Inaccurate or inconsistent cut lengths ?
The answer could be with your Puller.
If you are experiencing in-line cut length issues with either a Rotary Cutter or Profile Saw then there are a few areas to look into in order to resolve the issue.
The issue may not be the Cutter or Saw itself but could stem from the Caterpillar Take-Off.
Check the Take-Off is running consistently. If not this will cause inaccuracy in cut length.
Check the encoder.
Is the product slipping in the Take-Off - do the belts need replacing or changing for more product specific belts ?
Are the Caterpillar Belts too close to each other ?
Check the drive shaft on the Take-Off
