TimeCutter® SS 4225 Riding Mower

• Read, understand, and follow all instructions in the operator's manual and on the machine before starting.

• Do not place hands or feet near rotating parts or under the machine. Keep clear of the discharge opening at all times.

• Allow only responsible adults who are familiar with the instructions to operate the machine.

• Clear the area of objects such as rocks, toys, wire, etc., which could be picked up and thrown by the blade.

• Be sure the area is clear of other people before mowing. Stop the machine if anyone enters the area.

• Never carry passengers.

• Do not mow in reverse unless absolutely necessary. Always look down and behind before and while backing up.

• Be aware of the mower discharge direction and do not point it at anyone. Avoid discharging material against a wall or obstruction. Material may ricochet back toward the operator. Stop the blade(s) when crossing gravel surfaces.

• Do not operate the machine without deflector, discharge cover or entire grass collection system in place and working.

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

• Never leave a running machine unattended. Always turn off blades, set parking brake, stop engine, and remove key before dismounting.

• Turn off blades when not mowing. Stop the engine, wait for all parts to come to a complete stop and remove the key before cleaning the machine, removing the grass catcher or unclogging the discharge chute.

• Operate the machine only in daylight or good artificial light.

• Do not operate the machine while under the influence of alcohol or drugs.

• Watch for traffic when operating near or crossing roadways.

• Use extra care when loading or unloading the machine into a trailer or truck.

• Always wear eye protection when operating the mower.

• Always follow the recommendations for any application of counterweights.

• 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.

Slopes are a major factor related to loss of control and tip-over accidents, which can result in severe injury or death. Operation on all slopes requires extra caution. If you cannot back up the slope or if you feel uneasy on it, do not mow it.

• Do not mow slopes greater than 15 degrees.

• Watch for ditches, holes, rocks, dips, and rises that change the operating angle, as rough terrain could overturn the machine.

• Choose a low ground speed so you will not have to stop while operating on a slope.

• Do not mow slopes when grass is wet. Slippery conditions reduce traction and could cause sliding and loss of control.

• Always keep the drive wheels engaged when going down slopes.

• Reduce speed and use extreme caution on slopes.

• Do not make sudden turns or rapid speed changes.

• Remove or mark obstacles such as rocks, tree limbs, etc. from the mowing area. Tall grass can hide obstacles.

• Avoid sudden starts when mowing uphill because the mower may tip backwards.

• Be aware that loss of traction may occur going downhill. Weight transfer to the front wheels may cause drive wheels to slip and cause loss of braking and steering.

• Always avoid sudden starting or stopping on a slope. If tires lose traction, stop the machine, disengage the blades and proceed slowly off the slope.

• Use extreme care with grass catchers or other attachments. These can change the stability of the machine and cause loss of control.

• Do not try to stabilize the machine by putting your foot on the ground.

• Do not mow near drop-offs, ditches, steep banks or water. Wheels dropping over edges can cause rollovers, which may result in serious injury, death or drowning.

• Use a walk behind mower and/or a hand trimmer near drop-offs, ditches, steep banks or water.

Tragic accidents can occur if the operator is not alert to the presence of children. Children are often attracted to the machine and the mowing activity. Never assume that children will remain where you last saw them.

• Keep children out of the mowing area and under the watchful care of another responsible adult, not the operator.

• Be alert and turn the machine off if children enter the area.

• Before and while backing or changing direction, look behind, down, and side-to-side for small children.

• Never carry children, even with the blades off. They may fall off and be seriously injured or interfere with safe machine operation.

• Children who have been given rides in the past may suddenly appear in the mowing area for another ride and be run over or backed over by the mower.

• Never allow children to operate the machine.

• Use extra care when approaching blind corners, shrubs, trees, the end of a fence or other objects that may obscure vision.

Safe Handling of Gasoline:

To avoid personal injury or property damage, use extra care when handling gasoline and other fuels. They are flammable and the vapors are explosive.

• Extinguish all cigarettes, cigars, pipes and other sources of ignition.

• Use only an approved container.

• Never remove the gas cap or add fuel when the engine is running. Allow the engine to cool before refueling.

• Never refuel the machine indoors.

• Never store the machine or fuel container inside where there is an open flame, such as near a water heater or furnace.

• Never fill containers inside a vehicle or on a truck or trailer with a plastic liner. Always place containers on the ground away from your vehicle before filling.

• Remove gas-powered equipment from the truck or trailer and refuel it on the ground. If this is not possible, then refuel such equipment with a portable container, rather than from a gasoline dispenser nozzle.

