AERATION TIPS
Should I water before aerating?
Best aerating condition is a soft and moist ground. If you are unsure of the ground conditions such as in a soil with a high clay
content, a simple test will determine whether it is necessary to water before aerating. Using a garden hand spade or a large
screw driver, 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
1. Make sure that engine oil is at engine manufacturers recommended level (refer to engine manual). Be sure gear
reduction oil is at engine manufacturers level.
With the folding handle in its operating position, lock the handle cam lock (Model 244 only).
Rear wheel control handle must be pulled up so rear wheels are all the way down.
If weights are needed, insert and lock in place.
Kan SD
Be sure handle 1s properly mounted.
i CAUTION: Be sure clutch cable is routed properly.
6. Test clutch handle to insure clutch spring releases freely.
7. The engine top speed 15 preset by the engine manufacturer. Consult the engine manufacturers manual for directions to
adjust the governor and carburetor if speed is not within correct range.
AERATING
1. Start engine and adjust throttle setting to provide a comfortable walking speed and maintain control of the equipment at
all times.
2. Adjust depth control knob (see figure 1 or 2) to desired depth. Coring depth decreases by turning the knob clockwise.
Note that 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.
AID ABD
Zk] CAUTION: Never cross hard objects or surfaces (sidewalks, driveways, stepping stones, etc.)
with tines down.

Operating Instructions (continued)
REAR WHEEL ADJUSTMENT
The rear wheel Depth/Stability Control Knob (see figure 6) allows adjustment for more stability
(and maneuverability) by turning knob clockwise. Adjusting for more depth by turning knob
counter-clockwise determines the length of the cores pulled in the following ways:
(A) 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. |
(B) With the rear wheels adjusted to the full up position, you will obtain maximum tine
penetration. Pushing down on the machine's handle bars will put all the weight of the
machine on the tines. In this configuration you will pull the longest cores. (Front wheel Figure 6
will rise). | | Depth/Stability Control Knob
NOTE: Adjusting for more 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: |
(A) Release clutch control handle, pull up rear wheel control handle, then pivot machine on rear wheels to turn.
(B) Release clutch control handle, lift handle bar and pivot machine on front wheel.
Warning: This method is not recommended when operating on hills. {See next section).
g Р g
OPERATING ON HILLS
à 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:
(A) The need to exert a greater effort to steer and maintain the balance of the machine.
(B) 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. Do not operate on steep Figure 7
slopes. 31° Grade
When operating on hills, you may consider the following:
(A) Operate the machine up and down the hills rather than across them.
(B) 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.
(C) Removing the downhill weight to reduce roll-over risk and maintain consistent core
plugs length (on 442 only). See Figure 8.
(D)Remove remaining weight from downhill side to uphill side after each pass when Figure 8
operating across hills. Remove Downhill Weight
WARNING: Never disengage tines from ground when travelling up or down hill.
Only disengage on flat surface.

Free-Wheeling Tine Assembly Removal and Replacement - Model 442 Only
Complete steps 1 through 12 in previous section, then proceed with the following:
1.
2.
3.
8.
After the bearing is off the rotor, unlock the inner bearing that holds on the tine assembly.
Remove outer free-wheeling tine assembly.
Place the new rotor assembly beside the old assembly so that you have a pattern to follow which provides the correct
direction which the new tines are to be installed. You can also refer to the tines on the fixed tine assembly as an example
of proper assembly.
. Once the tines are installed on the free-wheeling assembly, re-install the inner and outer bearing assemblies on the free-
wheeling assembly with the bearing hubs facing toward the fixed tines making sure that the inner bearing has a locking
collar. Hand tighten the nuts only.
Slide the new free-wheeling tine assembly on the shaft making sure that the tine direction matches the direction of the
fixed tine assembly, the bearing with the locking collar faces the fixed tines and butts up against the shoulder of the
shaft.
Tighten the four nuts for the bearing assemblies.
Lock the bearing collar in place with the hammer and punch making sure the collar locks in the same direction as the
rotation of the fixed tines.
Replace outer shaft bearing and re-install the entire rotor assembly by reversing steps 1 through 12.
Instructions are for one side. Both are identical procedurally.

A One-Year Limited Warranty
(A Two-Year Full Warranty for Residential Use)
What is Covered By This Express Warranty?
The Toro Company promises to repair any TORO product used for
commercial, institutional, or rental purposes if defective in materials or
workmanship for a period of one year from the date of purchase. The
cost of parts and labor are included, but the customer pays the
transportation cost. Transportation within a 15-mile radius of a TORO
ProLine Service Dealer is covered under this warranty for Riding
Products, Mid-size Mowers and Turf Maintenance Equipment.
What Products Are Covered By This Warranty?
The following products and their attachments are covered by this
warranty:
+ Z-Master Zero Radius Tractors
+ ProLine Mid-size Mowers
* Groundsmaster Riding Mowers
+ ProLine Hand-held Gas Products
Backpack Blowers
* Commercial WPM
* Turf Maintenance Equipment
+ Debris Management Equipment
How About Residential Use?
TORO products used for residential use are covered by a full two-year
warranty.
How Do You Get Warranty Service?
Should you feel your TORO product contains a defect in materials or
workmanship, contact the dealer who sold you the product or any
TORO ProLine Service Dealer. The Yellow Pages of your telephone
directory is a good reference source; look under TORO Commercial
Service Dealers. The Service Dealer will either arrange service at his/her
dealership or recommend another authorized Service Dealer who may
be more convenient. You may need proof of purchase (copy of
registration card, sales receipt, etc.) for warranty validation.
If for any reason you are dissatisfied with a Service Dealer's analysis of
the defect in materials or workmanship or if you need a referral to a
TORO ProLine Service Dealer, please feel free to contact us at the
following address:
Toro Customer Service Department
8111 Lyndale Avenue South
Bloomington, MN 55420-1196
612-888-8801 or 800-348-2424
What Must You Do To Keep The Warranty In Effect?
You must maintain your TORO Product by following the maintenance
procedures described in the operator’s manual. Such routine
maintenance, whether performed by a dealer or by you, is at your own
expense.
What Does This Warranty Not Cover?
and
How Does Your State Law Relate To This Warranty?
There is no other express warranty except as described above. This
express warranty does not cover:
+ Cost of regular maintenance service or parts, such as filters, fuel,
lubricants, tune-up parts, blade sharpening, brake and clutch
adjustments.
* Any product or part which has been altered or misused or
required replacement or repair due to normal wear, accidents, or
lack of proper maintenance.
* Repairs necessary due to improper fuel, contaminants in the fuel
system, or failure to properly prepare the fuel system prior to any
period of non-use over three months.
* Pickup and delivery charges for distances beyond a 15-mile radius
from a TORO ProLine Service Dealer.
All repairs covered by this warranty must be performed by a TORO
Service Dealer using Toro approved replacement parts.
The Toro Company is not liable for indirect or consequential
damages in connection with the use of the TORO Products covered
by this warranty, including any cost or expense of providing
substitute equipment or service during reasonable periods of
malfunction or non-use pending completion of repairs under this
warranty. Some states do not allow exclusions of incidental or
consequential damages, so the above exclusion may not apply to you.
This warranty gives you specific legal rights, and you may also have
other rights which vary from state to state.
Countries other than the United States or Canada
Customers who have purchased TORO products exported from the
United States or Canada should contact their TORO Distributor
(Dealer) to obtain guarantee policies for your country, province, or
state. If for any reason you are dissatisfied with your Distributor’s
service or have difficulty obtaining guarantee information, contact
the TORO importer. If all other remedies fail, you may contact us at
