The Spyder is a purpose-built disc drill for stripped straw, heavy residue, and low-disturbance seeding. Its patented Gent Undercut opener system uses a 17-inch lead blade at a precise 22.5-degree angle to cut through dense residue mats and place seed directly into moisture — without the hairpinning, sidewall fracturing, and plugging that show up when conventional disc drills hit their limits.

Why operators switch to the Spyder

Five areas where the Spyder was engineered differently from drills that were adapted from another platform.

Spyder disc drill moving through heavy residue in field

Better residue flow

Heavy standing stripped straw and damp residue mats get trapped between closely packed steel brackets and low-hanging structures, causing plugging, bunching, and material buildup.

The Spyder Solution

An open row-unit layout with fewer obstruction points allows residue to move through the machine instead of building up and stalling the discs or entire machine. Row-unit clearance and removal of pinch points helps heavy residue and biomass continue flowing under difficult field conditions.

  • Open-architecture row-unit layout
  • Fewer material catch points
  • Maximized row-unit clearance
  • Designed for stripped straw and heavy biomass
Gent Undercut Opener cutting through residue

Consistent penetration. Reduced hairpinning.

Standard disc drills often push residue into the seed slot instead of cutting through it cleanly, especially in heavy residue mats and changing terrain.

The Spyder Solution

Heavy residue mats expose the weakness in many disc drills. The patented Gent Undercut opener system uses a 17-inch lead blade positioned at a precise 22.5-degree angle to stay engaged in the residue mat while frame weight, mechanical downforce, and 34 inches of opener travel maintain penetration into moisture through washouts, hilltops, terraces, and uneven field conditions.

  • Patented Gent Undercut opener system
  • 17-inch lead blade
  • 22.5-degree opener angle
  • 34 inches of vertical opener travel
  • Mechanical downforce with in-cab adjustment
Low disturbance seeding preserving surface residue

Low disturbance. Locked-in moisture.

Throwing soil and fracturing sidewalls dries out the seed zone and disrupts the residue layer protecting moisture.

The Spyder Solution

The Gent Undercut opener uses a 17-inch lead blade paired with a 15-inch trailing blade to cut a narrow furrow profile — placing seed directly into moisture without displacing soil sideways or fracturing the seed zone walls. A trailing packer wheel immediately seals the furrow for consistent seed-to-soil contact.

Each opener is mounted on a dedicated trailing pivot, allowing the row unit to steer naturally through curves and uneven terrain while providing lateral rock relief.

  • 17-inch lead blade with 15-inch trailing blade
  • Narrow furrow profile
  • Immediate furrow sealing with packer wheel
  • Surface residue preservation
  • Trailing pivot opener design

Unmatched access. Simplified maintenance.

Routine maintenance on most disc drills requires blocking the machine up or crawling into tight row-unit spaces to access wear components.

The Spyder Solution

Higher frame clearance creates more working space around the row units. A patented Service Mode shifts the rear section back from the in-cab touchscreen, creating dedicated access to the opener assemblies without blocking up the machine. It's the only system of its kind on a disc drill.

The Ownership Advantage

As the blades wear down, the 17-inch lead blade can be moved to the trailing hub to replace the 15-inch blade, providing 4 inches of usable blade wear.

  • Patented Service Mode for opener access
  • Higher frame clearance
  • Simplified opener architecture
  • 4 inches of usable blade wear
Spyder M-fold compact transport

Compact transport. Purpose-built geometry.

Moving large equipment between fields costs time. Most disc drills this size fold into a wide, tall transport profile that's slow on the road and awkward to store.

The Spyder Solution

The patented M-fold design gives the Spyder its name — and its transport advantage. On 60, 66, and 74-foot models, the M-fold delivers a more compact transport profile than any comparably sized disc drill on the market, typically fitting within the duals of the air cart.

The Ownership Advantage

Faster moves between fields. Less road width to manage. When the season is done, the M-fold geometry means the Spyder takes up significantly less shed space than a comparably sized disc drill.

  • Patented M-fold design on 60, 66, and 74-foot models
  • More compact transport than any comparable disc drill
  • Typically fits within the duals of the air cart
  • Less shed space required when stored
  • One-touch fold and unfold from the cab

Hitch Control

Manage hitch settings from the cab — without stopping.

Four operator-selectable hitch settings are controlled directly from the touchscreen monitor, allowing operators to adjust how the Spyder tracks and responds across varying terrain and field conditions.

Unlocked is the standard setting, allowing the hitch to move freely during normal operation and transport around the yard. Lock Mode increases hitch stability when backing up to the air cart or operating in steeper terrain.

Restriction Mode is designed for rolling and uneven terrain, limiting hitch movement to improve stability and reduce unwanted steering movement in changing field conditions.

Skew Correction Mode is available for specialized side-hill conditions where additional hitch correction may be required.

  • Four operator-selectable hitch settings
  • Cab-controlled through the touchscreen monitor
  • Lock Mode for backing up and added stability
  • Restriction Mode for rolling and uneven terrain
  • Adjustable hitch behavior for varying field conditions

Inter-Row Coulters

Independent mid-row fertilizer placement when conditions call for it.

Inter-Row Coulters

Independent mid-row fertilizer placement when conditions call for it.

Inter-Row Coulters (IRCs) place fertilizer between seed rows using offset double-disc openers — keeping nutrients out of the seed zone while maintaining compatibility with low-disturbance seeding systems.

When seeding pulse crops or applications where fertilizer placement isn't required, the IRC openers lift completely out of the ground from the cab — no manual disengagement, no stopping. The IRCs can also run independently of the seed openers for straight fertilizer banding.

  • Offset double-disc fertilizer openers
  • Mechanical depth stops
  • Liquid-ready configurations available

IRCs (Inter-Row Coulters) are available on i-designated models. They feature offset double-disc fertilizer openers with mechanical depth stops and liquid-ready configurations. IRCs lift completely from the cab when not needed and can run independently for straight fertilizer banding.
The 40' transports at 19' 2". The 60' and 66' transport at 19' 8" and 19' 7" respectively. The 74' transports at 24' 2".

The 60, 66 and 74-foot models use the patented M-fold design — delivering more compact transport geometry than any comparably sized disc drill on the market and typically fitting within the duals of the air cart.
The Spyder's open row-unit layout and patented GENT undercut opener are specifically designed for stripped straw. The 17-inch lead blade slices open the soil while the 15-inch trailing blade lifts it — creating a clean furrow that places seed into moisture without pushing residue into the trench. Operators running in stripped straw report far less hairpinning and plugging than with conventional disc drills.
The Spyder performs best in heavy residue, stripped straw, and low-disturbance systems where moisture preservation matters. It's been proven across a wide range of conditions.
