Abstract
Abstract A conventional loader vehicle having forward push arms with a bucket secured at their terminal ends is provided with a replaceable fork-type rake attachment including a rake member having a plurality of tines extending downwardly below the bucket. The rake attachment is pivotally mounted on the bucket and includes power means for manipulating the rake member toward and away from the bucket. A pair of rearwardly directed logsupporting arms is secured to the rake member to hold an object when the rake member is pivoted toward the bucket. A plurality of forwardly directed teeth are provided on the rake member to serve as gripping members to prevent it from sliding up the object to be moved when the vehicle is being used to push over small trees and the like.
