Maintenance
Cutting Unit Daily Adjustments
Prior to mowing each day, or as required, each cutting unit
must be checked to verify proper bedknife–to–reel
contact. This must be performed even though quality of
cut is acceptable.
1. Lower cutting units onto a hard surface, shut off
engine and remove key from ignition.
2. Slowly rotate reel in reverse direction listening for
reel-to-bedknife contact. If no contact is evident, move
the bedknife closer to the reel by loosening bottom
screw on each side of cutting unit, then tightening the
top adjustment screw on each side of cutting unit until
light contact is felt and heard.
Important Light contact is preferred at all times. If
light contact is not maintained, bedknife/reel edges will
not sufficiently self-sharpen and dull cutting edges will
result after a period of operation. If excessive contact is
maintained, bedknife/reel wear will be accelerated,
uneven wear can result, and quality of cut may be
adversely affected.
Note: As the reel blades continue to run against the
bedknife a slight burr will appear on the front cutting edge
surface the full length of the bedknife. If a file is
occasionally run across the front edge to remove this burr,
improved cutting can be obtained.
After extended running, a ridge will eventually develop at
both ends of the bedknife. These notches must be rounded
off or filed flush with cutting edge of bedknife. Also,
maintaining a lead–in chamfer (Fig. 16), on right end of
bedknife, will ensure smooth operation of the bedknife
and reel.
Note: The chamfer from the factory should last
approximately half the life of the bedknife.

Note: Do not make lead–in chamfer too large as it may
cause turf tufting.
Important The reel motors must be removed before
removing the cutting units to prevent hose damage due to
twisting, bending, and kinking.
Lubrication
There are 6 grease fittings on each cutting unit (Fig. 17)
which must be lubricated using a No. 2 multi-purpose
lithium base grease. A hand operated grease gun is
recommended for best results.
Important Toro recommends lubricating the cutting
unit immediately after washing to purge water out of the
bearings to increase bearing life.
1. Wipe each grease fitting with a clean rag.
2. Grease the (2) reel bearings until grease comes out the
weep hole.
3. Apply grease to the (2) front and (2) rear roller
bearings until clean grease comes out seals.
4. Wipe excess grease away.

Backlapping the Cutting Units
Danger
The reels may stall while backlapping.
• Do not attempt to restart the reels by hand or
adjust them while backlapping.
• Set the speed control to position 11 to start the
reels; set them to position 1 for backlapping.
Note: Backlap either the front cutting units together or the
rear ones together.
