footwear; and hearing protection. T ie back long

hair , secure loose clothing, and do not wear loose

jewelry .

• Do not operate the machine when tired, ill, or

under the inuence of alcohol or drugs.

• Keep bystanders, children, and pets out of

the operating area. Do not allow children to

operate the machine. Allow only people who are

responsible, trained, familiar with the instructions,

and physically capable to operate the machine.

• Never carry passengers on the machine.

• Operate the machine only in good visibility to avoid

holes or hidden hazards.

• Keep your hands and feet away from the tines.

• Look behind and down before backing up to be

sure of a clear path.

• Stop the machine, shut of f the engine, remove

the key , wait for all moving parts to stop, and

inspect the tines after striking an object or if there

is an abnormal vibration in the machine. Make all

necessary repairs before resuming operation.

• Always maintain proper tire pressure.

• Reduce traction speed on rough roads and

surfaces.

Slope Safety

• Slopes are a major factor related to loss of control

and rollover accidents, which can result in severe

injury or death. Y ou are responsible for safe slope

operation. Operating the machine on any slope

requires extra caution.

• Evaluate the site conditions to determine if the

slope is safe for machine operation, including

surveying the site. Always use common sense

and good judgment when performing this survey .

• Review the slope instructions listed below for

operating the machine on slopes and review the

conditions to determine whether you can operate

the machine in the conditions on that day and at

that site. Changes in the terrain can result in a

change in slope operation for the machine.

• A void starting, stopping, or turning the machine on

slopes. A void making sudden changes in speed or

direction. Make turns slowly and gradually .

• Do not operate a machine under any conditions

where traction, steering, or stability is in question.

• Remove or mark obstructions such as ditches,

holes, ruts, bumps, rocks, or other hidden hazards.

T all grass can hide obstructions. Uneven terrain

could overturn the machine.

• Be aware that operating the machine on wet

grass, across slopes, or downhill may cause the

machine to lose traction. Loss of traction to the

drive wheels may result in sliding and a loss of

braking and steering.

• Use extreme caution when operating the machine

near drop-of fs, ditches, embankments, water

hazards, or other hazards. The machine could

suddenly roll over if a wheel goes over the edge

or the edge caves in. Establish a safety area

between the machine and any hazard.

Using Aerator Statistics for

Estimating T opdressing

The machine uses 2 counters to log the area

aerated and the displaced soil-core volume. Use

the information from these counters to estimate the

amount of top dressing to apply to the aerated turf

area(s).

• The Area 1 counter is not PIN code protected, and

is intended to be reset by the machine operator .

Note: If the operator records the Area 1 counter

for each aeration site, you can estimate the

amount of topsoil and delivery requirements for

each site.

• The Area 2 counter is PIN code protected, and

is intended to be reset by the supervisor or their

delegate.

• The area aerated displays in m

(SI) or ft

(English)

units of measure.

• The displaced-coring volume displays as m

(SI)

or yd

(English) units of measure.

• When viewing the displaced-coring volume

counters, the machine calculates the volume using

the tine diameter and the tine quantity that you

entered in the InfoCenter .

Important: If the tine diameter and/or the

tine quantity value(s) are incorrect before

aerating the site, the InfoCenter will calculate

and display incorrect core volume values for

Area 1 and Area 2. If the diameter and/or

quantity values are changed after aerating, the

InfoCenter will change the displayed volume

values.

Operating T ips

General

• Make very gradual turns when aerating. Never

make sharp turns with the coring head engaged.

Plan your aeration path before lowering the

aerator .

• Always maintain awareness of what lies ahead in

the direction of forward travel. A void aeration next

to buildings, fences, and other equipment.

• Look behind frequently to ensure that the machine

operates properly , and you maintain alignment

with previous pass.

• Always clear the area of all damaged machine

parts, such as broken tines, etc., to prevent

their being picked up by mowers or other turf

maintenance equipment.

• Replace broken tines and inspect and correct

damage to those still usable. Repair any other

machine damage before commencing operation.

• When aerating with less than the full width of

the machine, you may remove tines, but the tine

heads should remain installed on the stomper

arms to ensure proper balance and operation of

the machine.

• This machine aerates deeper than most greens

aerators. On native or modied push-up greens

and tees, the deeper depth and longer hollow tines

may have dif culty ejecting the complete core.

