Abstract
A sod harvesting machine travels forwardly along a path of travel and has a sod cutting head pivotally connected to a fixed rear frame by a horizontal front pivot shaft having its axis aligned along the path of travel and located close to the ground, and by a pair of rear pivots. The rear pivots are formed by a pair of curved tracks and rollers at the rear of the cutting head, well above the ground, allowing the front of a conveyor to be brought near the ground and close behind the sod cutting knife. The curved tracks have a common center of curvature located on the axis of the front pivot shaft so that they have the same effect as a horizontal rear pivot shaft located close to the ground and aligned with the front pivot shaft.
