Sunflower field cultivators
Sunflower field cultivators feature superior engineering and rugged construction that withstand the test of time. A prime example of this superiority is the A-frame tongue design, which adds tremendous support to the center-section frame to withstand the rotational forces generated by the heavy point load shanks and the combined weight of multi-section tools when folded for transport. Each leg of the A-frame tongue extends deep under the center-section frame, supporting it from the tractor drawbar to the lift axles.

Outstanding ground clearance and superb flotation.

The truss-style frame on the 5056 provides the strength required by today’s high-horsepower tractors. The computer-aided design, utilizing Finite Element Analysis, ensures the product will stand up to the stresses of difficult soil and terrain conditions. Deep frames and optimum shank placement account for unmatched residue flow through the tool. The single-point depth control, rephasing lift system, shanks with either spring-tension (190 lb. point load) or S-tine design (160 lb. point load) and heavy-duty walking tandems with large-diameter slip-in spindles are all covered by Sunflower’s three-year limited warranty. Choose between the standard self-leveling and the optional floating tongue (for hilly or undulating terrain) to maintain the same level operating position.
