Four-Section Flexibility Follows Contours Like No Other

The model 1444 disc by Sunflower features four section flexibility for unmatched ground hugging capabilities. The unique linkage system allows each half of the unit to function independently, not only from side to side, but also from front to rear. Now newly redesigned with grease-free transports and wing hinges, the 1444 is designed to save you time and increase your productivity. Consider the flexibility of the 1444 from Sunflower, it will provide you with unmatched performance in rolling terrain or terraced ground and provide the extra protection needed in rocky soils.

Staggered Overlapping Disc Gangs

 

With the exception of the 1300 , 1700 and 1800 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.

Trunnion Mounted Bearings

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.

C-Flex™ Bearing Standards

 

 

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.

Spring Cushion Gang Assembly

 

 

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

Front-mounted Gauge Wheels

A trademark on all flexible Sunflower discs 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 5-bolt hub and 8.00 x 10 ply tire.

Variety of Disc Blade Diameters

 

Sunflower offers a variety of disc blade diameters, thickness and spacing to allow you to select the best combination for your farming operation. 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" to 2 1/2” diameter round stress proof gang shafts and factory assembled gangs are torqued hydraulically to approximately 1,500 pounds. Spring end collars (all except 1700 & 1800 series) on each end of the gang are collapsed slightly and make sure the gang stays tight. This results in thousands of trouble free acres.

 

Notched blades available on 1700 & 1800 series

Maintenance-free Lift Systems

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

 

Maintenance Free Wing Hinges

 

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