Sunflower introduced the first Flexible Offset Disc to the American farmer in 1968.
With over 40 years of disc building experience, Sunflower knows what it takes to make them work. Now two of the biggest names in the industry have come together to bring you the Sunflower line from Massey Ferguson®.
The Sunflower from Massey Ferguson Disc Harrows are capably of handling operations from primary through finish discing.
Model 1212 Disc Harrow is the discing answer for America's smaller farmers.
The 1300 Series disc is the best flexible Offset disc on the market.
The 1234 and 1435 Series discs are designed to save you time, improve your tillage pass and help you become a more efficient producer.
The Sunflower 1444 and 1544 Series discs features four section flexibility for unmatched ground hugging capabilities and the 1550 Series five section disc with a monster 50' working width is unsurpassed..
All Sunflower from Massey Ferguson discs are loaded with features that give a definite edge over competitive brands in acre consuming efficiency.
All spools, whether precision machined cast iron or precisely fabricated steel, provide a perfect fit between it and the disc blade, resulting in smooth free turning gangs. High strength 1 3/4" diameter round stress proof gang shafts and factory assembled gangs are torqued hydraulically to approximately 1,500 pounds.
Spring end collars on each end of the gang are collapsed slightly and make sure the gang stays tight. This results in thousands of trouble free acres.
A light kit is standard on all Sunflower equipment. Light kits have a flashing feature, turn signals and can be viewed from front and rear. SMV emblems are also standard.
All components except disc blades, scrapers, tires and hydraulic hose are covered for three years. If you trade the disc off prior to the end of the warranty period, the remaining warranty will transfer to the new owner.
This helps add resale value to your Sunflower from Massey Ferguson Disc.
Standard equipment on every Sunflower disc, the C-Flex™ bearing standards absorb disc gang shock created by stumps, rocks and normal discing. This extends the bearing, spool and disc blade life.
A bonus feature is the C-Flex's™ ability to clear residue better than conventional rigid standards. The C-Flex™ bearing standards also allow for easy maintenance of the disc gang assembly.
Just remove one bolt and loosen another bolt at each C-Flex™ location and the entire gang can be dropped. All C-Flex™ standards remain in place to assure the gang will be in the correct position when replaced.
Unlike competitive machines the scraper bars are mounted to the back of the C-Flex Standards. This allows the scrapers to react with the gang and not come into contact with the spools or blades
The heavy-duty gauge wheels feature a 5-bolt hub and 8.00 x 10 ply tire.
Level the disc frame from front to rear with Sunflower's unique 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.
Sunflower discs are equipped with maintenance-free lift systems. These systems pivot on space-age UHMW polymer sleeves eliminating greasing (except on 1211 & 1300 series).
With the exception of the 1300 Offset Series, every Sunflower disc features staggered overlapping disc gangs - one of the keys to level discing.
The overlapped placement of the front gangs cuts all of the ground cleanly while the staggered rear gangs throw the soil back in a criss-cross pattern.
This arrangement eliminates the need for a chisel shank or bulk buster typically required in the center and behind the front gangs of conventional tandems. Even more importantly - the Sunflower combination eliminates ridging in the center - another problem common with conventional tandem discs.
Sunflower also makes sure the tires are placed close to the hinge line on the center section and the outside of each wing. This assures the disc will perform properly, without gouging, in rough or terraced ground. Some manufactures save money by simply extending the gang bars on the wings to make the next large size. This leaves the wing wheels too far inside and they cannot control the wings in rough or terraced ground.
Sunflower's trunnion bearings provide positive alignment, eliminate wear between the bearings and the housing and ensure positive lubrication. As the C-Flex™ bearing standards move, the gang bearings have to constantly realign. On conventional bearing systems the bearing moves within the housing. This eventually leads to wear between the bearing and the housing... then bearing failure, because grease cannot get into the bearing. With the trunnion bearing there is never any wear between the bearing and the housing and there is always positive lubrication. 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.
