The Model 4300 Discs are available in a range of sizes from 17ft. to 25ft. with an average weight per foot of 525lbs. Both the 4290 and 4300 models feature many of the same components including the same rugged 2-section frame, rockshafts and wheels. The main difference between the two models is in the size of their respective gang beams.
 
Heavy-Duty Frame – critical fore/aft frame beams on the 4300 is doubled over the main and wing rockshafts for additional strength. The beefy frame construction resists front to rear frame flex and eliminates the need for costly gauge wheels to prevent gouging or pushing.
Adjustable Gang Angle – the 4300 disc allows the operator to customize gang angles enabling a more or less aggressive discing action. Since most soil conditions (i.e. moisture, trash, etc.) vary from season to season an important feature such as adjustable gang angle will result in greater flexibility in the field.
Slip-in Wheel Spindles – are standard equipment on the 4300 discs making wheel or tire repair simple and easy. This feature also adds the flexibility to convert single wheels to duals should the need arise.
Hydraulic Transport Fold – all 4300 discs fold hydraulically to narrow transport width. Hydraulic lockout valves are supplied to each disc to prevent unintentional operation of either the lift of fold cylinders when the disc is being transported.
