• Wear appropriate clothing including hard hat, safety glasses and hearing protection. Long hair, loose clothing or jewelry may get tangled in moving parts. • Stop equipment and inspect blades after striking objects or if an abnormal vibration occurs. Make necessary repairs before resuming operations. • Inspect the area where the equipment is to be used and remove all objects such as rocks, toys and wire which can be thrown by the machine. • Keep hands and feet away from the cutting unit.
Toro Mower Safety DO • Remove obstacles such as rocks, tree limbs, etc. from the mowing area. The following list contains safety information specific to Toro products and other safety information you must know. • Watch for holes, ruts or bumps. Tall grass can hide obstacles. This product is capable of amputating hands and feet and throwing objects. Always follow all safety instructions to avoid serious injury or death. • Use slow speed so that you will not have to stop while on the slope.
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.

Nut Warning With the weight installed in the rear position, the front end of the machine can rapidly raise up when the mower is removed. This could cause serious injury to you or bystanders. • Support the rear of the machine when removing the mower from the carrier frame.
Operation Upper Control Bar – Shift to desired gear and push forward on control bar to engage forward traction operation and pull back to brake forward movement. Pull back on right side of control bar to turn right and left side to turn left. Note: Determine the left and right sides of the machine from the normal operating position. Lower Control Bar – Shift transmission to reverse and squeeze the lower control bar and handle together to engage rearward traction assist operation.
Using the Parking Brake 4. Grasp recoil starter handle firmly and pull out until positive engagement results; then pull handle vigorously to start engine and allow rope to recoil slowly. Stop on level ground, disengage drives, engage parking brake, shut off engine and remove key. Always set the parking brake when you stop the machine or leave it unattended.
• The blade control switch (PTO) is pulled on. 3. Pull blade switch (PTO) up and release. Hold blade control bail against control bar while operating. The safety interlock system is designed to stop the mower blades if you release the blade control bail. 4. Repeat procedure to engage mower blades if blade control bail is released. Testing the Safety Interlock System 2 1 Test the safety interlock system before you use the machine each time.
5. Drive machine until drive wheels contact curb (Fig. 21). 1 6. Lower the front of the machine (Fig. 21). Note: Both drive wheels should contact the curb and caster wheels straight. 2 7.

Adjusting the Height-of-Cut Caution Children or bystanders may be injured if they move or attempt to operate the machine while it is unattended. The height-of-cut can be adjusted from 1 to 4-1/2 inch (25 to 114 mm) in 1/4 inch (6 mm) increments. Adjustment is done by relocating four hairpin cotter pins in different hole location and by adding or removing spacers. Always remove the ignition key and set the parking brake when leaving the machine unattended, even if just for a few minutes.
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 (Figures 23, 24, and 25). 3 2. If adjustment is needed, remove the bolt, washer(s) and nut (Figures 23, 24, and 25). 4 3. Select a hole position so the gage wheels are a minimum of 3/8 inch (10 mm) off the ground (Figures 23, 24, and 25). 4. Install the bolt, washer(s) and nut (Figures 23, 24, and 25). 1 4 1 2 m–6510 Figure 25 1. Center Gage Wheels and Spacer 2. Nut 3.

Maintenance Note: Determine the left and right sides of the machine from the normal operating position.
Servicing the Air Cleaner Service Interval/Specification Note: Excess oil in the foam element restricts the air flow through the element and may reach the paper filter and clog it. Foam Element: Clean and re-oil after every 25 operating hours. Important worn. Replace the foam element if it is torn or Paper Element: Replace after every 100 operating hours. 2 Inspect the foam and paper elements, and replace them if they are damaged or excessively dirty.
3. Install the air cleaner cover and secure with cover nuts (Fig. 29). 1 2 Servicing the Engine Oil 3 Service Interval/Specification Change oil: • After the first 8 operating hours. • After every 100 operating hours. Note: Change oil more frequently when operating conditions are extremely dusty or sandy. Figure 32 1. Oil dipstick 2. Metal end Oil Type: Detergent oil (API service SF, SG or SH) 3. Filler tube Crankcase Capacity: w/filter, 64 oz. (1.
7. Slowly pour approximately 80% of the specified oil into the filler cap (Fig. 32). Refer to Servicing the Engine Oil, page 29. Servicing the Spark Plug 8. Check the oil level; refer to Checking the Oil Level, page 29. 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.
Lubricating the Caster and Wheel Bearings 2. Check the gap between the center and side electrodes (Fig. 36). Bend the side electrode (Fig. 36) if the gap is not correct. 2 1. Lubricate the front wheel bearings and front spindles until grease begins to ooze out of the bearings (Fig. 37). 3 1 2. Raise the rear of the machine and use jack stands to support the machine. 0.040 in. (1.02 mm) 3. Remove the rear wheel and tire assembly. 4. Remove rear wheel grease cap.

Wear/slot Forming Checking for Bent Blades Servicing the Cutting Blades 1. Rotate the blades until the ends face forward and backward (Fig. 47). Measure from a level surface to the cutting edge, position A, of the blades (Fig. 48). Note this dimension. To ensure a superior quality of cut, keep the blades sharp.
1/8 inch (3 mm), the blade is bent and must be replaced. Refer to Removing the Blades and Installing the Blades. 1 Warning m–1854 A blade that is bent or damaged could break apart and could seriously injure or kill you or bystanders. Figure 50 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. 51).
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 32.
5 3 Checking the Deck Front-to-Rear Pitch 24 in. (61cm) 1. Check the tire pressure on both deck and traction unit. 2. Position one blade front-to-rear (Fig. 56). Measure at C and D locations (Fig. 56) from a level surface to the cutting edge of the blade tips (Fig. 57). 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 2 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. 1 1. Remove the locknut and wheel bolt holding the caster wheel to the caster fork (Fig. 69). 3 2. Remove one bushing, then pull the spanner bushing and roller bearing out of the wheel hub (Fig. 69). 3.
4 Replacing the Grass Deflector 2 8 Warning 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. Also, contact with the blade could occur. Never operate the lawn mower unless you install a cover plate, a mulch plate, or a grass chute and catcher. 6 3 1 1. Remove the locknut, bolt, spring and spacer holding the deflector to the pivot brackets (Fig. 70). Remove damaged or worn grass deflector. 5 2.
