Exceptional residue management in tough conditions
Whether breaking sod, turning over heavy residue or performing any other job requiring a heavy disc, count on the industry’s workhorse — the Wishek 842NT. Weighing in at approximately 1,000 lbs/ft of implement, the Wishek 842NT is a tandem disc with 11 in disc spacing that performs in some of the toughest ground conditions, and its durable design has a reputation for lasting many years.
Primary tillage for spring preparation
Seedbed preparation can be made easier in the spring by running the Wishek 842NT as a primary tillage pass in the fall.
Efficient heavy residue management
The Wishek 842NT is a tandem disc that offers excellent mixing performance to incorporate large amounts of residue for fast decomposition.
Superior soil cutting and mixing
Large concave 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.
Excellent agronomic performance
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 first step toward an ideal seedbed
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.
-
Incorporate heavy residue for fast decomposition
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.

Soil profile management
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 1,000 lbs/ft (1,488 kg/m) of implement to help penetrate hard soils. It also has 11 in (28 cm) blade spacing, which is designed to provide thorough soil mixing to achieve this tillage objective.
Superior performance in challenging soil conditions
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.
Penetrate hard ground with industry-leading weight
The Wishek 842NT weighs approximately 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.
Large concave discs provide superior mixing
The Wishek 842NT can be equipped with 28 in (71 cm) or 30 in (76 cm) concave discs with smooth or notched blades. The large diameter helps to mix high volumes of soil at depths up to 7.5 in. The notched option offers better cutting performance when sizing heavy residue or slicing into hard ground.
A closer look at the Wishek 842NT
Enhanced performance and ease of use
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.
Scrapers prevent mud build-up
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.
Manual or Hydraulic Levelling Screws
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.
Protection and precision
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 for rock protection
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 6 in rearward and 6 in upward for a total of 12 in, letting it travel over and avoid damage from impact with that object.
Rear feathering blades eliminate ridges
To help create an even soil profile, the Wishek 842NT is equipped with rear feathering blades to remove ridges created by the front gangs.
Single-point depth control
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.
Versatile rear hitch
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.
Durable heavy tubular frame
The Wishek 842NT has a 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.
Choose Wishek 862NT for larger disc spacing
Are you looking for a machine with larger disc spacing for deeper soil penetration? The Wishek 862NT, with its 13 in disc spacing and 30 in discs with smooth or notched blades, is designed to tackle tough soil conditions and manage heavy residue efficiently.
