Introduction Safety 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. This machine meets or exceeds the B71.4 1999 specifications of the American National Standards Institute, in effect at time of production.
• 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.
Toro Mower Safety DO • Remove obstacles such as rocks, tree limbs, etc. from the mowing area. Watch for holes, ruts or bumps. Tall grass can hide obstacles. The following list contains safety information specific to Toro products and other safety information you must know. • Use slow speed so that you will not have to stop while on the slope. This product is capable of amputating hands and feet and throwing objects. Always follow all safety instructions to avoid serious injury or death.
• Battery gases can explode. Keep cigarettes, sparks and flames away from battery. • Hydraulic fluid escaping under pressure can penetrate the skin and cause injury. Use cardboard or paper to find hydraulic leaks. Never use your hands.

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.

Thread rod fittings equal distance onto each control rod. For a starting point, thread fittings on approximately 1–3/4 in.
3. Check the gap between upper control bar and fixed bar with wheel drive fully engaged. Gap should be approximately 1 to 1-1/4 in. (25–32 mm) (Fig. 8). Note: Make sure brake rod is installed in front (“F”) mounting hole in idler bracket. 8. Repeat procedure on opposite side if adjustment is required to keep control bar and fixed bar parallel. Note: The upper control bar and fixed bar must be parallel when in engaged, drive, relaxed and brake positions. 4. Check operation.
Think Safety First Lower Control Bar – Shift transmission to reverse and squeeze the lower control bar and handle together to engage rearward traction operation. Carefully read all the safety instructions and decals in the safety section. Knowing this information could help you, your family, pets or bystanders avoid injury. Parking Brake Lever – Pull back on upper control bar and swing brake lever up against the upper handle.
Stopping 2. Lift the parking brake lock (Fig. 14) up and gradually release the upper control bar. The brake lock should stay in the set (locked) position. 1. Move the throttle lever to “SLOW” (Fig. 15). 2. Let engine idle for 30 to 60 seconds before turning the ignition key “OFF.” Releasing the Parking Brake 3. Turn the ignition key to “OFF” (Fig. 15). 1. Pull rearward on the upper control bar (Fig. 14). Lower the parking brake lock to the released position. 2 2.
2. Squeeze the blade control bail against upper control bar. The blades should not rotate. 2 1 3. Then continue holding the blade control bail and pull up on the blade control switch and release. The clutch should engage and the mower blades begin rotating. 3 4. Release the blade control bail. The blades should stop rotating. 5. With the engine running, pull up the blade control switch (PTO) and release without holding the blade control bail. The blades should not rotate.
3. Slowly squeeze the lower control bar and handle together to move rearward (Fig. 17). 1 Lower Control Bar Operation 2 This procedure is for driving up a curb. This can be performed while driving forward or backward. 1. Disengage the mower blades. Warning m–4185 A blade can be bent or damaged when driving up a curb. Pieces of blade that may be thrown could seriously injure or kill you or bystanders. Figure 19 1. Lower Control Bar engaged and mower in reverse.
Side Discharge or Mulch Grass Important All four hairpin cotter pins must be in the same hole location and with the correct number of spacers for a level cut. This mower has a hinged grass deflector that disperses clippings to the side and down toward the turf. Danger 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.

Slowly add additional oil to bring to “FULL” mark on dipstick. Service Interval/Specification Service Interval/Specification Check the spark plug(s) after every 100 operating hours. Make sure the air gap between the center and side electrodes is correct before installing the spark plug.
Where to Add Grease 2. Check the gap between the center and side electrodes (Fig. 29). Bend the side electrode (Fig. 29) if the gap is not correct. 2 Lubricate the grease fittings as shown on the CHECK SERVICE REFERENCE AID decal (Figure 30). 3 1 0.025 in. (0.65 mm) Figure 29 1. Center electrode insulator 2. Side electrode 3. Air gap (not to scale) Installing the Spark Plug(s) 1. Install the spark plug(s). Make sure the air gap is set correctly. Figure 30 2.
Lubricate the transmission couplers and linkage. This will help insure adequate cooling and correct engine speed and will reduce the possibility of overheating and mechanical damage to the engine. 1. Lubricate the transmission couplers located in the back of the machine (Fig. 32). Checking Tire Pressure Service Interval/Specification Maintain the air pressure in the front and rear tires as specified.
2. Release the parking brake; refer to Releasing the Parking Brake, page 18. 3. To adjust the brake remove the cotter pin and washer from the brake lever (Fig. 36). 4. Rotate the trunnion so it smoothly slides into brake lever hole “F” (Fig. 36). Tighten wing nut. 5. Secure trunnion to brake lever with washer and cotter pin (Fig. 36). 6. Check the brake operation again; refer to Checking the Brake, page 29.

dimension exceeds 1/8 in. (3 mm), the blade is bent and must be replaced. Refer to Removing the Blades, and Installing the Blades on page 32. 1 Warning m–1854 A blade that is bent or damaged could break apart and could seriously injure or kill you or bystanders. Figure 44 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.
5. Perform steps in the following sections Frame Set Up, Checking Front–to–Rear Pitch and Checking Side–to–Side Leveling. Checking Engine Deck Height Frame Set Up 2. Adjust the tire pressure in all tires to specifications on page 28. 1. Stop the engine, remove the key and disconnect the spark plug wire(s) from the spark plug(s). 3. Measure engine deck height at location “A” (Fig. 47). Checking Carrier Frame and Deck Alignment 4. Measure engine deck height at location “B” (Fig. 47). 5.

Checking the Deck Side-to-Side Leveling 1. Check the tire pressure on both deck and traction unit. MEASURE FROM CUT TINGEDGETOA LEVELSURFACE 2. Position the blades side-to-side (Fig. 53). Measure at “A” and “B” locations (Fig. 53) from a level surface to the cutting edge of blade tips (Fig. 54). m–1087 Figure 51 3. The difference between measurements “A” and “B” should be no more than 1/4” (6 mm).
Matching Height of Cut 1. Remove top capscrew securing idler support and idler bracket to rear frame (Fig. 57). 1. Check the tire pressure on both deck and traction unit. 2. Loosen bottom two mounting screws enough to allow belt to pass between drive pulley and idler support (Fig. 57). 2. Set the height-of-cut to the 4 in. (102 mm) position following the height-of-cut decal. 3. Raise wheel off ground enough to allow belt removal. 3.
