| With an average weight per foot of
450 lbs., the 4490 is heavy weight by competitive
standards. The 4490 is available in either 8" or
9" spacings, sizes ranging from 24 ft. to 32½ ft.,
with a narrow transport width of less than 12 ft. |

|
|
| A rephrasing hydraulic
lift system is standard equipment
on all 4490 discs. Depth stop segments c/w
holder (main frame lift cylinder only) are
supplied with each disc to ensure continuous
same-depth tilling. Each of the wing frames
can be easily leveled using a conveniently
located eye-bolt adjustment. Cylinder arms
on each of the rockshafts are equipped with
replaceable hardened wear bushings for prolonged
trouble free performance. |
|
| Slip-in spindles are
standard on our 4490 main and wing frame wheels.
All spindles are designed for maximum strength
and ease of removal. Simply remove one bolt and
pull out the axle – a valuable time saving
should a tire repair be required. |
|
| All 4490 Discs fold
hydraulically to narrow transport widths. The
4490 features a narrow center frame that allows
it to fold to less than 12ft. Hydraulic lockout
values are supplied standard to prevent accidental
operation of the lift and wing-fold circuits
when the disc is being transported. |
|
| Staggered overlapping
front gangs are standard on all 4490
discs. This feature ensures that the ground
is cut cleanly and evenly by the front gangs
thereby eliminating ridging problems at the
center. Also eliminated is the need for a center
shank normally supplied with conventional tandem
discs. |
|
|
|
| |
|
|
| Forward – action
wheel legs on the wings promote a level
field finish by reducing ridging or gouging in
the field. No need to add expensive and troublesome
gauge wheels. |
|
|
| All 4490 Discs feature a rugged
all-welded frame constructed of 4” x 4” high
tensile tubing. Critical fore/aft beams
on both the main and wide wing frames are doubled
for additional strength. |
