Adjustable Hold Downs for Standard Guards
The adjustable hold down clips, 1, are spaced across
the cutter bar. There is not a clip at every guard as the
top lip on the guard helps to hold the knife from lifting too
far.
The lip at the rear edge of the clip holds the rear of the
knife section in place. At the center and all clips to the
right of center, a 3 mm (0.120
″
) shim, 2, is installed
under the clip. All clips should have a clearance of 0.13
mm (0.005
″
) to 0.6 mm (0.025
″
) between with the knife
section and clip at “X”. In some cases a 0.25 mm
(0.010
″
) shim, 3, is required to obtain the proper
clearance. If the clearance is less than 0.13 mm
(0.005
″
), the knife may not move freely.
The front of the clip should be adjusted by tightening
flanged nut, 4, to obtain a clearance of less than 0.020
″
between the clip and knife section at “Y”. To
compensate for the initial “break-in” wear, check the
clearance and adjust, if required, after the first 50 acres
of operation.
If replacing a clip, be sure to place the 3/8
″
x 1-1/4
″
plow
bolt, 5, for the adjustable clip through the clip before
installing the clip.
NOTE: Be sure a 3 mm (0.120”) shim, 6, is installed
between the center guard and cutter bar and also
between all the guards to the left of center and the cutter
bar.
IMPORTANT: Check and adjust the guard alignment
before checking the hold down clip adjustment.

One Piece Hold Down Clips for Standard
Guards
The one piece hold-down clips, 1, are spaced across the
cutter bar. There is not a clip at every guard as the top
lip on the guard helps to hold the knife from lifting too far.

″
) shim is installed
between the center guard and cutter bar and also
between all the guards to the left of center and the
cutter bar.
The lip, 2, at the rear edge of the clip holds the rear of
the section in place. At the center and all clips to the
right of center, a 3 mm (0.120
″
) shim is installed
between the clip and cutter bar at 3. All clips should
have a clearance of 0.13 mm (0.005
″
) to 0.6 mm
(0.025
″
) between with the knife section and lip. In
some cases a 0.25 mm (0.010
″

obtain the proper clearance. If the clearance is less
than 0.13 mm (0.005
