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.

Installing Lift Rod
1. See Figure 24. Assemble clevis (M) to lift rod (A).
Turn clevis into rod about halfway.
2. See Figure 24. Install the lift rod assy. (A) to the
lift arm assy. bracket. Secure with pin (B) and
cotter pin (C) supplied with snowthrower.
3. See Figure 24. Attach the large spring (D) to the
bracket from the top as shown.
4. See Figure 24. Loosely mount the spring brack-
ets (E & F) to the hitch using hardware supplied
(G, H & I).
5. Position the manual lift fully to the rear.
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.