This is due to harder native soil that sticks in the

end of the tine. Side-eject greens/tees tines from

the manufacturer stay cleaner and reduce the time

required to clean the tines out. Y ou will eventually

eliminate this condition with continued aeration

and top-dressing programs.

• This machine is designed to provide as much depth

as possible; However , in some turf conditions the

turf guards and/or turf guard bolts could cause

damage when aerating at the full depth setting.

If aerating at the maximum allowable depth (with

any length tine) after running the ground-height

calibration, the turf-guard bolts drag or contact the

turf, reduce the depth by a step (1/4 inch).

Hard Ground

If the ground is too rm to obtain the desired coring

depth, the coring head can get into a bouncing rhythm.

This is due to the hard pan the tines are attempting to

penetrate. Correct this condition by attempting the

following:

• Do not aerate if ground is too hard or dry . Y ou

obtain best aeration results after a rain or watering

the turf the previous day .

• Change to a 3-tine head, if attempting to use the

4-tine head or reduce the number of tines per

stomper arm. Attempt to maintain a symmetrical

tine conguration to evenly load the stomper arms.

• If ground is hard packed, reduce aerator

penetration (depth setting), clean up the cores,

water the turf, and re-aerate at a deeper

penetration.

Aeration of soil types built on top of hard subsoils (i.e.,

soil/sand placed over rocky soil) can cause undesired

hole quality . This occurs when the aeration depth is

greater than the built up soil and the subsoil is too

hard to penetrate. When the tines contact this harder

subsoil, the aerator may lift and cause the top of the

holes to become elongated. Reduce the aerating

depth suf ciently to avoid penetration into the hard

subsoil.

Entrance Hole Quality

The entrance hole quality is deteriorating when the

hole is slotted (pulled forward).

If the hole entrance quality is deteriorating, check the

tine ground-height calibration, refer to Checking the

T ine Ground-Height Calibration ( page 51 ) .

Mini T ine (Quad T ine)

Because of the double row design, the mini-tine coring

head requires the hole spacing to be set at 6.3 cm

(2-1/2 inches). Ground speed is critical to maintain

the appearance of 3.2 cm (1-1/4 inches) hole spacing.

Refer to Setting the Hole Spacing ( page 34 ) if your

hole spacing requires a small change.

With the mini tine head or larger solid tine use, the turf

root structure is important to preventing turf damage

due to tearing of the root zone. If the center 2 arms

begin to lift the turf or damage to the root zone is

excessive, proceed as follows:

• Increase the hole spacing

• Decrease tine size

• Decrease tine depth

• Remove some of the tines

The lifting action that solid a tine creates when it pulls

from the turf may cause turf damage. This lift can

tear the root zone if the density of tines or diameter

of tines is too high.

Front Hole Dimple or Push During

the Aeration Pass (Solid T ines or

Softer Soil Conditions)

When aerating with longer solid tines (i.e., 3/8 x 4

inches long) or needle type tines, the front of the holes

may become slotted or tufted. T o regain excellent

hole quality for this conguration, try the following:

• Calibrate the tine ground height; refer to Calibrating

the T ine Ground Height ( page 35 ) .

• Slow the engine high idle speed down to 2800 to

2900 rpm.

Note: Because traction and coring head speeds

increase and decrease together with engine

speed, hole spacing is not af fected.

If slowing the engine speed does improve hole quality

for the longer solid or needle type tines, adjust the

roto-link damper .

Note: Under most conditions, the factory setting

works best.

• If the front of the holes is slotted or tufted, a

stif fer roto-link setting helps resist hole-push and

improve hole quality .

• If the back of the holes is slotted or tufted, a softer

roto-link setting helps improve the hole quality .

Note: Y ou must reverse the position of the roto-Link

damper if you change back to a coring style tine or

any of the mini-tines.

Lubrication

Checking the Coring Head

Bearings

Service Interval : Y early —Check the coring head

bearings.

Every 500 hours —Inspect the coring head

bearings, if needed, replace.

The machine has no grease ttings that must be

lubricated.

Important: Bearings rarely fail from defects in

materials or workmanship. The most common

reason for failure is moisture and contamination

working its way past the protective seals.

Bearings that are greased rely upon regular

maintenance to purge harmful debris from the

bearing area. Sealed bearings rely on an initial

ll of special grease and a robust integral seal to

keep contaminants and moisture out of the rolling

elements.

