OPERATION AND MAINTENANCE
4-5
General Operation
1.
The horsepower requirements are typically 8-10
horsepower per foot of cut. This will vary widely due
to speed, depth, moisture, residue and types of soils.
Local dealers can help in making recommendations
for your areas.
2.
Set the unit working depth (1 - 5 inches) by adjusting
the stroke control on the master cylinder. For stability,
it is important that the lift wheels always apply slight
pressure against the soil.
3.
Operating speed is typically 5-8 mph. Excessive
speed can cause the unit to bounce, uneven depth,
and create a ridge on the outside edges.
4.
Lift wheels must always be in contact with the ground
and carrying some implement weight. Lift wheels are
used to gauge the depth of each frame section and to
control the leveling feature. Maximum discing depth
cannot be achieved by raising the lift wheels off the
ground. Little or no weight on the lift wheels will
cause the frame sections to gouge, side-draft, and
buckle producing inconsistent cutting depth.
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
“General Torque Specifications”
and
when re-tightening
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.
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)
. Install the transport
locks in the storage position
..
2.
Unfold the wings and extend the fold cylinders
completely.
3.
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
“Leveling (Front-to-Rear)” on page 4-6
.
Adjusting Working Depth
The operating depth of the Tilloll is controlled by adding
or removing stroke control stops to the 2 master lift
cylinders
. These stroke control stops are
located on the outside of the main frames near each
master cylinder.
1.
Adjust the working depth by adding or removing
stroke control stops. Adding stops will decrease the
operating depth while removing stops will increase
the operating depth.
2.
Use the same number and size of stroke control
stops for each master cylinder. This will ensure that
the 2 master cylinders remain in time with each other.
Failure to do so will cause damage to the implement.

3.
After adjusting working depth, check the front to rear
levelness while at that working depth. This will need
checked after any adjustments to the working depth
