Features

TRUNNION MOUNTED BEARINGS

Sunflower’s trunnion bearings provide positive alignment and eliminate side-loading of the bearings along with the housing to ensure positive lubrication. The trunnion bearing features triple-lip seals that cannot be damaged by daily greasing. Metal washers protect the seals from being damaged by stocks or material wrapping around the gang shaft.

Featured on all except 1700 and 1800 series.

C-FLEX™ BEARING ARMS

The C-Flex bearing arms absorb disc gang shock created by stumps, rocks and normal disking, which extends the bearing, spool and disc blade life. They also clear residue better than conventional rigid standards and allow for easy maintenance of the disc gang assembly. Unlike on competitive machines, the scraper bars are mounted to the back of the C-Flex arms, which allow the scrapers to react with the gang and not come into contact with the spools or blades.

Featured on all except 1700 and 1800 series.

SELF-LEVELING HITCH

Level the disc frame from front to rear with Sunflower’s self-leveling hitch. This positive adjustment maintains a pre-selected 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, important when crossing ditches or rough terrain. Some disc models offer optional hydraulic adjustment.

Featured on all series.

FRONT-MOUNTED GAUGE WHEELS

All flexible Sunflower discs have 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.

Featured on all winged units except 1700 and 1800 series.

MAINTENANCE-FREE LIFT SYSTEMS

Sunflower discs are equipped with maintenance-free lift systems that pivot on space-age UHMW polymer sleeves, eliminating greasing.

Featured on all except 1700 and 1800 series.

MAINTENANCE-FREE WING HINGES

Maintenance-free wing hinges that utilize the same UHMW technology as the lift systems are used on most models.

Featured on all except 1300, 1700 and 1800 series.

SPRING-CUSHION GANG ASSEMBLY

The entire gang assembly pivots upward when an obstruction is encountered. The heavy coil springs compress, allowing the gang assembly to pass over the obstruction, then expand to return the gangs to their working position.

Optional on 1700 & 1800 series. The rigid gang assembly is standard equipment on the 1700 and 1800 series.

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 of all configurations—dual, tandem or triples—slip into the spindle tube, which is welded into the walking beam.

Featured on all except 1212 series.

WALKING TRIPLE TANDEMS

Center-section walking triple tandems have 50% more weight-carrying capacity than conventional walking tandems.

Featured on 1550 series.

VARIETY OF DISC BLADE DIAMETERS

Sunflower offers a variety of disc blade diameters, thickness and spacing allowing operators to choose the best combination for their unique farming operation. All spools, whether precision-machined cast iron or precisely fabricated steel, provide a perfect fit with the disc blade, resulting in smooth, free-turning gangs. High-strength 1 3/4-inch- to 2 1/2-inch-diameter stress-proof gang shafts and factory-assembled gangs are torqued hydraulically to approximately 1,300 pounds. Spring-end collars (all except 1700 and 1800 series) on each end of the gang are collapsed slightly to make sure it stays tight.

Notched blades available on 1700 and 1800 series.

 

  • Each half of unit functions independently
  • C-Flex™ bearing hangers absorb disc gang shock and prolong bearing and frame life
  • Narrow tongue allows much shorter turning radius
  • Capable of primary through finish disking operations
  • Independent front to rear leveling is simple with conveniently located self leveler
  • Single point depth control on each center section allows you to fine tune the disc for optimum performance
  • Walking tandems on the wings and center sections prevent frame bounce and uneven penetration
  • Safety light kit and SMV sign are standard
