Cleaning Out Seed Hoppers and Vacuum Metering Units

causym CAUTION: Avoid crushing injury. Frame control box PLANT-TRANS switch must be in TRANS position, service locks must be installed, and the following procedure must be followed as outlined.

Avoid crushing injury. When procedure is complete, place tractor selective control valve (SCV) in Neutral position before PLANT-TRANS switch is moved to PLANT position.

The Purge-Plant switch (C) allows the fan to operate while machine is in a raised position. Operator is able 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.

causym CAUTION: Avoid crushing injury. If the rockshaft row units are raised, rockshaft cylinder locks must be installed. The rockshafts lower when SCV lever is moved to lower position.
