ASSEMBLY (ALL MODELS)

1. Assemble seven spring tines to the top of the frame tube. Use a 5/16" x 1-1/2" hex bolt, two 3/8" flat washers and a 5/16" nylock nut for each spring tine.

Place one 3/8" flat washer on top of the frame tube and the second 3/8" flat washer on top of the spring tine. See figure 1.

NOTE: On sweepers smaller than 42", use only five spring tines.

2. Assemble a vinyl cap onto each end of the frame tube. See figure 1.

ASSEMBLY (NON-SMARTSWEEP MODELS)

1. Assemble a conduit clamp onto each end of the sweeper height adjustment tube so that the straight part of the clamp is on top of the tube. See figure 3.

2. Remove the hitch brackets and the bolts, if present, from the ends of the sweeper's hitch tubes. Slide the transport hook onto the L.H. hitch tube as shown in figure 3.

3. Reassemble the hitch brackets and bolts to the hitch tubes. Refer to your sweeper owner's manual.

4. Insert the bolt through the welded bracket and assemble a 1/2" nylock jam nut onto the bolt. Adjust nuts so that there is no end play in the wheel and then tighten securely against the welded bracket.

Make sure the wheel still turns freely. See figure 2.

8. Center the dethatcher with the sweeper.

9. Assemble the keeper brackets (bend to the inside) to the sweeper's hitch tube, outside of the conduit clamps. Use a u-bolt and two 1/4" nylock nuts per bracket. Position the keeper brackets against the sides of the conduit clamps, approximately perpendicular to the ground. Tighten the nylock nuts without bending the keeper brackets. See figure 5.

OPERATION

RAISING/LOWERING THE DETHATCHER

1. To raise the dethatcher for transport, lift up on the front of the dethatcher and secure it with the transport or SMARTSweep hook. Lower the dethatcher by releasing the hook.

SETTING THE OPERATING POSITION

1. The operating height of the dethatcher is controlled by the gauge wheel at the front of the dethatcher and is not adjustable. The correct wheel position was determined in figure 2 when you assembled the wheel.

2. Set the sweeper to the desired operating height. (The best height is usually with the brushes set about 1/2" down into the grass.) Refer to your sweeper owner's manual for sweeper.

USING THE DETHATCHER

Regular removal of thatch is critical to the maintenance of a healthy lawn. Thatch is layer of stems, clippings, runners, roots and leaves that have not decayed. Excessive thatch prevents air, water and fertilizer from reaching the roots.

The dethatcher will effectively dislodge excessive thatch from your lawn.

1. Start with the tractor in low gear. Vary the forward speed to determine the best speed for maximum dethatcher performance.

2. Use a crisscross pattern to achieve the most even removal of thatch.

3. On slopes, always operate in an up and down direction only.

4. Avoid extremely sharp turns.

5. Avoid towing the dethatcher across sudden steep dips in the ground while dethatching. Loss of ground contact with the gauge wheel could cause the dethatcher to be pulled back underneath the sweeper.

MAINTENANCE

1. Before each use, check all nuts and bolts for tightness.

2. Clean after each use to help prevent rust.

3. If rust appears on the spring tines, sand lightly and coat with enamel paint.

STORAGE

1. Always store in a dry area, and coat exposed metal with light oil when not in use.
