Safety

Training

1. Read the instructions carefully. Be familiar with

the controls and the proper use of the equipment.

2. Never allow children or people unfamiliar with

these instructions to use the lawn mower. Local regulations may restrict the age of the operator.

3. Never mow while people, especially children, or

pets are nearby.

4. Keep in mind that the operator or user is responsi-

ble for accidents or hazards occurring to other people or their property.

5. Do not carry passengers.

6. All drivers should seek and obtain professional and

practical instruction. Such instruction should emphasize:

2. Thoroughly inspect the area where the equipment is

to be used and remove all objects which may be thrown by the machine.

3. WARNING—Petrol is highly flammable.

• Store fuel in containers specifically designed for this purpose.

• Refuel outdoors only and do not smoke while refueling.

• Add fuel before starting the engine. Never remove the cap of the fuel tank or add petrol while the engine is running or when the engine is hot.

• If petrol is spilled, do not attempt to start the engine but move the machine away from the are of spillage and avoid creating any source of ignition until petrol vapors have dissipated.

• Replace all fuel tanks and container caps securely.

• the need for care and concentration when working with ride-on machines;

• control of a ride-on machine sliding on a slope will not be regained by the application of the brake. The main reasons for loss of control are:

– insufficient wheel grip; – being driven too fast; – inadequate braking; – the type of machine is unsuitable for its

task;

– lack of awareness of the effects of ground

conditions, especially slopes;

– incorrect hitching and load distribution.

Preparation

1. While mowing, always wear substantial footwear

and long trousers. Do not operate the equipment when barefoot or wearing open sandals.

4. Replace faulty silencers.

Operation

1. Do not operate the engine in a confined space where

dangerous carbon monoxide fumes can collect.

2. Mow only in daylight or in good artificial light.

3. Before attempting to start the engine, disengage all

blade attachment clutches and shift into neutral.

4. Do not use on slopes of more than:

• Never mow side hills over 5°

• Never mow uphill over 10°

• Never mow downhill over 15°

5. Remember there is no such thing as a “safe” slope.

Travel on grass slopes requires particular care. To guard against overturning:

• do not stop or start suddenly when going up or downhill;

Page 4

• engage the clutch slowly, and always keep the machine in gear, especially when travailing downhill;

• machine speeds should be kept low on slopes and during tight turns;

• stay alert for bumps and hollows and other hidden hazards;

• never mow across the face of the slope, unless the lawn mower is designed for this purpose.

6. Use care when pulling loads or using heavy equip-

ment.

• Use only approved drawbar hitch points.

• Limit loads to those you can safely control.

14. Stop the engine and disengage the drive to the attach-

ment

• before refueling;

• before removing the grass catcher;

• before making height adjustments unless the adjustment can be made from the operator’s position.

• before clearing blockages;

• before checking, cleaning or working on the lawnmower;

• after striking a foreign object. Inspect the lawnmower for damage and make repairs before restarting and operating the equipment.

• Do not turn sharply. Use care when reversing.

• Use counterweight(s) or wheel weights when suggested in the instruction handbook.

7. Watch out for traffic when crossing or near road-

ways.

8. Stop the blades rotating before crossing surfaces

other than grass.

9. When using any attachments, never direct dis-

charge of material toward bystanders nor allow anyone near the machine while in operation .

10. Never operate the lawn mower with defective

guards, shields or without safety protective devices in place.

11. Do not change the engine governor settings or

overspeed the engine. Operating the engine at excessive speeds may increase the hazard of personal injury.

15. Reduce the throttle setting during engine runout and, if

the engine is provided with a shutoff valve, turn the fuel off at the conclusion of mowing.

Maintenance and Storage

1. Keep all nuts, bolts and screws tight to be sure the

equipment is in safe working condition.

2. Never store the equipment with petrol in the tank

inside a building where fumes may reach an open flame or spark.

3. Allow the engine to cool before storing in any enclo-

sure.

4. To reduce the fire hazard, keep the engine, silencer,

battery compartment and petrol storage area free of grass, leaves, or excessive grease.

5. Check the grass catcher frequently for wear or deterio-

ration.

12. Before leaving the operator’s position:

• disengage the power take-off and lower the attachments;

• change into neutral and set the parking brake;

• stop the engine and remove the key.

