The Super Duty Model 4600 Disc stands in a class by itself. Available in a range of sizes from 24½ft. to 42½ft. This massive unit boasts an average weight per foot of 700lbs; a definite match for any of today’s most powerful 4WD tractors.
Frame Front Gangs Walking Beam Axles Hydraulic Lift System
The 4600 features heavy-duty frame construction. Both main and wing frames are all-welded, entirely of 8” x 4” x .375 wall tubing. To carry the massive outer gangs, each outrigger on the wing frames is additionally strengthened over the wheels to an unbelievable 12 inches.
Staggered, overlapping front gangs on the Model 4600 disc ensures that all soil at the center of the disc is cut out cleanly and evenly. Besides leaving a more level soil profile, this feature eliminates the need for a center shank or bulk buster normally supplied on most conventional tandems.
Tandem Walking beam axles are standard on the 4600 main frame when equipped with 12.5L tires. Each walking beam pivots on two tapered roller bearings to improve weight distribution and stability when the disc is being transported.
A rephrasing hydraulic lift system is standard equipment on the 4600 disc. Depth stop segments c/w holder (main frame lift cylinder only) 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.
Main Frame Rockshaft Hydraulic Fold Rugged Tires
A heavy-duty main frame rockshaft forms the backbone of the 4600 lift system. Constructed of 6-5/8” diameter heavy wall tubing, the rockshaft rotates freely in three greaseable graphite-plastic bearing saddles designed to eliminate metal to metal wear points.
All 4600’s fold hydraulically to a transport width of 17’6”. Narrow wing sizes (28’-32.5’) features two 5” x 36” wing lift cylinders; wide wing sizes (35.5’-42.5’) come equipped with four 5”x36” lift cylinders. Hydraulic lockout valves are supplied standard to prevent accidental operation of either the lift or wing cylinders when the disc is being transported.
Rugged 40 x 19 x 19.5 Off-Highway tires (6) are available as an option on the 4600. Severe ground conditions, repeated and prolonged road travel or additional floatation are only a few reasons to consider this option.
