Disc Blades
1.
The 7431 VT Plus is equipped with 22" -6 ga. (.197"),
22" -4 ga. (.256), or 22" -4 ga. (.256) rollable low
concavity disc blades on both front and rear. The use
of other concavity blades can give unpredictable
results and is not recommended.
2.
Sharpening – In some cases there is a desire to
sharpen disc blades for improved cutting. There are
several people who roll-sharpen disc blades. Most
disc blades used today are made of chrome-boron
steel. The chrome-boron steel has a higher hardness
than traditional carbon-steel blades for increased
wear. Higher hardness makes roll sharpening more
difficult often with mixed results, and is not covered
by warranty. Disc blade manufacturers will not cover
any alterations to blades other than the place of
manufacture. Results from roll-sharpening damage
may not be immediate, and may take more than a
season to be noticeable. If you choose to sharpen
disc blades, check with local dealers for reputable
experienced sharpeners that will stand behind their
work.
DANGER
Disc blades are extremely sharp. Exercise
extreme care when working on or near disc
blades. Do not allow discs to roll over or fall onto
any bodily part. Do not allow wrenches to slip
when working near disc blades. Never push
wrenches toward disc blades. Do not climb over
machine above disc blades. Failure to stay clear
of disc blade edges can cause serious personal
injury or death.
