Remove the blade bar boss (2) by undoing the M12 bolt
(3), illustrated in Figure 9. Using the blockage removal
tool, which is stored on the front of the machine, slide out
the blade beam by hooking the boss hole.
To obtain fresh cutting edges on the blades, the blade
beam can be fully removed from the machine and
replaced in the opposite direction.
After the blade beam has been inserted back into the
machine, replace the blade bar boss but do not tighten
the M12 bolt, this allows the blade position to be adjusted.
Check the blade clearances on the crossbeater by
removing the locking pins and lowering the sliding blade
carrier. Align the blades centrally between the
crossbeater rings by adjusting the blade beam tension bar
on the sliding blade carrier. Finally tighten the M12 bolt
securing the blade bar boss and reposition the cover.
Once both edges of the blades have become blunt the
individual blades will require replacement. Do this using
a 13mm ring spanner and a 6mm Allen key, both with
long handles, this will allow the bolts to be removed
whilst avoiding contact with the sharp edges of the
blades.
13.3 Bed Chain
To tension the bed chain, on both sides of the machine
release the front lock nut on the bed chain tensioner and
jack the mounting bush using the other nut. The bed
chain should be tensioned such that the chain can be
lifted 50mm above the bed midway between the front and
rear sprockets. Retighten the lock nuts.
The position of rear sprocket scrapers will stay the
correct distance and position relative to the rear sprocket
and do not need to be adjusted separately see Figure
10.
If the bed chain becomes tight in use, check that the
grooves in the front and/or rear sprockets have not
become tightly packed with straw or silage. If they have,
they will need clearing and the scrapers may have
excessive wear and need replacing.
Figure 10. Sprocket scraper position.
If the area beneath the bed chain becomes blocked or
requires attention, remove the bolted inspection panel
underneath the machine and clear the blockage.
As the links of the bed chain wear into each other
repeated tensioning of the bed chain results in the rear
shaft moving closer to the rear of the chassis. As this
happens the gap for stones and other obstructions being
brought around by the slats reduces making the bed
chain more likely to jam.
Figure 11. Dimension before shortening bed chain
When the bed chain is reaching maximum adjustment
then 2 links from either side of the chain will need
removing to extend the lifespan of the chain. The earliest
this can be done is when the distance of adjustment
shown in figure 11 has been reached.
To shorten, split the chain at any slat. Remove two links
from the same section of chain on the left and right hand
side, re
-
join and tension.
13.4 Bale Restraint Beam Adjustment And Removal
To adjust the bale restraint beam(s) remove the two M12
bolts located in the holes on both sides of the restraint
beam, and loosen the third bolt in the slot. Reposition
the bale restraint beam by aligning the necessary holes,
replace and tighten bolts.
To remove, take the weight of the bale restraint beam
using a suitable lifting device. Remove the 3 bolts from
each end before extracting the bale restraint beam.
Refitting is the reverse of above.
