Adjustments and operations
Operations - Important points
• Tighten nuts and bolts after the first day of service and check the conditions of
all pins and cotter. Then, retighten every 24 operating hours.
• Special attention should be given to the disc gangs, retightening daily during
the first week of use. Then, retighten periodically.
• Carefully remember the lubrication intervals (see lubrication instructions on
page 23).
• Choose a gear that allows the tractor to maintain certain power reserve, ensuring
against unforeseen efforts.
• The work speed is relative to the tractor gear and can only be determined by
local conditions. We adopted an average
7 to 12 Km/h
, which is not advisable
to overcome to maintain service efficiency and avoid possible damage to the
equipment.
• The harrowed ground should always stay on the left hand side of the operator.
• Use a tractor with enough power to operate the harrow.
• During work, do not perform maneuvers to the right hand side, because the angle
formed by the disc gangs will transmit great effort to the equipment, especially
to the traction components.
• Remove pieces of wood or any object that may attach in the disc blades.
• During work or transportation, the presence of passengers on the tractor or
equipment is not allowed.
• The traction bar must remain loose during transportation and fixed during
working
.
• As previously mentioned the GLHAL harrow has several settings. However, only
the local conditions can determine the best adjustment thereof.
