Adjusting the Compression Spring

RANSPORT
position.
2. Check the distance between the 2 large washers, it
needs to be 28.2 cm (11–1/8 inches) for 52-inch
mower decks and 26.7 cm (10–1/2 inches) for 60-inch
mower decks (
Figure 83 ).
3. To adjust this distance, loosen the spring jam nut
and turn the nut in front of each spring (
Figure

counter-clockwise to lengthen the spring.
4. Lock the nut into position by tightening the spring jam

Servicing the Cutting Blades
Maintain sharp blades throughout the cutting season because
sharp blades cut cleanly without tearing or shredding the grass
blades. Tearing and shredding turns grass brown at the edges,
which slows growth and increases the chance of disease.
Check the cutter blades daily for sharpness, and for any
wear or damage. File down any nicks and sharpen the
blades as necessary. If a blade is damaged or worn, replace
it immediately with a genuine Toro replacement blade. For
convenient sharpening and replacement, you may want to
keep extra blades on hand.
DANGER
A worn or damaged blade can break, and a piece
of the blade could be thrown at you or bystanders,
resulting in serious personal injury or death.
• Inspect the blade periodically for wear or
damage.
• Replace a worn or damaged blade.
Before Inspecting or Servicing the
Blades
Park the machine on a level surface, disengage the blade
control (PTO), set the parking brake, turn the ignition key to
the O
FF
position, and remove the key.
Inspecting the Blades
Service Interval: Before each use or daily
1. Inspect the cutting edges ( Figure 84 ). If the edges
are not sharp or have nicks, remove and sharpen the
blades. Refer to
(page ) .
2. Inspect the blades, especially the curved area ( Figure
84 ). If you notice any damage, wear, or a slot forming
in this area ( Figure 84 ), immediately install a new blade.

position, and set the parking brake.
2. Shut off the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position.
3. Rotate the blades until the ends face forward and
backward (
Figure 85 ). Measure from a level surface to
the cutting edge, position A , of the blades ( Figure 85 ).
