CAUTION
Planter tank shall be filled at the stoppage, after lowering the planter onto the
ground, turning off the tractor engine and removing the key from the ignitron
switch.
CAUTION
Loading of potatoes to the tank shall be performed from means of transport (eg.
trailers).
CAUTION
All maintenance in the planter shall be performed before installing it on the tractor.
4.6. Mounting the planter on the tractor
When mounting the planter on the tractor, perform following activities:
- disassemble a tool drawbar from lower rods of the tractor three-point suspension system,
- drive to the machine frame close enough with the tractor,
- turn off the tractor engine, remove the key from the ignition switch and pull
handbrake,
- install tractor lower rods onto the planter studs and secure with typical cotter pins,
- using a pivot, link the upper connector of the tractor with the planter frame rack and
secure with a typical cotter pin,
- tighten gently chains of lower rods of the tractor, keeping the symmetry between the
planter suspension and the tractor,
- install portable light and warning signs and a triangular sing for low-speed vehicles.
CAUTION
It is forbidden to connect the machine with a tractor when the tractor engine is running.
It is forbidden to use other elements to secure the tool suspension system than
recommended by the manufacturer.
CAUTION
Keep extreme caution at connecting the planter, do not stay between the planter and
the tractor.
4.7. Adjustment and setting of the planter
Planter proper operation of good quality is dependent on proper levelling of the planter
and setting the planting depth, height of covering planted potatoes and the distances
between planted potatoes in a row.
Transversal levelling ensures determining equal depth of operation of right and left units of
the planter and is performed with the right hanger of the tractor suspension system. After
performing the adjustment, the planter tank, from the back view, is set horizontally after
gaining the full depth of operation.
Longitudinal levelling ensures determining equal depth of operation of working elements at
the front and back of the planter. Longitudinal levelling is performed by shortening or
lengthening the upper connector of the tractor suspension system. Properly levelled planter
should have the frame and the tank set in parallel to the field surface while furrow openers
and ridgers should operate at equal depth.
Adjustment of planting depth is performed by setting the proper height of front furrow
openers (at the same level) and setting their position with fastening bolts.
Adjustment of covering height is performed by setting the proper height of ridgers in lever
sockets and setting their position with bolts. All three ridgers should be on the same level.
Spreading movable wings of ridgers is performed by deflecting them and after setting at the
proper width they are locked with screw connections.
