PARTS BREAKDOWN

The Border-Edger Kit is a useful tool for making clean cuts in

the lawn along the borders of gardens, ower beds, walkways,

and driveways for a well manicured look. To install the Border-

Edger Kit, do the following:

INSTALLATION

1. Make sure the cultivator is not running by flipping the ON/

OFF switch to the OFF position.

2. Remove the hairpins from both sides of the tine shaft.

3. Remove the cultivating tines from the shaft, remembering

which direction they are facing.

4. Put the tines in a safe place and save the (2) hairpins, they will

be used on the Border-Edger Kit.

5. Slide the border-edger tine onto either side of the tine

shaft. Make sure that the hub collar of the border-edger tine

faces outward, away from the transmission of the cultivator.

SEE FIGURE 11

6. Take the (2) hairpins saved in Step 4 and insert them through

the inner and outer holes in the tine shaft on each side of the

border-edger tine to secure the tine blade in place on the

shaft. SEE FIGURE 11

7. Slide the border-edger wheel onto the opposite side of the

tine shaft as far as it will go.

8. Insert the remaining (1) hairpin, that came with the kit,

through the inner hole next to the wheel in the middle of the

tine shaft. SEE FIGURE 11

9. Before using the Border-Edger Kit, remove the drag stake from

the unit.

10.Set the cultivator wheels to the HIGHEST (top) position.

CAUTION

BE AWARE THAT THE CULTIVATOR COULD

UNEXPECTEDLY BOUNCE UPWARD, OR JUMP

FORWARD IF THE TINES STRIKE CONCRETE,

PAVEMENT, OR OTHER HARD SURFACES OR HARD

OBSTACLES BURIED UNDER GROUND.

The Dethatcher Kit is very effective for lifting away the excessive matted layers of thatch that can prevent moisture, oxygen and

nutrients from penetrating the soil and can harbor disease and insects. Use in Spring, Summer, and Fall to bring life and color back

to your lawn.

1. Flip the ON/OFF switch to the OFF position. Remove the cultivating tines and the drag stake (SEE PAGE 12).

2. Unscrew mount bolts/nuts that connect the wheel bracket to the drag stake mount and set wheel bracket aside. SEE FIGURE 13

3. Slide dethatcher shield over the unit’s tine shield from the rear of the unit and secure using bolts (176) and nuts (400020).

SEE FIGURE 12

3. Secure the lower part of the dethatcher shield to the drag stake mount using the detent pin (46145).

4. Install wheel extension plate (4676) using additional bolts (46142) and nuts (4650). Make sure wheel extension is facing the right

direction. (The side, with the two holes flush to the edge, connects to the drag stake mount) SEE FIGURE 13

a. With the mount bolts/nuts attach the wheel extension to the drag stake mount.

b. Then with the bracket bolts/nuts (included with the Dethatcher Kit) attach the wheel bracket to the wheel extension.

5. Slide the Left and Right Dethatcher Assemblies onto the tine shaft making sure the Right Assembly is installed on the right side

and Left Assembly is installed on the left side as defined from the user’s position. SEE FIGURE 14

6. Secure dethatcher assemblies using the hairpins (4652). The hairpins go through the inner holes of the tine shaft.

NOTE: The drag stake should not be used when using the dethatcher kit.
