Exceptional penetration in tough ground 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 862NT. Weighing in at approximately 1,000 lbs/ft of implement, the Wishek 862NT is a tandem disc with 13 in disc spacing that performs in some of the toughest ground conditions, and its durable design has a reputation for lasting many years.
Breaking heavy ground
Because it has such a high weight per blade, the Wishek 862NT is a top choice for breaking new ground. It penetrates tough soil conditions better than lighter discs.
Extreme residue management
The Wishek 862NT has extra-large concave discs that are engineered to turn over large amounts of soil. It helps bury heavy residue for faster decomposition.
Soil mixing
In tough ground conditions, the Wishek 862NT can help break up and mix the hard upper soil profile for easier management and better seedbed preparation in the spring.
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.

Leveraging weight to penetrate ground
An exceptionally heavy frame, combined with 13 in disc spacing, helps to produce an industry-leading weight per blade. This weight is leveraged to help penetrate and maintain depth in hard soils. As a result, the Wishek 862NT is commonly used to break new ground, since it can penetrate and turn over sod better than most other tools.
-
Bury extreme residue for fast decomposition
With a maximum working depth of 7.5 in, the Wishek 862NT is a tandem disc that turns over more soil than most other discs. This action helps to bury large amounts of residue and create excellent soil-to-residue contact. The soil microbes can then work more effectively, helping to decompose the residue at a faster rate.
-
Managing hard soil profiles
Hard ground conditions can cause problems with seedbed preparation and planting. The Wishek 862NT can be used to break up and mix the soil profile at working depths up to 17.5 in. It produces larger clods that help catch moisture and resist wind erosion over the winter. The clods can then be broken down easily in the spring with a secondary tillage pass, helping to form a planter-ready seedbed.
Exceptional performance in tough soil conditions
The Wishek 862NT tandem disc is engineered to excel in difficult soil conditions, featuring industry-leading weight and large concave discs for outstanding performance. Its robust construction enables it to penetrate hard ground and handle heavy residue, while the large discs ensure thorough soil mixing and optimal tillage depth.
Industry-leading weight per blade
The Wishek 862NT weighs approximately 1,000 lbs/ft of implement. Its 13 in disc spacing provides ample weight per blade to help the unit penetrate the soil when breaking new ground or in other challenging conditions.
Excellent mixing with large concave discs
The Wishek 862NT counts with 30 in diameter 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 862NT
Improved performance and user convenience
The Wishek 862NT is a tandem disc that features specialized scrapers that prevent mud build-up, ensuring reliable operation in challenging conditions. Additionally, it offers convenient leveling options with either manual or optional hydraulic systems, enhancing user convenience and operational efficiency.
Scrapers prevent mud build-up
The Wishek 862NT 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 Leveling Screws
With the Wishek 862NT the discs can be leveled 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 862NT is a tandem disc equipped with spring-cushioned gangs that protect the discs from damage by allowing them 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 862NT 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 862NT 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 862NT. Hydraulic and electronic extension packages are available to allow articulation of towed implements.
Durable heavy tubular frame
The Wishek 862NT 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 842NT for smaller disc spacing
Do you need a machine with smaller disc spacing for finer soil breakdown? The Wishek 842NT, featuring 11 in disc spacing and discs available in 28 in and 30 in sizes, offers excellent residue management and a level soil profile.
