Maintenance
• When the existence of looseness is noticed, it is necessary to make the maintenance
in the hubs of the disc blades, unaligned double discs, gauge wheels and press wheels.
• Disassemble the hubs and remove the internal components.
• Clean all parts with diesel oil and kerosene.
• Verify the existence of looseness and the conditions of
the bearings, retainers and bushings. Replace the damaged
components or with excessive torque.
• The hubs without grease fittings should be reassembled
with a good amount of lubricant.
• The hubs with grease fittings should be lubricated until the
new grease is visible.
• The hubs with tapered roller bearings fastened by castle
nut and cotter pin allow the adjustment of the inner clearance;
excessive tightening should be avoided. The hubs should rotate
with the hand applying a small effort.
It is necessary to make a general
cleaning in each seed metering daily. To do
this, remove the seed plate and observe the
metering mechanism operation. By doing
so, the best planting will be assured.
When using graphite powder
with treated/inoculated seeds,
it is necessary to clean the
system twice a day.
