4.4 REAR SEED PRESSING WHEELS
Alternatively to the rear seed covering harrow, the machine can
be fi tted with a number of rear seed pressing wheels (F, Fig. 59)
featuring built-in springs (G, Fig. 59) for covering the seed furrow.
The rear seed pressing wheels and springs are independently
adjusted (H-I, Fig. 59) to fi nd the best setup for seed furrow closing.
WARNING: During road transport, stop the wheel-carrying bar
using the supplied pin which has to be fi tted into the existing
holes (L, Fig. 59).
4.5 FLOATING FRAME WITH NITROGEN ACCUMULATOR
A fl oating system for the furrower holding frame has been incor-
porated in the planter: in specifi c ground conditions (valleys, hill
planting etc.), this system facilitates even planting of the seedbed,
despite its irregularity.
Install the mounting plates (M, Fig. 60).
During the normal planter setup procedures, the support wheels
have to be adjusted for height, varying the position of the pin (N,
Fig. 61), in order to align the furrower-holding frames and guarantee
an even sowing depth.
A nitrogen accumulator is supplied with the "fl oating toolbar kit" (O,
Fig. 62), to ensure that the side wings maintain a constant position
during planting.
The nitrogen accumulator's hydraulic system is equipped with a tap
which must stay open while the side wings are moving.
After the side toolbars have been opened, bring the nitrogen ac-
cumulator to a pressure of 30 bar (Max.), readable on the gauge
provided (Fig. 62).
Once this pressure has been reached, close the tap and proceed
with normal seeding operations.
