ABSTRACT:
A machine and method of operation thereof to pick-up individual bales of hay or other forage material from the field to create a package of individual bales that is silage-wrapped with plastic before being discharged back to the ground. The receiving table is pivotally supported on the frame of the machine to provide the ability to re-orient the package for wrapping plastic about orthogonal axes. A clamping and elevating mechanism is operable to lift layers of individual bales to permit the formation of subsequent layers therebeneath until the desired package size has been completed. The clamping members are rotatably mounted to allow rotation of the elevated package for wrapping plastic around the periphery thereof. Ejection of the wrapped package is accomplished by pivoting the telescopic members mounting the clamping members to a horizontal orientation and releasing the package. The reversal of the discharge process can be utilized to retrieve wrapped packages from the field.
