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 fuel stabilizer/conditioner to the fuel.

  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. Shut off the engine and set the parking brake.

2. Clean around fuel tank cap and remove the cap. Add unleaded regular gasoline to fuel tank, until the level is 6 to 13 mm (1/4 to 1/2 inch) below the bottom of the filler neck. This space in the tank allows gasoline to expand. Do not fill the fuel tank completely full.

3. Install fuel tank cap securely. Wipe up any spilled gasoline.

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 following occurs:

• 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 shut off the engine when the traction controls are moved 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 the user when the interlock component is in the correct position. When the component is in the correct position, a triangle will light up in the corresponding square.

Figure 18

1. Triangles light up when the interlock components are in the correct position

Transport Lock Positions

1. Transport lock
2. Lock position—The mower deck locks into the TRANSPORT position.
3. Unlock position—The mower deck does not lock into the TRANSPORT position.

Adjust the height of cut from 25 to 140 mm (1 to 5-1/2 inches) in 6 mm (1/4 inch) increments by moving the clevis pin into different hole locations.

1. Move the transport lock to the LOCK position.

2. Push the deck-lift pedal with your foot and raise the mower deck to the TRANSPORT position (also the 140 mm (5-1/2 inch) cutting-height position) as shown in Figure 23.

3. To adjust, rotate the pin 90° and remove the pin from the height-of-cut bracket (Figure 23).

4. Select a hole in the height-of-cut bracket corresponding to the height-of-cut desired and insert the pin (Figure 23).

This is the full rear position. The suggested use for this position is a follows:

• Use for short, light grass mowing conditions

• Use in dry conditions

• For smaller grass clippings

• Propels grass clippings farther away from the mower

  

  Figure 28

Use this position when bagging. Always align it with the blower opening.

Figure 29

This is the full open position. The suggested use for this position is as follows:

• Use in tall, dense grass mowing conditions

• Use in wet conditions

• Lowers the engine power consumption

• Allows increased ground speed in heavy conditions

• This position is similar to the benefits of the Toro SFS mower.

  

  Figure 30

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 the cutting height of the mower does not scalp any uneven ground. However, the cutting height used in the past is generally the best to use. When cutting grass longer than 15 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 1/3 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.

Grass grows at different rates at different times. So to maintain the same cutting height, mow more often in early spring. As the grass growth rate slows in midsummer, 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 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 the 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.

Lubricate the deck-lift pivots.

Figure 36

Important: Make sure that the cutting unit spindles are full of grease weekly.

1. Disengage the blade-control switch (PTO), move the motion-control levers to the NEUTRAL-LOCK position, and set the parking brake.

2. Shut off the engine, remove the key, and wait for all moving parts to stop before leaving the operating position.

3. Grease the mower deck idler pulley pivot until grease comes out the bottom (Figure 37).

4. Grease the 3 spindle bearings until grease comes out the lower seals (Figure 37).

   

   Figure 37

5. Grease the drive belt idler arm (Figure 37).

   

   Figure 38

6. Remove the dust cap and adjust the caster pivots.

   Note: Keep the dust cap off until greasing is complete. Refer to Adjusting the Caster-Pivot Bearing.

7. Remove the hex plug and thread a grease fitting into the hole.

   2. Spacer nut with wrench flats

2. Raise the front of the machine up and support it with jack stands.

3. Remove the caster wheel from the caster forks.

4. Remove the seal guards from the wheel hub.

5. Remove 1 of the spacer nuts from the axle assembly in the caster wheel.

   Note: Note that thread-locking adhesive has been applied to lock the spacer nuts to the axle. Remove the axle (with the other spacer nut still assembled to it) from the wheel assembly.

6. Pry out the seals and inspect the bearings for wear or damage and replace them 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 the axle assembly has had both spacer nuts removed (or broken loose), apply a thread locking adhesive to 1 spacer nut and thread it onto the axle with the wrench flats facing outward.

   Note: Do not thread the spacer nut all 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 of the wheel 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 adhesive 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, then torque it again 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 the wheel into the caster fork. 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 thread locking adhesive.

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

Oil Type: Detergent oil (API service SJ or higher)

Oil Capacity: with a filter change—1.65 L (56 oz); without a filter change—1.50 L (51 oz)

Viscosity: See the table below.

