cracking hydraulic fittings from over tightening, do
not use plastic sealant tape.
Frame Leveling Adjustment
Periodicframeleveling should notbenecessary,but if you
are having trouble maintaining equal coulter depth across
the drill, check that the frame is level. When the drill is level, the box frames will be the same distance from the
ground at both ends of the drill.
Completethestepsunder BleedtheFoldHydraulics,page
12, before proceeding.
Refer to Figure 1-4.
1. Locate the threaded eye bolt at the base end of the
gauge-wheel cylinders (1). The eye bolt is locked in
place bya jam nuts. Observe the amountof thread exposed abovethe upper nut andbelow the lower nut. If
the exposed threads are roughly equal, no initial adjustment is needed. Go to step 3.
2. If the exposed threads above and below the nuts are
not equal, loosen and adjust the jam nuts until the exposed threads are within 3/8 inch of each other.Repeat for other end of drill.

3. Move the drill to a level area. With the drill unfolded,
check that the tool-bar cylinders are completely extended. Raise the drill to its highest position with the
field-lift cylinders. With the tractor idling, rephase the
cylinders by holding the hydraulic lever on for an additional 30 seconds. Immediately lower the boxes until
the coulters and openers are just ready to touch the
ground.
4. Move the gauge-wheel eye bolts (1) in or out until the
framesare level.Whentheframesare level,theopeners on the outside end of the drill will be the same
height as the center openers.
NOTE: Eye-bolt adjustments are easier if the drill is first
lowered to the ground to remove some of the force on the
cylinders.
5. Repeat the steps above until the drill is level end-toend when drilling in actual seeding conditions.
