6.11 Scrapers
Scrapers keep the Lifter Wheels clean by removing mud and dirt off the wheels. In turn, the Lifter
Wheels are able to turn freely and lift beets.
Amity lifting struts are available with two types of scrapers, top or bottom. Bottom scrapers come
standard with the Single Plate Strut. Top scrapers come standard on the Double Plate Strut.
6.12 Paddles
Paddles are designed to transfer beets from the
lifter wheels onto the apron chain.
Two types of paddles are available for your Ami-
ty beet harvester. Rubber paddles are required
when using rock struts to lift beets and work
well in standard soil conditions. Plastic paddles
are available for better cleaning action in heavy,
clay
-
based soils and cannot be used with rock
struts. Figure 6

10 shows the two styles of pad-
dles.
Sections 7.8 and 7.9 have information regarding
adjustments for paddles and the paddle shaft.
6.13 Apron Chain
The apron consists of several parallel sets of chains. The
apron provides the first system to remove dirt, clods, and
debris from the beets. See section 7.10.1 for proper apron
chain tension.