The sealed bearings require no lubrication or short

term maintenance. This minimizes routine service

required and reduces the potential of turf damage

due to grease contamination. These sealed bearing

packages provide good performance and life under

normal use, but periodic inspections of bearing

condition and seal integrity should be conducted to

avoid downtime. Inspect the bearings seasonally

and replace them if they are damaged or worn.

Bearings should operate smoothly with no detrimental

characteristics such as high heat, noise, looseness,

or rust weeping.

Due to the operating conditions these bearing/seal

packages are subject to (e.g., sand, turf chemicals,

water , impacts, etc.) they are considered normal wear

items. Bearings that fail due to causes other than

defects in materials or workmanship are typically not

covered under warranty .

Note: Y ou can negatively af fect bearing by using

improper wash down procedures. Do not wash down

the machine when it is still hot and avoid directing

high-pressure or high volume spray at the bearings.

It is common for new bearings to purge some grease

out the seals on a new machine. This purged grease

turns black in color due to collection of debris and not

due to excessive heat. It is good practice to wipe this

excess grease from the seals after the initial 8 hours.

There may always appear to be a wet area around

the seal lip. This is not detrimental to bearing life, and

keeps the seal lip lubricated.

California Proposition 65 W arning Information

What is this warning?

Y ou may see a product for sale that has a warning label like the following:

W ARNING: Cancer and Reproductive Harm—www .p65W arnings.ca.gov .

What is Prop 65?

Prop 65 applies to any company operating in California, selling products in California, or manufacturing products that may be sold in or brought into

California. It mandates that the Governor of California maintain and publish a list of chemicals known to cause cancer , birth defects, and/or other

reproductive harm. The list, which is updated annually , includes hundreds of chemicals found in many everyday items. The purpose of Prop 65 is to

inform the public about exposure to these chemicals.

Prop 65 does not ban the sale of products containing these chemicals but instead requires warnings on any product, product packaging, or literature with

the product. Moreover , a Prop 65 warning does not mean that a product is in violation of any product safety standards or requirements. In fact, the

California government has claried that a Prop 65 warning “is not the same as a regulatory decision that a product is ‘safe’ or ‘unsafe.’” Many of these

chemicals have been used in everyday products for years without documented harm. For more information, go to https://oag.ca.gov/prop65/faqs-view-all .

A Prop 65 warning means that a company has either (1) evaluated the exposure and has concluded that it exceeds the “no signicant risk level”; or (2)

has chosen to provide a warning based on its understanding about the presence of a listed chemical without attempting to evaluate the exposure.

Does this law apply everywhere?

Prop 65 warnings are required under California law only . These warnings are seen throughout California in a wide range of settings, including but not

limited to restaurants, grocery stores, hotels, schools, and hospitals, and on a wide variety of products. Additionally , some online and mail order

retailers provide Prop 65 warnings on their websites or in catalogs.

How do the California warnings compare to federal limits?

Prop 65 standards are often more stringent than federal and international standards. There are various substances that require a Prop 65 warning

at levels that are far lower than federal action limits. For example, the Prop 65 standard for warnings for lead is 0.5 μg/day , which is well below

the federal and international standards.

Why don’t all similar products carry the warning?

• Products sold in California require Prop 65 labelling while similar products sold elsewhere do not.

• A company involved in a Prop 65 lawsuit reaching a settlement may be required to use Prop 65 warnings for its products, but other companies

making similar products may have no such requirement.

• The enforcement of Prop 65 is inconsistent.

• Companies may elect not to provide warnings because they conclude that they are not required to do so under Prop 65; a lack of warnings for a

product does not mean that the product is free of listed chemicals at similar levels.

Why does T oro include this warning?

T oro has chosen to provide consumers with as much information as possible so that they can make informed decisions about the products they buy and

use. T oro provides warnings in certain cases based on its knowledge of the presence of one or more listed chemicals without evaluating the level of

exposure, as not all the listed chemicals provide exposure limit requirements. While the exposure from T oro products may be negligible or well within the

“no signicant risk” range, out of an abundance of caution, T oro has elected to provide the Prop 65 warnings. Moreover , if T oro does not provide these

warnings, it could be sued by the State of California or by private parties seeking to enforce Prop 65 and subject to substantial penalties.
