Maintenance and Storage
Toro Mower Safety
The following list contains safety information specific to
Toro products or other safety information that you must
know that is not included in the ANSI standards.
• Check the blade mounting bolts frequently to be sure
that they are tightened to specification.
• Make sure that all hydraulic line connectors are tight
and all hydraulic hoses and lines are in good condition
before applying pressure to the system.
4
Page 5
• Keep your body and hands away from pin hole leaks or
nozzles that eject hydraulic fluid under high pressure.
Use paper or cardboard, not your hands, to search for
leaks. Hydraulic fluid escaping under pressure can have
sufficient force to penetrate the skin and cause serious
injury.
• Before disconnecting or performing any work on the
hydraulic system, all pressure in the system must be
relieved by stopping the engine and lowering the cutting
units to the ground.
• If the engine must be running to perform a maintenance
adjustment, keep hands, feet, clothing, and any parts of
the body away from the cutting units, attachments, and
any moving parts. Keep everyone away.
• Do not overspeed the engine by changing governor
settings. To ensure safety and accuracy, have an
Authorized Toro Distributor check the maximum engine
speed with a tachometer.
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.
• The engine must be shut off before checking the oil or
adding oil to the crankcase.
• Make sure that the mower fuel tank is empty if the
machine is to be stored in excess of 30 days. Do not
store the mower near any open flame or where gasoline
fumes may be ignited by a spark.
• Perform only those maintenance instructions described
in this manual. If major repairs are ever needed or if
assistance is desired, contact an Authorized Toro
Distributor.
• To make sure of optimum performance and continued
safety certification of the machine, use only genuine
Toro replacement parts and accessories. Replacement
parts and accessories made by other manufacturers
could be dangerous, and such use could void the
product warranty.

102 mm) in 1/2 inch (13 mm) increments, by adding or
removing an equal number of spacers on the front and rear
castor forks. The height-of-cut chart below gives the
combinations of spacers to use for all height-of-cut settings.
Note: 1/4 inch (6 mm) spacers are available and can be
ordered from your Toro distributor by Part No. 27-1040.
(Quantity of 8).
Note: A more optimum cutting appearance of the turf can
be achieved in the lower heights-of-cut by lowering the rear
of the cutting unit. Accomplish this by relocating the rear
castor wheel axles in the upper hole of the caster forks
(Fig. 19). Place the axles into the lower castor fork holes
for higher height-of-cut settings where optimum cutting
appearance is not required.
Important Do not attempt to cut off more than 1 inch
(25 mm) of the grass blades in the 1 inch (25 mm)
height-of-cut setting with the rear of the cutting unit
lowered, as this may cause the engine to labor excessively.
1. Start the engine and raise the cutting unit so that the
front caster height-of-cut can be changed. Stop the
engine after the cutting unit is raised. The rear castor
height-of-cut can be changed with the cutting unit
lowered.
2. Remove the tensioning cap from the spindle shaft. Slide
the spacers onto the castor spindle to get the desired
height-of-cut (Fig. 18 and 19). Then slide the washer
(Fig. 18 and 19) onto the spindle.
3. Push the castor spindle through the castor arm. Slide
any remaining spacers onto the spindle (Fig. 18 and 19).
Install the tensioning cap to secure the assembly.
Note: When the cutting unit is used in the 1 in. (25 mm) or
1-1/2 in. (38 mm) height-of-cut setting, the front and rear
rollers must be positioned in the upper bracket holes.

rotating the cutter blades. Tighten the gear box
mounting fasteners.
7. Tension the idler pulleys against both belts. Install the
covers on top of the cutting unit.
Servicing the Bushings in the
Castor Arms
The castor arms have bushings pressed into the top and
bottom portion of the tube and after many hours of
operation, the bushings will wear. To check the bushings,
move the castor fork back and forth and from side-to-side.
If the caster spindle is loose inside the bushings, the
bushings are worn and must be replaced.
Figure 29
5. Apply grease to the inside and outside of the new
bushings. Using a hammer and flat plate, drive the
bushings into the mounting tube.
6. Inspect the castor spindle for wear and replace it if it is
damaged.
7. Push the castor spindle through the bushings and
mounting tube. Slide the spacers onto the spindle.
Install the tensioning cap onto the castor spindle to
retain all parts in place.
Servicing the Rear Castor
Wheel and Bearing
The rear castor wheels rotate on high-quality roller bearings
which are supported by spanner bushings. Even after many
hours of use, provided that the bearing was kept
well-lubricated, bearing wear will be minimal. However,
failure to keep the bearings lubricated will cause rapid
wear. A wobbly castor wheel usually indicates a worn
bearing.
1. Remove the capscrew and locknut holding the castor
wheel and 2 washers between the castor fork (Fig. 30).
2. Pull the spanner bushing out of the wheel hub (Fig. 30).

