ATTACHING ROLLING HARROW II TO PRIMARY
TILLAGE TOOL
Before attaching the ROLLING HARROW II to
your primary tillage tool, adjust the extended
length of the hitch tube to give adequate turn-
ing clearance (between the two implements)
when turning on the ends.
NOTE: It may be necessary to reposition the
rear hose holder when adjusting the hitch tube
length.
Adjust the hitch tube length (as required) by
removing the two klik-pins (9951) and 1" dia.
pins (91363) in the front of the hitch frame.
Position as required and reinstall pins as before.
Back primary tillage tool into position, make
necessary adjustments (to align tongue and
implement hitch) and attach to the rear of
implement. Use a 1" dia. hitch pin and lock
in place.
NOTE: If unit is parked in the raised position,
turn handle on jackstand to remove pressure
and rotate jackstand into "Transport Position",
see "Jackstand" page 38).

PREPARING ROLLING HARROW II
OM01408
Wear clips (Fig. 1-1) are provided on the ends
of each rolling harrow frame (two on the front
aggressive basket and one on the rear). They
are especially important when your ROLLING
HARROW II is used in wet sandy soils which
tends to build-up on end wheels of the bas-
kets. This highly abrasive soil can cause the
basket frame end plates to wear through or
damage zerk.
If operating under these conditions, be sure
the wear clips are in place, and the mounting
hardware is tight.
