has been broken previously. It is not recommended for
use as a Plow. Use the Gravely Rotary Plow to prepare
a seedbed in one operation and the Rotary Cultivator
for cultivation throughout the season.
STORAGE
When the Cultivator is detached from the Drive
Assembly, place the small Spacers over the Studs and
secure in place with locknuts.

Usually it is necessary to detach the bars from the Depth
Wheels to make these different set-ups.
Usually the Depth Wheels provide all the adjustments
required. However, if required, the Shanks can be
moved up or down in the Shank Holders for additional
adjustment.
Five Steel Set-Up is the standard arrangement; 1 1/4
inch (3.18cm) wide steels are used. (Figure 28).
Steels are available in 1 1/4 (3.18cm) 1 3/4 (4.45cm) and
2 1/4 (5.72cm) inch widths; standard length of the

The Cultivator Toolholder, shown in Figure 28, can be
used to hold a variety of cultivating tools. The most
common set-up of cultivating tools in the Toolholder is
shown.
In addition, the Cultivator Toolholder is used to hold the
36-inch Scraper Blade.
LUBRICATION
No lubrication is required, except oiling occasionally bolt
threads for easier operation.
ATTACHING
Attaching to Tractor
:
the Toolholder is attached to the
front of the tractor the same as power attachments.
The Attachment Clutch Control should be at the OUT
position.
Attaching Tools to Toolholder
:
the individual cultivating
tool (1 in Figure 28), is attached to a Shank, (2 in
Figure 28), which in turn is attached to the Toolholder
by a Shank Holder (3 in Figure 28).
The Toolholder is equipped with five Shank Holders.
These may be moved to different positions on the
Toolholder, if desired, although this is seldom
necessary. Additional Shank Holders may be
purchased from your Gravely dealer.
To attach a tool to its Shank, simply bolt it in place with
the Bolts and Nuts provided.
To attach the Shank to the Shank Holder, loosen the
Hexagon-Head Cap Screw in the side of the Shank
Holder, slip the Shank into the Shank Holder from the
bottom, and lock the Shank in place at the desired
position by tightening the Cap Screw.
Changing Tools:
after the Shanks have been attached to
the Tool holder, changing cultivating tools requires only
the unbolting of the old tool from its Shank and bolting
the new tool on.
Parallel Bars
:
The Parallel Bars, (4 in Figure 28), can be
adjusted in several ways, depending on the task.

Six-inch (15.24cm) Hiller Set-Up uses right and left
Hillers; these can be used for closing rows as well as
for the killing. Hillers can be used to throw dirt away
from or around the plants as desired. A furrower,
available in 10 (25.40cm) or 12-inch (30.48cm) depths,
can be used with the Hillers to bring from the center of
the row to the Hillers, which in turn throw dirt around
the plants. (Figure 29)
