Preparing to Operate in Field-John Deere 7000 Series Tractors

NOTE: Machine weight, gang angle, blade type, blade sharpness, and operating speed all affect how deep a machine will operate in a particular soil condition. Operate machine over a short test distance (approximately 45 M [50 yards]) and adjust as necessary to obtain maximum working depth and best level results.

1. Rigid Machines -Remove depth control cylinder lock-up from cylinder and store it in field position.

Folding Machines -Open hydraulic cylinder transport lock-up valve.

Follow safe procedures in Attaching and Detaching section.

causym CAUTION: 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.

2. If equipped with Hydraulic Wing Control Option, open wing fold lock-up valve.

3. See that area is clear, then push SCV II forward to unfold wings (if equipped) and extend wing cylinder(s) fully. Place SCV II (B) in FLOAT position when wings are fully unfolded on ground. (See your tractor's Operator's Manual for placing SCV levers in FLOAT.)

4. Use SCV I (A) to raise and lower machine several times.

IMPORTANT: To prevent damage to wing fold cylinder, if your machine is equipped with Hydraulic Wing Control Option, do NOT attempt to operate during initial field setting. Set operating depth and leveling with SCV lever in FLOAT position. For machines equipped with Hydraulic Wing Control Option (See HYDRAULIC WING CONTROL OPERATION in this section.)

5. Folding Machines -hold lever rearward for a few seconds after machine has fully raised to rephase or synchronize depth control cylinders.

6. Operate machine over a short test distance at 6.4-9.7 km/h (4-6 mph). Use SCV I lever (A) to raise lift wheels and lower machine until desired disking depth is achieved. Stop tractor and lower gauge wheels until they exert pressure on ground.

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.

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

7. With depth set, operate over a short test distance at 6.4-9.7 km/h (4-6 mph). Stop tractor and set field profile at center of machine. Turn leveling crank clockwise to eliminate center valley or counterclockwise to eliminate center ridge, or adjust front-to-rear leveling using hydraulic motor if equipped. (See ADJUSTING FRONT-TO-REAR LEVELING IN FIELD -CRANK ADJUSTED or ADJUSTING FRONT-TO-REAR LEVELING IN FIELD WITH HYDRAULIC LEVELING MOTOR in this section.)

8. With another person observing machine from rear, operate over a short distance at 6.4-9.7 km/h (4-6 mph) to see if wing frames are level to main frame. Adjust, as necessary, eyebolt on each wing depth lift cylinder until gang tubes are level side-to-side across width of machine. (See ADJUSTING SIDE-TO-SIDE LEVELING in this section.)

9. Confirm depth setting:

Single Point Depth Control -Pull SCV I lever to raise machine; and then push forward to lower machine and confirm depth settings.
