Operations - Important points
Adjustments and operations
• Retighten nuts and bolts after the first day of work and check the conditions of
all pins and cotter pins. Then, retighten every 24 operating hours.
• Carefully observe the lubrication intervals.
• Special attention should be given to the disc gangs, retightening daily during the
first week of use. Then, retighten periodically.
• Choose a gear that allows the tractor to maintain certain power reserve, ensuring
against unforeseen efforts.
• Always inflate the tires with the aid of a contention device (tire inflation cage).
• The correct tire inflation is important; keep the same pressure on every tire.
(Check the 'tires inflation' page on the 'maintenance' section).
• Speed is relative to the tractor gear and can only be determined by local conditions.
We adopted an average 05 to 07 km/h, which is not advisable to overcome to
maintain service efficiency and avoid possible damages to the equipment.
• It is important to keep a constant speed during the whole operation.
• Only people who own a complete knowledge of the tractor and equipment must
operate them.
• Be on a wide field and maneuver on slow gear to hitch the equipment, being
ready to brake when necessary.
• Remove sticks or any object that may get stuck on the disc blades.
• The tractor drawbar must remain loose during working and transportation.
• Only pull the equipment using a tractor with enough power.
• During working or transportation, do not allow passengers on the tractor or
equipment.
• Always keep the equipment centralized related to the tractor and leveled related
to the soil.
• To carry out any verification on the equipment, lower it to the ground and shut
down the tractor engine.
• Whenever unhitching the equipment, either on the field or shed, do it on a flat
and firm place and use the parking jacks.
• Carry out the operations on a controlled and careful manner.
• Before maneuvering, gradually activate the hydraulic cylinders to lift the disc
gangs.
• During working, do not maneuver without totally lifting the disk harrow, as
the angle formed by the disc gangs would start to transmit great effort to the
equipment, thus overloading the traction components.
• 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.
• As previously mentioned, this disk harrow has several settings. However, only
the local conditions can determine its best adjustment.
