OPERATION
PREADJUSTMENT [Refer to Fig. 5 and 6]
Note: During normal plowing, the right side Tractor Wheels
will be riding in the previously plowed furrow A furrow
is the cut area your plow makes when turning the soil,
An initial setting for your plow is required to cut the
first furrow on level ground The following pre-sets will
result in an approximate 5" to 6" plowing depth,,
Remove Stabilizer Bolts and Nuts from Sleeve Hitch
The plow must be free to move side to side on Hitch
Lower your Tractor Lift Handle and lock in Lowered
Position. You may need to Lower the "Attachment Depth
Control" on your Tractor to do this
e Mount the Plow to the Sleeve Hitch with the Hitch Pin
furnished with the Hitch Refer to Figure 1 and Table 1 to
select the proper mounting hole
e Adiust Lift Spring Tension on Hitch as required, see
Hitch Manual for instructions
e Adjust the Depth Crank of Plow until Point of
Plow Share is on the ground and the rear of Plow
Landside is approximately 1" off the ground. (Refer
to Figure 5)
Note: The Plow will appear to be angled to left,
This will allow the Plow to run level when the
Right Hand Tractor Wheels are in the plowed furrow°
eThe plowing depth is set by adjusting the
Tractor Sleeve Hitch Turnbuckle until Hitch Drawstrap
has about I" of slot exposed between Pin and end
of Slot. Loosen the Hex Nut on the Hitch
Turnbuckle to adjust it Make sureto retighten it
after adjusting
eAdjust the Plow Coulter to its highest position,
e Go and make your first two furrows as described
in the diagram (X to A and turn B to C )., Make
sure the Tractor Lift Handle is Lowered and Locked
into the down position. Plow in Third Gear and near
Full Throttle Raise the Plow to the Transport
Position when turning
e If your Plow is not plowing at 4"to 5" deep
on your initial two passes, readjust the Plow Depth
Crank by turning it clockwise (.,-e.) to go deeper
or counter-clockwise (.e_) to go shallower. (See
Fig 8) Make this adjustment ONE TURN at a time
until desired depth is obtained,
Note: The rest of the furrows will be made with
the Tractor Tires in the previously cut furrows;
therefore, the Pitch (Depth) of the Plow must be
readjusted to a 5" to 6" plowing depth,
Position your Tractor with the inside of the
Right (Side) wheels against the side of the
previously plowed furrow
Start plowing for a short distance and check the
depth of the furrow Adjust the Depth Crank Clock-
wise or Counter-Clockwise ONE turn at a time and
retry until the 5" to 6" depth is obtained
FIG,. 6
e After plowing depth is set with plow in furrow,
stop the Tractor and measure the distance from the
centerline of the Plow Coulter Axle Bolt---it
should be about 2"above the ground If it is not,
raise the Plow out of the ground and adjust the
Coulter up or down to obtain this dimension Be
sure to adjust side motion at thistime (See
Coulter Adjustment page 8)
TRACKING ADJUSTMENT (OPTIONAL)
Note: If the Plow appears to track to the left Standard and turning the Tracking Adjustment Bolt
while plowing, an adjustment is available to correct Clockwise ("_') two turns,, Retighten Hex Nuts
this condition (Refer to Figure 9) securely, Repeat Adjustment as necessary until plow
®The Tracking Adjustment is made by loosening both pulls straight at !0" from the adjacent plowed
.].[2" Hex .Nuts spcuring the Plow Bottom to the 7 swath

