Why were threshing machines opposed by the poors?

Threshing machines were opposed by the poor in England because they decreased the employment opportunities of workmen during harvest-time. Previously, labourers had lived with the landowners, doing odd jobs around the farm. Later, they were hired on wages and only during harvest-time. However, with the coming of the threshing machine, most of these labourers were left unemployed and without a means of livelihood. Hence, they opposed this industrial tool.
