any moving parts while engine is running.
Mow only in daylight or good artificial light.
Watch for traffic when operating near or crossing
roadways.
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. Warranty may
be voided if used with unapproved attachments.
Slope Operation
Slopes and ramps are a major factor related to loss-of-control and accidents, which can result in severe injury or death. All slopes and ramps require extra caution. If you feel uneasy on a slope, do not mow it.
Mow slopes side–to–side.
DO NOT
Do not mow slopes greater than 15 degrees.
Avoid turning on slopes. If you must turn, turn slowly
and gradually downhill, if possible.
Do not mow near drop-offs, ditches, or embankments.
The machine could suddenly turn over if a wheel goes over the edge of a cliff or ditch, or if an edge caves in.
Do not mow on wet grass. Reduced traction could
cause sliding.
Do not use a grass catcher on steep slopes. Heavy
grass bags could cause loss of control, of the machine.
Do not mow up and down slopes.
Service
Never store the machine or fuel container inside where
there is an open flame, such as near a water heater or furnace.
Keep nuts and bolts tight, especially the blade
attachment bolts.
Never tamper with safety devices. Check safety
systems for proper operation before each use.
Use only Toro genuine replacement parts to ensure that
original standards are maintained.
Hydraulic fluid escaping under pressure can penetrate
the skin and cause injury. Use cardboard or paper to find hydraulic leaks. Never use your hands.
DO
Watch for holes, ruts or bumps. Tall grass can hide
obstacles.
Use slow speed so that you will not have to stop while
on the slope.
Use extra care with grass catchers or other
attachments. These can change the stability of the
machine.
Keep all movement on slopes slow and gradual. Do
not make sudden changes in speed or direction.
Avoid starting or stopping on a slope. If tires lose
traction, disengage the blades.

Gasoline and Oil
Recommended Gasoline
Use UNLEADED Regular Gasoline suitable for automotive use (85 pump octane minimum). Leaded regular gasoline may be used if unleaded regular is not available.
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.
Danger
In certain conditions, gasoline is extremely flammable and highly explosive. A fire or explosion from gasoline can burn you and others and can damage property.
Fill the fuel tank outdoors, in an open area,
when the engine is cold. Wipe up any gasoline that spills.
Do not fill the fuel tank completely full. Add
gasoline to the fuel tank until the level is 1/4 in. to 1/2 in. (6 mm to 13 mm) below the bottom of the filler neck. This empty space in the tank allows gasoline to expand.
Never smoke when handling gasoline, and stay
away from an open flame or where gasoline fumes may be ignited by a spark.
Store gasoline in an approved container and
keep it out of the reach of children. Never buy more than a 30-day supply of gasoline.
Always place gasoline containers on the ground
away from your vehicle before filling.
Do not fill gasoline containers inside a vehicle
or on a truck or trailer bed because interior carpets or plastic truck bed liners may insulate the container and slow the loss of any static charge.
When practical, remove gas–powered
equipment from the truck or trailer and refuel the equipment with its wheels on the ground.
If this is not possible, then refuel such
equipment on a truck or trailer from a portable container, rather than from a gasoline dispenser nozzle.
If a gasoline dispenser nozzle must be used,
keep the nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete.
Warning
Gasoline is harmful or fatal if swallowed. Long–term exposure to vapors can cause serious injury and illness.
Avoid prolonged breathing of vapors.
Keep face away from nozzle and gas tank or
conditioner opening.
Keep gas away from eyes and skin.
Using Stabilizer/Conditioner
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.
Filling the Fuel Tank
1. Shut the engine off and set the parking brake.
2. Clean around fuel tank cap and remove the cap. Add
unleaded regular gasoline to fuel tank, until the level is 1/4 to 1/2 inch below the bottom of the filler neck. This space in the tank allows gasoline to expand. Do not fill the fuel tank completely full.
3. Install fuel tank cap securely. Wipe up any gasoline
that may have spilled.
Check Engine Oil Level
Before you start the engine and use the machine, check the oil level in the engine crankcase; refer to Checking Oil Level, page 26.

