Abstract
A machine for sheathing bales of material such as hay, straw and the like The machine has radially adjustable fingers to stretch a resilient sheath for the free insertion of the bales. The machine has elevating and guide mechanism for elevating and guiding the bales through the machine and as the bales exit the machine they are encased in the sheath. The resilient sheath will shrink to its original size to thereby fit closely to the contour of the bale. The machine has a swing away tow bar for offsetting the machine to either the left or right of the towing unit permitting the towing unit to travel on either side of the bale row. The swing away tow bar may be adjusted to a center position for ease of towing the machine from one job site to another or down a roadway. The swing away tow bar eliminates much of the side draft experienced previously.
