Abstract A device mounted on a trailer or self-powered vehicle having a bin for receiving a supply of bales. A plurality of lateral, driven shafts adjacent the front of the bin carry knife assemblies for cutting and shredding baled hay or the like. A longitudinal conveyor on the bottom of the bin carries the bales into the knife assemblies. A plurality of leveling wheels are provided at the top and rearward of the knife assemblies for holding the hay in the knife assemblies as it is being shredded.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
141 words
A device for shredding baled material comprising: a. a bin for receiving bales to be shredded, b. a plurality of power driven rotating knife assemblies in said bin disposed one above the other and each including a cross shaft and radially extending knife blades projecting therefrom, c. conveyor means arranged to feed bales into said knife, d. a power driven cross shaft above the uppermost shaft of the knife assemblies, e. and a plurality of wheels on said last mentioned shaft, f. said wheels projecting radially beyond the uppermost knife blades with relation to the side from which the bales are fed by said conveyor means, g. said wheels being non-round so that their peripheral edges provide abutment for material which has worked up on the knife assemblies in a shredding operation whereby the material is held down for efficient shredding.
Claim 2
Independent Claim
141 words
