Finishing Blade Attachment
For an exceptionally smooth disking job on outside rear (such as in flood irrigation operations), a finishing blade is available. This blade is in addition to integral furrow filler and further feathers soil from outside front blade.
An 457 mm (18 in.) three lobe blade (B) is recommended. This gives outside rear gang a 508, 457, and 457 mm (20, 18 and 18 in.) taper to minimize small valley left by outside blade. Even though 3-lobe blade is an 457 mm (18 in.) blade like integral furrow filler next to it, cutouts in blade feather soil better than a 406 mm (16 in.) solid blade.
A finishing blade scraper (A) is provided to prevent soil build-up on finishing blade.
