STEP 2: (SEE FIGURE 2)  
Use figure 2 to help identify the mounting holes for  
Sears tractor frames. For other brand tractors, identify  
the two mounting holes by placing a frame bracket  
against the tractor frame in front of the front axle and  
finding two holes in the tractor frame that align with  
two of the holes in the frame bracket The bracket can  
be flipped over to reverse the hole pattern. Refer also  
to the illustrations on page 9  
REMOVAL OF PARTS FROM CARTON  
Remove the loose parts and the hardware packages  
from the carton. Lay out all parts and hardware and  
identify using the illustrations on pages 4 and 5.  
Remove any bolts found in the mounting holes.  
On Sears tractors, remove the browning shield from  
the front of the tractor as shown.  
IMPORTANT: You will not use all of the parts or hardware  
supplied with your blade. Dispose of unused parts or  
hardware after you have finished assembling the blade.  
IMPORTANT: Be sure to reattach the browning shield in  
step 3  
CAUTION: Do not begin assembling  
until the tractor engine, muffler and exhaust  
deflector have been allowed to cool off.

deck or any other attachment you may have mounted  
to your tractor. Mark and save all removed parts.  
STEP 3: (SEE FIGURE 3)  
IMPORTANT: Right hand (R.H.) and left hand (L.H.) are  
determined from the operators position while seated on  
the tractor.  
Attach a frame bracket to each side of the tractor  
frame. On Sears tractors use a 3/8" x 1" hex bolt  
(E) and 3/8" lock washer (O) in the lower hole and a  
3/8" x 1" carriage bolt (H) and 3/8" nylock nut (K) in  
the upper hole of each frame bracket. Leave out the  
upper bolt if there is no hole in the tractor frame. Do  
not tighten. For other brand tractors use the bolts  
and nuts shown in the illustrations on page 9.  
On Sears tractors re-attach the browning shield  
STEP 1: (SEE FIGURE 1)  
Look under the front of your tractor. If there is a single  
mower deck suspension bracket located underneath  
the middle of the front axle, continue on to step 2  
If not, skip to step 7 on page 8 for tractors with dual  
mower deck suspension brackets.

CAUTION: Inspect carefully the area  
to be worked before operating the snow  
blade. Avoid pipes, roots, curbs or other  
heavy obstructions.  
Using the Snowblade  
Wheel weights and tire chains must be used with your  
snow blade for traction. These accessories are available  
at your nearest Sears retail store. See page 3.  
Prepare the lawn tractor engine for cold weather using  
instructions furnished with the lawn tractor.  
CAUTION: Know the terrain. Avoid  
exceptionally steep slopes or drop offs  
which may be hidden by the snow.  
Never run the snow blade into heavy  
material at high speed.  
Always begin with the transmission in first (low) gear  
and gradually increase speed as required.  
Do not repeatedly push snow in the same direction,  
causing excessive build up with each successive pass.  
To reduce icing on the blade, allow the lawn tractor  
and blade to adjust to outdoor temperature before  
operating.  
CAUTION: Always lower the blade to  
the ground before leaving the tractor.  
For improved snow removal performance, coat the blade  
with automotive type paste wax.

SERVICE AND ADJUSTMENTS  
To Adjust the Blade Pivot Lock Mechanism  
To Adjust Blade Spring  
If the blade will not unlock and pivot, the angle lock  
bars are not disengaging from the slots in the pivot  
plate. To correct, adjust the 5/16" hex jam nuts to draw  
the end of the control cable back towards the cable  
mount bracket. The less the threaded end of the cable  
extends through the bracket, the more the angle lock  
bars can retract to disengage from the slots in the  
pivot plate. See figure 29.  
The tension of the blade adjust spring may be altered  
to permit the blade to tilt forward to bypass solid  
obstructions. To change the spring tension, adjust  
the nuts at upper end of the spring bolt. Turn the nuts  
counterclockwise to relieve tension and clockwise to  
increase tension. Refer to figure 19 on page 12.  
To Adjust Blade Shoes  
The blade shoes at the ends of blade may be raised  
for close work on smooth surfaces or lowered to raise  
the blade to work on rough or uneven areas. Make  
sure both shoes are set evenly and that the nuts are  
tightened securely. See figure 28.

Recommendations When Storing  
To Remove Blade From Tractor  
When the snow blade is not being used, remove all  
dirt and rust and touch up with paint.  
Lower the blade head to the ground with the blade in  
the center (straight ahead) position.  
Touch up bare metal with paint or apply a light coat of  
grease or rust preventive.  
Lubricate all pivot points and all points shown in figure  
27, page 15 in the maintenance section.  
Store in a dry area, protected from weather.  
Remove the two clevis pins which fasten the  
blade's hanger brackets to the tractor's mower deck  
suspension brackets (or frame brackets). See figure  
11 on page 10.  
Remove the clevis pin that fastens the blade's rear  
mounting bracket to the tractor's drawbar and drop the  
rear of the blade frame to the ground. See figure 10  
on page 10.  
Remove the frame brackets (if used). See figure 3 on  
page 6.
