5. Remove the V–ring from the sleeve on each end of
the reel shaft (Figure 7).
Note: Inspect the sleeves and replace them as
required. A special sleeve driver is available; contact
your Toro Distributor to obtain this tool. Press a new
sleeve onto the end of each reel shaft until the sleeve is
flush with the step in the shaft.

6. Install a new V–ring, flat side first, onto each end of the
reel shaft until it is completely inserted onto the sleeve.
7. Apply anti–seize lubricant to the bearing journals of
the cutting reel (Figure 2 and Figure 3). Position the
reel with the pitch arms and the bushings in the frame
to accept the bearing housings.
Note: The reel shaft end with the keyway should be
on the left side of the frame.
CAUTION
Contact with the reel, bedknife, or any other
cutting unit parts may result in personal
injury. Use heavy gloves when handling the
cutting unit.

Finishing the Installation
No Parts Required
For Models with Integrated Bearing
Housings
1. Insert both side plates onto the reel shaft. If necessary,
tap it into position with a soft hammer.
2. Attach the side plates to the frame.
3. Secure the rear roller.
Figure 7
2. V-ring
For Models with Removable Bearing
Housings
1. Insert both the bearing housings (Figure 3) through the
frame onto the reel shaft.
2. Push the housing onto the reel shaft. If necessary, tap
it into position with a soft hammer.
3. Attach the bearing housing to the side plate of the
cutting unit with the 2 plow bolts and tapered nuts.
Tighten the fasteners.
For All Models
1. Apply anti–seize lubricant to the internal threads of the
bearing lock nut (Figure 2 and Figure 3). Block the reel
with a piece of wood to prevent it from turning. Install
and tighten the bearing lock nut to the reel shaft.
Note: The reel bearing lock nut has left hand threads.
2. Install the counterweight to the right side of the cutting
unit with the previously removed hardware (Figure 2
and Figure 3).
3. Install the spacer in the left side reel bearing housing
(Figure 1). Mount the reel drive plate assembly to
the side of cutting unit with the previously removed
locknuts, capscrews, and lockwashers. Tighten the
fasteners to secure the assembly.
4. Install the spacer and woodruff key to the reel shaft
(Figure 2 and Figure 3). Apply anti–seize lubricant to
the internal bore of the drive pulley and position the
pulley onto the reel shaft. Install and tighten the flange
nut that secures the pulley to the reel shaft.
5. Check for free movement of the reel assembly by
rotating the pulley. If binding is noted, identify and
correct the problem.
Note: The Flex 21 will have slightly greater reel drag
than other Toro greens mowers due to the reel seal
design.
6. Install the reel drive belt to the pulley and drive
assembly (Figure 1). Adjust the drive belt tension and
install the belt cover; refer to your Operator's Manual for
the adjustment procedure.
7. Install the front roller.
8. Install the bedbar to the cutting unit.
9. Install the cutting unit to the traction unit.
