ABSTRACT:
A depth control skid and seed boot assembly is disclosed that is particularly useful in a sod seeding implement for adjusting the maximum depth of cut of a cutting wheel and for adjusting the depth of the seed boot independently of each other. An arm rotatably mounting a pair of cutting wheels slidably receives the forward section of the skid. The rear of the skid is bolted to a bracket assembly vertically positionable with respect to the arm for adjusting the depth of cut. The bracket assembly pivotally carries the seed boot which is yieldingly and adjustably held in position with respect to the ground by a bolt and spring assembly. The seed boot can pivot upwardly against the bias of the spring out of the way of obstacles.
