Abstract: Sod harvesting equipment is described which includes a cutting head with an undercutting knife and side rollers or knives. The cutting head is mounted such that it can tilt or rotate about an axis of rotation extending through the plane of the undercutting knife. The bearing arrangement eliminates the need for the undercutting knife to move sideways as the head progresses over uneven ground. The gage roller and the cutting head are allowed to work in complete conformance with the surface encountered to minimize scalping due to uneven terrain.
