OPERATING INSTRUCTIONS
WHEN TO SHARPEN THE BEDKNIFE
When the grass is not being cut cleanly, or the cut
ends of the grass appear torn or ragged, the edges
of the reel blade and bedknife have become rounded
and need sharpening. See FIG. 1A. The purpose of
sharpening is to restore the sharp edges to the reel
and bedknife.
IMPORTANT: To fully sharpen a reel mower, you
need to grind the reel blades (using a Reel Grinder)
and reshape the cutting edge of the bedknife.
NOTE: New bedknives should be ground before
being put into use. New bedknives deform and move
to match the shape of the bedbar at the time of
installation and therefore MUST be ground to a
straight surface after installation.
BEDKNIFE GRINDING ANGLES
The bedknife has two faces that normally need to be
ground, the top face and the front face (on some
models, the front face may be curved and may not
need grinding).
The proper grinding angles for the two faces will vary
depending on the model. Always follow the
manufacturer's recommended specifications
for bedknife angles.
Typical Bedknife angles:
There will be a +4 to -10 degrees clearance
angle ground on the top face. The angle is
usually measured relative to the bedknife
mounting surface. See FIG. 2A.
+4 TO - 10
FIG. 1

There will be a 0-30 degrees clearance angle
ground on the front face. The angle is
usually measured relative to a line

5. After you install a new or different wheel, it is recommended that you dress it before grinding. (See
next page) Dressing the wheel trues the grinding surface of the wheel and removes the hard glaze
sometime remaining from the manufacturing process. Dressing the wheel properly prepares the wheel
for grinding.
REPLACING THE WHEEL
A new vitrified grinding wheel is 2" [51 mm] deep. Replace the
wheel when it wears down to a depth of 0.75" [19 mm].
See FIG. 6.

OPERATING INSTRUCTIONS (Continued)
BEDKNIFE ALIGNMENT (TOUCH METHOD)
After securing the bedknife on the tooling support
assembly, the bedknife face must be aligned to the
grinding head. Using the gauge as described on the
previous pages will get the alignment very close. For
maximum bedknife life use the following touch method
to finish the alignment of the bedknife to the grinding
head.
Alignment is accomplished by touching the
grinding wheel to the bedknife.
With the bedknife set to the correct angle, move the
grinding head to the right end of the bedknife. Now,
rotate the infeed handwheel until the wheel just
touches the bedknife at the end nib of the knife face
on a used bedknife, or the full knife face on a new
bedknife. On used bedknive if you wish to grind to
match the worn bedknife, then touch the grinding
wheel inside the end nib See FIG. 18.
Next, move the grinding head to the left end of the
bedknife. Now without moving the grinding head
infeed, adjust the tooling bar left side adjuster until
the grinding wheel just touches the bedknife end nib
or the knife face on a used bedknife, or the full knife
face on a new bedknife. Again, on a used bedknife if
you wish to grind to match the worn bedknife, touch
the grinding wheel inside the end nib. See FIG.19.
Because when you adjust the left side, the right side
also moves a small amount, you should go to the
right and left sides several times to verify that you
just contact the knife at both ends. This can be
done while grinding the knife.

