Summary

In field and wind tunnel experiments in 1988 at the Scottish Centre of Agricultural Engineering, moisture loss in the 24 h after cutting increased when grass swaths were mixed, spread or turned and was positively related to the number of mixings. In the field trials, dry matter loss from conditioned swaths increased when the swaths were mechanically mixed or spreadafter cutting.
