The KUHN Krause Landstar™ 6405 delivers excellent residue flow handling capability, soil mixing, conditioning and leveling in one pass. Exclusive Excalibur® VT blades size residue uniformly and minimize lateral soil movement to mix soil and residue without creating ridges. Exclusive Star Wheel™ treaders provide additional clod sizing, leveling and residue distribution. The 24/7® leveling systems increase yield potential through better seedbed condition and increase productivity with non-stop farming.

Your benefits

Exclusive 5-Step Process

Landstar_5StepProcess.png

Exclusive 5-Step Process

  1. Cut Residue
    Exclusive KUHN Krause Excalibur® VT blades with their 32-flute edge uniformly size residue for smooth flow through the machine. The gang, angled 8 degrees toward the rear of the machine, minimizes lateral soil movement to improve the leveling action of the shanks.
  2. Mix
    Cultivator shanks provide thorough mixing action, dislodge weeds and settle soil. The Landstar™ offers a choice of 7” spacing for smaller clod sizing and more residue coverage, or 9” spacing for maximum residue handling capabilities.
  3. Anchor Residue
    Exclusive Star Wheel™ treaders cut clods, dislodge soil from weeds and root crowns, level ridges and recover residue evenly distributing it in the seedbed and on the soil surface.
  4. Level Soil
    Tine or spike harrows provide excellent clod breaking and additional leveling action. Choose the harrow system that best fits your cropping practice.
  5. Enhance Seedbed Condition
    The exclusive 24/7® Soil Conditioning Reel, available in 3-row tine with reel or 3-row spike with reel, accomplishes final clod sizing and soil firming with the ability to select a range of constant down pressure or float position to extend the weather/tillage window.

Maximum Residue Management

ManageResidue.png

Manage Residue

Crop residue management is critical for a healthy, productive soil environment. Sized residue, properly mixed into the soil, minimizes soil compaction, releases stored nutrients and aids in moisture infiltration. Residue cover provides protection against soil erosion from heavy rainfall and high winds.

The front-mounted gangs on the Landstar™ are the beginning of this crop residue management process. The 8° gang angle and Excalibur® blades combine to minimize lateral soil movement. The exclusive 32-flute Excalibur blade uniformly sizes residue and begins the leveling process. The 9-1/8” blade spacing provides 24% more residue cutting force than competitive models with narrower blade spacing. Hydraulic disc gang depth adjustment is standard.

Maximum Residue Capacity

Residue, cut by the disc gangs, flows easily through the Landstar shanks. Weeds are undercut and uprooted. For fall-tilled or minimum-till conditions, choose the spring mount shank. For standing stubble or tougher soil conditions, choose the exclusive XT270 shank featuring a 270-pound point load.

Anchor Residue

The uniquely designed KUHN Krause Star Wheels aggressively mix soil and residue, pulverizing large clods while anchoring residue to the soil surface. This action protects residue from blowing winds or washing rains, and begins the decomposition of residue into valuable organic matter.

The 16" diameter, ductile iron Star Wheel™ treaders are mounted in pairs at a 25° angle with spring down pressure allowing them to contour over varying field conditions, evenly distributing residue across the soil surface for a uniform finish.

Equipment

Landsman_Landstar_DepthControl.jpg

Single-Point Depth Control

Single-point depth control allows fine tuning of working depth for precise seedbed conditions. The depth indicator is located on top of the tube for easy viewing.

GangDepthAdjustment.jpg

Gang Depth Adjustment

Hydraulic gang depth adjustment is spring cushioned to protect against rock damage and allows on-the-go depth setting from equal to or 5” above the sweeps. This allows tailoring of residue coverage for fragile and non-fragile crop residues.
WalkingTandemCob.png

Walking Beams

Walking beams allow for consistent working depth on rough ground and more stable road transport.
Reels_HDRound_HDFlat.png

Two Reel Options Available

Choose from two agronomic conditioner designs. The heavy-duty round spiral reel provides clod sizing and firming in mellow, loam-type soils, and offers better performance in wet conditions. The heavy-duty flat spiral reel provides aggressive clod sizing in hard or high-clay content soils.
GuardianHitch.png

Guardian Hitch™

This exclusive option guards against stress on the tractor drawbar and implement frame. Lateral drawbar forces are transferred through the hitch pivot where shock load from steering input is dampened by urethane blocks. Choose from the articulating ball Cat III, IV or V double-bolt, cast hitch, depending on model.
TractorInterfaceCenter.png

Tractor Interface Center

The tractor interface center prevents hydraulic hoses from binding in turns and adds operator convenience. Includes hose routing chart, color coded hose grips, storage for light hookup and owner’s manual.
