Z Master® Professional 6000 Series Riding Mower

• Read the instructions carefully. Be familiar with the controls and the proper use of the equipment.

• Never allow children or people unfamiliar with these instructions to use the lawn mower. Local regulations can restrict the age of the operator.

• Never mow while people, especially children, or pets are nearby.

• Keep in mind that the operator or user is responsible for accidents or hazards occurring to other people or their property.

• Do not carry passengers.

• All drivers should seek and obtain professional and practical instruction. Such instruction should emphasize:

  • 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 control levers. The main reasons for loss of control are:

    • insufficient wheel grip, especially on wet grass;

    • being driven too fast;

    • inadequate braking;

    • the type of machine is unsuitable for its task;

    • lack of awareness of the effect of ground conditions, especially slopes;

    • incorrect hitching and load distribution.

• While mowing, always wear substantial, slip-resistant footwear and long trousers. Tie back long hair. Do not wear jewelry.

• Thoroughly inspect the area where you will use the equipment and remove all objects which the machine may throw at you.

• Warning–Fuel is highly flammable.

  • Store fuel in containers specifically designed for this purpose.

  • Refuel the machine outdoors only and do not smoke while refuelling.

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

  • If you spill fuel, do not attempt to start the engine but move the machine away from the area of spillage and avoid creating any source of ignition until the fuel vapors have dissipated.

  • Replace all fuel tanks and container caps securely.

• Replace faulty silencers.

• Before using, always visually inspect to see that the blades, blade bolts, and cutter assembly are not worn or damaged. Replace worn or damaged blades and bolts in sets to preserve balance.

• On multi-bladed machines, take care as rotating one blade can cause other blades to rotate.

• Lightning can cause severe injury or death. If lightning is seen or thunder is heard in the area, do not operate the machine; seek shelter.

• Be alert, slow down, and use caution when making turns. Look behind and to the side before changing directions.

• Do not operate the engine in a confined space where dangerous carbon monoxide fumes can collect.

• Mow only in daylight or in good artificial light.

• Before attempting to start the engine, disengage all blade-attachment clutches and shift the transmission into neutral.

• Do not use on slopes greater than 15 degrees.

• Remember that 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 on a slope;

  • use slow speeds on slopes and during tight turns;

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

• Use care when pulling loads or using heavy equipment.

  • Use only approved drawbar hitch points.

  • Limit loads to those you can safely control.

  • Do not turn sharply. Use care when reversing the machine.

• Watch out for traffic when crossing or near roadways.

• Stop the blades rotating before crossing surfaces other than grass.

• When using any attachments, never direct discharge of material toward bystanders nor allow anyone near the machine while in operation.

• Never operate the machine with damaged guards or without safety protective devices in place.

• Do not change the engine governor settings or overspeed the engine. Operating the engine at excessive speed can increase the hazard of personal injury.

• Before leaving the operator's position:

  • disengage the power takeoff and lower the attachments;

  • change into neutral and set the parking brake;

  • stop the engine and remove the key.

• Disengage drive to attachments, stop the engine, and disconnect the spark plug wire(s) or remove the ignition key

  • before clearing blockages or unclogging the chute;

  • before checking, cleaning, or working on the lawn mower;

  • after striking a foreign object. Inspect the lawn mower for damage and make repairs before starting and operating the equipment; if the machine starts to vibrate abnormally (check immediately).

• Disengage drive to attachments when transporting or not in use.

• Stop the engine and disengage drive to attachment

  • before fuelling;

  • before removing the grass catcher;

  • before adjusting the height unless you can adjust it from the operator's position.

• Reduce the throttle setting during engine run-out and, if the engine is provided with a shutoff valve, turn the fuel off at the conclusion of mowing.

• Keep all nuts, bolts and screws tight to be sure that the equipment is in safe working condition.

• Never store the equipment with fuel in the tank inside a building, where fumes can reach an open flame or spark.

• Allow the engine to cool before storing the machine in any enclosure.

• To reduce the fire hazard, keep the engine, silencer, battery compartment, and fuel storage area free of grass, leaves, or excessive grease.

• Check the grass catcher frequently for wear or deterioration.

• Replace worn or damaged parts for safety.

• If you must drain the fuel tank, do it outdoors.

• When machine is to be parked, stored or left unattended, lower the cutting means unless you are using a positive mechanical lock.

Use a fuel stabilizer/conditioner in the machine to provide the following benefits:

• Keeps gasoline fresh during storage of 90 days or less. For longer storage it is recommended that the fuel tank be drained.

• Cleans the engine while it runs

• Eliminates gum-like varnish buildup in the fuel system, which causes hard starting

  Important: Do not use fuel additives containing methanol or ethanol.

  Add the correct amount of gasoline stabilizer/conditioner to the gasoline.

  Note: A fuel stabilizer/conditioner is most effective when mixed with fresh gasoline. To minimize the chance of varnish deposits in the fuel system, use fuel stabilizer at all times.

1. Park the machine on level ground.

2. Shut the engine off and set the parking brake.

3. Clean around the fuel-tank cap.

4. Fill the fuel tank to the bottom of the filler neck (Figure 7).

   Note: Ensure that there is empty space in the tank to allow the gasoline to expand

   Note: Do not fill the fuel tank completely full. Fill the fuel tank to the bottom of the filler neck.

   

   Figure 7

Important: Do not engage starter for more than 5 seconds at a time. If the engine fails to start, wait 15 seconds between attempts. Failure to follow these instructions can burn out the starter motor.

Figure 19

Figure 20

Important: Make sure that you close the fuel-shutoff valve before transporting or storing the machine, as fuel leakage may occur. Set the parking brake before transporting the machine. Make sure to remove the key as the fuel pump may run and cause the battery to lose charge.

