4. When it becomes necessary to adjust the reel to the
bedknife, instruct the operator to disengage the reel,
stop the engine and remove the key from the ignition
switch. Then proceed with the adjustment only after
the reels have stopped rotating.
5. Backlap each reel until the cutting edges are sharp,
even, and consistent on all blades. Achieve a minimum
of 1/32 in. (0.79 mm) land area on newly sharpened
reel assemblies. Normally, a reel need only be
backlapped for approximately 3 minutes.
6. Upon completion, stop the reel and turn off the engine.
Remove the key from the ignition switch. Wash the
unit thoroughly with a low pressure stream of water to
remove all lapping material. Allow the reel to dry and
lubricate the grease fittings.
7. Check sharpness of the reel and bedknife with strips of
newspaper. With light reel to bedknife contact, the
paper should be cleanly sheared across the entire width
of the reel. If the paper is not sheared acceptably,
continue backlapping.
8. After backlapping the #1, #2 and #3 cutting units, raise
and latch these units and proceed with the #4 and #5
cutting units.
Note: See the Toro Sharpening Manual (Part No. 80-300)
for additional backlapping/sharpening information.
Servicing the Bedknife/Bedbar
Note: The bedbar on each cutting unit has a precision
ground mounting surface to provide an excellent fit with a
bedknife. Backlapping of replacement bedknives is often
sufficient to achieve an excellent cutting edge with
minimum material removed.
Removing the Bedknife/Bedbar
1. Remove the shoulder bolts, bushings, and spacers from
each end of the unit and remove the bedbar/bedknife
assembly (Fig. 25).
