Cleaning
After each mowing operation clean the
cutter bar thoroughly with water. To this end,
take off the knife to ensure any dirt collected
between the blades is removed. After clean-
ing, apply bio-lubricating oil or bio-lubricat-
ing grease to all gliding parts.
For longer storage, spray the cutter bar with
Bio-slushing oil.
Knife Driver Pin
Lubricate the nipple on the driver pin with
bio-lubricating grease at intervals of 25 op-
erating hours or once per year, depending
which period is completed first. Also lubri-
cate it each time the cutter bar is attached
and after each cleaning with a pressure
washer.
O-ring
Check and replace, if necessary, the o-ring
on the front end of the rocker arm each time
you maintain the cutter bar and when mount-
ing it to the machine (agria no. 722 76).
Carrier Pin
Grease the cutter bar carrier pin with bio-
lubrication grease each time you attach the
cutter bar and after each cleaning with a
pressure washer.
Setting the Knife Guiding Devices
To adjust blade protrusion (d) and play (g)
loosen clamping screws (c) and attachment
bolts (e) to change the position of the knife
guides accordingly. Ensure the individual
guiding parts are parallel. First tighten the
attachment bolts (e) and then the clamping
screws (c) very well (70 Nm) while you si-
multaneously press the knife holders in the
direction indicated by the arrow (f) using a
long ring spanner.
