UsingYourTiller

Your tiller (also known as a cultivator) is a precision
built machine designed for seed bed preparation,
cultivating, furrowing and mulching. It is engineered to
minimize the hardest work in the vegetable or flower
garden, to till the soil for planting and cultivating, and to
perform many other useful labor saving tasks in the
garden.

WheelPosition

The tiller is shipped with the wheels adjusted such that
the unit sits level. While tilling, as the tines enter the
ground and the front of the tiller lowers, the wheels

must be raised to level the unit, which is essential for
proper engine operation. This adjustment is made by

removing the clevis pin and hairpin clip from wheel
yoke, raising the wheels to the desired height, and
replacing the clevis pin and hairpin clip. See Figure 5.

Hairpi_
& Clevis Pins

Figure 5

ControllingSpeedAndTillingDepth

WheelYokeAdjustment

Place wheel yoke so that the wheels are forward
(nearest point between wheels and tines) for shallow
tilling, cultivating and transport. The forward speed will
increase. Turn yoke around (farthest point between
wheels and tines) for deep tilling. Forward speed will
decrease. See Figure 6.

Yoke _ition Wheel

Figure 6

DepthStakeAdjustment

The depth stake acts as a brake for the tiller and
controls the depth and speed at which the machine will
operate. Remove the clevis pin and hairpin clip to raise
or lower depth stake. Refer to Figure 5.

By increasing the depth of the depth stake, the forward
speed of the machine is reduced and the working depth
is increased. When the depth stake is raised, the
working depth of the machine is reduced and the
forward speed is increased. The working depth of the
machine may be predetermined by setting the depth

stake and wheels so that the wheels are about four
inches from the ground when the tines and depth stake

are resting on the ground. This setting will permit a
working depth of about four inches. When presetting
the working depth, the handles should be adjusted so
the hand grips are a little above waist. The tiller will be
lower when the tines and depth stake penetrate the
ground. See Figure 7.

Transport De

Position

Shallow
Tilling S

When tilling, leave approximately 8 inches of untilled
soil between the first and second tilling paths, then
make the third path between the first and second. In
some soils, the desired depth is obtained the first time
over the garden. In other soils, the desired depth is
obtained by going over the garden two or three times. In
the latter case, the depth stake should be lowered
before each succeeding pass over the garden. Passes
should be made across the length and width of the
garden alternately. Rocks which are turned up should
be removed from the garden area. See Figure 8.

Figure 8

HandlePressure

Further control of tilling depth and travel speed can be
obtained by variation of pressure on the handles.

• A downward pressure on the handles will reduce
the working depth and increase the forward speed.

• An upward pressure on the handles will increase
the working depth and reduce the forward speed.

The type of soil and working conditions will determine

the actual setting of the depth stake and the handle
pressure required.

TransportingtheTiller

• To transport the tiller to or from the garden, pivot
the depth stake forward and out of the way. With
the throttle control in SLOW position, the unit will
walk freely on the lawn. If the operator does not
allow the tiller to move freely, the unit will start to till
the surface. Refer to Figure 7.

Cultivating
For cultivating, a two to three inch depth is desirable.

Setting the wheels and depth stake so that the wheels
are about two inches above the ground while the tiller is
resting on the tines and depth stake will allow the
machine to work at cultivating depth. The throttle

should be set to control forward movement to a slow
walking speed. With the outer tines installed, the

working width of the machine is 22 or24 inches.

SECTION5: MAKINGADJUSTMENTS

The tiller has many uses other than tilling and
cultivating a garden. One of these is the preparation of

lawn area for seeding. The tiller will prepare a deep
seed bed which will be free of hard untilled spots,

allowing a better stand of grass to grow. The tiller is
very useful for loosening hard soil for excavation with a

shovel. No tedious handwork will be necessary. Your
tiller may be used for mixing compost in the pile, or for

mixing it with the soil in your garden. This should be
done after the soil has been broken to the full working

depth. The compost should be worked in to a depth of
six to seven inches. This may be done by working the

length of the garden and then by making separate
passes across its width. The addition of decayed

organic matter will substantially increase the fertility of
your garden. For proper decaying action, fertilizer

should be applied and worked in with the mulch
materials. Breaking up leaves and straw and mixing it

with several inches of soil causes the soil to hold
moisture longer and allows proper aeration of the plant

root system. This also retards the growth of weeds.

WARNING: Disconnect the spark plugwire and ground it against the engine

before performing any adjustments.

EngineAdjustment

Refer to the separate engine manual for engine

adjustment instructions.

WheelAdjustment

To adjust the wheel yoke and wheel position, refer to
the Operating Section.

DepthStakeAdjustment

To adjust the depth stake to a desired position, refer to
the Operating Section.

ClutchControlAdjustment

Periodic adjustment of the belt tension may be required
due to normal stretch and wear on the belt. To adjust
the clutch control lever, refer to the Assembly Section.

TineWidthAdjustment

The tilling width of the unit is22 inches. Tilling width can
be increased to 24 inches by removing the clevis pins
and hairpin clips, sliding the outer tines out one inch,
and securing in this position with the clevis pins and
hairpin clips. For cultivation, reduce the tine width to 13
inches by removing the outer tines completely.

WARNING: Disconnect the spark plug

before performing any repairs or
maintenance.

Engine

Refer to the separate engine manual for engine
maintenance instructions.

Maintain engine oil as instructed in the separate
engine manual packed with your unit. Read and follow
instructions carefully.

Service air cleaner every ten hours under normal
conditions. Clean every hour under extremely dusty
conditions. Poor engine performance and flooding
usually indicates that the air cleaner should be
serviced. To service the air cleaner, refer to the
separate engine manual packed with your unit.

IMPORTANT: Never run your engine without air cleaner
completely assembled.

The spark plug should be cleaned and the gap reset
every 25 hours of engine operation. Spark plug

replacement is recommended at the start of each tiller
season; check engine manual for correct plug type and
gap specification.

Clean the engine regularly with a cloth or brush. Keep
the cooling system (blower housing area) clean to
permit proper air circulation which is essential to engine
performance and life. Be certain to remove all dirt and

combustible debris from muffler area.

Clean the underside of the tine shield after each use.
The dirt washes off the tines easier if rinsed off

immediately instead of after it dries. Always towel dry
the tiller afterwards and apply a light coat of oil or
silicone to prevent rusting or water damage.

IMPORTANT:Never use a "pressure washer" to clean
your tiller. Water can penetrate tight areas of the tiller
and its chain case and cause serious damage to the

unit.

BeltReplacement

Your tiller has been engineered with a belt made of
special material for longer life and better performance.
It should not be replaced with an off-the-shelf belt. See
the retailer from which you purchased your tiller, an
authorized MTD Service Dealer or phone [phone]-

7310 for information regarding price and availability.

Off-SeasonStorage

If the tiller will not be used for a period longer than 30
days, the following steps should be taken to prepare the
tiller for storage.

• Clean the exterior of engine and the entire tiller

thoroughly. Lubricate the tiller as described in the
lubrication instructions.

• We do not recommend the use of pressure

washers to clean your unit. They may cause
damage to spindles, pulleys, bearings or the
engine. The use of pressure washers will result in
shortened life and reduce serviceability.

SECTION7: TROUBLESHOOTING

• Refer to the engine manual for correct engine
storage instructions.

• Wipe tines with oiled rag to prevent rust.

• Store tiller in a clean, dry area. Do not store next to
corrosive materials, such as fertilizer.

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 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 1-
330-220-4683 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.
