24 FIELD OPERATIONS
Paddle Assemblies
Figure 30 - Header Paddle Assembly.
The paddle assemblies push the harvested beets from
the lifter wheels to the header grab rollers. Mechanical
rotation of the paddle assemblies comes from the
harvester gearbox through a sprocket and chain drive
system.
The paddle assemblies are equipped with a split rubber
paddle. This allows each paddle to be narrowed or
widened for certain conditions. For example, in muddy
conditions the paddle can be moved to the open
position to help clean mud off the wheels.
The paddles also have two holes to adjust the length of
the rubber being exposed. The longer position will help
in muddy conditions as well as to help push small beets
back into the rollers.
NOTE: If the entire lifter wheel and strut assembly is
adjusted left or right (laterally), the paddle assemblies
and barriers must also be adjusted.
Conveyor Rollers
Figure 31 - Header Conveyor Rollers.
The conveyor rollers rotate rearward, pushing the beets
toward the center of the rollers and towards the short
conveyor.
The conveyor rollers are mechanically rotated using
both a belt and chain drive system.
If the poly rolls have been selected as an option, the
spacing can be adjusted to an open or closed position.
Poly rolls are set to the closed position at the factory. To
move the rolls to the open position, the outside bearings
must be rotated backwards and fastened into the new
bolt holes. On the 8R28/30 and 12R22, the center
bearing holders must be adjusted by rotating the
assembly up and towards the rear of the machine and
fastened in the new hole. (See Figure 32, Figure 33,
and Figure 34.)
The steel rolls leave the factory in the open position to
allow for more room for rocks to clear the rolls and are
not adjustable. The closed position does not allow
enough space for the rolls to float without hitting.
Rear Short Diverter Roll Options
Standard Rear Diverter Rolls
These rolls turn the same direction as the smooth and
four (4) spiraled conveyor rolls. These rolls push any
beets at the rear of the bed to the center of the machine.
Optional Rear Smooth Diverter Grab Rolls
These rolls turn the opposite direction of the front
smooth and four (4) spiraled conveyor rolls and act as a
grabroll. These rolls are used pull thru excess mud and
dirt from the conveyor roll bed so it doesn’t travel
through the short conveyor. These rolls are designed to
help control the windrow of mud that can form under the
harvester.
Header Drive Shaft
The header drive shaft is the primary means for
transferring mechanical power from the harvester’s
gearbox to the header. On the header, there are two
drive shafts per side. Each pair of drive shafts are
connected by a U-joint.
