Using SCV Control Levers

causym CAUTION: To avoid personal injury, ensure hoses are not reversed. If cylinder response is reversed (extending instead of retracting), reverse hose connections at couplers.

NOTE: Float can also be used to allow hydraulic motors to coast when shutting down an implement.

SCV control levers have six positions:

  • Neutral (F) -Lever returns to center position when released except in float position
  • Extend (G) (rearward between Neutral and Extend Detent Position)-Variable flow to extend cylinder, proportional to lever movement and flow settings; shuts off when released to center position
  • Extend Detent Position (I) (rearward to "click" position)-Timed flow to extend cylinder, based on detent time setting and at a rate set by flow rate control. See Adjusting Detent Time and Adjusting SCV Flow Rate in this section. Lever returns to neutral when released
  • Retract (H) (forward between Neutral and Retract Detent Position)-Variable flow to retract cylinder, proportional to lever movement; shuts off when released to center position
  • Retract Detent Position (J) (forward to "click" position)-Timed flow to retract cylinder, based on detent time setting and at a rate set by flow rate control. See Adjusting Detent Time and Adjusting SCV Flow Rate in this section. Lever returns to neutral when released
  • Float (K) (fully forward and down into locked position)-Valve is open to sump to allow cylinder to extend or retract to allow implement to follow ground contour; must be pulled up and out of locked position to disengage

NOTE: To relieve hydraulic pressure in implement, move SCV control lever to float position, while engine is running.

Push SCV lever covers (E) forward when SCV is not in use.