13. Disengage the drive to attachments when transport-

ing or not in use.

6. Replace worn or damaged parts for safety.

7. If the fuel tank has to be drained, this should be done

outdoors.

8. Be careful during adjustment of the machine to prevent

entrapment of the fingers between moving blades and fixed parts of the machine.

9. On multi-bladed machines, take care as rotating one

Page 5

blade can cause other blades to rotate.

10. When the machine is to be parked, stored or left

unattended, lower the cutting means unless a positive mechanical lock is used.

Before Operating

CHECK THE ENGINE OIL

The engine is shipped with 1.7 liter (with filter) of oil in the crankcase; however, the level of oil must be checked before and after you first start the engine.

1. Position the machine on a level surface.

2. Unscrew the dipstick and wipe it with a clean cloth.

Screw the dipstick into the filler neck and make sure it is seated fully. Unscrew the dipstick and check the oil level. If it is low, add enough oil to raise the level to the FULL mark on the dipstick.

3. The engine uses any high-quality detergent oil having the

American Petroleum Institute —API—service classification SC, SD, SE, SF or SG. Recommended viscosity (weight) is SAE 30.

4. Pour the oil into the filler neck until the oil level is up to

the FULL mark on the dipstick. Add the oil slowly and check the level often during this process. DO NOT OVERFILL.

IMPORTANT: Check the oil level every 8 operating hours or daily. Initially change the oil after the first 8 hours of operation; after that—under normal conditions—change the oil after every 50 hours and the filter after every 100 hours. However, change the oil more often when you operate the engine in extremely dusty or dirty conditions.

5. Install the dipstick firmly in place.

FILLING THE GAS T ANK

THE TORO COMPANY STRONGLY RECOMMENDS THE USE OF CLEAN, FRESH UNLEADED REGULAR GASOLINE IN TORO GASOLINE-POWERED PRODUCTS. UNLEADED GASOLINE BURNS CLEANER, EXTENDS ENGINE LIFE, AND PROMOTES GOOD STARTING BY REDUCING THE BUILD-UP OF COMBUSTION CHAMBER DEPOSITS. LEADED GASOLINE CAN BE USED IF UNLEADED IS NOT AVAILABLE.

Figure 1

1. Dipstick

NOTE: Never use methanol, gasoline containing methanol, gasohol containing more than 10% ethanol, gasoline additives,

Page 11

premium gasoline, or white gas because the engine fuel system damage could result.

1. Fill the gasoline tank to the bottom of the filler neck. DO

NOT OVERFILL. Install the cap and tighten it securely in place.

DANGER

Because gasoline is flammable, use caution when storing or handling lt. Do not fill the fuel tank while the engine is running, or hot, or when the machine is in an enclosed area. Vapors may build up and be ignited by a spark or flame source many feet away. DO NOT SMOKE while filling the fuel tank to prevent the possibility of an explosion. Always fill the fuel tank outside and wipe up any spilled gasoline before starting the engine. Use a funnel or spout to prevent spilling gasoline before starting the engine and fill the tank to about 1 inch from the top of the tank, not the filler neck. Store gasoline in a clean safety-approved container and keep the cap in place on the container. Keep gasoline in a cool, well-ventilated place—never in an enclosed area such as a hot storage shed. To assure volatility, do not buy more than a 30-day supply of gasoline. Gasoline is a fuel for internal combustion engines; therefore, do not use it for any other purpose. Since many children like the smell of gas, keep it out of their reach because the fumes are explosive and dangerous to inhale.

CHECK THE HYDRAULIC SYSTEM

The hydraulic system is designed to operate on Mobil DTE 26 or equivalent anti-wear hydraulic fluid. The machine’s large hydraulic oil tank and smaller auxiliary oil tank are filled at the factory with 32 liters of fluid. However, check the level of hydraulic fluid before first starting the engine and daily thereafter.

Hydraulic Oil (Recommended brands):

Mobil DTE 26 Shell Tellus 68 Amoco Rykon Oil #68 Conoco Super Hydraulic Oil 68 Exxon Nuto 68

Page 12

Kendall Kenoil R&O AW 68 Pennzoil Penreco 68 Phillips Magnus A 68 Standard Energol HLP 68 Sun Sunvis 831 WR Union Unax AW 68 Chevron AW Hydraulic Oil 68

NOTE: All are interchangeable.

