Abstract
Abstract A front end loader on a tractor includes a bucket having a loading rake. A first arm extends upwardly and forwardly from the boom rearwardly of the bucket and is pivotly connected to a second arm extending downwardly and forwardly over the front of the bucket. A powered rotary cutting wheel is provided on the lower end of the second arm for raking silage or the like into the bucket. Individual power cylinders are provided for pivoting separately the first and second arms, the first arm being pivoted by a power cylinder extending between the first arm and the boom, while the second arm is pivoted by a power cylinder extending between the first arm and the second arm. Extension cutting wheels are provided for the outer ends of the rotary shaft on which the main cutting wheel is mounted to provide a cutting wheel corresponding to the width of the bucket.