istopickup a handfulof soil androll it into
a "ball" If soildoesnotcrumble,it is too
wet,,tf thesoilistoo dry,it maybe difficult
for theplowto penetrateproperly
eAvoidlowareas,old roadways,paths,andother
placeswhere soil is overly packed
e Expect to have some difficulty plowing+ thick
sod, However, by using the proper settings for
Coulter, Hitch, and Crank, you should be able to
do a good job under most conditions,+
® Do not tighter+ Stabilizer Bolts, the plow must
be free to sway from side to side, (Refer to your
Hitch Manual)
o Your 10" Plow will generally work best at a
depth of 5 to 6 inches
PLOWING TIPS
Lay out your field to be plowed, and if
possible make it rectangular in shape
Note: It is easier to plow a few long furrows
than many short ones, Leave some room at each
end of the field for turning your tractor,
e ALWAYS LIFT THE PLOW BEFORE TURNtNGttt
eDo not plow too fast! Move steadily along so
that the earth will turn over and not fall back
into the furrow, In most soils, this is done at
FULL THROTTLE in Third Gear+
Note: If Plowing Speed changes, it may be
necessary to re-adjust the Depth Crank to maintain
desired plowing depth+
e In light soils, plowing may often be done in a
higher Gear, but if you travel too fast, the
furrows will be uneven and the dirt is apt to be
thrown rather than rolled over,+
TRACTION
eFour 55 lb weights are required Refer to diagram
for positioning them See your local Sears Store or
Catalog outlet for purchase of weights,
e Tire Chains: Tire Chains or Rear Chevron Tires
(Agricultural Tires) are also recommended with the
plow Again, see your local Sears Store or Catalog
Outiet or refer to your Tractor Owner's Manual for
tire size
e When plowing heavy clay soil or sod, it will
help to reduce the width of the plow cut, This
can be accomplished by hitching the plow one or
two holes to the LEFT of the recommended setting,

ADJUSTMENTS
COULTER ADJUSTMENT
Refer to Fig 7
eThe coulter should be adjusted to slice 2"to 3"
deep when plow is in the ground Make this
adjustment by loosening the two hex nuts which
secure the "U" bolt and then move the coulter
assembly standard up or down as required,
®Rotate the coulter assembly to the LEFT so that
the drive pin located in the standard prevents the
coulter from swinging into the plow beam or bottom,
now tighten the two hex nuts When properly
adjusted, the coulter will be free to swing OUTWARD
a limited amount only, to the LEFT of the beam,
Note: tn extremely hard soil, the coulter may
actually prevent the plow from penetrating the
surface Should this situation occur +,raise, or
remove the coulter entirely

TRACKING ADJUSTMENT
Refer to Fig 9
NOTE:
For most plowing conditions, the landside will
be properly adjusted (from Fig 2 assembly),
enabling the plow bottom to react like a rudder
while ground engaged But if the tip of the plow
share is too far LEFT of the beam, the plow will
tend to overcut and leave a ragged furrow wall
This condition can be readily corrected by making
the following adjustment
=_Loosen both 1/2" hex nuts securing plow bottom
to the standard and then turn the Tracking
Adjusting Bolt CLOCK-WISE two turns Retighten hex
nuts securely Repeat adjustment as necessary until
plow pulis straight behind tractor and is plowing

o Loosen the Hex Jam Nut against the Spring Bushtng

spring and reduces lift effort Retighten Jam Nut
e Operate the Hitch with the Lift Link Assembly in the Center Adjustment Hole in the Lift Arm
Assembly for most conditions, If spring adjustment does not result in acceptable lift effort, operate
the Hitch with the Turnbuckle Assembly in the Lower Adjustment Hole in the Lift Arm Assembly
Note: The Upper Adjustment Hole can be used for lighter weight attachments
CUSTOMER RESPONSIBILITY
The Moldboard should (after initial "scouring")
be kept in a smooth, polished condition Fine
sandpaper, steel wool, kerosene, naptha, etc may be
used to restore the finish on a rusty Moldboard
The Coulter Blade edge should be relatively
sharp, If sharpening is necessary, use a flat
file
0 Every 4 hours lubricate the Coulter Hub bearing
surface through the grease fitting
• For smooth operation and to prohibit the
formation of rust on the crank, keep a light
coating of oil on threads.
Note: When lubricating bearing, it is recommended
that you use multipurpose grease
