Removing the Mower

Note: Retain all parts for installing the mower on the traction unit in the future.

1. Park the machine on a level surface and disengage the

blade control (PTO).

2. Move the motion control levers to the brake position,

stop the engine, remove the key, and wait for all moving parts to stop before leaving the operating position.

3. Lower the height-of-cut lever to the lowest position.

4. Remove the hairpin cotter and clevis pin from the

front support rod on each side of the mower (Fig. 2).

7. Remove the hairpin cotter and washer at the mower

leveling brackets (Fig. 3) on each side of the mower.

8. Slide the brackets off of the mounting pin.

9. Slide the mower rearward and remove the mower belt

from the engine pulley.

10.Slide the mower out from underneath the tractor.

Assembling the Blade

1. Lift and rotate the channel assembly (Fig. 4) so that

the holes align with the lower blade mounts.

2. Slide the rod through the holes and secure it with two

cotter pins (1 inch) (Fig. 4).

Operation

Important This snow blade should be used for

plowing snow only.

Caution

If you hit fixed objects with the blade, the traction unit could stop abruptly, causing you to lose control, sustain personal injury, and equipment damage.

• Travel at a safe, slow speed.

• Check the area to be plowed and mark all fixed

objects so that you can avoid them.

Lowering and Raising the Blade

Use the lift lever to lower and raise the blade (Fig. 16). To rest the blade on the ground, put the lift lever in the

lowest position.

Adjusting the Blade Angle

There are five positions for the side to side angle of the blade. To change the blade angle, perform the following procedure:

1. Raise the blade.

2. Push the index lever forward with one hand (Fig. 17)

while positioning the blade with the other hand until you have reached the desired blade angle.

3. Release the index lever. Note: The angle pin must snap into the hole in the channel

to retain the blade position.

Setting the Blade Height

Adjusting the Blade Trip

Set the operating height using the following procedure.

1. Move the lift lever into the second lowest position.

2. Remove the cotter pin and clevis pin attaching the lift

rod to the lift arm.

Springs

The blade trip springs can be mounted in four positions. The top hole provides the greatest scraping pressure and the bottom hole provides the least scraping pressure (Fig. 19).

1. Remove the hairpin cotter and slide the rod from the

blade and springs (Fig. 19).

2. Slide the rod through the springs and the new hole

position in the blade (Fig. 19).

4. Move lift rod forward as far as possible and hold it in

that position (Fig. 18).

5. Turn the yoke to adjust the length of the lift rod

(Fig. 18). The lift rod is in position when the holes in the yoke line up with the lift arm.

6. Install the lift rod to lift arm using the clevis pin and

cotter pin removed previously.

7. Bend the end of the cotter pin to secure the clevis pin.

Tips for Using the Blade

To obtain the best possible results with your blade, follow these tips:

• Remove snow as soon as possible after it falls.

• Remove snow from a driveway by making one pass

down the center and then plowing snow to either side on successive passes.

Yearly/Storage Service

If you leave the key in the ignition switch, someone could accidently start the engine and seriously injure you or other bystanders.

Remove the key from the ignition and disconnect the wire from the spark plug before you do any maintenance. Set the wire aside so that it does not accidentally contact the spark plug.

Maintenance Procedure

• Grease the channel pivot.

• Oil the linkages.

• Grease the channel pivot.

• Oil the linkages.

• Examine the scraper for wear and replace if necessary.

• Paint any chipped surfaces.

Greasing and Lubricating the Blade

Caution

Grease and oil the blade after every 25 operating hours or once a year, whichever occurs first.

Grease type: general-purpose grease Oil type: SAE 10W or 10W30

Greasing the Channel Pivot

1. Lower the blade.

2. Set the parking brake, stop the engine, and remove the

ignition key.

3. Clean the area around the channel pivot with a rag. Apply grease to the pivot bolt, frame, and channel indexing holes (Fig. 20).

4. Wipe off excess grease.

Oiling the Linkages

1. Set the parking brake, stop the engine, and remove the

ignition key.

2. Place a few drops of oil on all movable linkages

(Fig. 20).
