Sod harvesting machine

A sod harvesting machine comprising, in combination, a wheeled frame having an elongated frame axis with opposed front and rear ends, at least one cutterhead at the forward end, a sod receiving wind-up saddle at the rear end, and an endless driven conveyor with a belt and at least one drive member extending therebetween, said conveyor belt having a top flight with forward-most, rearward-most, and intermediate segments, said forward-most segment receiving cut sod from the cutterhead to be advanced rearwardly for elevation and to said wind-up saddle for wind-up and discharge, and with said sod harvesting machine having cut-off means for intermittently severing cut sod for processing in defined lengths;

• said combination being further characterized in that:
• (a) said wind-up saddle comprises a laterally spaced apart pair of normally upwardly extending saddle arms pivotally attached to said frame and adapted for pivotal movement to form an adjustably expandable sod receiving wind-up saddle of generally “U” shaped configuration along said conveyor belt, said wind-up saddle having an axis generally transverse to said elongated frame axis;
• (b) said endless conveyor having belt supporting means including drive and idler cylinders, at least one drive cylinder and selected idler cylinders being disposed along said rearward-most segment and journaled for rotation within said upwardly extending saddle arms, activating means for pivotally moving said saddle arms for controllably delineating conveyor belt travel within said saddle for carrying lengths of incoming cut sod into said saddle to be helically wound into rolls directly from said conveyor belt;
• (c) said actuating means being coupled to said upwardly extending saddle arms for coordinated selective and adjustable pivotal movement of said arms relative to said frame means toward and away from said normal upwardly extending position for controlled movement between closed saddle, expanded saddle, and discharge saddle dispositions whereby expansion of the width of said saddle is provided while receiving, winding and discharging helically wound lengths of cut sod therefrom, with the expansion of said saddle accommodating the increasing radius of rolls of helically cut sod being wound from said defined lengths of cut sod.
