Setting Cutting Unit Attitude - Toro 03527 Operator's Manual

B. Setting Cutting Unit Attitude
Important
Cutting unit "attitude" has a significant
impact on the performance of the cutting unit. Attitude
refers to the angle of the bedknife relative to the ground
(Fig. 7). 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, otherwise after-cut
appearance could be negatively affected.

Note: Due to wear on the bedknife and reel, over time the attitude of the cutting unit will decrease.

The front brackets have 3 fixed positions for setting
cutting unit attitude within the same height–of–cut range
(Fig 7). Each change in position changes the cutting unit
attitude by 3 degrees. The positions are:
Position A: Very Aggressive
Position B: Aggressive (Normal)
Position C: Less Aggressive
Adjustable Front Height Of Cut Kit, Toro Part No.
104–8205, allows for variable adjustment of cutting unit
attitude within the height–of–cut range.
The best cutting unit attitude is dependent on your turf
conditions and desired results. Experience with the
cutting unit on your turf will determine the best setting to
use.
In general, less aggressive attitudes (position C) are more
appropriate for warm season grasses (Bermuda, Zoysia)
while cool season grasses (Bluegrass, Rye, Bent) may
require more aggressive attitudes (position B or A). 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.
