Field operation & machine adjustments
10.1 Break-in period
McHale
recommend a break-in period of approximately the first 50 bales or until the
paint within the machine has lost its shine. During this break-in period, the sides of the
bales may appear untidy, but once the side-walls have been polished smooth, then
bale sides should look neater. After the initial break-in period the tension of all the
chains on the machine should be checked and adjusted, as required
. Ensure that all grease points are adequately greased to prevent rapid
wear of components.
10.2 Swath preparation
An optimum baler performance of the machine requires a good swath preparation in
advance. The optimum swath width is 1.5 m
.
In the case where narrower swaths are unavoidable, it is recommended that the swath
be periodically directed 15 - 20 m to the right-hand side and also the same distance to
the left-hand side of the pick-up as the baler is driven over the swath.
Collect the material into one side of the pick-up for 6 - 8 seconds. Then cross over the
windrow and collect material for the same duration. Reduce the length of time for heavy
windrows and increase for lighter windrows.
Continuous weaving is not recommended as this will result in excessive material being
placed towards the centre of the bale.
In the case of wider swaths, i.e. >1.5 m; this size of windrow should be avoided, as in
this case a greater amount of material will continue to be fed to the outside of the baler.
As a result, a greater amount of material will be fed to the outer edges of the bale than
to the centre. This will result in concave-shaped bales.
NOTE: Swath width is the most important factor in proper bale
formation
A 1.5 m swath width provides optimum material flow into the bale
chamber for even bale formation. A swath width greater or less than
1.5 m will lead to increased bale deformation.
