Maintenance
Note:
Determine the left and right sides of the
machine from the normal operating position.
Supporting the Cutting Unit
Whenever you need to tip the cutting unit to expose
the bedknife/reel, prop up the rear of the cutting unit
to ensure that the nuts on the back end of the bedbar
adjusting screws are not resting on the work surface
(Figure
8).

Adjusting the
Bedknife-to-Reel Contact
Adjusting the Bedknife Daily
Prior to mowing each day, or as required, verify proper
bedknife-to-reel contact. Perform this procedure
even though quality of cut is acceptable.
1.
Lower the cutting units onto a hard surface, shut
off the engine, and remove the ignition key.
2.
Slowly rotate the reel in a reverse direction,
listening for reel-to-bedknife contact.
•
If no contact is evident, adjust the bedknife
as follows
A.
Turn the bedbar adjusting screws
clockwise
until you feel and hear light contact.
Note:
The bedbar adjusting screws
have detents corresponding to 0.018
mm (0.0007 inch) bedknife movement
for each indexed position.

Insert a long strip of cutting performance
paper (Toro Part No. 125-5610) between
the reel and bedknife, perpendicular to
the bedknife
rotate the reel forward; it should cut the
paper; if not, repeat steps
it does.

•
If excessive contact/reel drag is evident,
backlap, reface the front of the bedknife, or
grind the cutting unit to achieve the sharp
edges needed for precision cutting (Refer to
the Toro Manual for Sharpening Reel and
Rotary Mowers, Form No. 09168SL).
Important:
times. If you do not maintain light contact,
the bedknife/reel edges will not sufficiently
self-sharpen, and dull cutting edges will
result after a period of operation. If you
maintain excessive contact, bedknife/reel
wear will be accelerated, uneven wear can
result, and the quality of cut may decline.
Note:
As the reel blades continue to run against
the bedknife, a slight burr will appear on the front
cutting edge surface along the full length of the
bedknife. Occasionally run a file across the front
edge to remove this burr to improve cutting.
After extended running, a ridge will eventually
develop at both ends of the bedknife. Round
off these notches or file them flush with the
cutting edge of the bedknife to ensure smooth
operation.
