2026 Kuhn 5640 Field Cultivator 20

2026 Kuhn 5640 Field Cultivator 20

The 5640 field cultivator features five rows of shanks for exceptional residue flow, ideal for today’s high-yield cash crop environments. The shanks are precisely spaced at 6 inches and arranged in a split-the-middle pattern, ensuring thorough weed removal across the entire width. Additionally, it includes an innovative floating hitch design and a positive stop depth control, which together ensure consistent working depth, crucial for uniform germination and seedling emergence.

Features may include:

• The 5640 field cultivator provides increased residue flow through the five rows of shanks in high residue conditions.

• Uniform cultivation with the split-the-middle sweep pattern removes green growth leading to better seed-to-soil contact

• The 24/7® leveling systems create a smooth, level seedbed surface for optimum planter performance, providing consistent seed spacing and planting depth.

• The unique KUHN Krause floating hitch system accurately gauges the depth of tillage across rolling terrain, promoting rapid and uniform crop emergence. A consistent depth of tillage ensures uniform soil moisture around the seed zone, enabling seeds to absorb moisture evenly from the soil. This uniformity is essential for the synchronized emergence of seedlings, a key factor in achieving the highest possible yields. Traditional hitch systems fail to adapt to undulating terrain, digging too deep on crests and not deep enough in troughs, leading to irregular emergence and a direct impact on the ultimate yield potential.

• The first three ranks of shanks till the full sweep width, while the fourth and fifth ranks till the middles creating a split-the-middle sweep pattern

• Six-inch shank spacing provides maximum tillage action and uniform soil, residue and herbicide mixing

• Front-to-rear frame clearance of 139” allows the 5640 field cultivator to handle high volumes of residue.

• The floating hitch system of the 5640 model features up to 57% fewer wear points compared to traditional models, significantly reducing the risk of malfunctions during crucial seedbed preparation. This model adeptly contours over rolling terrain in the field and transitions to a stable, self-leveling configuration for transport. The innovative hitch design lifts the gauge wheels off the ground while moving, enhancing both stability and maneuverability. This is a notable improvement over conventional floating hitches, which often experience caster wobble and can lose stability at higher transport speeds.
