Frame

The main frame of the 4412 Series is constructed of 6” x 4” x 3/8” steel tubing and is reinforced in all the high stress areas. Wheel lifts rotate on maintenance-free bearings (UHMW material) and lift tubes are supported by multiple frame members for maximum support. Sunflower pioneered the use of Ultra High Molecular Weight material in the lift system of the SF1433 tandem disc harrow way back in 1994. This material excels in this application because it virtually eliminate friction and wear. Under a microscope it can be seen that the steel tube surface is inlaid with microscopic pores. These pores fill with UHMW material after a few rotations of the lift tube. Once filled the steel surfaces and now simply one UHMW surface rotating on another and wear is virtually eliminated.

Shanks

The Auto-Reset shanks have a 3500 lb. trip setting and can trip vertically sixteen inches when an obstruction is encountered. The shank assembly is protected by a shear bolt in the shank mounting. Operators may select from two working ranges with maximum depths of 14 or 18 inches. The deep till parabolic shanks are evenly dispersed on the frame form front to rear providing exceptional material flow though the tool.

Individually Mounted Front Blades

Three different angles are combined to create the most aggressive single gang assembly in primary tillage. In this patented equation the gang beam is attached to the frame at twenty-two degrees, the C-Flex bearing arms which hold the blade hubs are formed at eighteen degrees and the blade spindles are set at eight degrees above level. The spindle angle is to counter the heavy draft of the soil and necessary to maintain the position of the blade at the correct angle to effectively size residue and invert soil.   Each blade assembly of the front gang is equipped with a two piece shield. The shields control the flow of material between the blades and through the gang to avoid plugging.

Rear Gang Assembly 

All gangs are mounted to the main frame with parallel linkages to maintain the blade angle throughout the gang’s range of depth adjustment. The rear gangs are assembled on heavy 1-3/4” alloy steel arbor bolts. Spring steel washer and gang nuts on each end keep the assemblies tight. The staggered and overlapping gang design of the 4412 ensures uniform tillage across the width of the tool and level output. The rear gangs of the larger model fold hydraulically producing a narrow transport.
