Setting Selective Control Valves-8000 Series Tractors

NOTE: If tractor is not equipped with enough SCV outlets, a Power Beyond Kit is available to operate hydraulic motors.

NOTE: Vacuum flow control valves supplied with the machine should remain in the hydraulic circuit for each motor and be adjusted to the full open position to act as a flow limiter when SCV is controlling vacuum.

Press appropriate touch control switch (A) I through V to set up each SCV.

MACHINE RAISE AND LOWER: Press touch control switch I to adjust raise and lower function. Use flow control knob (B) to adjust flow rate. Use knob (C) to set time detent at 5 seconds. Adjust in the field as required.

INDEPENDENT MARKERS (if equipped): Press appropriate touch control switch to adjust marker raise and lower function. Use flow control knob (B) to adjust flow rate. Start flow rate setting at seven and adjust as necessary. Use knob (C) to set time-detent knob (C) to 10 seconds and adjust in field for proper time to extend and retract.

VARIABLE RATE DRIVE (if equipped): Press appropriate touch control switch to adjust hydraulic variable rate motor function. Use flow control knob (B) to set flow level to 10. Use knob (C) to set detent time to CONSTANT. Push tractor SCV lever into detent and release to operate variable rate motor. Place SCV in FLOAT to turn off variable rate motor.

VACUUM MOTOR (if equipped): Press appropriate touch control switch to adjust hydraulic vacuum motor function. Use flow control knob (B) to set desired vacuum level (the flow control valve on the machine must be set to full open). Start with a low flow setting of 2.0 on display and adjust for correct vacuum level after seeds are on the disks. Use knob (C) to set detent time to CONSTANT. Push tractor SCV lever into detent and release to operate vacuum motor. Place SCV in FLOAT to turn off vacuum motor.
