Rider Model

Identification

To The Owner

Model OEM-190-032 two-stage snow thrower attachment is
designed for use on FastAttach™ Compatible Lawn Tractors
and Garden Tractors ONLY. It will NOT fit nor operate
properly or safely on ANY other tractor.

Determine The Model

of Your Rider

Since this manual is designed for installation of your new
snow thrower attachment on several different rider units,
it is important for you to determine which model of rider
you have. Therefore you will know which set of instruc­tions in the following pages to follow.

To determine which model of rider you have, you will
need to locate the rider’s model plate, located under the
seat. Simply flip the seat up and locate the model plate,
which will consist of an 11 digit/letter model number
and a serial number. For ease in this installation and
for future use, copy your rider’s model number & serial
number below now:

and RIGHT indicate the

the tractor when facing

forward in the operator’s

position. Reference to

the FRONT indicates the

grille end; to the REAR,

the rear end of the rider.

NOTE:

References to LEFT

left and right sides of

Figure 2

Rider Model Number:__ __ __ __ __ __ __ __ __ __ __

Rider Serial Number:_____ _____ ____________ ___

The 5th, 6th & 7th numbers from the left in your model
number determine your rider’s model series. See Figure 2.

When you fill in your model number in the space above,
the actual model series number should fall into the gray
shaded area.

Now that you have determined what model rider you
are attaching this snow thrower attachment to, follow
the instructions in the following pages according to your
model of rider. You can locate which instructions apply to
your model of rider by the gray-shaded area in the border
of each page. For instance, an 809 or 80R would signify
that you should follow the instructions for Model Series

800.

Operation

WARNING

Read, understand,

and follow all
instructions and
warnings on the

tractor, attachment,

and in the Operator’s

Manuals before

operating.

IMPORTANT:

The augers are secured

to the spiral shaft with

two shear bolts and hex

lock nuts. If you hit a

hard foreign object or

an ice jam, the snow

thrower is designed

so that the bolts may

shear. Two replacement

shear bolts and hex

lock nuts are provided

for your convenience.

Store in a safe place

until needed. NEVER

replace the auger shear

bolts with standard hex

bolts. Any damage to
the auger gearbox or

other components as a

result of doing so

will NOT be covered

by your snow

thrower’s warranty.

OPERATION

WARNING: Read, understand, and
follow all instructions and warnings
on the tractor, attachment, and in the
Operator’s Manuals before operating.

Your snow thrower attachment is capable of displacing
snow and clearing a path a width of 42 inches.

Observe the following operating instructions for efficient
snow removal.

1. Become familiar with and comfortable using all of
your tractor’s controls as instructed in your tractor’s
Operator’s Manual before operating it with the snow
thrower attachment.

2. Make certain the correct weight (and volume) of
motor oil in is your tractor’s engine as instructed in
the engine Owner’s Guide packed with the tractor’s
Operator’s Manual.

3. Always operate the snow thrower with the tractor’s
engine at maximum RPM (full throttle).

4. NEVER override any safety features on either your
tractor or the snow thrower attachment.

5. Make certain that all nuts, bolts, and hardware are
fastened securely and tight on both the tractor and
the snow thrower attachment prior to use.

6. Make certain snow thrower is assembled
properly and mounted to the tractor as instructed
in this manual.

8. Test all controls (tractor PTO, snow thrower lift
handle, chute tilt lever & chute crank) for smooth
operation prior to operating snow thrower in snow.

9. Make all adjustments (i.e. skid shoes, lift latch)
before operating your snow thrower attachment.
Follow instructions in the Adjustments section of this
manual when doing so.

10. Engage the tractor’s PTO to activate power to the
augers and impeller BEFORE driving the tractor
forward and into snow.

11. Keep your tractor’s ground-speed slow. The slower
your tractor is traveling, the more effectively the
snow thrower attachment can displace snow.

12. Adjust ground speed for snow conditions and
become familiar with different snow applications.
Your snow thrower attachment will operate differently
in wet heavy snow than it will it light, fluffy snow.

