Setting Height Of Cut - Toro 03857 Operator's Manual

Setting Height of Cut

IMPORTANT. To insure proper setting of height of
cut, these procedures must be followed in this order:
A. Adjusting (Parallel) the bedknife to the reel
B. Setting cutting unit attitude
C. Leveling the front roller
D. Finalizing height of cut
IMPORTANT: Each cutting unit must be set
consistently. Minor differences in either 1) height of
cut, 2) attitude, 3) bedknife wear or 4) Reel blade
wear, between cutting units, may result in negative
after-cut appearance.
NOTE: The cutting unit has been set at the factory at
1.59 cm (5/8") height of cut and with a cutting unit
attitude of 2 degrees. Also, the bedknife has been
retracted from the reel to prevent shipping damage.
Verity the setting to ensure changes did not occur during
shipment.
A. ADJUSTING (PARALLEL) THE BEDKNIFE
TO THE REEL
IMPORTANT. The reel and bedknife must be
parallel to an even cut of grass, and that the reel and
bedknife wear evenly.
NOTE: Toro recommends light contact between the reel
and bedknife. However, for dry and/or sparse conditions
a .001–.002" (.03–05 mm) clearance may be required to
prevent heat buildup, which can cause uneven wear in
the reel and bedknife.
NOTE: A 3/4-inch (19 mm) wrench is needed to rotate
the bedknife adjustment knob. Each notch on the knob
will move the bedknife 0.0005 inches (.013 mm) closer
to the reel (Fig. 6).
1. Rotate the cutting unit backward to gain access to
reel and bedknife (Fig. 7).
2. While slowly rotating the reel in the mowing
direction, turn the bedknife adjusting knob
clockwise until you hear light contact between the
reel and bedknife.
1. Bedknife adjusting knob
3. Insert a 3-cm wide piece of newspaper
perpendicular to the bedknife, and then turn the reel
slowly in the mowing direction to see if the reel
cuts the paperódo this on both ends of the bedknife
(Fig. 7).
4. If paper is cut on both ends, the bedknife is parallel
to the reel. If not go to steps 5 through 8.
NOTE: If the reel makes contact on both sides of
the bedknife but still does not cut paper, the cutting
unit may need to be backlapped (refer to
Backlapping) and/or reel and bedknife may need to
be reground (refer to Toro manual for Sharpening
Reel and Rotary Mowers, Form No. 80-30OPT).
