Landoll 875-18, Operator'S Manual

Page: 55 / 64

CAUTION
DRIVE AT REASONABLE SPEEDS TO
INSURE YOUR SAFETY. SLOW DOWN
BEFORE MAKING SHARP TURNS OR
USING THE BRAKES. DRIVE SLOWLY
OVER ROUGH GROUND, SIDE HILLS,
AND AROUND CURVES TO AVOID TIP-
PING.
4-5.2 Check the front to rear leveling of the
frame. Adjust radius rod until frame is level
at working depth and all sections of the ma-
chine are cutting at the same depth (See
Figure 4-4).
4-5.3 Set the unit working depth (1 - 5 inches)
by adjusting the stroke control on the master
cylinder. For stability, it is important that the
gauge wheels always apply slight pressure
against the soil.
4-5.4 Select proper speed (from 5 - 8 miles
per hour) for best results.
4-5.5 Always lift the Tilloll completely out of
the ground before turning or backing. This
prevents shank, disc, or harrow damage or
damage to their respective mounting brack-
ets.
4-5.6 It is important to keep all bolts tight at
all times, especially during the first few hours
of operation. Be sure to check the shank U-
bolts and pivot bolts. Tighten wheel lug bolts
to 90 ft-lbs of torque. After break-in period,
check them periodically. Loose bolts can re-
sult in lost, broken, or prematurely worn
parts and unnecessary down time. Refer to
torque specifications in Tables 2-1 and 2-2
when retightening loose bolts.
4-5.7 Reduce speed at field ends, and lift the
Tilloll completely out of the ground before
turning.
4-5.8 When operating in the field, run the im-
plement with a minimum overlap of one foot
to insure an even mixing and leveling of the
soil.
4-6 DISC GANG SCRAPER ADJUSTMENT
4-6.1 To adjust the pressure of the disc gang
scrapers, loosen the U-bolts that hold the
scraper assembly in place. Slide the scraper
assembly toward the disc blades until there
is enough pressure on the scrapers to clean
the discs.
IMPORTANT
THE SCRAPER BLADES ARE REVERSIBLE TO
ALLOW EXTENDED USE BEFORE REPLACE-
MENT IS REQUIRED.
IMPORTANT
THE STRAIGHT COULTER AT THE END OF
EACH DISC GANG IS TO CONTROL THE FLOW
OF SOIL OUT OF THE SIDE OF THE MACHINE.
