40” TWO-STAGE SNOWTHROWER

Installing Lift Rod

1. See Figure 15. Assemble clevis (A), rod exten-

sion (B, for electric model only), and nut (C) to lift

rod (D). Turn rod extension and clevis into rod

about halfway. Do not tighten jam nut at this

time.

2. See Figure 15. Install the lift rod assy. (D) to the

electric lift arm assy (E). Secure with pin (F) and

cotter pin (G) supplied with the snowthrower.

3. Turn the ignition key on. See Figure 15. Activate

the electric lift until the lift rod clevis (A) aligns

with the front hitch bracket. Secure the clevis to

the hitch bracket using the pin (H) and hairpin

clip (I) supplied with the snowthrower.

4. Adjust snowthrower lift height by turning clevis in

or out to achieve desired lift height then tighten

nut against clevis. Average snowthrower lift

height is 6".

NOTE: Snowthrower lift height affects the amount of

downward pressure applied to the

snowthrower. Lengthening the rod increases

lift height and decreases downward pres-

sure while shortening the rod decreases lift

height and increases downward pressure.

Reverse Electric Lift Wiring

The electric lift control switch on dash is used to lift

or lower the mower deck and front attachments on

the tractor. Pushing the top of the switch lowers the

mower/attachments while pushing the bottom of the

switch raises the mower/attachments.

This 40" snowthrower attachment, when attached to

the existing switch, works in the opposite manner.

For the switch to work properly with this attachment,

it is necessary to reverse the wiring at the electric lift

motor assembly as follows.

1. Locate the two wire leads (A and B, Figure 16) con-

nected to the electric lift assy. You will find them

under the seat deck and in front of the right, rear

wheel.

2. Reverse the position of the two leads in the

wiring harness.

3. The snowthrower will now work properly with the

lift control switch.

NOTE: Change the wires leads back to their original

position when removing snowthrower so

switch operating position is correct for

mower and other attachments.

6. See Figure 24. Attach the eye hook (J) to the

spring (D) and then fasten it to the bracket (E)

using the flat washer (K) and nut (L). Threads

should protrude through bracket just enough to

start the nut onto the eye hook.

7. Tighten the bracket (E & F) mounting hardware

securely.

8. Hold the eye bolt to keep it from turning and tight-

en nut to the end of eye bolt threads.

9. Position the manual lift lever fully forward.

10.See Figure 24. Turn clevis (M) until it aligns with

mounting hole on hitch. Connect the clevis to the

hitch using the pin (N) and clip (O) supplied.

11.Adjust snowthrower lift height by turning clevis in

or out to achieve desired lift height. Average

snowthrower lift height is 6".

NOTE: Snowthrower lift height affects the amount of

downward pressure applied to the

snowthrower. Lengthening the rod increases

lift height and decreases downward pres-

sure while shortening the rod decreases lift

height and increases downward pressure.

REMOVING THE SNOWTHROWER

Remove the snowthrower by reversing the steps out-

lined in the Installation procedures. Please note the

following:

Install all pins and hairpin clips into appropriate hole

locations on hitch and snowthrower for storage.

NOTE: On models equipped with electric lift,

change the electric lift wires leads (A and B,

Figure 25) back to their original position

when removing snowthrower so switch oper-

ating position is correct for mower and other

attachments. See Reverse Electric Lift

Wiring on page 10.

WARNING

To avoid personal injury, use extreme care

when removing spring from lift lever and

hitch. Place lift lever fully rearward and

loosen eyebolt hardware (K & L, Figure 24)

before attempting to remove spring.

WARNING

Before performing adjustments, stop the

engine and remove the key. Place tractor

and snowthrower on a level surface.

Engage the tractor parking brake. Wait for

all moving parts to stop.

ADJUSTMENTS

NOTE: The following adjustments apply to the

snowthrower only. See your tractor

Operator's Manual for any necessary tractor

adjustments.

Belt Adjustment

See Figure 26. Turn belt adjuster handle (C) until

trunnion (A) is located between the marks shown.

NOTE: If trunnion cannot be placed between marks,

loosen capscrew (D) and reposition idler pul-

ley (E) as necessary.

Scraper Adjustment

The snowthrower assembly can be tilted forward

to achieve increased scraper contact with ground.

1. To adjust snowthrower angle, loosen the two

capscrews on each side of the snowthrower as

shown in Figure 27.

2. Tilt snowthrower forward to desired angle and

tighten the capscrews.

Skid Shoe Adjustment

When operating on a smooth, hard surface such as

concrete or asphalt, adjust the skid shoes to allow

3/16" - 1/4" clearance between scraper bar and

ground surface.

When operating on a rough surface, such as gravel,

adjust the skid shoes to allow 1/2" - 5/8" clearance

between scraper bar and ground surface.

1. Rest each side of the scraper bar on wood blocks

about one inch high, with scraper bar level with

ground surface.

2. See Figure 27. Loosen the hardware holding

each skid shoe and move the skid shoes up or

down.

3. With both skid shoes adjusted properly and par-

allel to the ground surface, tighten hardware

securely.

Auger Drive Chain

Chain tension should be set so that deflection in the

middle of the chain is 1/2".

1. See Figure 28. Loosen the two idler arm bolts

located on the right side of the snowthrower

housing.

2. Adjust tensioner to achieve proper chain deflec-

tion, then tighten both idler arm bolts.

Deflector

The position of the deflector determines the height

and distance snow will be thrown. Most snow throw-

ing can be done with the deflector all the way up.

To adjust, loosen both hand knobs (Figure 28) on

each side of the deflector, position deflector to

desired position then tighten both knobs.
