Note: If reel makes contact on both sides of
bedknife but still does not cut paper,
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.
80–300PT).

A. Loosen the pivot hub lock nuts to allow movement
of the pivot hub casting (Fig. 5).
5. If paper was not cut on the left side: loosen the bottom
adjusting nut on the pivot hub, then turn the top
adjusting nut clockwise to pull the pivot hub up. OR If
paper was not cut on the right side: loosen the top
adjusting nut on the pivot hub, then turn the bottom
adjusting nut counterclockwise to push the pivot hub
down (Fig. 5).
Note: To reduce thread play, always tighten the
bottom adjusting nut last.
6. Recheck reel to bedknife contact on both ends of the
bedknife, and repeat step 5 as necessary.
Note: Reel to bedknife contact may become too
tight or too loose after previous
adjustment; therefore, turn bedknife
adjustment knob, accordingly, for light
contact.
7. Retighten pivot hub lock nuts.
Note: Recheck if paper cuts on both ends, to
insure the bedknife did not move when
re–tightening the pivot hub lock nuts.
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. 6). 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.
ATTITUDE
Figure 6
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. Cutting unit attitude can be adjusted
throughout the cutting season to allow for various turf
conditions.
In general, less aggressive attitudes (example: 2
degrees) are more appropriate for warm season
grasses (Bermuda, Zoysia) while cool season grasses
(Bent, Bluegrass, Rye) may require more aggressive
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 bedbar or other parts of the cutting unit to drag in
the turf causing tufting. Therefore, minimum
recommended attitude is 1 degree.
