OPERATION  
Regular removal of thatch is critical to maintenance of a  
OPERATING TIPS  
healthy lawn. Excessive thatch prevents air, water and  
fertilizer from reaching the roots. To effectively dislodge  
excessive thatch from your lawn, read these instructions  
for proper adjustment and operation of the dethatcher.  
Vary the vehicle's forward speed until the best  
dethatching action is achieved.  
For best results, use a crisscross pattern on your  
lawn.  
ADJUSTMENT OF TINE SHIELD  
Move the towing vehicle onto a level surface, such  
as a driveway or garage floor and attach the tine  
dethatcher to the vehicle hitch. See figure 7.  
If the dethatcher appears to be "jumping" during  
use, then extra weight should be added to the tine  
shield. In most conditions extra weight will be needed.  
Concrete patio blocks are recommended for weight  
because of their low profile; however any type of  
weight is suitable if it can be tied down to the shield.  
Secure weight by using suitable binding material such  
as rubber tie down straps or wire, fastening to the  
holes in the shield flange. See figure 8.  
Lower the dethatcher into operating position using the  
lift handle. Loosen the two nylock nuts and carriage  
bolts which fasten the hitch mount arms to the hitch  
arm mount brackets at the rear of the tine shield.  
Adjust the tine shield until it is level and both the front  
and rear spring tines are in contact with the ground.  
Retighten the hex nuts. See figure 7.