• Keep the nozzle in contact with the rim of the fuel tank or container opening at all times until the fueling is complete. Do not use a nozzle lock-open device.

• If fuel is spilled on clothing, change clothing immediately.

• Never overfill the fuel tank. Replace gas cap and tighten securely.

  General Service:

• Never operate a machine inside a closed area. Engine exhaust contains carbon monoxide, which is an odorless, deadly poison that can kill you.

• Keep nuts and bolts tight, especially the blade attachment bolts. Keep equipment in good condition.

• Never interfere with the intended function of a safety device or to reduce the protection provided by a safety device. Check their proper operation regularly.

• Keep the machine free of grass, leaves, or other debris build-up. Clean up oil or fuel spillage fuel soaked debris. Allow the machine to cool before storing.

• Stop and inspect the equipment if you strike an object. Repair, if necessary, before restarting.

• Never make any adjustments or repairs with the engine running.

• Grass catcher components are subject to wear, damage and deterioration, which could expose moving parts or allow objects to be thrown. Frequently check components and replace with manufacturers' recommended parts, when necessary.

• Mower blades are sharp and can cut. Wrap the blade(s) or wear thickly-padded gloves, and use extra caution when servicing them.

• Check for proper brake operation frequently. Adjust and service as required.

• Maintain or replace safety and instruction decals as necessary.

• Use only genuine Toro replacement parts to ensure that original standards are maintained.

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 gas stabilizer/conditioner to the gas.

  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.

Note: Ensure that the engine is shut off and the motion controls are in the parked position.

Note: You can use the fuel window to verify the presence of gasoline before filling the tank (Figure 7).

Important: Do not overfill fuel tank. Fill the fuel tank to the bottom of the filler neck. The empty space in the tank allows the fuel to expand. Overfilling may result in fuel leakage, damage to the engine, or damage to the emissions system.

Figure 7

Important: Do not engage the blades when parked in tall grass. Belt or clutch damage can occur.

Note: Always engage the blades with the throttle in the Fast position.

Figure 11

The Smart Speed ^TM Control-System lever, located below the operating position (Figure 14), gives the operator a choice to drive the machine at 3 ground speed ranges—trim, tow, and mow.

Figure 14

1. Smart speed lever

To change speeds, do the following:

1. Move the motion control levers to neutral and outward to the park position.

2. Disengage the blade control switch

3. Adjust the lever to the desired position.

The following are only recommendations for use. Adjustments will vary by grass type, moisture content, and the height of the grass.

Trim

This is the lowest speed. The suggested uses for this speed are as follows:

• Parking

• Heavy, wet grass mowing conditions

• Training

Tow

This is the medium speed. The suggested uses for this speed are as follows:

• Bagging

• Mulching

Mow

This is the fastest speed. The suggested uses for this speed are as follows:

• Normal mowing

• Transporting the machine

Note: Always use caution when backing up and turning.

1. Move the levers to the center, unlocked position.

2. To go forward, slowly push the motion-control levers forward (Figure 15).

   

   Figure 15

   To go straight, apply equal pressure to both motion-control levers (Figure 15).

   To turn, release pressure on the motion-control lever toward the direction you want to turn (Figure 15).

   The farther you move the motion-control levers in either direction, the faster the machine will move in that direction.

   To stop, pull the motion-control levers to neutral.

Note: Always use caution when backing up and turning.

1. Move the levers to the center, unlocked position.

2. To go backward, look behind you and down, as you slowly pull the motion-control levers rearward (Figure 16).

   

   Figure 16

   To go straight, apply equal pressure to both motion-control levers (Figure 16).

   To turn, release the pressure on the motion-control lever toward the direction you want to turn.

   To stop, push the motion-control levers to neutral.

The motion-control levers can be adjusted higher or lower for maximum operator comfort (Figure 20).

Figure 20

The motion-control levers can be tilted fore or aft for maximum operator comfort.

1. Loosen the upper bolt holding the control lever to the control-arm shaft.

2. Loosen the lower bolt just enough to pivot the control lever fore or aft (Figure 20). Tighten both bolts to secure the control in the new position.

3. Repeat the adjustment for the opposite control lever.

1. Park the machine on a level surface, and disengage the blade-control switch.

2. Move the motion-control levers outward to the park position, stop the engine, and wait for all moving parts to stop before leaving the operating position.

3. Locate the bypass levers on the frame on both sides of the engine.

4. Move the bypass levers forward through the key hole and down to lock them in place (Figure 21).

   Note: Ensure this is done for each lever.

5. Move the motion-control levers inward to the neutral position and turn the ignition key to the Run position.

   Note: Do not start the machine.

