ultrasound sensor (bent

• A lot of feed at the end of a
feed fence can push an MFR
outwards, this may influence
the next route action(s)
• Prevent excessive build up of
(rest) feed. Stop the dosing
earlier (only done by service
technicians) or remove the
feed regularly.
• Missed reset point
When a MFR hits a wall past the
point where it should have
stopped on a reset strip it may
have started to look for the
reset strip too late or it may not
have recognised the strip. The
difference between detecting
steel and no steel must be big
enough for both sensors at the
same time to recognize a strip.
Reset strips should be as close
as possible and perpendicular to
the driving direction. Preferably
not more than 30 degree but
certainly not at a 45 degree
angle or bigger. If there is a lot
of feed on top of the reset strip
it could be that the MFR is
pushed to the middle and miss
the strip. Wet dirt or ice on the
sensors or strips influences the
measurement. Misalignment of
the sensors will make them
unreliable.
Manually reverse the MFR to a
position before the reset strip
and resume the route. Remove
feed which was buildup on top of
the reset strip. Clean the
inductive sensor unit and make
sure there is no metal under it.
Clean the sensor unit, make sure
the height adjustment of sensor
bracket is correct.
Ask your Lely Center to check if
sensors are positioned correctly
in their bag (not pushed
upward). Ask them to adjust the
wheel diameter when the MFR is
structurally to late in seeing the
reset points (increase diameter)
and let them improve unreliable
routes (positioning and use of
reset strips).
Feed falling from the inside Solution:
Preventive measure:
When feed dosed from the bin
cannot fall freely on the feed
alley, there can be a buildup
around the dosing roller that
eventually can push the whole
bumper outwards.
Clear the feed under the dosing
roller (see Clean the Dosing Roll
and Position Sensor on page 6-3)
and resume the route.
Aim to cut roughage as much as
possible during harvest. Make
sure the knives and mix settings
are optimal, consider lowering
the amount of feed (dosing
weight) for that location,
Consider to ask your Lely Center
to adjust the route to allow
more space for the feed to fall
(drive at a larger distance from
the feed fence).
