Field Operation; Disc Gang Scraper Adjustment - Landoll Tilloll 875 Series Operator's Manual

Field Operation

1. Raise the unit to take the weight off of the transport
locks. Remove the transport locks from the lift
cylinders (on the main frame only) (See Figure 4-4.)
IMPORTANT
When folding or unfolding wings, operate tractor
engine at a slow idle on 15'F units and a fast idle on
18', 21', 25'-6" units, and hold hydraulic valve on
tractor open to assure smooth operation.

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 tipping.
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 machine are cutting at the same
depth (See Figure 4-4.)

OPERATION AND MAINTENANCE
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. Select proper speed (from 5 - 8 miles per hour) for
best results.
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 brackets.
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 result in lost, broken, or prematurely worn parts
and unnecessary down time. Refer to torque
specifications in Table 2-1 and Table 2-2 when
retightening loose bolts.
7. Reduce speed at field ends, and lift the Tilloll
completely out of the ground before turning.
8. When operating in the field, run the implement with a
minimum overlap of one foot to insure an even
mixing and leveling of the soil.

Disc Gang Scraper Adjustment

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 replacement 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.