OPERATING INSTRUCTIONS (Continued)
Top Face Grinding
REFER TO THE "SAFETY RULES WHEN GRINDING" ON PAGE 4 AND 5.
1. Mount the bedknife between the centers.
2. Rotate the bedknife and bedknife support forward until the angle finder reads the correct angle for grinding the
top face. Firmly tighten all knobs to assure the angle of the support and bedknife does not change during
grinding.
3. The front of the wheel must extend into the gutter of the bedknife. If it does not extend into the gutter, the
ground surface may not be flat after grinding. If necessary, rotate the grinding head to assure that the edge of
the wheel extends into the gutter of the bedknife. Infeed the grinding wheel until it is a few thousandths of an
inch away from the bedknife surface.
4. If the wheel does not clear the entire length of the bedknife, or if the bedknife is not aligned with the grinding
wheel, it may be necessary to align the bedknife using the gauge and the adjustments for up & down and in &
out.
5. When you have completed the set up, check to assure that all knobs and stops are secure, then with the
grinder turned off, travel the carriage from end to end to assure that the grinding wheel will grind only the
bedknife and clears all other parts of the machine and the bedknife.
6. Turn on the grinding motor switch and slowly infeed the wheel to the bedknife until there is a light grind. Turn
the infeed handwheel counterclockwise to infeed the grinding wheel. Manually traverse the carriage back and
forth. When infeeding, only infeed a maximum of approximatly .002-.003” [.05-.075mm] .
IMPORTANT! NEVER ALLOW THE BEDKNIFE EDGE TO CHANGE COLOR OR YOU MAY LOSE THE
TEMPER IN THE BEDNIFE EDGE.
IMPORTANT! When manually traveling the carriage on the BG1000, it is very important to use consistent
speed and pressure. Do not lean on the machine or bump the rails.
NOTE: During the grinding process, watch the spark pattern for the full length of grind, the sparks
should look equal for the full length of grind.
NOTE: If an excessive amount of metal stock will have to be removed on one end of the
bedknife, recheck your setup first and then the straightness of the bedknife. If it is bowed or
twisted, replace it.
7. Continue grinding the bedknife in this manner until you are satisfied with the top face grind. Dress the wheel
when necessary.
8. Dress the wheel before the final spark out grind. On the spark out passes, infeed the grinding wheel only about
.001" [.025 mm] and then let the grinding wheel spark out. For sparking out, always traverse the grinding head
10 to 20 passes without infeeding the grinding head. To get the finest top-face grind, traverse at a slow speed
for this final grinding sparkout. This process improves the surface finish of the grind and improves the grind
quality.
NOTE: What you are looking for is a "near sparkout" - about a 99% reduction in grinding spark
from a normal grind. Don't continue sparking out until you have no sparks, because this could
be an extremely long time.
By partially grinding both surfaces, the top face and the front face, you will resharpen a used bedknife with the least
metal removal. Partially grinding both surfaces is the preferred method for life utilization of the bedknife. See Fig 20
FIG. 20
20
OPERATING INSTRUCTIONS (Continued)
Front Face Grinding
NOTE: Some bedknives require front face grinding. Check with the bedknife manufacturer to determine if front
face grinding is required.
1. Rotate the bedknife and bedknife support back to the desired angle.
2. Infeed the grinding wheel until it is a few thousandths of an inch away from the bedknife front surface.
3. If the grinding wheel does not clear the entire length of the bedknife, or if the bedknife is not aligned with the
grinding wheel it may be necessary to align the bedknife.
4. Turn on the grinding motor switch and slowly infeed the wheel to the bedknife until there is a light grind. Turn
the infeed handwheel counterclockwise to infeed the grinding wheel. Manually traverse the carriage back and
forth. When infeeding, only infeed a maximum of approximatly .002-.003” [.05-.075mm] .
IMPORTANT! NEVER ALLOW THE BEDKNIFE EDGE TO CHANGE COLOR OR YOU MAY LOSE THE
TEMPER IN THE BEDNIFE EDGE.
IMPORTANT! When manually traveling the carriage on the BG1000, it is very important to use consistent
speed and pressure. Do not lean on the machine or bump the rails.
NOTE: During the grinding process, watch the spark pattern for the full length of grind, the sparks
should look equal for the full length of grind.
NOTE: If an excessive amount of metal stock will have to be removed on one end of the
bedknife, recheck your setup first and then the straightness of the bedknife. If it is bowed or
twisted, replace it.
.
5. Continue grinding the bedknife in this manner until you are satisfied with the front face grind. Dress the wheel
when necessary.
6. Dress the wheel before the final spark out grind.
WHEN REMOVING THE BEDKNIFE FROM THE MACHINE
TAKE CARE AS THE CUTTING EDGE OF THE BEDKIFE IS
EXTREMELY SHARP.
