Decreasing Net Wrap Brake Bar Tension

In certain conditions, friction between net wrap material and stainless steel supports may be too high, causing one or more of the following symptoms:

  • Breaks in net wrap material causing ruptures from bulges of crop material.
  • Net wrap roll will not rotate and feed onto bale.
  • Net wrap material is tight on some areas of the bale and loose on other areas.
  • Net wrap material is split around the bale.
  • Plastic, powder-like residue is present on stainless steel supports.

If any of the above conditions occur:

1. Make sure the approved net wrap material is being used.

2. Decrease tension on brake bar.

IMPORTANT: Be careful not to bump rod of gas spring. Any damage can greatly reduce life of spring.

NOTE: Support net wrap cover while removing and installing gas spring.

Decrease tension on brake bar by moving gas springs (A) to alternate hole positions using the following table.

To relocate gas springs:

This procedure will prevent binding and make repositioning of springs easier. 1. Remove gas spring from one side.
2. Reposition other gas spring to desired position.
3. Reposition first gas spring.
