4. Measure the right blade at the B location, from
a level surface to the cutting edge of the blade
tip (Figure 78).
5. Record this measurement.
6. The mower blade should be a 1/4 to 3/8 inch
(6 to 10 mm) lower at position A than at
position B (Figure 78). If it is not correct,
proceed to the following steps.
Note: Both of the front swivels need to be
adjusted the same amount to maintain equal
chain tension.
7. Loosen the front swivel jam nuts, at the front
of the right and left swivels, approximately a
1/2 inch (13 mm) (Figure 77).
8. Adjust the lift nuts on both the left and the
right side of the machine to achieve 1/4 to
3/8 inch (6 to 10 mm) lower in front at A than
in the rear at B (Figure 77).
9. Tighten both swivel jam nuts against the front
swivel to lock the height.
10. Check to make sure there is equal tension on
the chains and adjust again if needed.
Adjusting the Compression Spring
1. Raise the mower lift lever to the transport
position.
2. Check the distance between the two large
washers, it needs to be 11-1/2 inches (29.2 cm)
(Figure 79).
3. Adjust this distance, by loosening the spring
jam nut and turning the nut in front of each
spring (Figure 79). Turning the nut clockwise
will shorten the spring; counter-clockwise will
lengthen the spring.
4. Lock the nut into position by tightening the
spring jam nut (Figure 79).

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.
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.
• Replace a worn or damaged blade.
Inspect and check the blades every 8 hours.
