IMPORTANT: If unit is unhooked in the trans-
port position, install hydraulic cylinder trans-
port locks (Fig. 1-4) and lower jackstand to
ground before unhooking unit.
NOTE: Refer to "Jackstand" (page 38) for
positioning of jackstand into "Parked Posi-
tion" (Fig. 3-17).
When parking ROLLING HARROW II onto rear
jackstand, lower jack down into position and
UNHITCHING
turn handle to transfer the weight of the unit
to the jack.
Remove hitch pin.
CAUTION! SERIOUS PERSONAL INJURY
CAN RESULT IF YOU ATTEMPT TO DIS-
CONNECT HYDRAULIC HOSES UNDER PRESSURE.
SHUT OFF TRACTOR ENGINE AND WORK LEVERS
BACK AND FORTH BEFORE DISCONNECTING
HOSES.
Disconnect the hydraulic hoses. Install dust
covers over the hose plugs and outlets.
IMPORTANT: Before unhitching the primary
tillage tool, refer to the units "Operator's
Manual" for unhitching procedures.
FIELD ADJUSTMENTS
OPERATIONS
ROLLING HARROW BASKET
The Rolling Harrow basket is designed to help
provide an excellent seed-bed when used in
conjunction with your primary tillage tool.
To obtain maximum performance from your
ROLLING HARROW II in the field, it may be
run with the transport wheels in the "Raised"
or "Float" position. This allows maximum trans-
fer of weight to the baskets, thus providing for
better leveling and ground working action (by
allowing the unit to more closely follow the
ground contour).
Normally the ROLLING HARROW II should
run with the basket frame in the free-floating
position (allowing the unit to more closely
follow the ground contour and roll over rocks
and obstructions in the field), thus prolonging
the life of the baskets. To obtain a "Free-
Floating" basket frame, remove lock-out pins
from basket frame and store in mounting arms
(Fig. 1-6).
FIG. 1-6
In some conditions, it may be desirable to
limit the float of the basket frame:
LIMIT FLOAT
A. Raise ROLLING HARROW II to transport
position.
B. Remove pin from storage position and
place in desirable hole in basket frame.
NOTE: Place pin in slot for maximum lock-out.
Be sure to position pins in the same hole from
side-to-side on each basket section.
IMPORTANT: IN ROCKY CONDITIONS , the
life of the baskets may be shortened if the
unit is pinned with the front basket locked in
the down position.
NOTE: IN LIGHTER SOILS , depending on the
depth, speed, and soil condition, it may be
desirable to limit the penetration of the front
basket, by placing the lock-out pin in one of
the three holes (in basket frame) on the back-
side of the mounting arm.
NORMAL POSITION
ROLLING HARROW II RUN WITH AGGRES-
SIVE BASKET POSITIONED TO THE FRONT
(FIG. 1-6) FOR MAXIMUM PENETRATION IN
NORMAL SOIL CONDITIONS.
A maximum amount of leveling and condition-
ing of the soil is obtained when the aggres-
sive basket is positioned to the front (as shown
in Fig. 1-6). This position also helps provide
for thorough mixing of chemicals into the top
two to three inches of the soil, when used for
incorporation.
