发明名称 Cultivating apparatus for leveling, cultivating, and resowing lawns or fields
摘要 Cultivating apparatus for leveling, cultivating, and resowing lawns or fields. The cultivating apparatus includes: a row of ripping tines arrayed across the front of the apparatus, which are arranged to freely pivot forward and upward in use, to release clogged soil or other material by reversing, when necessary. A levelling plate is provided immediately behind the tines. An adjustment system is provided for an elongated horizontal rack of cultivating discs, by which the rack may be raised and lowered accurately and evenly at both ends, so as to maintain a correct, horizontal orientation. A corresponding adjustment system on an array of outlets from an elongated seedbox allows all the outlets to be opened or closed equally. The apparatus also includes pivotable seed dispensing spouts, a tilted mounting arrangement of the cultivating discs, which allows seed-dispensing spouts to be positioned over the widest part of cuts made by the discs, to drop seeds into the cuts in use, and a transverse roller at the rear of the apparatus behind the discs and seed outlets.
