4. Use a good grade of medium grit (80) commercial
lapping compound with a water soluble carrier to
assure the compound will be easily washed away at the
completion of the backlapping operation. Dry lapping
compound should be mixed with liquid detergent
(soap) until the material is of free flowing consistency.

N m) drag on reel shaft. Rotate the shaft and
repeat check to be sure bearings are aligned in cup and
cone.
If bearings need adjustment, locate and remove lock
tab from lockwasher inserted into slot on locknut
(Fig. 38).
Note: Paste-type pre–mixed lapping compound is also
sold in some areas. This is generally used in its original
composition and therefore is not free flowing.

Operate the lapping machine so the reel turns in a
reverse direction for about three minutes. apply
lapping solution continuously with a paint brush across
the full width of the reel.

Adjust locknut in small increments and check for
proper preload. Bend ears of lockwasher into slots on
locknut when adjustment is completed to secure
locknut (Fig. 38).
7. Wash off all lapping solution.
8.
Using newspaper, check for sharpness along the entire
length of each reel blade. If the newspaper cannot be
cut cleanly along the entire length of each blade,
grinding or re–grinding is necessary; refer to Reel and
Bedknife Grinding.

Install left reel bracket.
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 burr or rough edge that
may have built up on the cutting edge.
Backlap Operation
Backlap when reel blades and bedknife edge are slightly
rounded and do not cut the grass cleanly with a light reel
to bedknife adjustment. Also backlap after a reel and
bedknife have been reground to establish a land area and
assure a perfect match between reel and bedknife cutting
edge. Backlapping will not correct nicked or severely
rounded reel blades or uneven bedknife wear. Correct
these conditions by repairing, replacing or re–grinding the
components.
Reel And Bedknife Grinding
Refer to the TORO GUIDE TO REEL AND ROTARY
MOWER SHARPENING. Copies are available from your
local Toro distributor.
Note: In order to grind the bedknife, it has to be removed
from the cutting unit. The bedknife is then mounted on the
grinding bar (TOR 31397).
1.
Using a fine–tooth file, remove high spots from reel
blades. If any blade is bent, straighten by placing a
hammer on one side of blade and tapping on opposite
side.
Cleaning Mower
It is recommended to wash the cutting unit, transaxle, and
grass basket after each day’s use. Chemicals in the turf
may cause premature deterioration to certain components
if not washed daily.

3.
Adjust the reel to bedknife to obtain a light contact;
refer to Reel to Bedknife Adjustment.
Connect a lapping machine to the cutting unit with an
extension coupler, and socket.
Important
Do not direct “high–pressure” water at oil
seals, bearings, electrical connectors/switches, hot engine,
etc.; contamination of these parts could cause premature
wear.
