Exclusive 4-Step Process
1.Capture and Slice: Excalibur® VT (Vertical Tillage) blades, with their distinctive scalloped edge, capture and slice residue into planter-manageable sizes. This exclusive, 32-flute design easily penetrates soil, creates small clod size and begins the soil and residue mixing process.
2.Cut and Remove: In this high-speed process, adjustable gang angles with Excalibur VT blades (on 8” spacing), remove the maximum amount of uncut soil at shallow depth settings, while minimizing furrowing and ridging for a smooth field finish. The adjustable gang angle gives you the choice to move soil laterally or to leave more residue.
3.Mix and Anchor: Exclusive to KUHN Krause, rotary Star Wheel™ treaders aggressively mix soil and residue, pulverize large clods, remove soil from disturbed root balls and anchor residue into the soil surface.
4.Size and Firm: The proven 24/7® soil conditioning reel delivers clod sizing and firming for this high-speed operation.
Adjustable Gang Angles
Soil movement and residue mixing are varied by adjusting the gangs from 1° (maximum residue retention) to 5° (maximum soil movement, leveling and residue mixing). Hydraulic gang angle adjustment is available as an option. Excalibur VT blades are designed to wear on both sides of the blade at these settings, maintaining a sharp edge over time. These shallow angles prevent soil roll and inversion, distinguishing the Excelerator’s performance from competitive units based on older disc harrow technology with typical gang angles from 10° to 22°.
Excalibur® VT Blade Spacing
The second gang of Excalibur VT blades are indexed to the front 8” spaced blades to remove the maximum amount of uncut soil at shallow depth settings. This provides uniform tillage without smearing or compacting the critical seed zone required for consistent seedling root development. During this process, soil and residue are lifted above the surface and propelled by the fluted blades into the next step of this exceptional vertical tillage process. The unique design of the Excalibur VT blades minimizes furrowing and ridging, leaving a smooth field pass-to-pass.
Exclusive Star Wheel™ Treaders
Aggressively mix soil and residue, pulverize large clods, level and anchor residue into the soil surface. This action protects residue from blowing winds or washing rains, and begins the decomposition of residue into valuable organic matter.
The Star Wheel treaders assist in breaking out any remaining uncut soil between blade paths providing a smooth, even surface for planter row units to place seeds consistently in the seed zone. Constant flow hydraulic-adjustable gangs are spring cushioned to contour over varying field conditions, evenly distributing residue across the soil surface for a uniform finish.
Heavy-Duty 24/7® Conditioning Reel
The proven 24/7 soil conditioning reel delivers clod sizing and firming for this high-speed operation. The 24/7 reel also offers the convenience of “floating” with a simple in-field adjustment, allowing continued operation in higher soil moisture conditions. Two heavy-duty reel options are available. Choose flat blades for maximum clod sizing in hard soil conditions or round bars for increased soil firming in loamy soil conditions, this effective component completes a superior finish to any field.
