The 4500 features heavy-duty frame construction. Both main and wing frames are all-welded, entirely of 6” 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 10 inches.
Staggered, overlapping front gangs on the Model 4500 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.
All 4500's fold hydraulically to a narrow transport width of only 12’ (3m) which provides a safer transportation from point A to point B. Two 5” x 36” cylinders fold or unfold the two wings. Hydraulic lockout valves are supplied standard to prevent accidental operation of either the lift or wing cylinders when the disc is being transported.
A rephrasing hydraulic lift system is standard equipment on the 4500 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.
 
Tandem Walking beam axles and 11L x 15 L/R "F" tires are standard on the 4500 mainframe. Each walking beam pivots on two tapered roller bearings to improve weight distribution and stability when the disc is being transported.
A heavy-duty main frame rockshaft forms the backbone of the 4500 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.
