Disk harrow maintenance
• During offseason, wash the equipment, repair any damaged paintwork, protect the
disc blades with oil, lubricate all grease fittings and store the disk harrow in a covered and
dry place, avoiding the direct contact of the disc blades with the soil.
• The disc blades must be replaced as soon as they are providing a low yield, mainly
because of the reduction in its diameter, loss of cut and other damages that may occur
during the job.
• After 24 working hours, the bolts on the disk harrow must be checked to see if they
are properly tightened. To assure a great performance and avoid wear and rupture, these
bolts must be tightened every so often.
• Check wear occurence on all moving parts. Replace any part, if necessary.
• Replace the missing or damaged safety decals. Marchesan supplies these decals
upon request and indication of their respective serial numbers. The operator must know
the need and importance to keep the decals in the proper place and in good conditions.
The operator also have to know the need to follow the instructions, as the lack of safety
may increase the risk of accidents.
Maintenance
IMPORTANT When uncoupling the equipment from the tractor, lift it and place the
locks (A) on the cylinders; after that, lower the disk harrow until it
touches the locks and place the jack with pin and cotter pin.
If it is necessary to totally lower the equipment, do not place locks and
neither the pin on the jack, as such procedure may result in damages
to the jack itself.
