Assembling the Blade
1. Lift and rotate the channel and trip spring assembly so
that the holes align with the lower blade mounts.
2. Slide the rod through the holes and secure with two 1
in. cotter pins (Fig. 2).
Note: If you have difficulty sliding the rod through the
holes, partially remove the upper rod and use a hammer to
drive the rod through. Then, install the upper rod.
3. Bend the ends of the cotter pins to secure the rod.

it with a bolt (3/4–16 x 3-3/4 in.) and a locknut
(3/4 in.) (Fig. 4).
Note: Insert the bolt up from the underside of the frame
(Fig. 4).
Important Do not tighten the nut and bolt excessively,
thereby causing binding on the channel as it pivots from
side to side.
Mounting the Rear Hitch on the
Tractor
Center the hitch on the axle housing and secure it using 4
carriage bolts (3/8 x 3-1/2 in.) , 2 straps, and 4 locknuts
(3/8 in.) as illustrated in Figure 5.
Note: On hydrostatic models with the oil filter facing the
rear, install the hitch 3-1/4 in. (8.3 cm) from the right side
of the center housing.
Note: On 8-speed gear drive models, install angle spacers,
positioned along top and rear of axle (Fig. 5).

Operation
Caution
If you hit fixed objects with the blade, the tractor
could stop abruptly, causing you to lose control,
personal injury, and equipment damage.
• Travel at a safe, slow speed.
• Check the area to be plowed and mark all fixed
objects so you can avoid them.

Raising and Lowering the
Blade
Depending on your tractor model, it will have either a
power or a manual lift lever (Fig. 12 and 13) to raise and
lower attachments.
Raising the Blade Using a Power Lift
Lever
1. Turn key to the On or Run position.
2. Push the lift lever up to raise the attachment lift
(Fig. 12).
Lowering the Blade Using a Power Lift
Lever
1. Turn key to the On or Run position.
2. Push the lift lever down to lower the attachment lift
(Fig. 12).
7
Raising the Blade Using a Manual Lift
Lever
1. Stop the machine.
2. Pull the attachment lift lever rearward until the blade
raises and the latch locks (Fig. 13).
Lowering the Blade Using a Manual Lift
Lever
1. Stop the machine.
2. Pull attachment lift lever rearward, to release lift
pressure and push the button on top to release the latch
(Fig. 13).
3. Move the lift lever forward to lower the blade (Fig.13).
Adjusting Dial-A-Height
The Dial-A-Height control (Fig. 13) is used to adjust the
downward travel of the attachment.
2. Push or pull the handle to change the angle.
3. Release the lever and pull or push the handle until the
locking pin on the blade snaps into place.
Adjusting the Blade Trip
Springs
You can mount the blade trip springs in four positions.
The top hole provides the greatest scraping pressure and
the bottom hole provides the least scraping pressure
(Fig. 15). Toro recommends using the second hole from
the top for removing snow.
1. Remove the hairpin cotter and slide the rod from the
blade and springs (Fig. 15).
2. Slide the rod through the springs and the new hole
position in the blade (Fig. 15).

1. Raise the attachment lift.
2. Rotate the Dial-a-Height knob to change the stop
location.
Turn the knob clockwise to raise and counterclockwise
to lower the height of the attachment.
Adjusting the Blade Angle
You can turn the blade from side to side, in 5 positions.
You control the angle using the control handle (Fig. 14).

Tips for Using the Blade
The following lists contains information that will help you
obtain the best possible results with your blade:
• 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.
• If the tractor looses traction when using the snow
blade, install wheel weights and/or tire chains, which
are available from your Authorized Service Dealer.
• Install the optional skid shoe kit is to control the height
of blade from the ground for even scraping if desired.

Yearly/Storage Service
Maintenance Procedure
• Grease the channel pivot
• Oil the linkages
• Grease the channel pivot
• Oil the linkages
• Examine the scraper for wear and replace if damaged or worn
• Paint chipped surfaces (Paint is available from your Authorized Service Dealer.)
Caution
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.
Greasing and Lubrication
Grease and oil the machine after every 25 operating hours
or once a year, whichever occurs first.
Grease Type: General-purpose grease.
Oil Type: SAE 10W or l0W30.
Grease the Channel Pivot
1. Lower the attachment.
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 sector
(Fig. 16).
m–1473

4. Wipe off excess grease.
Oil 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. 16).
3. Wipe off excess oil.

Reversing the Scraper Blade
The scraper blade contacts the ground, preventing damage
to the snow blade. Periodically inspect the scraper blade
for wear. When the scraper becomes worn, before the
working surface contacts the housing, reverse the scraper
blade.
1. Start the tractor, raise the blade, and support the
housing off the ground.
2. Set the parking brake, stop the engine, and remove the
ignition key.
3. Remove the locknuts and carriage bolts securing the
scraper (Fig. 17).
4. Reverse the scraper blade to replace a worn edge and
install it with the previously removed hardware
(Fig. 17).
