Operation
Note: Determine the left and right sides of the machine
from the normal operating position.
Daily Adjustments of Cutting
Unit
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.
Important Light contact is preferred at all times. If
light contact is not maintained, the 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 along 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 the cutting edge of the bedknife to
ensure smooth operation.
Maintenance
Note: Determine the left and right sides of the machine
from the normal operating position.
Greasing the Bearings and
Bushings
Each cutting unit has 6 grease fittings that must be
lubricated regularly with No. 2 General Purpose Lithium
Base Grease.
The grease fitting locations and quantities are:
• Reel bearings (2) (Fig. 6)
• Front and rear rollers (2 ea.) (Fig. 6)
Important Lubricating the cutting units immediately
after washing helps purge water out of the bearings and
increases bearing life.
1. Wipe each grease fitting with a clean rag.
2. Grease the reel bearings (Fig. 6) until grease comes out
of the pressure relief.
3. Grease the front and rear roller bearings (Fig. 6) until
grease begins to show around the seal lips.
Important Do not apply too much pressure or the
grease seals will be permanently damaged.
4. Wipe excess grease away.

Backlapping the Cutting Units
Contact with the reels or other moving parts can
result in personal injury.
Keep fingers, hands, and clothing away from the
reels or other moving parts.
Caution
1. Position the machine on a clean, level surface, lower the
cutting units, stop the engine, engage the parking brake,
and remove the ignition key.
2. Remove the reel motors from the cutting units and
disconnect and remove the cutting units from the lift
arms.
3. Connect the backlapping machine to the cutting unit by
inserting a piece of 3/8 in. square stock into the splined
coupling at the right end of the cutting unit.
Note: Additional instructions and procedures on
Backlapping are available in the Toro Sharpening Reel &
Rotary Mowers Manual, Form No. 80-300PT.
Note: For a better cutting edge, run a file across the front
face of the bedknife when the lapping operation is
completed. This will remove any burrs or rough edges that
may have built up on the cutting edge.