IMPORTANT. Use only the hydraulic oils specified. Other fluids could cause system damage.

NOTE: A red dye additive for the hydraulic system oil is avail-

able in 20.7 gram bottles. One bottle is sufficient for 15–22 liters of hydraulic oil. Order Part No. 44-2500 from your authorized Toro dealer.

1. Park the machine on a level surface. Make sure it has

cooled down so the oil is cold. Check the level of oil by viewing the sight gauge on the side of auxiliary oil tank.

2. If the oil level is below FULL mark on auxiliary tank,

remove cap from the hydraulic oil tank and slowly fill with Mobil DTE 26 or equivalent hydraulic oil until the level is up to the mark next to the sight gauge. Install the cap.

IMPORTANT To prevent system contamination, clean the top of the hydraulic oil containers before puncturing. Make sure the pour spout and funnel are clean.

NOTE: Make a close visual inspection of the hydraulic compo-

nents. Inspect for leaks, loose fasteners, missing parts, improperly routed lines, etc. Make any corrections necessary.

TIRE PRESSURE

The tires are over-inflated at the factory for shipping. Reduce the tire pressure to the proper levels before starting the unit.

Vary the tire pressure for the drive wheels, depending on your turf conditions, from a minimum of 55 KPa to a maximum of 83 KPa

Vary the tire pressure for the rear wheel from a minimum of 55 KPa to a maximum of 103 KPa. Traction improves with lower tire pressure.

First-Time Operation

BREAK-IN PERIOD

1. Refer to the Engine Manual supplied with the

Greensmaster 3100 for oil change and maintenance procedures recommended during break-in.

2. Only 8 hours of mowing operation is required for

the Greensmaster 3100 break-in period.

3. The first hours of operation are critical to future

dependability. Monitor performance closely so that minor difficulties that could lead to major problems can be corrected. Inspect the machine often during break-in for signs of oil leakage, loose fasteners, or any other malfunction.

STARTING INSTRUCTIONS

Note: Inspect the areas beneath the mowers to make sure they are clear of debris.

1. Sit on the seat, place the shift selector in NEU-

TRAL, and check the mow and lift pedals to make sure they are level with one another.

B. Operate the lift pedal; the cutting reels should

stop and the cutting units raise to full transport position.

NOTE: Stop the engine. Check the lip of each basket to be sure it doesn’t contact the reel dur ing operation. Re-adjust if the basket does make contact.

C. Depress the brake pedal to keep the machine

from moving and operate the traction pedal through the forward and reverse positions. Continue the above procedure for 1–2 minutes.

D. Neutralize the traction lever and the mow and

lift pedals, lock the parking brake, and turn the engine off. Check for oil leaks; if oil leaks appear, check the tightness of the hydraulic fittings. If oil leaks continue to appear, contact your local TORO dealer for assistance and, if necessary, replacement parts.

IMPORTANT: The motor or wheel seals may show some trace of oil for a short period of time until the break-in period is completed.

2. Remove your foot from the traction pedal and

make sure the pedal is in neutral.

3. Move the choke lever to ON—when starting a cold

engine—and the throttle lever to the half-throttle position.

4. Insert and turn the ignition key clockwise until the

engine starts. After the engine starts, regulate the choke to keep the engine running smoothly. As soon as possible, open the choke by pulling it rearward to the OFF position. A warm engine requires little or no choking.

5. Check the machine out with the following proce-

dures after the engine has started:

A. Move the throttle control to FAST and

momentarily engage the reels by depressing the mow pedal (the cutting units should drop and all reels should turn).

NOTE: When the Greensmaster 3100 is new and the bearings and reels are tight, it is necessary to use the FAST throttle control position for this check. A fast throttle setting may not be required after break-in.

CHECK THE INTERLOCK SYSTEM OPERATION

The interlock system prevents the engine from cranking or starting unless the operator is on the seat, the shift selector is in NEUTRAL and the cutting units are DISENGAGED. Also, the engine will stop when the cutting units are engaged or if the shift selector is in the No. 1 or No. 2 position with operator off the seat. Do the following system checks daily to make sure the interlock system operates correctly.

