Logging or sawmill operations on a farm undertaken on behalf of the
farmer or on behalf of the buyer of the logs or the resulting lumber by
a contract logger or sawmill owner are not within the scope of
agriculture unless it can be shown that these logging or sawmill
operations are clearly incidental to farming operations on the farm on
which the logging or sawmill operations are being conducted. For
example, the clearing of additional land for cultivation by the farmer
or the preparation of timber for construction of his farm buildings
would appear to constitute operations incidental to ``such farming
operations.''
