Setting Cutting Unit Attitude - Toro Reelmaster 5200-D Service Manual

Setting Cutting Unit Attitude

Cutting unit "attitude" has a significant impact on the per-
formance of the cutting unit. Attitude refers to the angle
of the bedknife relative to the ground (Fig.11).
Adjustable front and rear brackets allow for variable ad-
justment of cutting unit attitude within the height-of-cut
range. All cutting units on a given machine must be set
to the same attitude, otherwise after-cut appearance
could 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
(Bermuda, Zoysia) while cool season grasses (Blue-
grass, Rye) may require more aggressive attitudes (ex-
ample: 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 bedbar or other parts
of the cutting unit to drag in the turf causing tufting.
Therefore, minimum recommended attitude is 1 degree.
For setting consistent cutting unit attitude, Toro strongly
recommends using a two-screw gauge bar, Toro part no.
98-1852 (Fig.12). The Height of Cut Screw is set for
height-of-cut, and the Attitude Screw is set for cutting
unit attitude. The Attitude Screw is only used when the
Adjustable Front Height of Cut Kit (Part No. 104-8205)
is installed on the cutting unit.
Note: The Attitude screw setting is an easy method of
transferring cutting unit attitude to all cutting units on a
machine.
Note: The Attitude 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.
Table 1 lists starting dimensions for setting up a new cut-
ting unit with attitudes of 2, 4, 6 and 8 degrees.
