A - Purge/Plant Switch

The Purge/plant switch (A) 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 and install lift assist wheel cylinder service locks.

  2. Place tractor in park.

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

    Place CCS fan hydraulic SCV lever into retract-detent position.

  4. Ensure that Purge/Plant switch is in PLANT/TANK CLEANOUT position.

  5. 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 manufactures 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.

    IMPORTANT: Make sure cleanout doors on CCS tanks are closed before folding machine or they can be damaged.

    If tanks contain large amounts of seed, use slide door (A) to reduce seed to a manageable level. Once cleanout doors (B) are open they cannot be closed completely until seed stops flowing. Repeat on each tank.


  6. NOTE: Purge/Plant switch must be in TANK/CLEANOUT position or CCS fan forcefully expels seed from cleanout doors.

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

  7. Close cleanout door.

  8. Repeat on remaining cleanout doors.