Page 16

CAUTION

The interlock switches are for the operator’s protection, so do not disconnect them. Check switch operation daily to assure the interlock system is operating. If a switch is defective, replace it before operating. Regardless of whether the switches are operating properly, replace them every two years to assure maximum safety. Do not rely entirely on safety switches—use common sense!

1. Engage the parking brake, move the shift selector to neu-

tral, remove your foot from the traction pedal and make sure the pedal is in neutral, and depress the lift pedal and release it. Rise off the seat and try to start the engine. The engine should not crank, which means the interlock system is operating correctly. If the engine did not crank, go to step 2. If the engine cranked, contact your local TORO dealer for assistance.

2. Sit on the seat, engage the parking brake and depress the

lift pedal fully and release it. Move the shift selector to the #1 and #2 positions while trying to start the engine in each position. The engine should not crank, which means the traction switch on the valve bank is operating correctly. If the engine did not crank, go to step 3. If the engine cranked, contact your local TORO dealer for assistance.

3. Sit on the seat, engage the parking brake, depress the lift

pedal and release it. Move the shift selector to Neutral and try to start the engine. The engine should start and continue to run, which means the traction switch and the mow/lift switch on valve bank are operating correctly—go to step 4. If the engine cranked but did not start, the problem is not in the interlock system. If the engine did not crank, contact your local TORO dealer for assistance.

4. Sit on the seat, engage the parking brake and move the shift

selector to neutral. Depress the mow pedal and try to start the engine. The engine should not crank, which means the mow-lift switch is operating correctly. If the engine did not crank, go to step 5. If the engine cranked, ask your local TORO dealer for assistance.

5. Sit on the seat, move the shift selector to Neutral, depress

the lift pedal and release it. Start the engine and drive to an open area that is free of debris and foreign objects. Keep all people, especially children, away from the front of the

Figure 8

Page 17

machine and out of the area of operation. Move the shift selector to Neutral, make sure the mow pedal is disengaged, set the throttle control at half speed and engage the parking brake. Hold the steering wheel, brace your feet on the foot deck and brake pedal, and move the shift selector to the #1 position. Carefully rise off the seat; the engine should stop. If the engine stops, the interlock system is operating correctly. Repeat this check with the shift selector in the #2 position. If the engine does not stop, stop the engine and find the problem before operating the machine. If you need assistance, contact your local TORO dealer.

CHECK THE LEAK DETECTOR’S OPERATION

The TURF GUARDIAN™ leak detector detects hydraulic oil system leaks. If the oil level in the main hydraulic reservoir is lowered by 4 to 6 ounces, the float switch in the tank will close. After a 1-second delay, the alarm will sound. Expansion of oil, due to normal heating during machine operation, will cause oil to transfer into the auxiliary oil reservoir. The oil is allowed to return to the main tank when the ignition switch is turned off.

2. Either place a strip of white tape or paint a line onto each

basket paralleling the outer edge of each basket (Fig. 13).

TRAINING PERIOD

Before mowing greens with the GREENSMASTER 3100, we suggest that you find a clear area and practice starting and stopping, raising and lowering the cutting units, turning, etc. This will help you gain confidence in the performance of the GREENSMASTER 3100.

IMPORTANT. If you shift to the No. 2 position while cutting greens, no increase in speed will result. However, a sudden Increase In speed will develop when you actuate the lift pedal. For safety, use only the No. 1 position for cutting greens and the No. 2 position for transport.

Operating

BEFORE MOWING

Inspect the green for debris, remove the flag from the cup, and determine the best direction in which to mow. Always mow in an alternate pattern from the previous mowing, so that the grass blades will be less apt to lay down and become difficult to cut.

MOWING PROCEDURES

1. Approach the green with the shift selector in the

number 1 position. Start on one edge of the green so the ribbon procedure of cutting may be used. This holds compaction to a minimum and leaves a neat, attractive pattern on the greens.

IMPORTANT: Shift to the No. 1 position when approaching a green because machine speed will automatically be reduced when the cutting units are engaged. Higher speed will resume when the cutting units are disengaged.

2. Actuate the mow pedal as the front edge of the grass

baskets cross the outer edge of the green. This procedure drops the cutting units to the turf and starts the reels.

NOTE: The No. 1 (rear) cutting unit reel will not start until all the cutting units are on the ground and No. 2 and No. 3 cutting units are cutting.

