SAFETY
Caution should be taken when towing and/or using any
attachment. This attachment combined with the weight distribu-
tion, turning radius, and speed of towing vehicle can result in
severe injury or death to operator, damage to towing vehicle,
and/or attachment if not used properly. Follow all towing safety
precautions noted in the towing vehicle owner’s manual, includ-
ing the following precautions:
• Ensure the combined weight of the towing vehicle (tow vehicle
weight + operator weight) is greater than the maximum towed
weight of attachment (empty attachment weight + weight of load).
• Do not exceed maximum towing capacity of towing vehicle.
• Do not exceed the maximum drawbar pull rating of the towing
vehicle. Drawbar pull is the horizontal force required to pull the
attachment (including weight of load).
• Only tow this product in the vehicle’s tow mode/speed setting or
less than 5 mph. Do not exceed 5 mph.
• Towing speed should always be slow enough to maintain control.
Travel slowly and use caution when traveling over rough terrain.
Avoid holes, rocks and roots.
• Slow down before you turn and do not turn sharply.
• Use wide turning angles to ensure the attachment follows the
path of the towing vehicle.
• Do not use attachment on steep slopes. A heavy load could cause
loss of control or overturn attachment and towing vehicle. Addi-
tional weights may need to be added to your vehicle; check with
towing vehicle manufacturer for recommendations.
• Reduce towed weight when operating on slopes.
• Keep all movement on slopes slow and gradual. Do not make
sudden changes in speed, directions, or turning.
• If you start and stop suddenly on hills, you may lose steering con-
trol or the towing vehicle may tip. Do not start or stop suddenly
when going uphill or downhill. Avoid uphill starts.
• Slow down and use extra care on hillsides. Turf conditions can
affect vehicle stability. Use extreme caution while operating near
drop-offs.
• Do not drive close to creeks, ditches and public highways.
• Watch out for trafc when crossing near roadways.
• Use care when loading or unloading the vehicle into a trailer or truck.
• The attachment can obstruct the view to the rear. Use extra care
when operating in reverse.
• When reversing, carefully back-up straight to avoid jackkning.
Do not allow towing vehicle wheels to contact attachment draw
bar. Damage could result.
• Stop on level ground, disengage drives, set the parking brake,
and shut off engine before leaving the operator’s position for any
reason including emptying the attachment.

GENERAL NOTES (Operation), continued PROTECT THOSE AROUND YOU
• Know your towing vehicle controls and how to stop
safely. READ YOUR TOWING VEHICLE OWNER’S
MANUAL before operating.
• Check the towing vehicle brake action before you oper-
ate. Adjust or service brakes as necessary.

towed load. Travel slowly and allow extra time and dis-
tance to stop.
• Use only approved hitches. Tow this attachment only with
a towing vehicle that has a hitch designed for towing. Do
not connect this attachment except at the approved hitch
point.

USE &CARE
SECTION
FREE POSITION
DETHATCHING POSITION
RELEASED POSITION
- Grass should be less than 3” tall for proper tine action.
- When in use, all tines on the dethatcher should deflect back and
“flip” the thatch forward as shown here.
- If the tines seem to drag without flipping forward, the tine tray
is too low and should be raised.
- If all the tines stay in the free position, the tray should be lowered.
- Make adjustments as necessary, up or down, by no more than 1/4”
each time, until proper results are achieved.
TINE ACTION
- The key to years of trouble-free service is to
keep your dethatcher clean and dry.
- Occasionally check all moving parts for free movement and, if
necessary, lubricate with oil.
- Should rust develop, sand lightly and then paint area with enamel.
- Periodically check all fasteners for tightness.

USE AND CARE
SEQUENCE OF TINE ACTION

GRASS HEIGHT
For best results,
grass should be less
than 3” tall. Shorter
grass will improve
tine action.
TINE RECOMMENDED HEIGHT
When in use the tine will engage the thatch and deect to
the rear as the Dethatcher is pulled forward. The spring will
overcome the tension of the embedded thatch, and pull the
thatch upward. If the tines are too low, the tine will not “ip”
forward as desired.
Figures below show the proper sequence of tine action.
Make adjustments as necessary up or down, by no more
than 1/4” each time to achieve the desired result.
SPEED
The best operating speed is 3 mph
or less.
FREQUENCY
Dethatching is not accomplished in a single pass.
It will normally take several passes over the lawn. Al-
ternating the direction by 90 degrees will improve the
dethatching effect.
CAUTION: Avoid injury! Excessive towed load can cause a loss of control on
slopes. Stopping distance increases with speed and weight of towed load. The
total towed weight must not exceed combined weight of towing vehicle, ballast
and operator.
