Adjusting The Bedknife To The Reel - Toro 04038 Operator's Manual

1. Driven pulley
2. 4 holes
8. Loosen the 4 roller bearing screws and the screw
securing the idler pulley.
9. Raise or lower the right side of the roller assembly until
the gap is less than 0.25 mm (0.010 inch).
10. Tighten the roller bearing screws.
11. Adjust the belt tension and tighten the idler pulley
mounting screw (Figure
Adjusting the Bedknife to the
Reel
Note: Use this procedure after grinding, backlapping, or
disassembly. It is not intended as a daily adjustment.
1. Position the machine on a flat, level work surface.
2. Tilt the mower back on the handle to expose the
bedknife and the reel.
Important: Do not tilt the machine back further
than 60 degrees to prevent fuel leakage.
3. Rotate the reel so that a blade crosses the bedknife edge
between the first and second bedknife screw heads on
the right side of the cutting unit
1. Bedbar adjusting screw
4. Rotate the reel so that a blade crosses the bedknife edge
between the first and second bedknife screw heads on
the right side of the cutting unit.

5. Insert the 0.05 mm (0.002 inch) shim between the
marked blade and the bedknife edge at the point where
the marked blade crosses the bedknife edge.
6. Turn the right bedbar adjusting screw until you feel
light pressure (i.e. drag) on the shim by sliding it
side-to-side (Figure
7. For the left side of the cutting unit, slowly rotate the
reel so that the closest blade crosses the bedknife edge
between the first and second screw heads.
8. Repeat steps 4 through 6 for the left side of the cutting
unit and left bedbar adjusting screw.
9. Repeat steps 5 and 6 until light drag is achieved on
both the right and left sides of the cutting unit utilizing
the same contact points.
10. To obtain light contact between the reel and bedknife,
turn each bedbar adjusting screw clockwise 3 clicks.
Note: Each click turned on the bedbar adjusting
screw moves the bedknife 0.018 mm (0.0007 inches).
Clockwise rotation moves the bedknife edge closer
to the reel and counterclockwise rotation move the
bedknife edge away from the reel.
11. Test the cutting performance by inserting a long strip
of cutting performance paper between the reel and
bedknife, perpendicular to the bedknife
Slowly rotate the reel forward; it should cut paper.
Note: If excessive contact/reel drag is evident it will
be necessary to backlap, face the front of the bedknife,
or grind the cutting unit to achieve the sharp edges
needed for precision cutting.
