A - PLANT-TRANS Switch

B - Center Frame Service Lock

C - CCS Fan Switch

The CCS fan switch (C) allows the fan to operate while machine is in a raised position. This enables the operator to clean out the CCS tanks and purge the hoses without climbing in and out of the tractor cab. The following procedure must be completed in the order given to avoid possible injury and machine damage.

  1. Raise machine.

  2. Place tractor in park and apply parking brake.

  3. Install wing and centerframe service locks (B).

  4. Position (frame control box) PLANT-TRANS switch (A) in TRANS position.

  5. NOTE: With PLANT-TRANS switch in TRANS position, frame cannot lower.

    NOTE: With frame in raised position, the CCS row unit switch disables CCS fan.

    Place SCV lever into frame lower-detent position.

  6. Purge-Plant switch should already be in PLANT-TANK CLEANOUT position and should remain in that position for tank cleanout.

  7. CAUTION: Use caution if using seed treatments when opening meter doors. Chemical can cause eye, skin, or breathing problems. Wear mask, gloves, and goggles. Read and follow safety instructions on the chemical supplier’s label.

    IMPORTANT: When cleaning tank for certified seed, remove all seed from tank with stiff bristled 1372 mm (4.5 ft.) handle 203 mm (8 in.) wide broom.

    IMPORTANT: Remove any buildup of seed treatment or talc with stiff bristled 1372 mm (4.5 ft.) handle 203 mm (8 in.) wide broom.

  8. NOTE: Purge-Plant switch must be in TANK-CLEANOUT position or CCS fan will forcefully expel seed from cleanout doors.

    Place a bucket (C) or other container under cleanout door (B) and open door to clean out remaining seed.

  9. Close cleanout door.

  10. Repeat on remaining cleanout doors.
