Heavy-Duty Down Force Springs

The heavy duty adjustable down force spring system is recommended when planting in rough field conditions and when the soil or soil residue is difficult to penetrate. The spring system will transfer main frame weight to the planting unit to minimize bounce and to assist the opener to penetrate heavy soil conditions. The amount of force transfer is adjustable from 0 to 1779 N (0 to 400 lbs.) of down force. Never use more down force than is necessary to prevent excessive drive wheel slip.

To adjust the down force springs, proceed as follows:

Raise the planter.

Lift up the spring adjusting handle (A).

Place the spring adjusting handle in front slot (as shown) for MINIMUM down force.

Place the spring adjusting handle in the rear slot (B) for MAXIMUM down force.
