Side-to-Side Frame Leveling

All frame sections must be level to maintain even seeding

depth. Before using the implement in the ﬁeld, follow these

steps to make sure the implement is level side-to-side.

Periodic frame-leveling adjustments should not be neces-

sary, but if you are having problems with uneven depth,

check drill levelness and follow these procedures.

NOTE: For front-to-back leveling, see Setting the Seeding

Depth, “Adjustments,” page 20.

45-Foot Drill

Since the dual gauge wheels on frame sections three and

four are not adjustable, make all adjustments with these as a

reference.

WARNING!

You may be severely injured or killed by being crushed by a fall-

ing implement. Always have the frame sufﬁciently blocked up

when working on implement.

1. Check that the lift circuit is free of air and full of oil. Re-

fer to Bleeding the Hydraulics, page 12.

2. Hydraulically lower the entire implement frame. Fully

retract all gauge-wheel cylinders. Block up or otherwise

safely support the implement frame.

3. Take a reference measurement off one dual gauge-

wheel as shown in Figure 1-7. Lay a straight edge

across at least two tubes of frame section three or

four. Extend the straight edge out over the axle. Mea-

sure the distance from the bottom of the straight edge

to the center of the dual gauge-wheel axle.

4. Move the straight edge out to the ﬁrst frame section.

Lay the straight edge across at least two frame tubes.

Extend the straight edge over the non-castored,

gauge-wheel axle. Measure the distance from the bot-

tom of the straight edge to the center of the axle. If the

dimension is the same as the reference measure-

ment, no adjustment is necessary. Proceed to step 7.

5. If the wing measurement differs from the reference

measurement, unpin the gauge-wheel arm. Position

and support the arm to a height that matches the ref-

erence measurement.

6. Swing the cylinder down and adjust the eye-bolt until

the pin holes line up. Secure the eye bolt with the jam

nut and repin the cylinder to the gauge-wheel arm.

See Figure 1-8.

7. Move the straight edge so it lies over the castored

gauge-wheel axle. Adjust the eye bolt at the base of

the cylinder (see Figure 1-9) until the center of the axle

is about 1/2-inch higher than the reference measure-

ment. Secure eye-bolt by tightening the jam nuts.
