Maintenance
Precision Planting - seed metering maintenance
1) Check for wear occurence on the singulator.
• Replace when there is excessive wear. An increase on doubles may indicate excessive
wear on this piece.
• It is possible to check the singulator using the tool from the eSet kit.
2) Check if there is any crack/wear on the vacuum sealing.
3) Check if the graphite from the seed plate was removed. (Re-apply graphite if
necessary).
• Replace the seed plate if the holes become deformed or if the seeds are going to the
vacuum side.
4) Check for any wear on the ejector wheel.
• Replace the set if there is any excessive wear on the arm inside the ejector wheel.
• Inspect each pin of the ejector wheel to see if they are intact.
• Check the plastic tension and replace it if it is loose on the assembly place.
5)
Check for excessive wear on the brushes.
• If there is excessive clearance/wear that allows the seeds to pass through the brushes,
replace them.
6) Test the meterings on the MeterMax Ultra test bench to assure a greater performance.
7) When in off-season, disassemble the meterings.
• Remove the crop components of the kit from the metering carcass.
• Store in a dry and flat place.
8) vSet2 vacuum sealing replacement
• Remove the sealing by pulling it out of the metering carcass.
• Check if both the new sealing and the slot on the metering carcass are free from
debris. If they need to be cleaned, use hot water and a cloth or compressed air.
• Insert a new sealing on one of the ends of the carcass. As the sealing gets adjusted,
check if the retention tongues on the surface of the metering are showing up. Be sure that
the sealing is well fitted and that there are no protrusions.
• Every retention tongue must be used and the sealing must fit on the cavity. The
tongues alignment will help to assure the proper sealing.
• When using a pressure washer, do not direct the jet to the electronic modules (SRM,
Power Module, PDM, Smart Connector, RUM, vDrive and so on), seed meterings and
connection harness.
• When disconnecting any connection between crops for disassembling or maintenance
purposes, the exposed connectors must be protected from the environment.