Removing the Cutting Blade
Inspecting and Sharpening the
The blade must be replaced if a solid object is hit, the blade
is out-of-balance, worn, or bent. Always use genuine Toro
replacement blades to ensure safety and optimum
performance. Never use blades made by other
manufacturers because they could be dangerous.
Danger
A worn or damaged blade can break, and a piece
of the blade could be thrown into the operator’s or
bystander’s area, resulting in serious personal
injury or death.
• Inspect the blade periodically for wear or
damage.
• Do not try to straighten a blade that is bent.
• Never weld a broken or cracked blade.
• Replace a worn or damaged blade with a new
Toro blade to ensure continued safety
certification of the product.
1. Raise the cutting unit to the highest position, shut the
engine off, and engage the parking brake. Block the
cutting unit to prevent it from accidentally falling.
Blade
1. Raise the cutting unit to the highest position, shut the
engine off, and engage the parking brake. Block the
cutting unit to prevent it from accidentally falling.
2. Examine the cutting ends of the blade carefully,
especially where the flat and curved parts of the blade
meet (Fig. 33-A). Since sand and abrasive material can
wear away the metal that connects the flat and curved
parts of the blade, check the blade before using the
machine. If wear is noticed (Fig. 33-B), replace the
blade; refer to Removing the Cutting Blade, page 21.
2. Grasp the end of the blade using a rag or thickly padded
glove. Remove the special screw, Belleville washer, and
blade from the spindle assembly (Fig. 32).
Figure 32
Note: The special screw has a left-hand thread.
3. To install the blade, assemble the parts in reverse order,
and make sure that the blade sail is facing up. Tighten
the special screw to 75 to 100 ft.-lb. (102 to 136 N⋅m).
Figure 33
Warning
If the blade is allowed to wear, a slot will form
between the sail and flat part of the blade
(Fig. 33-C). Eventually, a piece of the blade may
break off and be thrown from under the housing,
possibly resulting in serious injury to yourself or
bystanders.
• Inspect the blade periodically for wear or
damage.
• Replace a worn or damaged blade with a new
Toro blade to ensure continued safety
certification of the product.
3. Examine the cutting edges of all blades. Sharpen the
cutting edges if they are dull or nicked. Sharpen only
the top side of the cutting edge and maintain the
original cutting angle to ensure sharpness (Fig. 34). The
blade will remain balanced if the same amount of metal
is removed from both cutting edges.
21
Page 22
SHARPEN AT THIS
ANGLE ONLY
END VIEW
Figure 34
4. To check the blade for being straight and parallel, lay
the blade on a level surface and check the ends. The
ends of the blade must be slightly lower than the center,
and the cutting edge must be lower than the heel of the
blade. This blade will produce good a quality-of-cut and
require minimal power from the engine. By contrast, a
blade that is higher at the ends than the center, or the
cutting edge is higher than the heel of the blade, is
warped or bent and must be replaced.
5. To install the blade, assemble the parts in reverse order,
and make sure that the blade sail is facing up. Tighten
the special screw to 75–100 ft.-lb. (102 to 136 N⋅m).
6. Rotate the blades so that the tips line up with one
another. The tips of the adjacent blades must be within
1/8 inch (3 mm) of each other. If the tips are not within
1/8 inch (3 mm) of each other, proceed to step 7 and
add shims between the spindle housing and bottom of
the cutting unit.
7. Remove the capscrews, flat washers, lock washers, and
nuts from the outer spindle, in the area where the shims
must be added. To raise or lower the blade, add a shim,
Part No. 3256-24, between the spindle housing and
bottom of the cutting unit. Continue to check the
alignment of the blade and add shims until the tips of
the blades are within the required dimension.
Important Do not use more than 3 shims at any one
hole location. Use decreasing numbers of shims in adjacent
holes if more than one shim is added to any 1 hole location.
8. Tension the idler pulleys against all 3 belts. Also install
the covers to the top of the cutting unit.
9. Set the rear castor wheels in the lower holes in the
castor forks if the height-of-cut is above 1 inch (25 mm)
and adjust the height-of-cut.
Checking and Correcting
Mismatch of Blades
If there is mismatch between the blades, the grass will
appear streaked when it is cut. This problem can be
corrected by making sure that the blades are straight and all
blades are cutting on the same plane.
1. Using a 3 foot (1 m) long carpenters level, find a flat
surface on the shop floor.
2. Set the rear castor wheels in the upper hole of the castor
forks and adjust the height-of-cut so that all 6
height-of-cut spacers are below the castor arm.
3. Lower the cutting unit onto a flat surface. Remove the
covers from the top of the cutting unit. Loosen the idler
pulleys to release the tension against all 3 belts.
4. Rotate the blades until the ends face forward and
backward. Measure from the floor to the front tip of the
cutting edge and remember this dimension. Then rotate
the same blade so that opposite end is forward and
measure again. The difference between the dimensions
must not exceed 1/8 inch (3 mm). If the difference
exceeds 1/8 inch (3 mm), replace the blade because it is
bent. Make sure to measure all three blades.
10.Mount the cutting unit to the traction unit; refer to
Mounting the Cutting Unit to the Traction Unit,
page 18.
5. Compare the measurements of the outer blades with the
center blade. The center blade must not be more than
3/8 inch (10 mm) lower than the outer blades. If the
center blade is more than 3/8 inch (10 mm) lower than
the outer blades, proceed to step 7 and add shims
between the spindle housing and bottom of the cutting
unit.
