Refer to Figures 2-2, 2-3, 2-4 & 2-5:
1.
Determine correct orientation of scraper mounting
brackets (#1) by locate the figure that illustrates your
Disc Harrow model number and disc blade spacing.
Be sure to check the disc blade spacing on both the
front and rear disc gangs as they can be different.
Mounting brackets for disc gangs with 7 1/2" blade
spacing will have more square holes than ones with
9" blade spacings.
