Abstract

A forage handler adapted for mounting on a standard forage gathering device comprises a rotary head having protruding tines for dislodging forage from stacks and urging it toward the forage gathering device. The handler includes a support frame in which the rotary head is mounted, and a rotary beater or separator having teeth for breaking up large aggregations of forage and urging the same toward the forage gathering device. The support frame has a pair of booms which are pivotally connected to the gathering device and include motors to swing the rotary head into selected vertical orientations for dislodging the forage. The beater is positioned substantially parallel with and rearward of the rotary head, whereby the forage dislodged from the stacks by the rotary head is directed into the beater for flailing the forage to break up the large aggregations thereof, and urge the forage toward the gathering device.

A mobile handler for retrieving and processing stacked, unchopped forage, and adapted for attachment to a mobile forage gathering device, said handler comprising:

(a) a rotary head having a plurality of rigid, blunt tines protruding radially thereof for dislodging unchopped forage from stacks thereof;
(b) a first support frame having said rotary head rotatably mounted in a first end thereof;
said first support frame having a second end thereof shaped for pivotally connecting said frame with said forage gathering device, whereby said rotary head is positioned substantially transverse to and forward of said forage gathering device;
(c) first motor means operably connected with and rotating said rotary head;
(d) second motor means operably connected with and selectively pivoting said first support means with respect to said forage gathering device, and selectively swinging said rotary head into a plurality of vertical positions;
(e) a rotary beater having a plurality of rigid, blunt teeth projecting radially thereof for breaking up large aggregations of the unchopped forage which are dislodged from the stack by the rotary head;
(f) a second support frame having said rotary beater rotatably mounted in a first end thereof;
said second support frame having a second end thereof shaped for connection with said forage gathering device, whereby said rotary beater is disposed substantially transverse and forward of said forage gathering device, and said rotary beater is normally disposed below and rearward of said rotary head;
and
(g) third motor means operably connected with and rotating said rotary beater;
and
(h) cutter means for chopping up the forage;
said cutter means including rotary pick up tines which pick up separated, unchopped forage from the ground and convey the same to a chopper portion of said cutter means;
said cutter means being connected with said forage gathering device, and positioned directly rearwardly and in-line with said rotary beater, whereby unchopped forage is in sequence, dislodged from the stacks by said rotary head;
directed under gravitational forces into said rotary beater for flailing the unchopped forage to break up the large aggregations thereof and urge the separated forage into the cutter;
picked up from the ground by said rotary tines;
and cut into small segments by the chopper portion of the cutter means for transportation into the forage gathering device.
