Troubleshooting

Most common issues concerning round bale net wrap

We closely follow the development of balers. The starting point of our own product development is to ensure brand and model compatibility. In practice, this is done in close cooperation with our customers in the field while baling.

The net wrap is not spreading properly, misshapen bales

Inadequate netwrap tension during wrapping

  • Adjust brake bars and feeding rollers, if necessary reduce distance between feeding rollers using our adjustment strip.
  • Check spreading bar for smooth running and cleanness, clean spreading bar.

The core is slipping on the shaft

  • In case of balers with axle mounting: core is slipping on the axle fastening. Ensure proper roller core attachment.
  • In case of balers with axle mounting: ensure that roller base is properly attached.

Net pulls to either side of the bale

  • Make sure to feed net wrap evenly into the bale chamber.
  • Remove feed residue from the rollers of the net guide trays.
  • Make sure the net is introduced into the chamber in a straight line. If it is not positioned in the centre, adjust rolls in relation to chamber.
  • Check feed rollers for even pressure on right respectively left side (using adjustment strip).

Unevenly formed and/or excessive pressure in the bales

  • Pay attention to the bale chamber filling. Drive slower especially in the final stage of baling.

Hourglass-shaped bales, less tension in the middle of the bale prevents net from spreading to the edges of the bale

  • Change your driving behaviour, try to get more material into the central part of the chamber.

correct driving technique

Unevenly formed, round bales

  • By employing the correct driving technique, you can ensure that the bales will get shaped evenly. Avoid zigzagging and sloping as this will produce round bales.

    The best result is achieved by driving about 30 metres straight down one edge of the windrow, followed by a steep turn in the direction of the opposite edge. After that, drive straight for another 30 metres.
The net cannot be cut properly

Dull or rusty knives

  • Sharpen or renew the knives.

Insufficient net tension during the cut

  • Adjust brake and/or feeding rollers (use adjustment strip).
Net gets tangled around rolls

Net hasn't been properly cut, strings hang from the net

  • Sharpen or renew the knives.
  • Adjust brake to ensure sufficient net tension during the cut.

Insufficient net tension during the cut

  • Adjust brake and/or feeding rollers (use adjustment strip).
Ladders on the bales, split bales

Loose threads hanging out off the bale due to improper cut of the net

  • Ensure that net is sufficiently tense during the cut. Adjust brakes if necessary. The net must be pulled tight at the point of cutting.
  • Sharpen or remove cutting blades.

Insufficient net tension during the cut / core is slipping on the shaft

  • In case of shaft fastening models, ensure that roller core is properly attached.
  • Adjust brake bars or feeding rollers.

Feed of net wrap is skewed due to misalignment of feeding rollers

  • In case of shaft fastening models, ensure roller core attachment.

Net gets damaged by feeding rollers

  • Clean feeding rollers, release net retention in time.

Chamber rollers damage the net

  • Sharpen or replace the knife.
  • Adjust net brake.
  • Ensure the rollers are clean and undamaged.
Split bales

Chamber rollers have damaged the net

  • Adjust pto RPM's properly while ejecting bale.

Chemical products such as pesticides have come in touch with the net wrap

  • Minerals and chemicals such as sulphate, chlorine, copper, aluminium and other herbicides may strongly damage the net's UV stability. The same goes for environmental factors like exhaust fumes, acidic rain and residue from various fuels.

Bale damage occurs when bale is ejected

  • Check, whether the tailgate is lowered to soon or does not open wide enough.
  • Check and make sure the baler is in the correct horizontal angle with respect to the tractor.
  • Check the power take-off RPM's when ejecting the bale. RPM should be adjusted according to the baler manual.

Not enough layers

  • Use at least 2.2 complete layers, 3.3 layers are perfect.
  • Check actual amount after having wrapped 2 - 3 bales.
  • Use more layers for more challanging forages such as corn stalks and straw.
Net wrap ripps during baling

Net break is released prematurely

  • Lock cutting knife properly.
Netwrap hangs loosely on the bale

Net tension is not sufficiently adjusted, either too low or too high (rubber band effect)

  • Adjust net tension properly.
