Wing Adjustment - Bush Hog 3715 Operator's Manual

Figure 2-3 Linkage Rod Jamnut Turnbuckle
Additional mulching of cut material may be attained by
operating with the rear of the cutter slightly lower than
the front. This will keep foliage underneath cutter
longer resulting in smaller pieces of cut material. This
will increase the cutter horsepower requirements.
If you are cutting in dense material, operating cutter
with the rear slightly higher than the front will allow an
increased volume of cut material to exit from under-
neath cutter. This will decrease the cutter horsepower
requirements.
Adjust the pitch as follows:
WARNING
TO AVOID SERIOUS INJURY OR DEATH:
DO NOT PLACE HANDS, FEET OR OTHER
PARTS OF BODY UNDER CUTTER WHILE
MAKING ADJUSTMENTS. NEVER MAKE AD-
JUSTMENTS WITH CUTTER OPERATING.
IMPORTANT
NEVER ADJUST THE TURNBUCKLE SO THAT
THE THREADED END OF ANY ROD IS NOT
FULLY ENGAGED IN THE TURNBUCKLE.
A. Loosen jamnut on each linkage rod assembly.
(Figure 2-3)
B. Use the turnbuckles to lengthen or shorten the
leveling rod assemblies. Shortening the rods will raise
the front of cutter and lengthening rods will lower the
front. While adjusting, alternate from one rod to the
other.
C. When the desired pitch is attained, make a
final adjustment of the rods so that each will be
under the same amount of tension. This may be
done by tapping the rods and "tuning" them to the
same sound.
D. Re-tighten jamnut.
If cutter is allowed to rest on the ground in order to re-
lieve tension on the linkage rods, tongue must be dis-
connected from tractor to allow it to move.

NOTE

2-4 WING ADJUSTMENT

If wings are not level (parallel) from left to right with
center deck section, the cutter will windrow and pro-
duce an uneven cut. Before first use and periodically
thereafter, lower cutter to working position and check
for this condition. If adjustment is necessary, proceed
as follows:
A. Remove wing transport lock pin from locked po-
sition. Swing link out of alignment with lug on wing. Re-
place pin in link for storage during operation. Pin and
link will "ride over" wing lug. (Figure 2-4)
TO AVOID SERIOUS INJURY OR DEATH:
STAND CLEAR OF WINGS DURING AND AFTER
REMOVAL OF TRANSPORT LOCK PINS. AIR IN
HYDRAULIC COMPONENTS MAY ALLOW WINGS
TO FALL. DO NOT "DRIVE OUT" PIN IF IT IS
TIGHT AGAINST WING LUG. TO REMOVE PIN,
RETRACT WING LIFT CYLINDER TO RELIEVE
LOAD ON PIN.
Figure 2-4 Transport Lock Pin In Stored Position
B. Lower wings to ground level allowing all weight to
rest on wheels.
C. Lower cutter until skids on center section are
approximately 1" - 2" off the ground.
D. If wings are not parallel to center section,
loosen jam nut and adjust linkage shorter to lower
wing and longer to raise wing. (Figure 2-5) It may be
necessary to use wing lift cylinder to relieve pressure
from linkage retaining pin.
E. Tighten jam nut to 200 ft. lbs.
