    Transport Lockup Valve Open

    Failure to close transport lockup valve could cause machine to unfold unexpectedly during transport causing serious injury or death to you or others.

    Machine weight, gang angle, blade type, blade sharpness, and operating speed all affect how deep a machine operates in a particular soil condition. Operate machine over a short test distance (approximately 46 m [50 yards]) and adjust as necessary to obtain maximum working depth and best level results.

    Attach machine to tractor. (See Attaching and Detaching section in this manual.)


  2. Open transport lockup valve (A).

    A - SCV II Multi-Function Lever

    B - SCV I Multi-Function Lever

    Wings are heavy and can fall causing serious injury or death to you or others. Stay clear of machine when folding or unfolding wings. Never raise or lower wings when moving.

    Machine must be fully raised before folding or unfolding.

    Verify that area is clear, then push SCV II multi-function lever (A) forward to unfold wings and extend wing cylinders fully. Place SCV II multi-function lever in FLOAT position when wings are fully unfolded on ground. (See your tractor Owner's Manual for placing SCV multi-function lever in FLOAT.)


  4. Never operate SCV I in CONTINUOUS. Wheel retraction valve can cause machine to unfold unexpectedly causing serious injury or death to you or others.

    Raise and lower machine several times using SCV I multi-function lever (B).

  5. Hold lever rearward for a few seconds after machine has fully raised to rephase or synchronize wing depth control cylinders.

    A - SCV I Multi-Function Lever

    Operate machine over a short test distance between 6.4—11.3 km/h (4—7 mph) for disk machines and between 11.3—16.1 km/h (7—10 mph) for vertical tillage machines. Use SCV I multi-function lever (A) to raise lift wheels and lower machine until desired operating depth is achieved.

    Gauge wheels must support frame for level disking results.

    Pulling depth gauge wheels completely off ground does NOT help achieve maximum disking depth and causes unlevel disking results.

    Use Single Point Depth Control to set operating depth.

    Place transmission in PARK, set brakes, and turn tractor off. Set single point depth control using crank at front of machine. (See USE SINGLE POINT DEPTH CONTROL in this section.)


  7. With depth set, operate over a short distance between 6.4—11.3 km/h (4—7 mph) for disk machines and between 11.3—16.1 km/h (7—10 mph) for vertical tillage machines. Stop tractor and check field profile at center of machine. Eliminate center valley or center ridge by adjusting front-to-rear leveling using tractor SCV III. (See LEVEL MACHINE FRONT-TO-REAR IN FIELD in Operating Machine section.)

  8. With another person observing machine from rear, operate over a short test distance between 6.4—11.3 km/h (4—7 mph) for disk machines and between 11.3—16.1 km/h (7—10 mph) for vertical tillage machines to see if wing frames are level to main frame. Adjust as necessary, eye bolt on each wing depth lift cylinder until gang tubes are level side-to-side across width of machine. (See LEVEL WINGS TO MAIN FRAME IN FIELD in this section.)

  9. Confirm depth settings:

    Pull SCV I multi-function lever rearward to raise machine. Then, push forward to lower machine and confirm depth setting.
