TimeCutter® Riding Mowers

• For best results, use only clean, fresh (less than 30 days old), unleaded gasoline with an octane rating of 87 or higher ((R+M)/2 rating method).

• Ethanol: Gasoline with up to 10% ethanol (gasohol) or 15% MTBE (methyl tertiary butyl ether) by volume is acceptable. Ethanol and MTBE are not the same. Gasoline with 15% ethanol (E15) by volume is not approved for use. Never use gasoline that contains more than 10% ethanol by volume, such as E15 (contains 15% ethanol), E20 (contains 20% ethanol), or E85 (contains up to 85% ethanol). Using unapproved gasoline may cause performance problems and/or engine damage which may not be covered under warranty.

• Do not use gasoline containing methanol.

• Do not store fuel either in the fuel tank or fuel containers over the winter unless you use a fuel stabilizer.

• Do not add oil to gasoline.

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

• Keeps fuel fresh longer when used as directed by the fuel-stabilizer manufacturer

• 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 fuel. To minimize the chance of varnish deposits in the fuel system, use fuel stabilizer at all times.

1. Park the machine on a level surface.

2. Engage the parking brake.

3. Shut off the engine and remove the key.

4. Clean around the fuel-tank cap.

5. Fill the fuel tank to the bottom of the filler neck (Figure 9).

   Note: Do not fill the fuel tank completely full. The empty space in the tank allows the fuel to expand.

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 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

• Trimming grass

Tow

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

• Bagging

• Mulching

• Towing attachments

Mow

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

• Normal mowing

• Moving the machine

Whenever you change the height of cut, adjust the height of the anti-scalp rollers.

Note: Adjust the anti-scalp rollers so that the rollers do not touch the ground in normal, flat mowing areas.

1. Disengage the blade-control switch (PTO), move the motion-control levers to the NEUTRAL-LOCK position, and engage 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. Adjust the anti-scalp rollers as shown in Figure 30 to match the closest height-of-cut position.

   

   Figure 30

4. Align the bolt and anti-scalp roller in the hole of the bracket that matched the closest height-of-cut position (Figure 31).

5. Insert the bolt into the bracket hole and secure the bolt and anti-scalp roller with the flange nut (Figure 31).

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 deck in uncut grass. Always try to have 1 side of the mower deck free from uncut grass, which allows air to be drawn into the mower deck.

Cut grass slightly longer than normal to ensure that the cutting height of the mower deck 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 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 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.

Grass grows at different rates at different times of the year. To maintain the same cutting height, 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.

When mowing uneven turf, raise the cutting height to avoid scalping the turf.

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 or you can disengage the mower deck while moving forward.

Clean clippings and dirt from the underside of the mower deck after each use. If grass and dirt build up inside the mower deck, 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 mower blades after each use 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.

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