Note: Determine the left and right sides of the
machine from the normal operating position.

Adjustments

Adjusting the Bedknife to the Reel
Bedknife to reel adjustment is accomplished by
loosening or tightening bedbar adjusting screws, located
on top of mower.
1. Position machine on a flat, level work surface. Make
sure reel contact is removed by turning bedbar
adjusting screws counterclockwise (Figure 8).

2. Tilt mower on back, onto the cutting unit kickstand,
to expose bedknife and reel.
Important: Make sure nuts on back end of
bedbar adjusting screws are not resting on the
work surface (Figure 8).
3. At one end of reel, insert a strip of newspaper
between reel and bedknife (Figure 9). While slowly
rotating reel forward, turn bedbar adjusting screw
(Figure 8) clockwise (on same end of reel, one
click at a time, until paper is pinched lightly, when
inserted from the front, parallel to the bedknife. A
slight drag will be noted as the paper is pulled.
Note: Each time adjusting screw is rotated one
click clockwise, bedknife moves .0009 in (.023 mm).
closer to reel. Do not overtighten the adjusting
screws.
4. Check for light contact at other end of reel using
paper and adjust as required.
5. After adjustment is accomplished, check to see if
reel can pinch paper when inserted from the front
and cut paper when inserted at a right angle to the
bedknife (Figure 9). It should be possible to cut
paper with minimum contact between the bedknife
and the reel blades. If excessive contact/reel drag
is evident it will be either necessary to back lap or
regrind the cutting unit to achieve the sharp edges
needed for precision cutting (Refer to the Toro
manual for Sharpening Reel and Rotary Mowers,
Form No. 80-300PT).
Adjusting the Rear Roller
1. Adjust the rear roller brackets (Figure 10) to the
desired height of cut range by positioning the
required amount of spacers below the side plate
mounting flange (Figure 10) per the HOC Chart.

2. Raise rear of cutting unit and place a block under
bedknife.
3. Remove (2) nuts securing each roller bracket and
spacer to each side plate mounting flange.
4. Lower roller and screws from side plate mounting
flanges and spacers.
5. Place spacers onto screws on roller brackets.
