2026 SUNFLOWER 1234-29

SUNFLOWER - 1234-29 - THREE-SECTION TANDEM DISC HARROWS — UNIFORM FLEXIBILITY WITH UNMATCHED PENETRATION FROM A MEDIUM WEIGHT DISC The model 1234 Disc Harrow is a medium weight disc that capably handles primary through finish discing operations. An all welded frame features even weight distribution for uniform penetration, and the three flexible sections assure that rough, rolling and terraced ground will be tilled evenly and smoothly. Large tires provide excellent flotation, unmatched depth control and the base for level discing. Like all Sunflower discs, the 1234 is loaded with features that give it a definite edge over competitive brands. These features will save you time and enable the 1234 to always provide a level job of discing, regardless of terrain, discing depth, and/or soil condition. FEATURES • A medium weight disc that capably handles primary through finish discing • Three-section design ensures a level job of discing regardless of terrain • C-Flex™ bearing standards absorb disc gang shock and prolong bearing and frame life • Self-aligning Trunnion gang bearings feature triple lip seals that cannot be damaged by daily greasing • Overlapping disc gangs prevent ridging in the center • Self-leveling hitch simplifies leveling the disc from front to rear • Front mounted depth control adjusts the operating depth of the entire machine • Widths available from 18' to 32' • Safety light kit and SMV sign are standard equipment 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. C-FLEX™ BEARING ARMS The C-Flex bearing arms absorb disc gang shock created by stumps, rocks and normal discing, 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. 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. 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. MAINTENANCE-FREE LIFT SYSTEMS Sunflower discs are equipped with maintenance-free lift systems that 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 most models. 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. 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. WALKING TRIPLE TANDEMS Center-section walking triple tandems have 50% more weight-carrying capacity than conventional walking tandems. 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. DISC HARROW ATTACHMENTS THREE-ROW HD COIL TINE HARROW The HD harrow has 1/2" x 22" heavy-duty tines on 12" centers, creating a 4" overall tine spacing. The configuration has 12" spacing between rows for better residue flow. Adjustable spring loaded mounting arms provide the necessary down pressure. THREE-ROW SPIKE DRAG HARROW The three-row spike drag features independence of each bar, allowing maximum conformance to irregular terrain. Its weight provides the aggressive action necessary to handle tough soils while the 1" spikes on 1-3/4" centers effectively complete the seedbed and incorporation process. REAR-TOW HITCH Several rear-tow hitch options are available.
