Maintenance
Cleaning the seed metering
Maintenance of the row hubs
NOTE
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.
• When the existence of looseness is
noticed, it is necessary to make the maintenance
in the hubs of the coulter 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 bearings, retainers and bushings.
Replace the damaged components or with
excessive wearing.
• 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.
