Bomet S239 - Work with a Planter

- 19 -
Adjustment of shaking device is performed by proper spreading shock finger and locking it
with screw connections so that after crossing of the finger there is only one planted potato in
the bucket.
Adjustment of spring strut of soil resistance is performed by the proper tension of the
spring so that the distance between neighbouring spring coils equals maximum 3 mm.
Setting the distance between planted potatoes in a row is performed by the change of
road wheel diameter. In order to do this units of the clamp shall be attached with screws in
one of three openings in brackets of the road wheel hub disc (in all units equally). As a result
of this adjustment, road wheels can gain diameter of 470mm, 520mm, 570mm and
various distances of planted potatoes in a row of 29, 32 and 35 cm are gained respectively.
WARNING
It is forbidden to perform adjustment of the planter at the tractor engine working. It is
forbidden for the operator to stay between the tractor and the planter at the tractor
engine running.
4.8. Work with a planter
The field intended for planting potatoes should be prepared in accordance with
agronomic requirements, furrows after ploughing should be levelled. The field surface should
be equal and deprived of weeds as plant remnants clog raking and ridging tools.
Properly mounted and adjusted automatic conveyor planter should move equally after
the tractor during operation and keep equal depth at the whole working width. Working speed
of the planter should equal maximum 4 km/h.
Planting, after performing adjustment of row spacing and operation depth, can be
started with an optional field edge. If the operation is performed on a slope, activities shall be
started each time from the above so that the extreme row could be copied during the return
crossing. First rows shall be performed as carefully as possible since precision of
performance of further rows, simplicity of performance of later cultivation treatment and
mechanical harvesting of potatoes depend on it.
At clogging of furrow openers or ridgers it is necessary to stop the tractor, raise and
lower the planter on the tractor hydraulic elevator.
CAUTION
It is not allowed to use tractor reverse gear during work, when the machine is in the
working position. The planter shall be raised easily, without jerks or vibrations.
CAUTION
Returns shall be performed easily with the planter raised to the transportation position,
without the use of an independent tractor brake. It is necessary to keep extreme caution
if there are people or items in the range of the planter operation.
WARNING.
All clogging made during operation of the planter requiring interference in the operation,
shall be removed after stopping the tractor, lowering the planter, turning off the tractor
engine and pulling the handbrake.
CAUTION
It is inadmissible to leave the planter on the slope or other terrain slope without securing
it against automatic rolling down.
