SECTION 5: MAKING ADJUSTMENTS
WARNING: Never attempt to make any
adjustments while the engine is running,
except where specified in operator’s manual.
Shift Rod Adjustment
If the full range of speeds (forward and reverse) cannot
be achieved, refer to the figures marked 1,2, and 3 to
the right and adjust the shift rod as follows:
1. Place the shift lever in the fastest forward speed
position. Remove the hairpin clip which secures the
ferrule to the shift lever.
2. Rotate the shift arm counter-clockwise as far as it
will go.
3. Thread the ferrule up or down the shift rod until it
aligns with the hole in the shift lever behind the
handle panel. Resecure the ferrule with the hairpin
clip removed earlier.
Tire Pressure
• Before operating, check tire pressure and reduce
pressure to between 15 psi and 20 psi.
NOTE: If the tire pressure is not equal in both tires,
the unit may pull to one side or the other.
• Using a ½” wrench, loosen the upper and lower hex
nuts found on one cable adjuster.
• Grasp the metal cable housing and gently push
upward to take up slack (usually no more than 1/4inch) in the cable before retightening both hex nuts.
• Repeat on each of two cable adjusters until the
upper chute has full range in both directions.
Figure 4

Chute Assembly
The distance snow is thrown can be adjusted by
changing the angle of the chute assembly. To do so,
stop the engine by removing the ignition key and loosen
the plastic wing knob found on the left side of the chute
assembly. Pivot the chute upward or downward before
re-tightening the wing knob. See Figure 3.
Figure 3
Joy-Stick Cable Adjustment (If Equipped)
If the upper chute does not have full range upward-anddownward, the joy-stick cables can be adjusted to take
up slack. See Figure 4.

13
Drive Control
When the drive control is released and in the
disengaged “up” position, the cable should have very
little slack. It should NOT be tight.
Check the adjustment of the drive control as follows:
1. With the drive control released, push the snow
thrower gently forward. The unit should roll freely.
2. Engage the drive control and gently attempt to push
the snow thrower forward. The wheels should not
turn. The unit should not roll freely.
3. With the drive control released, move the shift lever
back and forth between the R2 position and the F6
position several times. There should be no
resistance in the shift lever.
If any of the above tests failed, the drive cable is in need
of adjustment. refer to the figure at the right and
proceed as follows:
• Loosen the hex jam nut on the auger control cable
“Z” fitting and rotate the coupling end of the cable
downward to provide more slack or upward to take
up slack. See Figure 5.
• Retighten the hex jam nut and repeat all three tests
to verify proper adjustment has been achieved.
Figure 5
Auger Control
Refer to Auger Control Test on Page 11 to adjust the auger
control.
Skid Shoes (style varies by model)
The space between the skid shoes and the ground can
be adjusted. See Figure 6.
• For close snow removal on a smooth surface, raise
skid shoes higher on the auger housing.
• Use a middle or lower position when the area to be
cleared is uneven, such as a gravel driveway.
CAUTION: Loose gravel can be picked up
and thrown by the auger, causing injury to the
operator and bystanders and/or damage to
the snow thrower and surrounding property.
• Adjust skid shoes by loosening the four hex nuts
(two on each side) and carriage bolts. Move skid
shoes to desired position.
• Make certain the entire bottom surface of skid shoe
is against the ground to avoid uneven wear on the
skid shoes. Retighten nuts and bolts securely.
Figure 6
Chute Bracket Adjustment
If the spiral at the bottom of the chute directional control
is not fully engaging with the chute assembly, the chute
bracket can be adjusted. To do so, loosen the two nuts
which secure the chute bracket and reposition it slightly
before retightening the nuts. See Figure 7.

MANUFACTURER’S LIMITED WARRANTY FOR:
The limited warranty set forth below is given by MTD LLC with
respect to new merchandise purchased and used in the
United States, its possessions and territories.
“MTD”warrants this product against defects in material and
workmanship for a period of two (2) years commencing on the
date of original purchase and will, at its option, repair or
replace, free of charge, any part found to be defective in
materials or workmanship. This limited warranty shall only
apply if this product has been operated and maintained in
accordance with the Operator’s Manual furnished with the
product, and has not been subject to misuse, abuse,
commercial use, neglect, accident, improper maintenance,
alteration, vandalism, theft, fire, water, or damage because of
other peril or natural disaster. Damage resulting from the
installation or use of any part, accessory or attachment not
approved by MTD for use with the product(s) covered by this
manual will void your warranty as to any resulting damage.
Normal wear parts are warranted to be free from defects in
material and workmanship for a period of thirty (30) days from
the date of purchase. Normal wear parts include, but are not
limited to items such as: batteries, belts, blades, blade
adapters, grass bags, rider deck wheels, seats, snow thrower
skid shoes, shave plates, auger spiral rubber and tires.
HOW TO OBTAIN SERVICE: Warranty service is available,
WITH PROOF OF PURCHASE, through your local authorized
service dealer. To locate the dealer in your area, check your
Yellow Pages, or contact MTD LLC at P.O. Box 361131,
Cleveland, Ohio 44136-0019, or call 1-800-800-7310 or 1330-220-4683 or log on to our Web site at
www.mtdproducts.com.
This limited warranty does not provide coverage in the
following cases:
a. The engine or component parts thereof. These items
may carry a separate manufacturer’s warranty. Refer
to applicable manufacturer’s warranty for terms and
conditions.
b. Log splitter pumps, valves, and cylinders have a
separate one year warranty.
c. Routine maintenance items such as lubricants, filters,
blade sharpening, tune-ups, brake adjustments, clutch
adjustments, deck adjustments, and normal
deterioration of the exterior finish due to use or
exposure.
d. Service completed by someone other than an
authorized service dealer.
e. MTD does not extend any warranty for products sold or
exported outside of the United States, its possessions
and territories, except those sold through MTD’s
authorized channels of export distribution.
f. Replacement parts that are not genuine MTD parts.
g. Transportation charges and service calls.
No implied warranty, including any implied warranty of
merchantability of fitness for a particular purpose,
applies after the applicable period of express written
warranty above as to the parts as identified. No other
express warranty, whether written or oral, except as
mentioned above, given by any person or entity,
including a dealer or retailer, with respect to any product,
shall bind MTD. During the period of the warranty, the
exclusive remedy is repair or replacement of the product
as set forth above.
The provisions as set forth in this warranty provide the
sole and exclusive remedy arising from the sale. MTD
shall not be liable for incidental or consequential loss or
damage including, without limitation, expenses incurred
for substitute or replacement lawn care services or for
rental expenses to temporarily replace a warranted
product.
Some states do not allow the exclusion or limitation of
incidental or consequential damages, or limitations on how
long an implied warranty lasts, so the above exclusions or
limitations may not apply to you.
In no event shall recovery of any kind be greater than the
amount of the purchase price of the product sold. Alteration
of safety features of the product shall void this warranty.
You assume the risk and liability for loss, damage, or injury to
you and your property and/or to others and their property
arising out of the misuse or inability to use the product.
This limited warranty shall not extend to anyone other than the
original purchaser or to the person for whom it was purchased
as a gift.
HOW STATE LAW RELATES TO THIS WARRANTY: This
limited warranty gives you specific legal rights, and you may
also have other rights which vary from state to state.
IMPORTANT:
Owner must present Original Proof of
Purchase to obtain warranty coverage.
