The Beet Harvester is designed for simplicity and
trouble free operation. Art’s-Way Manufacturing Co.,
Inc. has provided a wide range of adjustments on this
machine to allow the best operation in various operating
conditions. It is essential that all adjustments be set for
your operating conditions. Continual review during
harvest must be done for optimum performance. When
field or crop conditions change, re-check your
harvesting operation and adjustments. The following
explains the operation and adjustment of the machine.
See your dealer if questions arise.

Figure 49 - Rowfinder Details
The rowfinder is adjustable to accommodate beet size,
beet height, operating depth and soil conditions. Correct
adjustment of the rowfinder and a good understanding
of the importance of each adjustment will provide
maximum satisfaction during field operation.
Make the following adjustments as necessary to meet
crop and field conditions before taking the machine to
the field.
NOTE: Be sure to raise the harvester when backing up
so the rowfinder is not damaged.
Feeler Arm Spacing
For this adjustment, the feeler arms (A) should be set so
the largest beets will just pass through the opening,
between the arms, remove the spring pins (C), set the
arms to the appropriate width, then install the spring
pins.
Feeler Arm Centering
The horizontal shaft (I) in the rowfinder must be parallel
with the front of the harvester frame to function
accurately. Remove the pin (F) and loosen the nuts (D),
then slide the plate (E) until the shaft is parallel with the
frame. Tighten the nuts.
The hydraulic control valve must be centered each time
the shaft (I) is adjusted. Loosen the lock nut (H) and
adjust the nut (G) until the pin (F) can be inserted freely
through the nut (G) and valve spool. Tighten the lock nut
(H) and make sure the pin (F) is still free.
The feeler arms must be centered with the gap between
the lifter wheels to function accurately. To adjust, loosen
the bolts (J) and slide the entire assembly on the tube
until they are centered. Tighten the bolts (J).
Rowfinder Height
Figure 50 - Distance between Bottom of Rowfinder
and Bottom of Lifter Wheel
The feeler arms should ride along the surface of the
ground or slightly penetrating the surface. Set the
rowfinder height in its correct relationship to the lifter
wheel working depth to assure proper function.
Example: If the lifter wheels will work at a depth of 3
inches [7.62 cm], the bottom edge of the feeler arms
