Residue management tillage has become one of the necessities of higher yields. Heavy residue, particularly corn residue can negatively impact next year’s crop in many ways. Heavy residue remaining in the spring will insulate the soils keeping them cold and wet further into planting time and delay planting. Today’s high yielding varieties are producing residue in volumes beyond the ability of planter attachments to effectively move it sufficiently that it won’t endanger the crop emergence in the planted row by being blown back over the row. The growing popularity of corn on corn farming demands this material be sized and incorporated in to the microbial zone of the soil. The 1436 series Sunflower disc has been designed specifically for this task. The heavy frame, twenty degree front disc gang angle and full concavity blades form an aggressive alliance to slice through the thickest mat of BT corn residue to mix residue and soil into the microbial zone creating the best environment for residue breakdown. With operating widths from 21 to 35 feet, the 1436 can match almost any size farming operation.
The 1436 Series Tandem Disc Harrow is heavier and more aggressive than its predecessor. This new series is designed to deliver the performance demands of today’s farming. The new frame design of the 1436 is crafted with more structural strength and thicker walled tubing. It is accurately balanced to accommodate the heavy reeled finishing attachments popular today. The larger tires, wheels, hubs and spindles of the 1436 enhance the tool’s ability to move from field to road with ease. The improved carriage of the 1436 provides superb flotation in the field and added stability in transport. These new disc harrows are available in “True Cutting Widths” from 20’ 5” to 35’ 4”.
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.
