IMPORTANT: The machine must be ready to start planting, filled up with seeds.

  1. Connect hoses to tractor's SCV.

    NOTE: See Coupling and Uncoupling.

  2. Keep valves (A and B) initially closed to avoid exceeding turbine maximum operating speed.

  3. Start up engine and set tractor to working speed (the speed used for planting).

  4. Engage CCS system agitator via key (A) on corner post.

  5. Check if the tractor selective control valves are in constant flow position (B) and maximum flow. Shift to this position if not.

CAUTION: DO NOT surpass the pressure of 30 inches of water for the CCS tank. Any pressure greater than this may damage the hydraulic motor.

IMPORTANT: Lower planter completely to carry out CCS pressure adjustment, keeping constant flow at SCV.

NOTE: Check the CCS pressure value indicated for each crop in Tank Pressure Table.

  1. Make sure knob (C) is closed.

  2. Totally open valve (A) or (B) (depending on the valve to which the vacuum hose is connected).

  3. Turn knob (C) until the recommended CCS pressure level is achieved, paying close attention to the position of the needle on the gauge.

  1. NOTE: Check the vacuum value indicated for each crop type in Seed Rate - Vacuum Meter Section.

    Check that there are seeds in seed metering boxes.

  2. Open knobs (C) completely.

    CAUTION: DO NOT operate the planter with one or both valves totally closed.

  3. Turn adjustment handle (A) or (B) (depending on the valve to which the vacuum hose is connected) until the required vacuum level is achieved, paying close attention to the position of the needle on the gauge.

  4. Plant a small number of seeds or rotate the disks so that they become filled with seeds.

  5. If the difference in the vacuum between one planter and the other is above 2 vacuum inches, then carry out fine adjustment through valves (C).

    Turn knob (C) referring to planter that has higher vacuum level, restricting its flow until the two planters are even.

  6. After these initial adjustments are made start to plant and pay careful attention to gauge readings, carry out fine adjustment on tractor VCS if necessary.
