OPERATING THE PLANTER
DRILLING DISTANCES
Four sprockets are shipped with each unit; 11-, 14-, 20-
and 22-tooth sprockets. These sprockets will give the
seed spacing shown on the following page.
The 14-tooth sprocket (A) and 20-tooth sprocket (B) are
shipped in place. If other sprocket combinations are
desired, remove cap screw (C) and remove sprockets
from storage position.
APPROXIMATE DRILLING DISTANCE IN INCHES
NOTE: The 9-tooth sprocket is not available to order.
To obtain the one to one ratio, use two 14-tooth or two 20-tooth sprockets on the same planter. This
can be done by pooling the sprockets from two planters or by ordering extra sprockets.
The drilling distances may be doubled by using the extended distance attachment.
See Extended Drilling Attachment in the Attachment section.
In rough field conditions, reduce travel speed to insure proper seed plate cell fill.
Do not exceed the maximum plating speeds in the drilling distance chart or seeds will bounce out of
seed plate cells while planting. Vegetable plating also requires smooth seedbed preparation.
