This manual uses two other words to highlight information. Important calls attention to special mechanical information and Note: emphasizes general information worthy of special attention. Introduction Read this manual carefully to learn how to operate and maintain your product properly. The information in this manual can help you and others avoid injury and product damage. Although Toro designs and produces safe products, you are responsible for operating the product properly and safely.
• Slow down and use caution when making turns and crossing roads and sidewalks. Stop blades if not mowing. • Use extra care when handling gasoline and other fuels. They are flammable and vapors are explosive. • Use only an approved container • Be aware of the mower discharge direction and do not point it at anyone. • Never remove gas cap or add fuel with engine running. Allow engine to cool before refueling. Do not smoke. • Do not operate the mower under the influence of alcohol or drugs.
This product is designed for cutting and recycling grass or, when equipped with a grass bagger, for catching cut grass. Any use for purposes other than these could prove dangerous to user and bystanders. General Operation • Be sure the area is clear of other people before mowing. Stop the machine if anyone enters the area. • Do not touch equipment or attachment parts which may be hot from operation. Allow to cool before attempting to maintain, adjust or service. • Use only Toro-approved attachments.
Slope Chart Fold along appropriate line Example: Compare slope with folded edge. Align this edge with a vertical surface (Tree, Building, Fence post, pole, etc.
Safety and Instruction Decals Safety decals and instructions are easily visible to the operator and are located near any area of potential danger. Replace any decal that is damaged or lost.

Gasoline and Oil Recommended Gasoline Warning Use UNLEADED Regular Gasoline suitable for automotive use (85 pump octane minimum). Leaded regular gasoline may be used if unleaded regular is not available. Gasoline is harmful or fatal if swallowed. Long–term exposure to vapors can cause serious injury and illness. Important Never use methanol, gasoline containing methanol, or gasohol containing more than 10% ethanol because the fuel system could be damaged. Do not mix oil with gasoline.

Drive machine until drive wheels contact curb (Fig. 21). Note: Lifting up on the lower handle will assist driving the machine up a curb and not spin the drive wheels. 6.
Using the Side Discharge This mower has a hinged grass deflector that disperses clippings to the side and down toward the turf. 2 Danger 2 1 Without the grass deflector, discharge cover, or complete grass catcher assembly mounted in place, you and others are exposed to blade contact and thrown debris. Contact with rotating mower blade(s) and thrown debris will cause injury or death. m–7630 Figure 22 1. Mower 2. Lift handle 3.
1. After adjusting height-of-cut, check the gage wheels so that there is a minimum of 3/8 inch (10 mm) clearance above the ground (Fig. 24). 2. Loosen the upper flange bolts (3/8 x 1 inch) and flange nut securing handle to rear frame (Fig. 26). 4 2. If adjustment is needed, remove the bolt, washers and nut (Fig. 24). 5 6 3. Select a hole position so the gage wheels are a minimum of 3/8 inch (10 mm) off the ground (Fig. 24). 2 1 4. Install the bolt, washers and nut (Fig. 24).

Metal end USE THESE SAE VISCOSITY OILS 10W–30 Changing the Oil 1. Start the engine and let it run five minutes.
8. Check the oil level; refer to Checking the Oil Level, page 28. Servicing the Spark Plug 9. Slowly add additional oil to bring it to the full mark. Service Interval/Specification Check the spark plug(s) after every 200 operating hours. 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.
2. Check the gap between the center and side electrodes (Fig. 34). Bend the side electrode (Fig. 34) if the gap is not correct. 2 2. Raise the rear of the machine and use jack stands to support the machine. 3. Remove the rear wheel and tire assembly. 3 4. Remove rear wheel grease cap.

Wear/slot Forming Checking for Bent Blades To ensure a superior quality of cut, keep the blades sharp. For convenient sharpening and replacement, you may want to keep extra blades on hand. 1. Rotate the blades until the ends face forward and backward (Fig. 45). Measure from a level surface to the cutting edge, position A, of the blades (Fig. 46).
1/8 inch (3 mm), the blade is bent and must be replaced. Refer to Removing the Blades and Installing the Blades on page 35. 1 Warning m–1854 A blade that is bent or damaged could break apart and could seriously injure or kill you or bystanders. Figure 48 1. Sharpen at original angle • Always replace bent or damaged blade with a new blade. • Never file or create sharp notches in the edges or surfaces of blade. 2. Check the balance of the blade by putting it on a blade balancer (Fig. 49).
5. Set the height-of-cut to the 4 inch (101.6 mm) position. Refer to Adjusting the Height-Of-Cut in the Operation section. Checking Engine Deck Height 6. Perform steps in the following sections Frame Set Up, Checking Front–to–Rear Pitch and Checking Side–to–Side Leveling. 2. Stop the engine, remove the key, and wait for all moving parts to stop before leaving the operating position. 1. Disengage the PTO and set the parking brake. 3. Adjust the tire pressure in all tires to specifications on page 31.
5 3 Checking the Deck Front-to-Rear Pitch 24 inch (61cm) 1. Check the tire pressure on both deck and traction unit. 2. Position one blade front-to-rear (Fig. 54). Measure at C and D locations (Fig. 54) from a level surface to the cutting edge of the blade tips (Fig. 55). 5 A B 2 4 4 3. The mower blade should be 1/4 inch (6 mm) lower in front at C than in the rear at D. Rotate blades and repeat for other blades. If it is not correct, proceed to Changing the Deck Front–to–Rear Pitch.

Caster Wheel and Bearings Service Replacing the Grass Deflector Warning The caster wheels rotate on a roller bearing supported by a spanner bushing. If the bearing is kept well lubricated, wear will be minimal. Failure to keep the bearing well lubricated will cause rapid wear. A wobbly caster wheel usually indicates a worn bearing. An uncovered discharge opening could allow the lawn mower to throw objects in the operator’s or bystander’s direction and result in serious injury.
