has a 10.2 x 20.3 x 1 cm (4 x 8 x 3/8 in) tubular welded frame offering rugged durability and the necessary weight to penetrate tough ground. This robust construction ensures the disc's longevity and reliable performance.
Are you looking for a machine with larger disc spacing for deeper soil penetration? The Wishek 862NT, with its 33 cm (13 in) disc spacing and 76 cm (30 in) discs with smooth or notched blades, is designed to tackle tough soil conditions and manage heavy residue efficiently.
Concave disc blades are designed to mix soil and residue efficiently. The implement’s heavy frame helps penetrate hard ground and maintain consistent tillage depth, even in the most challenging applications.
Smooth concave disc
Smooth concave discs are available in two sizes: 71 cm (28 in) and 76 cm (30 in). For a working depth of 23 cm (9 in) and better soil penetration, opt for the 71 cm (28 in) discs. For deeper cultivation with a working depth of 25 cm (10 in) and longer blade life, choose the 76 cm (30 in) discs. Plain blades are the best option for a smooth cut, making them ideal for finishing already worked soil.
Notched concave disc
Notched concave discs are available in two sizes: 71 cm (28 in) and 76 cm (30 in). For a working depth of 23 cm (9 in) and better soil penetration, opt for the 71 cm (28 in) discs. For deeper cultivation with a working depth of 25 cm (10 in) and longer blade life, choose the 76 cm (30 in) discs. Notched blades provide good grip in heavy residues and better penetration ability, making them ideal for breaking new ground and working in moist conditions.
A rear hitch allows finishing tools or other items to be towed behind the disc. Hydraulic and electronic extension packages are available to allow articulation of towed implements.
