Features

WALKING TANDEMS
The walking beam pivot assemblies consist of two tapered roller bearings with triple-lipped seals. For ease of service and strength, the wheel spindles slip into the spindle tube, which is welded into the walking beam.

PATENTED C-FLEX MOUNTS
Our patented C-Flex bearing standards absorb disc shock created by rocks, field obstructions and normal discing. Additional C-Flex benefits include the ability to clear residue better than conventional rigid standards; extended bearing, spool and disc blade life and easy maintenance.
Featured on all series.

HEAVY-DUTY FRAME
All Sunflower primary tillage tools feature an all-welded, box-beam frame with specially formed gussets in all high-stress areas for maximum reliability and a long service life. Most models also feature a maintenance-free lift system, which utilizes space-age UHMW plastic sleeves on lift pivots, to eliminate the need for greasing, while decreasing parts wear and maintenance.
Featured on all series.

RIGID SHANK MOUNT
The rigid shank holder features shear-bolt protection.
Available on all series.

MINIMUM DISTURBANCE SHANK
