Abstract
Abstract A bale carrier comprising a first pipe having a second pipe selectively rotatably mounted therein with the ends of the second pipe protruding outwardly from the first pipe. The ends of the second pipe are pivotally connected to the rearward ends of a pair of lifting arms of a tractor three-point hitch apparatus. A tine is secured to each end of the second pipe and extends rearwardly therefrom for piercing engagement with the hay bale. A support frame extends upwardly from the first pipe and has a hydraulically operated cylinder mounted thereon which controls a pivotal hook arm extending rearwardly therefrom which is adapted to engage the upper portion of the bale. The support frame is pivotally connected to the rearward end of the third lifting arm of the three-point hitch apparatus.

Claim 1
Independent Claim
227 words
A bale carrier for use with a tractor three-point hitch having three lifting arms extending rearwardly therefrom comprising, an elongated first horizontally disposed support means, said first support means being transversely disposed with respect to the longitudinal axis of the tractor, a pair of tine members operatively secured to said first support means adjacent the opposite ends thereof and extending rearwardly therefrom for piercing engagement with the bale above the lower end thereof, first connection means for operatively connecting said first support means to two of the lifting arms, second support means extending upwardly from said support means, second connection means for connecting said second support means to the third lifting arm, an arm means pivotally secured to said second support means adjacent the upper end thereof and extending rearwardly therefrom, means on said arm means for engagement with the upper portion of the bale, means for selectively pivotally moving said arm means, said first support means comprising a first pipe means and wherein a second pipe means is selectively rotatably mounted in said first pipe means and has its opposite ends positioned outwardly of the opposite ends of said first pipe means, the two lifting arms being secured to the opposite ends of said second pipe means, one tine member of said pair of tine members being secured to each end of said second pipe means.
Claim 2
Dependent Claim
227 words
A bale carrier for use with a tractor three-point hitch having three lifting arms extending rearwardly therefrom comprising, an elongated first horizontally disposed support means, said first support means being transversely disposed with respect to the longitudinal axis of the tractor, a pair of tine members operatively secured to said first support means adjacent the opposite ends thereof and extending rearwardly therefrom for piercing engagement with the bale above the lower end thereof, first connection means for operatively connecting said first support means to two of the lifting arms, second support means extending upwardly from said support means, second connection means for connecting said second support means to the third lifting arm, an arm means pivotally secured to said second support means adjacent the upper end thereof and extending rearwardly therefrom, means on said arm means for engagement with the upper portion of the bale, means for selectively pivotally moving said arm means, said first support means comprising a first pipe means and wherein a second pipe means is selectively rotatably mounted in said first pipe means and has its opposite ends positioned outwardly of the opposite ends of said first pipe means, the two lifting arms being secured to the opposite ends of said second pipe means, one tine member of said pair of tine members being secured to each end of said second pipe means.
Claim 3
Dependent Claim
41 words
