AERATION TIPS
Should I water before aerating?
The best aerating condition is a soft and moist ground. If you are unsure of
the ground conditions, as in soil with high clay content, a simple test will
determine whether it is necessary to water before aerating. Using a garden
hand spade or a large screwdriver, you should be able to drive the tool in the
ground 2 to 3 inches with little effort. If you are unable to do so, then
watering the lawn a day before aerating is necessary.
when should I use the removable weights?
Soil conditions will dictate whether extra machine weight is needed for
effective coring action. The
weights are provided to give you added control, and greater tine penetration.
BEFORE YOU START
-
Make sure that engine oil is at engine manufacturer’s recommended level (refer to engine manual). Be sure gear reduction oil is at engine manufacturer’s recommended level. Make sure the machine is level when filling with oil.
-
With the folding handle in its operating position, lock the handle cam lock (Model AR19 only).
-
Rear wheel control handle must be pulled up so rear wheels are all the way down.
-
Insert weights if needed.
-
Be sure handle is properly mounted.
CAUTION: BE SURE CLUTCH CABLE IS ROUTED PROPERLY. -
Test clutch handle to insure clutch releases freely.
-
The engine top speed is preset by the engine manufacturer. Consult the engine manufacturer’s manual for directions to adjust the governor and carburetor if speed is not within correct range.
-
AR25 Honda Engines Only: The throttle cable has been installed by the factory, however throttle spring needs to be connected to throttle/clutch control lever (see Figure 4).
AERATING
-
Start engine and adjust throttle setting to provide a comfortable walking speed and maintain control of the equipment at all times.
-
Adjust depth control knob (see Figure 1 or 2) to desired depth. Coring depth decreases by turning the knob clockwise.
NOTE: by raising the rear wheels all the way up (to obtain maximum coring depth) you will reduce the unit’s stability but increase length of core. -
Push down the rear wheel control handle to lower aerating tines into the ground (rear wheels will rise).
-
Push down on handle bar for better tine penetration and maneuverability (front wheel will rise).
-
Engage clutch control.
-
Adjust engine throttle setting, if needed, for comfortable speed.
-
To stop, release clutch control.
CAUTION: NEVER CROSS HARD OBJECTS OR SURFACES (SIDEWALKS, DRIVEWAYS, STEPPING STONES, ETC.) WITH TINES DOWN.
THROTTLE CABLE ADJUSTMENT. Model AR25 (Honda Engine Only)
-
Start engine and allow it to reach operating temperature.
-
Adjust the throttle cable at the adjuster bracket by turning the adjuster nut. Tightening will increase engine speed, loosening will reduce engine speed.
NOTE: A properly adjusted throttle will slightly increase engine speed as the clutch engages.- If the clutch engages too soon, the engine will stall.
- If the engine speed is too high, the gradual controlled start is lost.
REAR WHEEL ADJUSTMENT
The rear wheel depth/stability control knob (see Figure 6) allows adjustment
for better stability and maneuverability by turning knob clockwise. Adjusting
for depth by turning knob counterclockwise determines the length of the cores
pulled in the following ways:
- The rear wheels can be adjusted to the level you desire so you can control the penetration of the tines to within a fraction of an inch. The length of the cores pulled can be controlled accordingly.
- With the rear wheels adjusted to the full up position, you will obtain maximum tine penetration. Pushing down on the machine’s handlebars will put most of the weight of the machine on the tines. In this configuration, you will pull the longest cores. (Front wheel will rise).
NOTE
Adjusting for greater stability will shorten the length of the cores you
pull. You will gain greater side-to-side stability (see below “Operating on
Hills.” Adjustments for greater stability will also improve maneuverability
during aeration.)
TURNING AND MANEUVERING THE AERATOR
Gradual maneuvering while aerating can be accomplished by simply guiding the
machine. We recommend that you adjust your engine’s speed control to allow for
a comfortable walking speed. This will also help you maintain complete control
while working in tight spaces. Adjusting for more stability (with the rear
wheels lowered, reducing tine penetration) will make turning easier. When
reversing direction or making sharp turns two methods of turning can be used.
Select the safest and most comfortable method for the conditions you face:
- Release clutch control handle, pull up rear wheel control handle, then pivot machine on rear wheels to turn.
- Release clutch control handle, lift handlebar and pivot machine on front wheel.
WARNING
THIS METHOD IS NOT RECOMMENDED WHEN OPERATING ON HILLS (See next section).
OPERATING ON HILLS
WARNING – DO NOT OPERATE ON HILLS EXCEEDING 35% GRADE.
This unit is not designed to be used on steep slopes. Be aware that when
operating on hills the tilt of the aerator will cause the machine’s center of
gravity to shift to the downhill side of the machine. Under these
circumstances you may experience:
- The need to exert a greater effort to steer and maintain the balance of the machine.
- Uneven tine penetration, when operating across a hill. Due to the shifted center of gravity the downhill tines will penetrate to the maximum depth, while uphill tines may not.
WARNING
IN EXTREME SITUATIONS (VERY STEEP HILLS) THE MACHINE MAY BE SO UNBALANCED,
THAT IT MAY PRESENT THE DANGER OF ROLLING OVER.
Maintenance and Service Instructions
- When operating on hills you should consider the following:
- Operate the machine up and down the hills rather than across them.
- Use the rear wheel depth/stability control knob to set the rear wheels for extra stability. This can be a great benefit when you do choose to run the aerator across a hill.
- An added benefit of using the rear wheel depth control when aerating across a hill is that you will improve the consistency of the cores pulled from the uphill tines when compared to those pulled by the downhill tines.
- Removing the downhill weight reduces roll-over risk and maintains consistent core plug length. (See Figure 8)
- Remove remaining weight from downhill side to uphill side after each pass when operating across hills.
WARNING
NEVER DISENGAGE TINES FROM GROUND WHEN TRAVELLING UP OR DOWN HILL. ONLY
DISENGAGE ON FLAT SURFACE. TRANSPORTING THE HUSQVARNA AERATOR
MODEL AR19 and AR25
The removable weights are for side hill stability and tine penetration as
applicable.
CAUTION
DO NOT LIFT AERATORS. With the weights in place, these models are designed
for easy loading and unloading on ramps and trailers. The treaded front wheel
provides increased control during transport. Use engine power to load unit.
CLEANING AND WASHING
Regular cleaning, washing and lubricating will prolong the service of your
machine.
NOTE: Use care with power washers to avoid damage to Warning Decals,
Operator Instruction Labels, Bearings,Chain and Engine. Limit direct spray on
these items. DO NOT EXCEED 1000 PSI WATER PRESSURE FOR CLEANING TWO MINUTE
WARNING Aerators may be tipped on their engine guard for cleaning and access
for no more than 2 minutes. Engine damage may result from gasoline draining
into the crankcase if prolonged. See engine manufacturer operating and
maintenance instructions.
STORAGE
