OPERATING THE MOWER:
Follow tractor broak-in instructions as ex¬
plained in your Tractor Operator's manual.
Do not operate mower or any other attach¬
ments during this period. Check all other
tractor and engine operating adjustments be¬
fore starting to mow.
PRE-STARTING INSPE('1*ION:
1. Be sure mower lias been properly as¬
sembled to tractor. Assembly instructions
start on page 16.
2. Be sure mower is adjusted.
3. Check condition of mower blades. Keep
blades sharp.
STARTING THE MOWER
1. Shirt tractor engine at half throttle.
Always advance throttle lever to full posi¬
tion when moving.
2. Engage mower clutch.
NOTE: Prolong the life of mower drive belt
by engaging mower slowly.
STOPPING THE MOWER:
To stop sickle bar mower,)
Use tractor P.T.O. clutch on dash of tractor
MOWING
ME THOD OF MOWING:
Before mowing a new plot of grass, always
stop to analyse the area of field for best
mowing procedure. Consider also the height
of grass to bo mowe<i. type of terrain (level,
hilly or pitted), as well as the presence of
rock or trash. Each condition will require
certain adjustments or precautions, as out-
line<l In the following pages.
CAUTION: Pick up all rocks, stones and other
debris you can f ind be fore mowing inane w area.
Enter the area cautlonsly.
CAUTION: Before servicing machine, disen¬
gage power, shut off engine, and disconnect
engine spark plug cable.
Sickle bar mower can operate from 90 vertical
to 45 below horizontal. It may be necessary
to release some tension on the tor.sion spring
to allow mower bar to drop to lowo.st angle

of cutting. Sickle knife should have a clearance
of 1/32" from hold down clips. If hold-down
clips arc too tight, excessive vibration will
occur and sickle knife assembly will run hoi.
If several years of dead grass has accumu-

or slopes. It may bo necessary to cut against
the slope due to deail material leaning for¬
ward, thereby not allowing the sickle knife to
cut cleanly.
Test pattern cutting will soon show you the
most appropriate way to approach the task.
Hemcmlxrr. proper settings, sliurp sickles,
correct forwanl speed, and attunllon to gen¬
eral m«iintenance will enable you to cut any
reasonable patch of ground with sulisfuctfon.
Overlooking any one of th<j above points may
deter from the machine's performance. A few
points are listed below;
OPERATING SICKLE BAR MOWN RON TRAC¬
TORS WITH HYDROSTATIC DRIVE;
Proper ground speed for mowing depends upon
(1) the height, density, and type of grass to
be cut and (2) field or yard conditions.
When mowing, always operate engine at full
throttle. This is necessary to maintain proper
blade speed and to cause maximum flow of
air to cool engine.
Operation of hydrostatic drive tractors
enable you to easily obtain the projier ground
speed needed for best mowing performance
with the Sickle Bar Mower. A short amount
of testing when starting to mow in the various
conditions that you find, will enable you to
determine the most appropriate speed for that
particular condition. Too fast a forward ground
speed will cause problems as outlined under
paragraph three as listed above and can be
corrected as indicated in the solution.
