发明名称 Folding furrow roller for the preparation of seed beds
摘要 A folding furrow roller that facilitates planting operations and optimization of irrigation and drainage with efficient preparation, configuration, and planting of seed beds. A centrally located fixed drum roller supports a pair of hinged outboard drum roller wings that for maximum implement width are deployed in alignment with the main section during operation. The wings are hydraulically folded into a compact upright position for legal transport over public roads. The implement is constructed so as to provide strength and durability comparable to single-section furrow rollers.
