OPERATION

HOW TO USE YOUR DETHATCHER

RAISING/LOWERING THE DETHATCHER

•  To raise the dethatcher for transport, lift up on the 

front of the dethatcher and secure it with the transport 
hook. Lower the dethatcher by releasing the transport 
hook.

SETTING THE OPERATING POSITION

•  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.

•  Set the sweeper to the desired operating height. (The 

best height is usually with the brushes set about /" 
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.  

•  Start with the tractor in low gear. Vary the forward 

speed to determine the best speed for maximum 
dethatcher performance.

•  Use a crisscross pattern to achieve the most even 

removal of thatch.

•  On slopes, always operate in an up and down 

direction only. 

•  Avoid extremely sharp turns.

•  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.
