Versatile Secondary Tillage Implement

In today’s farming economy, it’s all about getting more done in a day. Recognized as one of the most productive tillage tools in the industry, the Great Plains Disc-O-Vator® can disk, cultivate, harrow, and incorporate herbicide—all in a single pass.

Known for its robust strength, the Disc-O-Vator’s rugged frame is engineered to flex and hug rolling terrain. The Disc-O-Vator also features the Max-Mix™ shank pattern, which increases chemical incorporation, reduces windrowing, and helps eliminate banding. Shanks are spaced at 7" with 9" sweeps to ensure good cutout, and a rugged front gang design is offered with a choice of concave or Turbo blades on 8" spacing. This versatile secondary tillage implement works well behind a fall chisel pass because the front discs chop residue and smooth the field before sweeps run through the soil, which reduces plugging and bunching of trash.

The 8000 Series Disc-O-Vator® line is comprised of 12 models, with working widths ranging from 15' to 52'. Four of the models (DVN) are specifically designed for narrow transport and can be purchased in 15' to 24' versions. With a full line of options and finishing attachments, the Disc-O-Vator can be custom built to fit a diverse range of needs.

Features May Include:

Constant-Level Hitch

• Keeps implement level regardless of undulations in terrain.

Max-Mix™ Shank Pattern

• With a true four-bar design, shanks on the first and second bars are split by the third and fourth bars. On an effective 7" spacing, no shank is closer than 28" on any bar. The Max-Mix shank design evenly spreads residue and uniformly incorporates fertilizer or manure for even distribution. True, one-pass tillage eliminates the cost of owning several tillage tools.

Hydraulically-Adjustable Coulters

• This feature allows the depth of the coulters/discs to be changed independently of the shanks. It also enables the residue coverage levels to be adjusted on-the-go to meet government requirements on HEL ground.

Choose Your Shank & Sweeps

• Choose between heavy-duty K-flex shanks (shown) with 185 lbs. of point trip force, or spring-loaded Magnum shanks with 205 lbs. of point trip force. Sweep choices are either 9" regular or 9" hard-faced.

Choose Your Disc Blades

• Pick exclusive Turbo coulters (middle), rippled coulters (right) to size residue and run at faster ground speeds, or opt for 20" shallow-concavity discs (left) to feather worked soil into ruts and wheel tracks.

Rebound Valve and Single-Point Depth Control

• The highly efficient hydraulic rebound valve provides precise operating depth and keeps the machine running level, which extends the life of the entire hydraulic system. The pressure-reducing valve limits hydraulic cylinder pressure, and the counter-balance valve prevents air from passing through seals and into the system. This valve shines in fields where the machine needs to be raised and lowered numerous times.

Optional Knock-On Sweeps

• Quick-change system for installation and removal of sweeps. Once installed, the sweeps can be changed without the use of power tools.

Optional 3-Bar Coil Tine & Reel

• Provides a medium level of soil finishing, effectively distributing surface residue.

Optional 3-Row Spike & Reel

• Residue distribution and leveling, plus the firming aspects of a finishing reel.

Optional 4-Bar Coil Tine

• Additional coil tines increase soil finishing and residue distribution.

Optional 5-Bar High-Residue Spike

• Five rows of 14" staggered teeth break up clods and level high-residue field conditions.

Optional 7-Bar Spike

• Featuring 7 rows of staggered ¾" x 14" spikes; most aggressive.
