7. Adjustments and operations
Cutting depth
• Only CAPABLE and AUTHORIZED personnel must carry out the adjustments and
operations of the equipment.
• Observe every safety condition and use safety glasses, foot protection, earplugs/
muffs, protective gloves and any other required PPE.
• Do not carry out any adjustment while the equipment is working.
DANGER
• To start the harrowing, we recommend using an average opening in the disc gangs.
If a greater penetration is needed, increase the rear gang opening angle.
• The front gang usually does not operate with a greater opening than the rear gang.
• Try to make a good finish between passes. Avoid the formation of furrows or
untilled strips.
WARNING
The cutting depth is adjusted through the disc gang opening:
1. Increase the opening angle between the disc gangs to work over soils that are
harder to penetrate. In light and loose soils, work with a smaller opening angle.
2. This adjustment can be done by changing the fixation of the disc carrier on the
main frames.
