Heavy-Duty Downforce Springs

The adjustable heavy-duty downforce spring system is recommended when planting in rough field conditions and when soil or soil residue is difficult to penetrate. Spring system will transfer main frame weight to planting unit, to minimize bounce and to assist opener in penetrating hard soil conditions. The amount of force transfer is adjustable from 0 to 181 kg (0 to 400 lb). Never use more downforce than necessary to prevent excessive drive wheel slip. In tough conditions, ballast weight may be required.

To adjust downforce springs, proceed as follows:

2. Lift spring-adjusting handle (A) and place into notch (B), (C), (D) or (E) for desired amount of downforce.

• Use notch (B) for Zero kg (lb) of downforce.
• Use notch (C) for 57 kg (125 lb) of downforce.
• Use notch (D) for 113 kg (250 lb) of downforce.
• Use notch (E) for 181 kg (400 lb) of downforce.
