Setting Cutting Unit Attitude - New Cutting Units - Toro Reelmaster 6500–D Service Manual

B. Setting Cutting Unit Attitude – New Cutting Units
IMPORTANT: Cutting unit "attitude" has a significant im-
pact on the performance of the cutting unit. Attitude re-
fers to the angle of the knife relative to the ground (Fig.
12). Adjustable front and rear brackets allow for variable
adjustment of cutting unit attitude within the height–of–
cut range. All cutting units on a given machine must be
set to the same attitude, if not - after cut appearance will
be negatively affected.
The best cutting unit attitude is dependent on your turf
conditions and desired results. Experience with the cut-
ting unit on your turf will determine the best setting to
use. Cutting unit attitude can be adjusted throughout the
cutting season to allow for various turf conditions.
In general, less aggressive attitudes (example: 2 de-
grees) are more appropriate for warm season grasses
while cool season grasses may require more aggres-
sive attitudes (example: 6 degrees). More aggressive
attitudes cut more grass off by allowing the spinning reel
to pull more grass up into the bedknife. An angle that is
too flat (attitude less than 1 degree) may allow the bed-
bar or other parts of the cutting unit to drag in the turf
causing tufting. Therefore, minimum recommended atti-
tude is 1 degree.
For setting consistent cutting unit attitude, Toro strongly
recommends using a two–screw gauge bar, Toro part
no. 98–1852 (Fig. 13). The first screw is set for height–
of–cut, and the second screw is set for cutting unit atti-
tude. The second screw setting is an easy method of
transferring cutting unit attitude to all cutting units on a
machine.
NOTE: The third hole is not used for RM6000 cutting
units.
SETTING ATTITUDE FOR NEW CUTTING UNITS:
Table 1 lists dimensions for setting up a new cutting unit
with attitudes of 2, 4, 6 and 8 degrees.
NOTE: The second screw setting will change through-
out the life of the bedknife and reel due to wear – even if
the height–of–cut is not changed. Therefore, after ini-
tial set up use Checking and Adjusting Attitude for
Used Cutting Unit procedure.
1. Using a two–screw gauge bar, Toro part no.
98–1852, set first screw to desired Height–of–Cut. This
setting is from the bar face to the underside of the screw
head (Fig. 13).
2. Set the Front Bracket Height "B" using the approxi-
mate dimension given by Table 1. This measurement is
between bottom surface of middle casting and top sur-
face of rod casting (Fig. 14).