The safety-interlock system is designed to prevent the engine from starting unless:

• The parking brake is engaged.

• The blade-control switch (PTO) is disengaged.

• The motion-control levers are in the NEUTRAL-LOCK position.

The safety-interlock system also is designed to stop the engine when you move the traction controls from the locked position with the parking brake engaged or if you rise from the seat when the PTO is engaged.

The hour meter has symbols to notify you when the interlock component is in the correct position. When the component is in the correct position, a triangle lights up in the corresponding square.

5. Return the stand to its rest position (Figure 40).

For best mowing and maximum air circulation, operate the engine at the FAST throttle position. Air is required to thoroughly cut grass clippings, so do not set the height of cut so low as to totally surround the mower in uncut grass. Always try to have 1 side of the mower free from uncut grass, which allows air to be drawn into the mower.

Cut the grass slightly longer than normal to ensure that the cutting height of the mower does not scalp any uneven ground. However, the cutting height you have used in the past is generally the best to use. When cutting grass longer than 15.24 cm (6 inches) tall, you may want to cut the lawn twice to ensure an acceptable quality of cut.

It is best to cut only about a third of the grass blade. Cutting more than that is not recommended unless grass is sparse, or it is late fall when grass grows more slowly.

Alternate the mowing direction to keep the grass standing straight. This also helps disperse clippings, which enhances decomposition and fertilization.

Normally, mow every 4 days. However, grass grows at different rates at different times. To maintain the same cutting height, which is a good practice, mow more often in early spring. As the grass growth rate slows in mid-summer, mow less frequently. If you cannot mow for an extended period, first mow at a high cutting height; then mow again 2 days later at a lower height setting.

To improve cut quality, use a slower ground speed in certain conditions.

If the cutting width of the mower is wider than the mower that you previously used, raise the cutting height to ensure that uneven turf is not cut too short.

If the grass is ever allowed to grow slightly longer than normal, or if it contains a high degree of moisture, raise the cutting height higher than usual and cut the grass at this setting. Then cut the grass again using the lower, normal setting.

If you must stop the forward motion of the machine while mowing, a clump of grass clippings may drop onto your lawn. To avoid this, move onto a previously cut area with the blades engaged.

Clean clippings and dirt from the underside of the mower after each use. If grass and dirt build up inside the mower, the cutting quality eventually becomes unsatisfactory.

Maintain a sharp blade throughout the cutting season, because a sharp blade cuts cleanly without tearing or shredding the grass blades. Tearing and shredding turns grass brown at the edges, which slows growth and increases the chance of disease. Check the cutter blades daily for sharpness and for any wear or damage. File down any nicks and sharpen the blades as necessary. If a blade is damaged or worn, replace it immediately with a genuine Toro replacement blade.

6. Pry out seals and inspect bearings for wear or damage and replace if necessary.

7. Pack the bearings with a general-purpose grease.

8. Insert 1 bearing and 1 new seal into the wheel.

   Note: Replace the seals.

9. If both spacer nuts have been removed (or broken loose) from the axle assembly, apply a thread-locking compound to 1 spacer nut and thread it onto the axle with the wrench flats facing outward.

   Note: Do not thread the spacer nut all of the way onto the end of the axle. Leave approximately 3 mm (1/8 inch) from the outer surface of the spacer nut to the end of the axle inside the nut.

10. Insert the assembled nut and axle into the wheel on the side with the new seal and bearing.

11. With the open end of the wheel facing up, fill the area inside the wheel around the axle full of general-purpose grease.

12. Insert the second bearing and new seal into the wheel.

13. Apply a thread-locking compound to the second spacer nut and thread it onto the axle with the wrench flats facing outward.

14. Torque the nut to 8 to 9 N∙m (75 to 80 in-lb), loosen the nut, then torque it to 2 to 3 N∙m (20 to 25 in-lb).

    Note: Make sure that the axle does not extend beyond either nut.

15. Install the seal guards over the wheel hub and insert wheel into the caster fork.

16. Install the caster bolt and tighten the nut fully.

Important: To prevent seal and bearing damage, check the bearing adjustment often. Spin the caster tire. The tire should not spin freely (more than 1 or 2 revolutions) or have any side play. If the wheel spins freely, adjust the torque on the spacer nut until there is a slight amount of drag. Apply another layer of thread-locking compound.

Note: Check the filters more frequently if the operating conditions are extremely dusty or sandy.

Oil Type: Detergent oil (API service SF, SG, SH, SJ, or SL)

Oil Capacity:

• Model 74919TE: with a filter change, 2.1 L (2.2 US qt); without a filter change, 1.8 L (1.9 US qt)

• Model 74925TE: with a filter change, 2.3 L (2.4 US qt); without a filter change, 2.1 L (2.2 US qt)

Viscosity: See the table below.

Figure 51

Note: Use of multi-grade oils (5W-20, 10W-30, or 10W-40) will increase oil consumption. Check the oil level more frequently when using them.

Make sure the air gap between the center and side electrodes is correct before installing the spark plug. Use a spark plug wrench for removing and installing the spark plug(s) and a gapping tool/feeler gauge to check and adjust the air gap. Install a new spark plug(s) if necessary.

Type of Spark Plug: NGK^® BPR4ES or equivalent

Air Gap: 0.76 mm (0.030 inch)

Checking the Spark Plug

Important: Never clean the spark plug(s). Always replace the spark plug(s) when it has: a black coating, worn electrodes, an oily film, or cracks.

If you see light brown or gray on the insulator, the engine is operating properly. A black coating on the insulator usually means the air cleaner is dirty.

Set the gap to 0.76 mm (0.030 inches).
