3.19.1 CLEANING TABLES
EZ Roll Table:
The EZ Roll Table is installed at the top of the side elevator
and provides a series of counter rotating rollers. Different
styles and size of steel and rubber rollers are optionally
available. The EZ Roll table works best in conditions with
clods.
During operation, the EZ Roll table (See Fig. #43) has ad-
justments to meet varying field conditions. These adjust-
ments include fingertip speed control of the cleaning rollers
and incline angle at which the best separation occurs. The
EZ Roll table is hydraulically driven utilizing the tractor hy-
draulic system. The speed at which the cleaning rollers run
has a direct relationship to its cleaning ability. The flow con-
trol valve on the tractor controls the cleaning roller speed.
The hydraulic cylinder controls the incline of the table from
a 3 degree downward tilt to approximately 10 degree down-
ward tilt. The operator controls the table’s roller speed and
incline angle that will produce optimum cleaning efficiency.
The EZ Roll table works best in mature round variety pota-
toes with the vines killed prior to harvest, which allows the
skin to toughen. The table works best with heavy soils that
tend to form clods. Supplementary irrigation is advisable if
available to pre-condition the soil for easy breakup. The EZ
Roll table installs into the tractor hydraulic system. To in-
sure proper application, consult the manufacturer’s specifi-
cations of the tractor model used.

Star Table:
The star table cleaning device (See Fig. #44) is installed at
the top of the side elevator and provides a series of soft
rubber finger rollers for trash and clod removal. This table
works well when used in trashy, cloddy conditions where
the soils are sticky to sandy. The star table will remove dirt,
small clods and trash.
The interlocking stars clean themselves in most conditions.
Several adjustments are available to enhance the cleaning
capability of the star table. To remove materials, adjust spac-
ing between the stars. Loosen the idler sprockets on the
drive chain. Locate the square bolt at the end of the star
table frame. Using a 5/8" wrench, turn the square bolt to
adjust the stars. Turning it clockwise will spread the stars
out. Turning it counter-clockwise will allow the stars to close
together. Both sides should be adjusted evenly. After ad-
justing the stars, reset the idlers so the drive chain is the
correct tension.
