Adjustments and operations
Operations - important points
• To carry out any verification on the equipment, lower it to the ground and shut
down the tractor engine.
• Whenever unhitching the equipment, either in the field or shed, do it on a flat
and firm place and use the jacks. Make sure that the equipment is properly
supported.
• Carry out the operations with a controlled and careful manner.
• As stated before, the maneuvers must always be done to the left hand side.
• The harrow activation to open or close the gangs must be done gradually, being
the tractor in movement.
• Relieve the control valve pressure before disconnecting the quick couplers and
when doing any verification in the hydraulic circuit or on the retention valve.
• Do not check eventual leaks using your bare hands, as the high pressure may
cause body injury. Use a cardboard or any other suitable object instead.
• As previously mentioned, this disk harrow has several settings. However, only
the local conditions can determine its best adjustment.
