McHale HS2000 Round Bale Wrapper
35
5.9.2 Setup (E)
1. Fit wrapper hitch to baler as appropriate. This will depend on the model of baler
to which it is being fitted.
2. Fit combined flow control/diverter valve in an appropriate position on the baler.
For example at the back end of the baler hitch (above pick up reel).
The diverter section is not used for this situation.
3. Select a double acting spool valve on the tractor (preferably with a detent to
hold the lever open in one position). This will be used for operating the rear
door of the baler and the wrapper.
4. Connect Port B on the flow control/diverter valve to the tractor spool valve, on
the side that will be used to send oil to the wrapper (spool valve upper).
5. Connect Port A on the flow control/diverter valve to a freeflow return to tank on
the tractor. Refer to your tractor manual to see where this is best achieved. This
freeflow is very important so that the working of the wrapper will not be
impaired. This is also used as the return for the wrapper.
6. Connect the baler rear door hydraulic hose to the same tractor spool valve (as
used on item no.4) to the opposite side that will be used to send oil to the
wrapper (spool valve lower).
7. Connect Port 2 on the flow control/diverter valve to the wrapper feed hose. This
ends at the wrapper hitch on the baler.
8. Port 3 is to be blanked off.
The system works as follows:
1. Move tractor hydraulic valve lever in one direction to open rear door.
2. Move tractor hydraulic valve lever in opposite direction to close rear door and
supply feed to the wrapper.
NOTE: The graduated flow control knob must be adjusted to give
an oil flow to the wrapper of 25-30 l/min, just enough to allow the
wrapper to work
The first symptom of low oil flow is that the cut and hold will not release
enough to catch the plastic at the end of the cycle.
