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 your tractor does not have a mower deck suspension bracket underneath the middle of the front axle, skip

to step 5 on page 7 for tractors with dua! suspension brackets.

STEP 2: (SEE FIGURE 2)

Remove the tractor hood. Refer to your tractor owners

manual for instructions on how to properly remove the hood.

,Remove the browning shield from the front of the tractor as shown. Hold onto the shield as you remove the second bolt to prevent it from falling.

NOTE: Reinstall the browning shield before using your tractor.

STEP 3: (SEE FIGURE 3)

,Fasten the R.H. side plate (bend facing out) to the front three holes indicated in the tractor frame. Use three 3/8" x 1" carriage bolts (J) and three 3/8" nylock nuts (Q). Fasten the rear of the side plate to the frame using a 5/16" x 1" carriage bolt (L) and a 5/16" ny!ock nut (V). If there is an engine mounting plate (shown with dotted lines) that prevents the side plate from resting flat against the tractor frame, use three large 1/2" washers (CC) as shims between the side plate and the frame. Tighten all bolts. Repeat for the LH. side plate.

,Reinstai! the browning shield removed in figure 2.

STEP 4: (SEE FIGURE 4)

,Place a 1/2" washer (EE) and then a short spacer (Y) onto a 1/2" x 1-1/2" hex bolt (C). Instal! the bolt in the bottom hole at the front of the R. H. side plate and secure it with a 1/2" nylock nut (P). Repeat for the L.H. side plate,

Skip to step 8 on page 8.

STEP 6: (SEE FIGURE 6)

,Fasten the R.H. side plate (bend facing out) to the two holes indicated in the tractor frame. Use two 3/8" x 1" hex bolts (F) and 3/8" lock washers (Z). If the bolts insert loosely into the tractor frame, use two 3/8" nylock nuts (Q) on the inside of the frame. Repeat for the LH. side.

CONTROLS

Become familiar with all of the controls and adjustments on the tractor and dozer blade before operating. Refer to tractor owners manual for tractor controls. Controls for operating dozer blade are as follows:

LmFT HANDLE: (Figure 32)

Located on right hand side of tractor. To raise the dozer blade, push the lift handle down until blade locks in the up position. To lower the dozer blade, push down slightly on the lift handle, depress trigger and then lift up on handle to lower the blade.

BLADE ANGLE HANDLE: (Figure 32)

Located on the left hand side of tractor. When dozer blade is in the up position, depress grip assembly

and push or pul! on handle to swivel blade to the right or left. Release grip assembly to lock the blade in the left, center or right position.

NOTE: Always raise dozer blade and lock in up position before moving blade angle handle.

USING "['HE DOZER BLADE

NOTE: Wheel weights and tire chains should be used with your dozer to improve traction. For additional traction, install wheel weight on rear of draw bar using a weight bracket kit and one wheel weight from a wheel weight kit. These accessories are available at your nearest Sears retail or catalog sales.

Prepare the tractor engine for cold weather by following the instructions furnished with the tractor.

Inspect the area to be worked carefully before operating the dozer blade. Avoid pipes, roots, curbs or other heavy obstructions.

Always begin transmission in first (low) gear and gradually increase speed as required.

Operate tractor at reduced speed when dozer blade trip springs are locked out. Refer to Service and Adjustment section.

,If blade is stored in heated area, allow tractor blade to adjust to outdoor temperature before operating to reduce icing on the metal surfaces.

,For improved show removal performance, coat the blade with automotive type paste wax.

CAUTION: Know the terrain, Avoid exceptionally sharp slopes or drop-offs which may be hidden by the snow,

WARNING: Hidden objects can cause sudden stops or change in direction

WARNING: Never run the dozer blade into heavy material at high speed.

CAUTION: Always tower blade to ground before leaving tractor

BLADE ANGLE LOCK BARS: (Figure 33)

if angle lock bars DO NOT completely disengage

from slots in pivot plate assembly, adjustment of cable is required,

ADJUST BLADE SPRINGS: (Figure 33)

To change spring tension, stand in front of blade assembly and adjust the nuts at the upper end of the springs= Turn counter clockwise to decrease tension and clockwise to increase tension=

Adjust spring adjustment nuts approximately 1" from end when moving snow or other light material, Keep spring tension light for safety, This frees the blade to spring trip and return if a hidden obstacle is encountered.

DOZER SPRING LOCKOUT: (Figure 34)

To lock dozer blade spring trip action for heavy dozer work, }nsta!l two 1/2" x 2o3/4" hex bolts (A) (included in hardware package,) Secure with two 1/2" nylock nuts (P).

FIGURE 35

CHECK FOR LOOSE FASTENERS

,During the operating season, check al! bolts, nuts and hairpin cotters to be sure they are secure.

CHECK SCRAPER AND SHOES FOR WEAR

,During the operating season, check the scraper and shoes for wear before each use. After extensive use and wear, the scraper bar may be reversed to utilize the unused top edge. See figure 36.

CLEAN BLADE

???During the operating season, clean the blade off after each use. Touch up any bare metal with paint or apply a light coat of grease or rust preventive.

LUBRICATE BLADE

Oil al! pivot points each season so they will work freely.
