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.
ATTENTION! RISK OF ACCIDENT
The cutting depth is adjusted by the following points:
1. Disc gangs opening
- Increase the opening (A) between the gangs to work over soils that are harder to
penetrate with the disc blades. In light and loose soils, it is appropriate to work with a
smaller opening angle.
- To open or close the disk harrow, activate the course limiter lock and move the
equipment forward or backward to the desired spot.
- To open or close the equipment, the operator must activate the hydraulic cylinder
control valve.
- Note that the disk harrow opening just change the cutting angle of the rear gang.
Increasing "A": bigger disc blades penetration.
Decreasing "A": smaller disc blades penetration.