13. Overlap a previously cleared path when necessary
(deep snow) so as not to overload the auger housing
with snow.

14. NEVER drive the tractor into a snow bank. The
snow thrower attachment is not a dozer plow. The lift
linkage and/or the snow thrower drive system can
be damaged as a result of “plowing” with the snow
thrower attachment.

15. If the augers become jammed with a chunk of ice or a
foreign object, move the PTO into the disengaged (OFF)
position immediately and turn off the tractor’s engine
and remove the ignition key. Examine the auger area
thoroughly for damage and do NOT operate the snow
thrower attachment until any damage is repaired.

IMPORTANT: The augers are secured to the spiral
shaft with two shear bolts and hex lock nuts. If you hit
a hard foreign object or an ice jam, the snow thrower is
designed so that the bolts may shear. Two replacement
shear bolts and hex lock nuts are provided for your
convenience. Store in a safe place until needed. NEVER
replace the auger shear bolts with standard hex bolts.
Any damage to the auger gearbox or other components
as a result of doing so will NOT be covered by your snow
thrower’s warranty.

16. Whenever possible, discharge snow downwind.

17. Do NOT attempt to remove ice or hard-packed frozen snow.

18. When the tractor (with the snow thrower attachment
mounted) is not in service, use the lift lever to lower
the auger housing assembly to the ground to relieve
strain on the tractor’s front end between uses.

19. Always use tire chains and rear wheel weights on
your tractor where extra traction is needed. Refer to
the table to the right to determine which kits will fit
your tractor (tire dimensions are can be found on the
sidewalls of your tractor’s tires).

20. Use drift cutters to aid in displacing snow through
deep, drifted areas.

Making Adjustments

WARNING: Never attempt to make any

adjustments while the engine is running,
except where specified in the Operator’s
Manual. Place tractor on a firm and

level surface. Place the PTO in the disengaged (OFF)
position, set the parking brake, shut engine off, and
remove key to prevent unintended starting.

Lift Adjustment

If the lift index rod doesn’t latch securely or the pivot
release has too much slack in it, an adjustment can be
made as follows:

1. Loosen the upper hex nut a few turns, then tighten the
lower hex nut to shorten the cable length. See Figure 11–1.

2. Loosen the lower hex nut a few turns, then tighten the
upper hex nut to lengthen the cable. See Figure 11–1.

Lower Chute Crank

Support Bracket Adjustment

If the spiral at the base of the lower chute crank isn’t fully
engaging with the notches in the lower chute assembly,
the support bracket can be adjusted inward or outward as
follows:

1. Loosen, but do NOT remove the two hex nuts which
secure the support bracket to the snow thrower
housing. See Figure 11–2.

2. Adjust the support bracket inward or outward so that
the spiral is fully engaged in the notches on the chute
before retightening the hex nuts.

Skid Shoe Adjustment

The space between the shave plate and the ground can
be adjusted by repositioning the skid shoes found on
either side of the snow thrower’s auger housing. For close
snow removal, place skid shoes in the low position. Use
a middle or high position when the area to be cleared is
uneven.

IMPORTANT: It is NOT recommended that this snow
thrower be operated on a gravel surface, as loose stones
can be easily picked up and thrown by the machine. If
you must operate on a gravel surface, ALWAYS adjust the
skid shoes into the HIGH position to allow the shave plate
maximum clearance.

Adjust skid shoes as follows:

1. Loosen, but do NOT remove, the three hex nuts which
fasten the skid shoe to the auger housing.
See Figure 11–3.

2. Raise or lower the skid shoe to desired position.

NOTE: Make certain the entire base of both skid shoes
are against the ground to avoid uneven wear on the skid
shoes. When one side does wear out, the skid shoes are
reversible.

3. Retighten the hex nuts loosened earlier.

4. Repeat this adjustment on the skid shoe found on the
opposite side of the snow thrower.
