vrcnAf lNG CONTROLS
The principle components and controIs of
your rotary mower are identified in Figure
1 with the same description used through-
out this manual.
All controls are conveniently located near
the operator's position on the tractor. The
mower bIades are placed in motion by en-
gazing the tractor attachment drive clutch
lever, The desired mowing height can be
quickly adjusted with the height selection
knob. See inset photo, Fighe 1, Generally
best performance is obtained with the trans-
mission in "bw" range and the engine run-
ning approximately 314 throttle. The throttle
shodd be set as low as practical to obtain
maximum fuel eCOndllly but high enough te
prevent erigine lug-down or labor which could
cause overheating and poor mowing. Ad-
just the tractor ground speed with the Travel
lever according to your mowing conditions.

ditions. As a general rule, set the
throttle as low as practical .to obtain
maximum fuel economy but high enough
to avoid engine lug-down or labor which
could cause overheating. Unless grass
is unusually light, always operate in
"Lawt' speed range.
Lf grass is heavy and higher than normal,
results can be improved by mow twice.
Make the first cut with the mower set
higher than normal; then repeat with the
mower set at desired finished cut height,
When mowing heavy grass, always dis-
charge clippings away from the uncut

getting on or off the tractor. If mounting
the tractor from the right side, place
your sight foot on the right foot rest,
your right hand on steering wheel and
left hand on the seat back and step onto
the tractor, swinging your left foot
through between the steering wheel an&

ADJUSTMENTS AND MAINTENANCE
1, Height Selection Lever: See Figure 4
The mower cutting height is adjustable
from 1-1/2" to 3-1/2" with 112" settings
available in between. To change the
cutting
height, pull outward on the se-
lection knob, move the lever up or down
to desired height setting and push back
into matching hole. Relieve the weight
an the selection lever by raising the
mower into transport position before ad-
justing the cutting height, Always op-
erate the mower with the gauge wheels
on the ground and all weight off the
mower lift Ws to obtain a level and
uniform cut,
/MPRrA#f When the cutting height is
changed, readjust the
Depth Control Knob as ex-
plained in the following .

Ad-
justed in this manner the mower is free

a(b TE When turning the Depth Control
Knob, the Eft lever must be in the
raised (transport) position so the
lift lever stop plate is not in con-
tact with the depth control rod.
You may find it useful for future
reference to mark the position of
the depth indicator on the decal
when the depth control md is cor-
rectly adjusted to your desired
cutting height.
3. Mower Blade &Its:
Before operating the mower for the first
time, check the bolts holding the blades,
THEY MUST BE TIGHT. After the first
8 hours operahon, check them again.
Whenever the blades are removed, it
is a good practice .to install new lock-
washers 'mder the bolts, and again check

Complete tractor and engine maintenance
bstructions are outlined on pages 12
and 13 of your tractor Operator's Man-
ual, When rnotvinz, give particular atten-
tion to the areas which are affected by
grass accumulation. Check and brush
off the engine air intake screen and
heat exchanger fins DAILY.
Also check
and clean the engine air cleaner element
daily as explained on page 21 of your
tractor manual. If mowing under par-
ticularly dry or dusty conditions a "Pre-
cleaner," part number K0237421, is
available through your J I Case Dealer
which fits over the regular element
See Figure 8. This precleaner can be
washed out with soap and water as nec-
essary which will extend the life of the

ment should become iry, locate
the tractor and mowe Ievel sur-
face and place the Height SeIector Lever
in the 2-I/2" s~tting before making ad-
justrngqts. To raise the front of the
mower, first loosen the outer nut on
each link and then equally turn the in-
ner nuts r~sr~vard. To lower the front
of the mower, loosen the her nut on
each link and turn the outer nuts fore-
. ward. Check blade heights as close to
the front and rear edges of the mower
as possible. Distance between the blades
and the level surface should be the same
at both front and rear edges of mower.
7. Mower Gauge Wheels:
See Figure 9
Remove the gauge wheels after each
10 hours of mowing and lubricate the
bushings and axle bolts with chassis
grease.
mff& an alternate to grease the wheels
can be oiled each four hours of op-
eration. Make sure the oil pene-
trates to the hide of the bushings
by holdiig the deck at a slanted
angle while lubricating.
8, Mower Deck Belt Replacement: See
Figure 10
The deck belt is automaticalIy tensianed
by a spring loaded ider pulley and does
not require adjustment, If a new belt is
installed, place it around the three
spindle pulleys as illustrated. Place a
9/'16" box wrench over the hex nut on
the idler pulley and pivot L!e pulley
towards the fmnt of the mower until
the belt can be easily placed over the
back side of the idler as shown. Check
to make sure the belt is not rolled or
twisted before replacing covers.

9. Sharpening Blades: See Figure 11
Check the mower blades periodicalIy for
nicks or dullness. Damaged or dull
blades can cause a shattered rather than
clean cut and brown areas may develop.
The left picture, Figure 11, il!ustrates
the correct angle at which to resharpen
the blade cuttmg edges. If the cuttk~g
edge is sharpened at a blunt angle as
shown in the right picture, the grass

f 0, Edancing Blades: See Figre 12
+tctor a blade Is sharpened, check it for
balance by inserting a dowel or hlt in
t5e center hole and place between two
level edges as shown in Figure 12. A
balanced blade will center itsell so the
cutting edges are parallel with the edges.

wrappings between the blade mounting
plates and the spindle housings. Grass

due to width. Model H44 and H46
Eowers are shlpped with four straight

a) Mowers With Offset Lift Links:
Use the upper slat in the lift links
when xounting the mewer on th~ Model
442 or 444 tractors. On Model 220
