  • Patent number: 4161253
    Abstract: A tractor-mounted carrier and dispenser for a cylindrical bale of substantial size and weight. The carrier includes a pair of cantilevered rollers spaced apart in parallel relation to hold a cylindrical bale thereon. The rollers are power-movable toward and away from each other to facilitate lifting a bale from the ground. The rollers are powered in rotation to rotate a bale thereon for progressively feeding hay from the bale onto the ground between rollers. The rollers are moved toward each other to continuously support the bale as it decreases in diameter. Controls permit the operator to vary the rotation speed of the rollers relative to each other to create a peripheral shreading or tearing action to enhance the feeding of the bale. The carrier of the invention is also readily capable of transporting a bale from point to point.
