Maintenance
Important To prevent damage to the hydraulic hoses,
remove the reel motors before removing the cutting units.
Lubrication
There are six grease fittings on each cutting unit (Fig. 8
and 9) that should be lubricated immediately after washing
to purge water out of the bearings and increase bearing life.
Lubricate them using a No. 2 multipurpose lithium-based
grease. For best results, use a hand-operated grease gun.
1. Wipe each grease fitting with a clean rag.
2. Grease the reel bearings (Fig. 8) until grease comes out
of the weep hole.

3. Apply grease to the front and rear roller bearings (Fig. 8
and 9) until it begins to show around the seal lips.
Important Do not apply too much pressure or the
grease seals will be permanently damaged.

4. Wipe any excess grease.
Reel Lapping
Connect a lapping machine to the cutting unit with an
extension coupler and a 9/16 in. socket. The 9/16
in.
socket can be positioned onto the capscrew on the reel shaft
inside the counterbalance weight on the end of the cutting
unit. Backlap according to the procedures in the Toro
Sharpening Reel and Rotary Mowers Manual, Form No.
80-300PT.
Note: For a better cutting edge, run a file across the front
face of the bedknife when the lapping operation is
completed. This will remove any burrs or rough edges that
may have built up on the cutting edge.
Contact with moving parts may cause personal
injury.
Keep your body away from the reels during reel
lapping.
Caution
Removing the Bedknife for
Grinding
Important To prevent damage to the hydraulic hoses,
remove the reel motors before removing the cutting units.
The rear roller assembly must be removed before removing
the bedknife assembly for sharpening. To remove the rear
roller, proceed as follows:
1. Remove the capscrew and nut anchoring the rear roller
height-of-cut bracket to the side plate on both ends of
the cutting unit (Fig. 10).
