Snapper 2 Series - Blade Brake Adjustment; Cutting Blade Service

SERVICE (Continued)
MOWER SERVICE & ADJUSTMENTS
Keep the topside of the mower free of grass cuttings.
Buiidup of clippings could cause belt problems and also
might present potential fire hazard especially when dry.
If uneven cutting is noted, check the tire pressure first
as this is the most common cause. If tire pressure is
correct and uneven cutting persists, move the tractor
to a flat level surface, such as a garage floor, and check
the deck level. (See “LEVELING MOWER”, Page 12).
To prolong the life and efficiency of your mower, keep
the underside of deck clean and free of accumulated
grass clippings by washing it down with a hose and/or
scraping with a wire brush and scraper. Make sure this
is done at the end of the cutting season before placing
the mower in storage.
BLADE BRAKE ADJUSTMENT
The BLADE BRAKE assembly is designed to stop blade
rotation within 3 seconds after the BLADE CONTROL
LEVER has been pushed downward to “OFF”. Should
the blades not stop within 3 seconds, the BLADE BRAKE
must be adjusted as follows:
1. Lower deck to lowest position.
2. Push BLADE CONTROL lever downward to “OFF”
position.
3. Loosen retaining nut on R.H. OUTSIDE PULLEY
BELT COVER and swing cover out of way.
4. Inspect BRAKE BAND closely to determine
approximate amount of adjustment required.
5. Tighten BRAKE BAND by loosening jam nut and
turning T-nut on end of eyebolt, clockwise 1 to 2
turns, or until BRAKE BAND tightens. Make sure
flanged lip on T-nut is positioned vertically to fit over
top edge of anchor. See Figure 22.

NOTE
MAKE SURE THAT BRAKE BAND DOES
NOT DRAG /^i^TER ADJUSTMENT.
6. A fter adjusting BLADE BRAKE, start mower,
engage blade and then disengage blade to
check stopping time. Readjust if necessary.
CUTTING BLADE SERVICE
Check at frequent intervals to make sure the blade is
securely tightened and that it is in good condition.
Replace blade if badly chipped, bent, out of balance,
or as soon as notch starts wearing in the tip between
the flat surface and upturned lift as depicted in Figure
23. This type wear pattern occurs more rapidly under
sandy soil conditions.
CAUTION
NEVER OPERATE THE MOWER WITH BLADE
WORN TO THE EXTENT SHOWN IN VIEW C AS
THE TIP COULD FLY OFF CAUSING PERSONAL
INJURY OR PROPERTY DAMAGE.
Sharpen blade when the cutting edges become dull if
the blade is in otherwise good condition. When dull,
the cut grass ends will be ragged and usually turn
brown soon after mowing. For best results, remove
the blade and sharpen it on a grinding wheel at an angle
of 22 to 28 degrees. The cutting surface should extend
in about 2 1/2" from the tips. Check the blade after
sharpening to determine that it is still balanced. It will
cause excessive vibration if unbalanced. See Figure 24.
