3. Sharpen both ends of blade at original angle (25o),
removing equal amounts of material from each end
to maintain proper blade balance. New blades are
balanced to within 1.3 in. oz. at factory. DO NOT
grind around corner at tip of blade. If cutting edge
of blade cannot be sharpened in a straight line to
within 1/8 of an inch of its end, replace blade with
Ariens replacement blade only.
4. Install blade, lock washer, and tighten hardware to
torque listed above.
IMPORTANT: If mower is used under sandy soil
conditions, replace blades when air lifts become
eroded.
IMPORTANT: On 28" & 32", when replacing blade,
blade should be 3/8" (9.6 mm) above flange. To
position, turn cap screws on each end of blade tray
until both tips of blade clear flange by 3/8" (9.6 mm) all
the way around pan.

6.5 LINKAGES FOR MOWER HEIGHT/ENGAGEMENT & CLUTCH/BRAKE
NOTE: A wood block (about 1" square by 5" long) may
be used under pan for blade measurement. Wrap block
with masking tape, mark tape with cutting edge of
blade and measure distance from end of block to
mark(s). (This method avoids errors by having to read
any measurements under pan.)
