OPERATING TIPS

De-thatching is recommended for early spring, late fall and

prior to fertilizing. It is not recommended to de-thatch with

every mowing of the lawn. The tine dethatcher can be easily

removed for storage (Maintenance/Storage).

• Always start with transmission in rst (low) gear and

gradually increase speed as conditions permit.

• Do not attempt to use dethatcher in eld mowing.

• For best results, use a "criss-cross" pattern on your lawn.

• Vary vehicle speed to determine best speed.

• The front and rear tines should be kept level.

• Stop vehicle and lift dethatcher to transport position

when making sharp turns.

OPERATION / SERVICE / ADJUSTMENTS

Leveling the dethatcher

• Move tractor with front mounted dethatcher onto a level

surface, such as a drive or garage oor.

• Lower dethatcher from transport position to rest on

level surface.

• Loosen carriage bolts through mounting arms and

angle brackets. (Refer to gure 3 on page 5.)

• Adjust tine shield until spring tines come in contact with

level surface, keeping front and back tines at same

height. Tighten mounting arm carriage bolts on top of

dethatcher shield to lock adjustment. See gure 20.

• If you need more adjustment, try moving the axle

bushing up or down between the mounting arms. Be

sure to retighten the bolts securing the bushing. See

gure 20.

• To replace a spring tine:

a. Use a screw driver to pry the tabs up off of the

spring tine.

b. Remove old the spring tine from the tray.
