4.10.2.2 Working speed
The tractor engine speed/oil flow should be
adjusted to achieve
approx. 540 revs/min on PTO shaft while
baling
and 50 revs/min of the prestretcher ring while
wrapping (with warm oil).
If oil flow exceeds this level, there will be no
further speed increase of pre-stretcher due to
the flow restrictor integrated in the spool
valve block.
When processing silage bales, it is of great
importance to make high density bales. Re-
duce forward speed in high yield crops.
4.10.2.4 Driving
Make sure that the bale chamber is filled with
crop optimally to make the most of the bale
processor’s capabilities. Uneven filling of the
chamber can result in a conical bale, which
can tip sideways when the top section opens.
The chamber is filled evenly by driving in a
suitable way, i.e. driving alternately on the left
and right-hand sides of the swath when the
swaths are middle-sized or small.
When riding over big swaths, be aware of the
risk of heaps to form due to crop becoming
caught up.
When turning sharp corners, e.g. when turn-
ing round, make sure that no deviation is
greater than 80º on the wide-angle of the
universal drive shaft (on the tractor). Other-
wise there is a danger of breakage during
operation or when at a standstill.
The regular lowering of pick-up brings pick-up
hydraulics into floating position (frame around
joystick symbol), which is important to obtain
the best possible ground contour following.
Following guidelines will reduce the risk of
bale stopping when baling in straw and hay:
Drive straight ahead in the swaths, do not
drive alternately on the left- and righthand
side of the material.
Move the cutter blades out at 90% cham-
berfilling (USER setting)
Mount low friction sideplates in the bale-
chamber. Part no.: UH44070
Fit the straw baling kit on the machine.
Part no.: UH44078 (only available for SN:
4000325 and up). For earlier machines a
’teardrop’ tube is available. Part
no.:VF16650304
To avoid too much expansion of the bale, 4
layers of net is recommended as a minimum
for straw baling.
Note:
Material density and bale shape is improved
if you reduce the driving speed during the last
seconds of the baling sequence.
Lifetime of PTO clutch is increased when
reconnected at low engine speed.
