lEVElING
When leveling your MAXIMUS DISK, position the
tractor with the implement on a level surface.
Check the tractor tire pressure and inflate equally
from side-to-side. See your tractor operator's
manual for correct tire inflation pressure.
With the MAXIMUS DISK attached to the tractor,
raise the implement a couple of inches off the
floor. Shut-off the engine and lock the brakes
on the tractor. Level the implement frame from
side-to-side by adjusting the lift links on the
tractor 3-point hitch.
For initial adjustment, with the MAXIMUS DISK
still raised off the ground a couple of inches
(being sure the bottom of the soil conditioning
baskets clear the floor), stand at the side of
the implement and sight across the top of the
implement frame and floor.
If the MAXIMUS DISK frame is not level from front
to back with the ground line, turn the center link
on the tractor either in or out until the implement
frame is parallel to the ground line.
Further front-to-back adjustment may be required
once the machine is operated in the field. When
properly leveled, all disk blades will enter the
ground to a uniform depth.
TRANSPoRTING
Comply with all state and local governing
highway safety and regulation when moving
machinery on public roads.
Be sure SMV Emblem is in place and clearly
visible on rear of the tractor.

UNhITChING
Lower the implement on a flat surface, clear of
any debris or obstruction, and unhitch the unit.
MAXIMUS DISK oPERATIoNS
Worn blades will not penetrate, cut, or level as
well as new ones. A new blade is approximately
24" in diameter. Replace the blades when the
diameter reaches 22" or performance is no longer
satisfactory.
Replace broken or cracked blades immediately.
Front blades will wear faster than rear blades. The
outer blades on the front gangs will wear faster
than the inner blades. Similarly, the inner blades
on the rear gangs will wear faster than the outer
blades. For best performance, keep all blades
approximately the same diameter.

DISK GANG SETTINGS

ADjUSTING GANGS.
The MAXIMUS disk gangs may be set at 0, 6,
14, 19, 24, or 29 degrees. The gangs may be
rotated forward or rearward to achieve a variety
of soil profiles. The gangs may also be moved
laterally on the frame, resulting in working widths
from 5'3" to 7'3" feet on 4-Blade units and 6'8"
to 8'8" on 5-Blade units. These adjustments
permit the disk to be used for normal disking,
reverse disking, and flat furrowing (Fig. 1-1, Fig.
1-2, and Fig. 1-3).
GANG ANGlE ADjUSTMENT
Remove the pin from the radius plate on the
gang. Flip the over-center cam handle to unlock
the gang.
With the machine lifted slightly off the ground,
spin the gang frame to the desired working
angle and reinstall the pin. Flip over-center
cam handle to lock the gang. Repeat on the
other 3 gangs.
If adequate clamping can't be achieved, adjust
the carriage bolt that passes through the trunnion
on the over-center cam handle by unlatching
the over-center cam handle and rotating counter
clockwise until square head of the carriage bolt
can be indexed 90 degrees in either direction.
Indexing the bolt clockwise looking (from above)
will increase the tension on the bolt and counter
clockwise will decrease the tension.
When locking and unlocking the over-center
cam handle an extension pipe is provided for
added leverage. To retrieve the extension pipe
from behind the center shank mount remove a
lynch pin from the pipe and remove pipe. Use
pipe as required then reinstall extension pipe in
frame tube and reinsert lynch pin for storage.
GANG lATERAl ADjUSTMENT
Remove both pins from the gang frame. Slide
the gange to the desired width and reinsert both
pins. Repeat on the other 3 gangs.