   Note: The machine is now able to be pushed by hand.

6. When finished, ensure that the key has been returned to the Stop position to avoid draining the battery charge.

Note: If the machine fails to move, the electric brake may still be engaged. If necessary, the electric brake can be released manually; refer to Releasing the Electric Brake.

Move the bypass levers rearward through the key hole and down to lock them in place as shown in Figure 21.

Note: Ensure this is done for each lever.

For best mowing and maximum air circulation, operate the engine at the Fast 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 by uncut grass. Always try to have one side of the mower free from uncut grass, which allows air to be drawn into the mower.

The Smart Speed™ Control System lever, located below the operating position, gives the operator a choice to drive the machine at three speed ranges—high, tow, and low. An operator can benefit from the lower speed setting when maneuvering the machine in tight spaces or operating around delicate landscapes. The low setting can also be used to operate the machine at a high throttle setting and blade speed while still being able to reduce ground speed to increase quality of cut.

Cut grass slightly longer than normal to ensure that the cutting height of the mower does not scalp any uneven ground. However, the cutting height used in the past is generally the best one to use. When cutting grass longer than six 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 mowing direction to keep the grass standing straight. This also helps disperse clippings which enhances decomposition and fertilization.

Normally, mow every four days. But remember, grass grows at different rates at different times. So 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 two days later at a lower height setting.

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 the machine's forward motion must be stopped 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, cutting quality will eventually become 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.

Make sure that the motion-control levers are locked in the park position. Lift the seat forward.

The following components can be accessed by raising the seat:

• Serial plate

• Service decal

• Seat adjustment bolts

• Fuel filter

• Battery and battery cables

Grease Type: No. 2 general purpose, lithium-based grease

1. Park the machine on a level surface, and disengage the blade-control switch.

2. Move the motion-control levers outward to the park position, stop the engine, remove the key, and wait for all moving parts to stop before leaving the operating position.

3. Clean the grease fittings (Figure 25 and Figure 26) with a rag.

   Note: Make sure to scrape any paint off the front of the fitting(s).

This engine is equipped with a replaceable, high density paper air-cleaner element. Check the air cleaner daily or before starting the engine. Check for a buildup of dirt and debris around the air-cleaner system. Keep this area clean. Also, check for loose or damaged components. Replace all bent or damaged air-cleaner components.

Note: Operating the engine with loose or damaged air-cleaner components could allow unfiltered air into the engine, causing premature wear and failure.

Note: Service the air cleaner more often under extremely dusty, dirty conditions.

1. Rotate the latches outward.

2. Remove the cover to access the air-cleaner element ().

3. Remove the element, and gently tap the element to dislodge dirt.

   Note: Do not wash the paper element or use pressurized air, as this will damage the element.

   Note: Replace a dirty, bent, or damaged element. Handle the new element carefully; do not use if the sealing surfaces are bent or damaged.

4. Clean the air-cleaner base as required, and check the condition.

5. Install the paper element onto the air-cleaner base.

Viscosity: See the table below.

Figure 28

The spark plug is RFI compliant. Equivalent alternate brand plugs can also be used.

Type: Champion XC12YC

Air Gap: 0.76 mm (0.03 inch)

Checking the Spark Plug

Important: Do not clean the spark plug(s). Always replace the spark plug(s) when it has: a black coating, worn electrodes, an oily film, or cracks.

Note: 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 inch).

Figure 34

Installing the Spark Plug

Tighten the spark plug to 25 to 29 N-m (18 to 22 ft-lb).

Figure 35

To ensure proper cooling, make sure the grass screen, cooling fins, and other external surfaces of the engine are kept clean at all times.

Annually, or every 100 hours of operation (more often under extremely dusty, dirty conditions), remove the blower housing, and any other cooling shrouds. Clean the cooling fins and external surfaces as necessary. Make sure the cooling shrouds are installed. Torque the blower housing screws to 7.5 N-m (5.5 ft-lb).

Important: Operating the engine with a blocked grass screen, dirty or plugged cooling fins, and/or cooling shrouds removed, will cause engine damage due to overheating.

Never install a dirty filter if it is removed from the fuel line.

1. Park the machine on a level surface and disengage the blade-control switch.

2. Move the motion-control levers outward to the park position, stop the engine, remove the key, and wait for all moving parts to stop before leaving the operating position.

3. Replace the in-line filter (Figure 36).

1. Turn the ignition key to the Off position or disconnect the battery.

2. Locate the shaft on the electric brake where the brake-link arms are connected.

3. Rotate the shaft forward to release the brake.

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, you may want to keep extra blades on hand.