4. Check hydraulic fluid level as it drops and add as
required to maintain proper level.
5. Repeat procedure on opposite wheel.
Check Hydraulic Lines
After every 100 operating hours, check hydraulic lines and hoses for leaks, loose fittings, kinked lines, loose mounting supports, wear, weather and chemical deterioration. Make necessary repairs before operating.
Note: Keep areas around hydraulic system clean from grass and debris build up.
Warning
Hydraulic fluid escaping under pressure can penetrate skin and cause injury.
If hydraulic fluid is injected into the skin it
must be surgically removed within a few hours by a doctor familiar with this type of injury. Gangrene may result if this is not done.
Keep body and hands away from pin hole leaks
or nozzles that eject high pressure hydraulic fluid.
Use cardboard or paper to find hydraulic leaks.
Safely relieve all pressure in the hydraulic
system before performing any work on the hydraulic system.
Make sure all hydraulic fluid hoses and lines
are in good condition and all hydraulic connections and fittings are tight before applying pressure to hydraulic system.
9. Start engine and let run for about two minutes to purge
air from the system. Stop the engine and check for leaks. If one or both wheels will not drive, refer Bleeding Hydraulic System, page 32.
10.Recheck level while fluid is warm. Add fluid to raise level to top of the baffle, if required. Do not overfill.
Adjusting By-pass Valve
The by–pass valve is adjustable to ensure easy operation with a variety of deck sizes. If the front of the deck lifts off the ground when the upper control bar is quickly pushed forward or the machine is unable to drive up hills, an adjustment may be needed.
32
Test Procedure
1. Start engine and run for 5 minutes at 3/4 throttle, to
warm hydraulic fluid.
2. Drive the machine to a clear and level open area such
as a driveway.
Important There should be at least 10 feet of clear
area in front of the machine.
3. Loosen the quick release levers and push the reference
bar forward to the “FAST” position. Lock the quick release levers to secure the reference bar.
4. Move throttle control to 3/4 throttle.
5. Quickly push the upper control bar against the
reference bar. The front caster wheels should almost lift off the ground. If front caster wheels lift the off the ground , the machine is too aggressive and adjustment is required.
Important By–pass valve adjustment is very sensitive,
do not adjust more than 1/6 turn (one flat) at a time.
6. If the machine is too aggressive or tends to jump
forward, the valve needs to be opened further.
7. If the machine is slow to respond, the valve needs to
be closed further.
8. Repeat “Test Procedure” to check for proper operation.
Re-adjust the by–pass valves until proper performance is achieved.
2
6. Move the engine throttle to the “FAST” position.
7. Quickly push the upper control bar against the
reference bar. The front caster wheels should lift approximately 1 inch off the ground. If front caster wheels lift the off the ground more than 2 inches, the machine is too aggressive. Adjustment is required.
8. If the machine accelerates slowly, and the front caster
wheels do not lift off the ground, the machine is too un–responsive. Adjustment is required.
Adjustment Procedure
The by–pass valve should be adjusted to deliver best performance for the size (weight) mower you have.
The following values can be used as initial settings for different size mowers: 52 in. (132 cm) 1/2 turn out 44 in. (112 cm) 1 turn out 36 in. (91 cm) 1–1/6 turn out
1. Loosen large jam nut several turns (Fig. 35).

Replacing the Caster Wheel Fork Bushings
The caster wheel forks are mounted in bushings pressed into the top and bottom of the carrier frame mounting tubes. To check the bushings, move the caster forks back and forth and side-to-side. If a caster fork is loose, the bushings are worn and must be replaced.
1. Raise the cutting unit so the caster wheels are off the
floor, then block up the front of the mower with jack stands.
2. Remove the locking pin and spacer(s) from the top of
the caster wheel fork (Fig. 66).
3. Pull the caster wheel fork out of the mounting tube,
leaving the spacer(s) on the bottom of the fork. Remember the location of the spacers on each fork to ensure correct installation, and to maintain a level deck.

Caster Wheel and Bearings Service
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. Remove the locknut and wheel bolt holding the caster wheel to the caster fork (Fig. 68).
2. Remove one bushing, then pull the spanner bushing and roller bearing out of the wheel hub (Fig. 68).
3. Remove the other bushing from the wheel hub and clean any grease and dirt from the wheel hub (Fig. 68).
4. Inspect the roller bearing, bushings, spanner bushing and inside of the wheel hub for wear. Replace any defective or worn parts (Fig. 68).
8. Grease the fitting on the carrier frame mounting tube
using No. 2 general purpose lithium base or molybdenum base grease.
