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.
