Replacing the Blades
Removing the Blades from the Shaft
1. Secure the end of the verticutter shaft that has only 1
washer and 1 nut in a vise.
2. On other end of the shaft, rotate the nut
counterclockwise and remove the nut.
WARNING
The blades are extremely sharp and may have
burrs that will cut your hands.
Use caution when removing the blades from
the shaft.
3. Remove the small spacer, the washer, the blades, and
the large spacers.
Important: Do not invert the verticutter reel blades
when disassembling or reverse the order when
assembling them. Note the verticutter blades index
hole. The index hole is provided for assembly in order to
obtain the proper helix for the verticutter reel.
Installing the Blades
1. Clean and lubricate the square shaft with a light coating
of grease.
2. Install a blade.
3. Install a spacer.
Important: Do not invert the blades when
installing them on the shaft. If the blades are
inverted, the blades that are in use (rounded) will
be mixed with the sharp ends of the blades that
were not in use. This will cause unsatisfactory
performance in the verticutter reel unit. Pay
close attention when removing and installing the
verticutter blades.
4. Install the next blade clockwise so that the index
reference hole
(Figure
blade hole by 1 flat of the shaft.
1. Index reference hole
18) is not aligned with the first
Figure 18
5. Continue to install spacers and blades in this manner
until the full complement of blades have been installed.
Note: When properly assembled, the blades are
staggered in such a manner as to appear like a helix.
6. Install the small spacer to the shaft.
7. Apply blue Loctite 242 to the nut.
8. Install the nut onto the shaft, (machined side of the nut
toward the spacer) and tighten it to 108 to 136 N∙m
(80 to 100 ft-lb).
