Leveling The Outside Booms - MacDon 625 Operator's Manual

Leveling the Outside Booms

If the outside boom is not level to the ground, do
the following procedure:
1. Park the self-propelled windrower in a flat, level
area with the booms in the FIELD position.
2. With a tape measure, measure the height of
the boom off the ground nearest the main
frame of the sprayer attachment.
3. Measure the height of the boom near the boom
tip breakaway linkage. If the height is different
and leveling is required, raise the boom to the
maximum height. Lower the boom props and
ensure they are secured.
4. Lower the boom on to the boom prop until the
vertical suspension linkage is slack. Using a
ladder, adjust the length of the linkage by
turning the nut on the eyebolt to get the correct
boom height.
NOTE: Keep the booms in a horizontal or
slightly tipped up position to maintain correct
ground to boom height clearance.
Repeat the procedure for both booms until the
necessary height adjustment is correct.
