Abstract
Abstract A novel self propelled "big bale" stacker and retriever capable of stacking 4 by 4 by 8 foot, 3 by 4 by 8 foot, or pairs of 2 by 3 by 8 foot bales in 8 by 8 foot stable, tied units is presented. The stacker of the present invention utilizes a novel "jaw"-like arm that clamps onto a bale lying in a field. The arm swings up vertically and deposits the bale on a rotatable horizontal platform. The rotatable platform rotates 180 degrees to make room for a second bale next to the first. After two bales have been loaded onto the rotating platform, the platform tilts up 90 degrees to deposit the bales on the stacker's bed. By rotating the platform 90 degrees before depositing the bales on the bed, the orientation of the bales in successive tiers can be alternated so as to produce stable, "tied", 8 by 8 by 16 foot stacks.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
132 words
A stacker for picking up bales from a field comprising: a chassis; a load bed mounted on said chassis; a loading platform disposed on said chassis for receiving bales and for transferring bales received to said load bed; said platform including a turntable for receiving a first bale; displacing the first bale for reception of a second bale; and orienting said bales for transfer to said load bed; and a pick-up arm for picking up a bale, said arm pivotably attached by first pivot means to the chassis, adjacent to said loading platform, the first pivot means being disposed such that pivoting the pick-up arm about the first pivot means allows bales that have been picked up by the pick-up arm to be deposited directly on said turntable of said loading platform.
Claim 2
Dependent Claim
132 words
A stacker for picking up bales from a field comprising: a chassis; a load bed mounted on said chassis; a loading platform disposed on said chassis for receiving bales and for transferring bales received to said load bed; said platform including a turntable for receiving a first bale; displacing the first bale for reception of a second bale; and orienting said bales for transfer to said load bed; and a pick-up arm for picking up a bale, said arm pivotably attached by first pivot means to the chassis, adjacent to said loading platform, the first pivot means being disposed such that pivoting the pick-up arm about the first pivot means allows bales that have been picked up by the pick-up arm to be deposited directly on said turntable of said loading platform.
