Trunnion-Mounted Bearings
The trunnion bearing features triple-lip seals that cannot be damaged by daily greasing and metal washers that protect the seals from being damaged by stocks or material wrapping around the gang shaft. As the C-Flex bearing standards move, the gang bearings constantly realign. There is never any wear between the bearing and the housing, always creating positive lubrication as a result.

 C-Flex Bearing Standards
Sunflower’s trunnion bearings provide positive alignment, eliminate side-loading of the bearings and the housing to ensure positive lubrication. As the C-Flex bearing standards move, the gang bearings have to constantly realign.

Single-Point Depth Control
Single-point depth control is conveniently located at the front of the machine for easy access. Large, easily read markings indicate the direction of movement for adjusting.

 Front-Mounted Gauge Wheels
A trademark on all flexible Sunflower tools is front-mounted gauge wheels. This important feature prevents the front gangs of the wing frame from gouging, buckling or cutting deeper than the other gangs, promoting a level, ridge- or furrow-free field. The heavy-duty gauge wheels feature a five-bolt hub and 8x10 ply tire.

Hydraulic Self-Leveling Hitch
Level the disc frame from front to rear with Sunflower’s hydraulic self-leveling hitch. This positive adjustment maintains a preselected setting regardless of the tillage depth. It features heavy-duty compression springs on each side of the pivot to cushion both front and rear gangs, which is important when crossing ditches or rough terrain.

Maintenance-Free UHMW
Sunflower 6630s are equipped with maintenance-free lift and wing pivot systems. These systems pivot on UHMW polymer sleeves, eliminating greasing in the lift, wing and gauge wheel pivots.
