  • Patent number: 3982711
    Abstract: A sod laying machine has a body portion connected with a pulling vehicle and mounted on an inflated cylindrical ground engaging roller. A plurality of rolls of sod are supported on the body portion rotatably in axial adjacency by a group of freely rotating rollers. Pairs of conveyor belts, that have spaced metal cross members flexibly connected by links, extend around upper and lower rollers in the body portion to incline rearwardly downwardly from the entrance ends to the discharge ends thereof. The upper rollers are driven from the ground engaging roller and have projecting lugs engaging the cross members to positively drive the belts. Rotatable feeding members engage the sod rolls to transfer lengths of sod from the rolls to the entrance ends of the paired belt conveyors and the feeding members are driven through ratchet means from the conveyor driving means, the ratchet drive permitting manual rotation of the feeding means independently of the driving means.
