A sheet metal shutter 1 is mounted inside
the cover B. This shutter regulate the flow of
seeds coming from the hopper and provide a
constant and sufficient level in front of the
disc. According to the seed used, the shutter
as to be checked and adjusted at 2 different
positions before planting:
1. High position : For large seeds such as
corn , soybean, edible beans, peanuts,
cotton, etc.
2.Low position (fig.35) : For small seeds
such as sunflower, beet, sorghum, etc.
This position should also be used for large
seeds when the planter has to work for
several hundred meters (1000 or more) on
slopes of more than 20%.
The shutter is adjusted by lowering it after
loosening the two bolts 2. A small plastic
sheet 3 located under the shutter is also
used to limit the level of seeds in front of the
disc .
Before beginning your season, make sure
that it is in good condition.
A special metering box cover with a larger
opening (to improve the seed flow into the
seed chamber), a large discharge channel
(to avoid blockage) , and a special less
aggressive seed scraper (to avoid skips) are
available for the planting of large seeds such
as peanuts, kidney beans and large squash.
A special metal shutter is available for
planting small seeds such as cabbage ,
rape seed, etc. to reduce the seed flow into
the seed chamber.
A special ejector block maybe needed to
eliminate bridging in the discharger channel
in the cover for large peanuts and large
squash seed.
The ejector block 4 enables the seeds to fall
regularly. For this purpose, it is
recommended to check its conditions
periodically.
