CAUTION: Hydraulic hoses can fail due to physical damage, kinks, age, and exposure. Check hoses regularly. Replace damaged hoses.

IMPORTANT: Vacuum and Variable Rate Drive RETURN hoses, with special tip, MUST be connected to tractor EXTEND port. Avoid damaging pressure spikes; shut vacuum motor and variable rate drive off by placing SCV lever in “Float” position.

CCS control valve is used to control CCS tank pressure.

SeedStar™ system is used to control variable rate drive.