Figure 43

Note: Use of synthetic oil having 5W-20 or 5W-30 rating is acceptable, up to 4°C (40°F).

Note: Synthetic oils provide better starting in extreme cold below -23°C (-10°F).

Ensure that 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 : Champion^® XC12YC, or equivalent

Air Gap: 0.76 mm (0.030 inch)

Checking the Spark Plug

Important: Replace the spark plug(s) when it has: a black coating, worn electrodes, an oily film, cracks or reuse is questionable.

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

Set the gap to 0.76 mm (0.030 inches).

Located on either side of the fuel tank, below the seat are the pump-control linkages. Rotating the pump linkage with a 1/2 inch wrench allows fine-tuning adjustments so that the machine does not move in neutral. Any adjustments should be made for neutral positioning only.

1. Prior to starting the engine, push the deck-lift pedal and remove the height-of-cut pin. Lower the deck to the ground.

2. Raise the rear of machine up and support it with jack stands (or equivalent support) just high enough to allow the drive wheels to turn freely.

3. Remove the electrical connection from the seat safety switch, located under the bottom cushion of the seat.

   Note: The switch is a part of the seat assembly.

4. Temporarily install a jumper wire across the terminals in the connector of the main wiring harness.

5. Start the engine.

   Important: Before you can start the engine, the brake must be engaged and the motion-control levers must be out. You do not need to be in the seat because of the jumper wire is in use. Run the engine at full throttle and release the brake.

6. Run the machine at least 5 minutes with the motion-control levers at full forward speed to bring the hydraulic fluid up to operating temperature.

   Note: The motion-control lever must be in neutral while making any necessary adjustments.

7. Bring the motion-control levers into the NEUTRAL position.

8. Adjust the length of the pump-control rod by rotating the double nuts on the rod in the appropriate direction until the wheels slightly creep in reverse (Figure 78).

   

   Figure 78

   1. Double nuts

9. Move the motion-control levers to the REVERSE position, and while applying slight pressure to the lever, allow the reverse indicator springs to bring the levers back to neutral.

   Note: The wheels must stop turning or slightly creep in reverse.

10. Shut off the machine.

11. Remove the jumper wire from the wire harness and plug the connector into the seat switch.

12. Remove the jack stands.

13. Raise the deck and install the height-of-cut pin.

14. Check that the machine does not creep in neutral with the parking brakes disengaged.

You can adjust the top damper-mounting bolt to obtain the desired motion-control lever resistance. Refer to Figure 79 for mounting options.

Figure 79

Right Motion Control Shown

1. Torque the locknut to 23 N-m (17 ft-lb). The bolt must protrude past the end of the locknut after torquing.
2. Most resistance (firmest feel)
3. Damper
4. Medium resistance (medium feel)
5. Least resistance (softest feel)

You can adjust the flanged nut to obtain the desired motion-control lever resistance when moving it to the NEUTRAL-LOCK position. See Figure 80 for adjustment options.

1. Loosen the jam nut.

2. Tighten or loosen the flanged nut to the desired feel.

   • For more resistance, tighten the flanged nut.

   • For less resistance, loosen the flanged nut

3. Tighten the jam nut.

Hydraulic Fluid Type: Toro^® HYPR-OIL^™ 500 hydraulic fluid or Mobil^® 1 15W-50.

Important: Use the hydraulic fluid specified. Other fluids could damage the hydraulic system.

Hydraulic System Capacity: 1.5 L (52 oz) per side with filter change

Maintain sharp blades throughout the cutting season, because sharp blades cut 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. For convenient sharpening and replacement, keep extra blades on hand.

Lock out the spring-loaded deck arms before servicing or removing the mower deck.

1. Shut off the engine, wait for all of the moving parts to stop, remove the key, and engage the parking brake.

2. Remove the height-adjustment pin and lower the deck to the ground.

3. Place the height adjustment pin in the 7.6 cm (3 inch) cutting-height location.

   Note: This locks the deck-lift arms in the lowest position when the deck is removed and the stored energy in the deck spring is released.

4. Remove the belt covers.

5. Lift up the floor pan and insert a ratchet into the square hole in the deck idler (Figure 95).

6. Rotate the deck idler clockwise and remove the mower belt (Figure 95).
