Setting Selective Control Valves-8000 and 9000 Series Tractors

NOTE: If tractor is not equipped with enough SCV outlets, a Power Beyond Kit is available to power hydraulic motors. An in-line flow control valve kit must also be installed to control vacuum level. See your John Deere dealer.

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

MACHINE FRAME FUNCTIONS: Press touch control switch I to adjust raise, lower, markers (if plumbed automatic), fold functions and CCS fan. Use flow control knob (B) to adjust flow rate. Use knob (C) to set time detent to CONSTANT. Reduce flow rate when folding and unfolding.

INDEPENDENT MARKERS (if equipped): Press touch control switch II to adjust. Set flow rate to 5 with knob (B) and time detent to 10 seconds with knob (C). Adjust in the field as required.

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 OPTIONS:

1. DUAL VACUUM MOTORS CONNECTED TO SEPARATE SCV'S: Press appropriate touch control switch to adjust hydraulic vacuum motor function. Use flow control knob (B) to set desired vacuum level. Start with a low flow setting of 2.0 on display and adjust for correct vacuum level after seeds are on vacuum disks. Use inline flow control valves to set desired vacuum levels. Start with a low flow setting 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 motors.

2. DUAL VACUUM MOTORS CONNECTED TO SINGLE SCV: Press appropriate touch control switch to adjust hydraulic vacuum motor function. Set flow control knob (B) to 10. Use inline flow control valves to set desired vacuum level. Use knob (C) to set detent time to CONSTANT. Push tractor SCV lever into detent and release to operate vacuum motors. Place SCV in FLOAT to turn off vacuum motors.
