OPERATION_
Always slow down the forward speed of the
tractor at the time of making a sharp turn,
cutting on a radius, on banks or slopes or
other uneven terrain.
REMEMBER SAFETY PAYS.
CAUTION: When mowing over rough ground
or on hillsides, the hydrostatic transmission
allows selection of safe ground speed at full
engixie ihrottlo.
PI<08I-EM
1. Cutter Iwr outer sl*oes bounces
or dtgs into grounil surface.
SOLUTION
Adjust torsion spring as indicated in
figure 1 , ( Page 4 ).
2. Inner shoe dragging on ground.
Raise inner shoe assembly by adjustment
of lift spring (Ficure 1 ). Make
sure lilt chain is properly assembled.
3. Mower does not cut cleanly
drags hay under shear knife
cutting |)actern shows blank
or skipping points.
Adjust forward travel of speed tu
coincide with sickle knife action. Check
setting of hold down clips Page 8
Check lead setting (See pa. 7)
4. Bunching of cut material in front
of inner shoe after adjustment
of lift spring.
Inner shoe is being run too close to edse
of previous swath. Allow approx. 4” overlap.
|Flg4 -Pg. 5)
5. Failure to cut grass and wced&.
Check clearance of sickle knife to shear
finger fit should he snug, 1/32" clearance.
Tap meial l>old*down plates with hammer to
adjust. Sharpen sickle knives if dull. ClK^ck
pitch of shear fingers and lead of sickle bar.
Exceptionally tall grass or weeds, uneven
terrain, may require you to operate your
tractor at a much slower speed than you would
normally use. On the other hand sparse weeds
etc., may enable you to operate at a higher
rate of forward speed that would normally
be used under regular cutting conditions.
OPERATION
TROUBLE SHOOTING HINTS FOR SICKLE
BAR MOWER OPERATION WITH HYDRO¬
STATIC DRIVE TRACTORS:
Operation of hydrastatic drive tractors
enables a wide variance of forward speed at
a single throttle setting without necessarily
taking into consideration the type of material
that is being cut. Listed below arc some of the
tell-tale signs which will indicate when you
are operating your tractor in excess of reas¬
onable performing speeds:
1. Jagged or uneven cutting indicates too
fast a forward ground speed.
2. Plugging knife assembly could be created
by either excess forward speed, improper
lead adjustments, improperly installed hold
down clips , dull sickle knife or incorrect
pitch angle setting of sickle bar.
10
Cutting of heavy, short undergrowth, inter-
mingleil with tall weeds may rwjulre a slower
forward speed than would normally be used
for weed mowing. Be certain that your sickle
knife assembly Is alway.^ kept sharp.
SPECIAL CAUTION: Never attempt to force
the .sickle bar mower to raise, if the outer
end of the bar is lodged or caught in foreign
debris, dirt or heavy underbrush. Give your
tractor and the equipment every possible
opportunity to operate efficiently. Attempt to
reverse tractor or move forward carefully
until mower bar is released from entangle¬
ment or — stop engine--set parking iirake -
disengage PTO clutch, dismount from tractor
and release mower bar from entanglement
manually, then proceed.
Remember, always keep engine running at full
throttle when mowing - regulate forw^ard .speed
