(Old) Disc Scraper Adjustment:

Prior to first use, and periodically thereafter, inspect all

disc scrapers for proper gap and adjust as needed.

Reverse scraper blades when the specific adjustment

is no longer possible. Replace the scrapers when

either side can no longer be adjusted to the proper

gap.

1) Adjust the scraper blades by loosening the two car-

riage bolts (8). Slide and rotate the scrapers and re-

tighten the bolts when finished.

gap is not set, the blade will plug.

(New) Disc Scraper Adjustment:

Prior to first use, and periodically thereafter, inspect all

disc scrapers for proper gap and adjust as needed.

Replace the scrapers when they can no longer be

properly adjusted.

1) Adjust the scraper blades by loosening the two bolts

(9). Rotate the scraper until 1/16" to 1/8" gap between

the scraper and blade is achieved and re-tighten the

bolts when finished.

Note: This measurement is essen-

tial for proper trash flow.

Cast Roller Adjustment (Optional):

The roller attachment is designed to size clods and

consolidate the soil profile. It can be hydraulically

adjusted with a reference gauge on the left wing.

1) Set the blue hydraulic circuit to Float and take note

of the roller reference gauge reading.

2) While making a tillage pass, set the blue hydraulic

circuit to neutral to lock the roller in position.

3) Moving the gauge toward "E" reduces down pres-

sure while moving the gauge toward "A" increases

pressure.

Note: The roller is capable of lifting the rear gang out of

the soil and disturbing the fore/aft setting. When

increasing roller pressure, ensure that the machine

does not raise as the pressure increases.

4) If wheel tracks or power hopping occurs, increase

the roller pressure.

5) Note the reference gauge setting for future use.
