Farm King tandem discs are built to handle trash and incorporate heavy residue. Using a one of a kind floating hitch, Farm King tandem discs leave a more level finish when compared to competitive units. All Farm King disc gangs are torqued to an unparalleled 3,200 ft-lb of torque. Steel fabricated spools are built to withstand heavy shock loads and prevent gangs from slipping. Farm King discs are also built using the best bearings in the industry, so you stay in the field until the job is done.

Standard Rigid Hanger
Heavy built rigid bearing hangers hold strong in the most extreme conditions. The slimline hanger design is contoured for best residue flow through the gangs. Models 4490 and 4590 hangers are formed 5/8' solid steel and reinforced for additional strength. 6650/ 6650-LTF, 8700 and 8700-LTF models use hangers constructed from 1-1/4' welded steel. All hangers are u-bolt mounted to the gang beams for ease of adjustment. Stone-Flex hangers are available as an option on all Tandem Disc models.

Blade Scrapers
All Farm King discs feature one piece, 4' wide blade scrapers made of carbon steel for long wear life. The scrapers are U-bolt mounted for maximum adjustment on a heavy-duty tubular steel bar. The leading edge of each scraper is located near the center of the blade for maximum crop residue flow and to reduce draft requirement.

Staggered Front Gangs
Staggered, overlapping front gangs are standard (except for Model 395) and ensure that all soil at the center of the disc is cut out cleanly and evenly eliminating the need for a center shank or bulk buster.

Transport
Standard hydraulic lockout valves prevent accidental operation of either the lift or wing cylinders when the disc is being transported. Low transport fold models 6650LTF and 8700LTF have a transport height of 14' (4.3 m).

Removable Spindle Axles
Farm King tandem discs are built with maintenance concerns in mind. All spindle axles are designed for easy removal and maximum strength. Each spindle is bolted into a sleeve and can be removed by simply removing the bolt and pulling out the axle. This will save valuable time if repairs to a tire are needed.

Steel Fabricated Spools
Farm King discs feature fabricated steel half and full spools. Unlike ductile cast spools, steel spools can withstand far greater “shock loads” from rocks or stumps thereby eliminating spool breakage. Compressed to maximum density prior to assembly, Farm King’s fabricated spools ensure the gang will not shift and become loose.

Furrow Filler Blades
In order to get the most uniform and consistent field finish, Farm King tandem discs have furrow filler blades as standard equipment. The first are 4' smaller than the working blades and the second set are 8' smaller. These blades work with the full sizes blades to create a uniform well-worked field.

Rephasing Hydraulic Lift System
Depth stop segments are supplied with each disc to ensure continuous same-depth tilling. Each of the wing frames can be easily leveled using a conveniently located eye-bolt adjustment. Cylinder arms on each of the rockshafts are equipped with replaceable hardened wear bushings for prolonged trouble free performance.

Tandem Walking Beam Axle
Standard equipment on the main frame, each walking beam pivots on greaseable bushings to improve weight distribution and stability when being transported.

Large Gang Shaft
All Farm King discs feature a large 1-15/16' diameter, high carbon steel gang shaft. This gang shaft along with Farm King’s steel fabricated spools allows the gang assembly to be torqued at the factory to 3200 ft-lb.

Interlocking Half Spool
This exclusive Farm King feature ensures that each bearing sleeve interlocks with adjoining half spools to provide positive drive to blades and reduces possibility of blades turning on the gang shaft. Optional with 26' blades, standard with 28' and larger (available on 10.5' and 12' spacing only).

Stone Flex Hanger
For those who want additional protection, stone flex hangers are available as an option. With the extreme thrust forces present on a disc and potential for large rocks in some areas, the stone flex hanger is a perfect choice for absorbing shock loads. The C-shaped spring steel reacts to both vertical horizontal forces. Disc blade penetration is not compromised.
