An attachment [10] used in conjunction with a backhoe or track hoe [12] to convert it into a machine to unload ties [14] off of railroad cars [16]. Two pins [40] on an upper end [38] of the attachment [10] secure it to the distal end [22] of the working arm [24] of the backhoe or track hoe [12] so that a front edge [26] of the attachment [10] points toward the backhoe or track hoe [12]. Upper ends of [48] four c-shaped members [50] attached to an upper plate [46] on the upper end of [38] the attachment [10]. Opposite lower ends [52] of each of the four spaced apart c-shaped members [50] are flattened on upper and lower surfaces [54U and 54L] into a point [56]. A lower plate [57] is secured to the upper surfaces [54U] of the lower ends [52] of the c-shaped members [50] to form the front edge [26]. Support bars [58] secure between adjacent c-shaped members [50] and openings [60] are provided in the c-shaped members [50] to reduce weight while maintaining strength.
