Bedknife Replacement

2. Remove bedknife screws and remove bedknife.
3. Remove all rust, scale, and corrosion from bedbar
surface before installing the bedknife.
4. Install new bedknife with new bedknife screws
(57-4910). Apply clean SAE 30 oil to the screws before
installing screws. Tighten the screws to a torque of 200
to 250 in-lb. working from the center toward each end of
the bedbar (Fig. 25).
5. Grind the new bedknife to match it to the bedbar.
Note: For proper grinding of bedknife, follow proce-
dures in the Toro publication "Sharpening Reel and
Rotary Mowers", Form No. 80-300-PT.

Preparing Reel for Grinding
IMPORTANT: Adjust reel bearings before grinding
reel. (See Reel Bearing Service and Adjustment in
the Adjustments section of this chapter).
1. Remove bedbar.
Note: Some reel grinders may require rear roller as-
sembly be mounted to the cutting unit for proper support
in reel grinder. Rear roller must be parallel to reel shaft
to remove taper when grinding.
2. If necessary, remove front roller assembly.
A. Loosen the locknuts securing height of cut ad-
justing rods at both ends of the cutting unit and the
roller shaft clamp bolts (Fig. 26).
B. Turn height of cut adjustment knobs until they
are disconnected from the height of cut adjusting
rods (Fig. 26). The roller assembly can then be re-
moved from the cutting unit by pulling evenly on
both sides.
For proper grinding of reel, follow procedures in the Toro
publication "Sharpening Reel and Rotary Mowers",
Form No. 80-300-PT.
3. Install bedbar. After grinding, assemble cutting unit,
and do all adjustments. Backlap if necessary to get de-
sired fit between reel and bedknife.
