firmly with two hands, make sure the
tines are not touching any surface.
Press the safety button (A) while
squeezing the On/Off trigger switch (B).
Once the tiller/cultivator is started, you

ASSEMBLY
LOWER HANDLE WITH TILLING HEAD (Fig. 3B)
•Align the notch on the lower handle with the rib on the tilling
head.
•Push the lower handle into the tilling head.
•Align the side cover with the holes on the lower handle
shaft and push the cover into place.
•Secure with the two ST3.9x16 screws.
WARNING: When connecting the tilling head and lower handle
using the two self-tapping screws supplied, make sure the
screws are securely tightened. Screw heads should be re-
cessed below the surface. DO NOT START THE UNIT UNTIL
TILLING HEAD AND LOWER HANDLE ARE SECURELY
CONNECTED.
Once the tilling head and lower handle are securely connected,
do not remove the self-tapping screws or attempt to disassem-
ble for any purpose. The self-tapping screws will lose their ef-
fectiveness of securing the assembly if removed and re-
installed.
STARTING:
WARNING: The tines start rotating immediately after the
tiller/cultivator is switched on. Keep hands and feet away
from the tines.
Use the tiller/cultivator for breaking sod, preparing seed beds, and
for cultivating gardens and flower beds. The tiller/cultivator can
also dig small holes for planting saplings or potted plants.
For breaking sod or deep tilling, allow the tines to pull the tiller/
cultivator forward to the end of your arm’s reach, then firmly pull it
back toward yourself. You will achieve the best results by repeat-
edly allowing it to move forward and pulling it back.
By pulling the tiller/cultivator back towards yourself, the
tines will dig deeper and more aggressively.
CAUTION: To prevent tripping, take extra precautions when mov-
ing backwards and when pulling the tiller/cultivator back toward
yourself.
5
Model TC70020-1

If the tiller/cultivator digs deep enough to stay in one
spot, gently rock it side to side until it starts moving
forward again.
When working on inclines always stand diagonally to
the incline to retain a firm, safe footing. Do not work
on extremely steep slopes.
For preparing seed beds, we recommend using one of
these tilling patterns (Fig. 4)
Tilling Pattern A– Make two passes over area to be
tilled, the second at a right angle to the first.
Tilling Pattern B– Make two passes over area to be
tilled, the second overlapping the first.
Before use, remove any visible stones or other foreign
bodies from the area.
CAUTION: Before moving the tiller/cultivator from one
area to another switch off the motor and wait for the
tines to come to a complete stop. Be careful not to let
the tines touch the ground while moving the tiller/
cultivator. The tines as well as the unit itself may be
damaged even if the motor is switched off.
Clearing foreign objects:
During operation a stone or root could become lodged
in the tines, or tall grass or weeds may become
wrapped around the tine shaft. To clear the tines or tine
shaft release the trigger lever, wait for the tines to come
to a complete stop and unplug the tiller/cultivator.
Dislodge or remove the foreign matter from the tines or
tine shaft.

CHARGING THE BATTERY PACK
When fully charged, the battery can be safety stored in temperatures
down to –4° degrees F for a period of up to four weeks, before
requiring charging. Fully charge battery pack every 90 days.
If over a period of time the battery pack quickly runs down after a full
80 minute charging period, a replacement battery pack is needed.
To prevent permanent damage to the battery, never store in a
discharged condition.
WINTER STORAGE—Fully recharge before storage and then again
every 90 days.
Since the battery will not develop a memory, it does not have to be
fully discharged before recharging.
A small leakage of liquid from the battery cells may occur under
extreme usage, charging or temperature conditions. This does
not indicate a failure. However, if the outer seal is broken and this
leakage gets on your skin.
a. Wash quickly with soap and water.
b. Neutralize with a mild acid such as lemon juice or
vinegar.
c. If the battery liquid gets in your eyes, flush them with
clean water for a minimum of 10 minutes and seek
immediate medical attention.
Charge the battery pack only with Yardworks 20V Chargers.
Allow at least 80 minutes of charge time before initial use of the
tiller / cultivator.
Make sure the power supply is normal household voltage,
120volts, 60Hz, AC only.
The battery charger should be operated in temperatures between
39 and 104 degrees F.
The battery should be charged in a cool, dry place.
Two to three initial charging/discharging cycles may be required to
achieve maximum run time/capacity.
Do not attempt to open the charger or the unit. There are no
customer serviceable parts inside. Call the customer service help
line at 1-800-633-1501 for assistance.
DO NOT incinerate battery packs even if they are severely
damaged or completely worn out. They can explode in a fire
causing injury.
Use the battery charger indoors only.
Disconnect charger from the power supply when not in use to
prevent damage to the charger during a power surge.

dampened with a mild soap and water mixture.
Never use a water hose to clean the tiller! To remove
soil and debris from the tines, use a stiff brush or a
dampened cloth. Clean the vents on the motor housing
and remove any remaining grass or dirt. Once cleaned,
wipe the tines dry and apply a light coat of oil to prevent
rust.
WARNING: Injury can occur while working on the tines.
Wear protective gloves.
Tines maintenance: Worn tines invite poor performance
and overload of the motor. Check tines before each use.

install tines in the same sequence as shown in Fig 5.
Position the hub so that the larger diameter whole is facing
outward. Make sure the two tines on the same hub are
installed symmetrically with the end of the tine blades
facing downward (Fig. 6).
2. Install the tines with hub onto the shaft. Ensure the larger
diameter whole of the hub is facing outward. The left and
right tine assemblies must be installed symmetrically
(Fig. 6)
3. Install the end caps.