IMPORTANT Remember that the No. 1 cutting unit reel is delayed and therefore, you should practice to gain the timing necessary to minimize the clean-up mowing operation.

3. Overlap a minimal amount with the previous cut on

return passes. To maintain a straight line across the green and keep the machine an equal distance from the edge of the previous cut, establish an imaginary sight line 2 to 3 meters ahead of the machine to the edge of the uncut portion of the green (Fig. 13 & 14). Some people find it useful to include the outer edge of the steering wheel as part of the sight line; i.e., keep the steering wheel edge aligned with a point that is always kept the same distance away from the front of the machine (Fig. 13 & 14).

4. As the front of the baskets cross the edge of the

green, depress the lift pedal. This will stop the reels and lift the cutting units. Timing of this procedure is important, so the mowers do not cut into the fringe area. However, as much of the green as possible should be cut to minimize the amount of grass left to mow around the outer periphery.

5. Cut down on operating time and ease line-up for the

next pass by momentarily turning the machine in the opposite direction, then turning in the direction of the uncut portion; i.e., if intending to turn right, first swing slightly left, then right. This will help get the machine more quickly aligned for the next pass. Follow the same procedure for turning in the opposite direction. It’s good practice to try to make as short a turn as possible. However, turn in a wider arc during warmer weather to avoid bruising the turf.

NOTE: Due to the nature of the power steering system, the steering wheel will not return to its original position after a turn has been completed.

IMPORTANT: Never stop on a green with the cutting unit reels operating because you may damage the turf. Stopping on a wet green with the Greens–master 3100 may leave marks or indentations from the wheels.

6. If the leak detector alarm sounds while cutting on a

green, immediately raise the cutting units, drive directly off the green and stop the machine in a area away from the green. Find out what caused the alarm and correct the problem.

IMPORTANT: Prolonged idling of the machine after heavy use may cause a false alarm in the leak detector system, due to oil contraction as it cools. If this occurs, turn the engine off for a minute while the main hydraulic tank is refilled from the auxiliary tank.

7. Finish cutting the green by mowing the outer

periphery. Be sure to change the direction of cutting from the previous mowing. Always keep weather and turf conditions in mind and be sure to change the direction of mowing from the previous

Page 20

cutting. Replace the flag.

8. Empty the grass baskets of all clippings before transporting

to the next green. Heavy wet clippings place an undue strain on the baskets and will add unnecessary weight to the machine, thereby increasing the load on the engine, hydraulic system, brakes, etc.

LEAK DETECTOR OPERATION

The leak detector alarm may sound for one of the following reasons:

1. A leak has occurred.

2. The oil level in the main reservoir is reduced by 4 to 6

ounces due to oil contraction from cooling.

If the alarm sounds, turn it off as quickly as possible and inspect for leaks. If the alarm sounds while operating on a green, drive off the green first. Determine the source of the leak and repair it before continuing operation. If a leak is not found and a false leak is suspected, move the ignition switch to OFF and let the machine stand for 1–2 minutes to allow the oil levels to stabilize. Then start the machine and operate in a non-sensitive area to confirm that no leak exists.

False alarms due to oil contraction may be caused by extended idling after normal operation. A false alarm may also occur if the machine is worked at a reduced work load after an extended period of heavier work. To avoid false alarms, turn the machine off rather than letting it idle for extended periods.

INSPECTION AND CLEAN-UP AFTER MOWING

After mowing, thoroughly wash the machine. Use a garden hose without a nozzle so excessive water pressure doesn’t contaminate and damage seals and bearings. After cleaning, inspect the machine for possible hydraulic fluid leaks, damage or wear to the hydraulic and mechanical components. Also check the cutting units for sharpness. Lubricate the mow and lift pedal and the brake shaft assembly with SAE 30 oil or spray lubricant to deter corrosion and keep the machine performing well during the next mowing operation.

TRANSPORT OPERATION

Make sure the cutting units are in the highest UP position. Set the shift selector in No. 2 if conditions will permit faster ground speed. In rough or hilly areas, shift to No. 1 and operate at slower ground speeds. Use the brakes to slow the machine while going down steep hills to avoid loss of control. Always approach rough areas at a reduced speed (shift selector in No.

1), and cross severe undulations carefully. Familiarize yourself with the width of the machine. Do not attempt to pass between objects that are close together so that you can prevent costly damage and down time.
