Field Operations
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 to 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.

Grab Roll Option (12 Row 22 And 8 Row 30
)
The header drive shaft is connected to the harvester’s
gearbox. On the other end of the header drive shaft is
a sprocket with a paddle shaft slip clutch using a #80
roller chain. An idler sprocket between the drive shaft and
paddle shaft slip clutch ensures the chain is tight.
In addition there is a second chain drive system that
connects the full length grab roller to the smaller left-
hand diverter roller. As with the previous system, an idler
sprocket keeps the chain tight.
Header Mechanical Drive (Right-Hand Side)
Figure 34. – Header Right-Hand Drive
The paddle shaft is always driven from both sides with a
#80 roller chain. When the slip clutch needs to rotate in
the opposite direction, two additional idler sprockets have
been installed to route the chain properly.
The slip clutch is jaw type with steel rolls, and friction type
with poly rolls.
The 6 Row 30 and 8 Row 22 headers have full length
conveyor rollers which are belt driven from the right-
hand side only. The 8 Row 30 and 12 Row 22 headers
have conveyor rollers split in the middle which are belt
driven from both the left and right-hand sides. A gearbox
is required to reverse the rotation to the left-hand side.
A V-belt is routed around each grab roller belt sheave
allowing the mechanical power to be transferred from the
header drive shaft to each grab roller. A spring loaded
tension roller ensures proper belt tension is maintained.
Additional chain drives are required for the front smooth
or star roll and the left-hand diverter roll on the left-hand
side for the 6 Row 30 and 8 Row 22.
