目前与中型拖拉机配套的驱动圆盘犁最后一个圆盘与左测板距离较大,当犁耕最后一行程时,会出现10～15cm未耕地,需人工耕翻。另外,其圆盘间距也较大,一般在250mm以上,致使粘土耕作时土垡块过大,沙土耕作时会出现波浪型漏耕带,对作物生长不利。 At present, the last disk of the driving disc plow matched with the medium-sized tractor has a large distance from the left test plate. When the last stroke of plowing is over, there will be 10 ~ 15cm uncultivated land, which needs artificial tillage. In addition, the disc spacing is also larger, generally 250mm or more, resulting in clay soil Clay block is too large, sand tillage wave-shaped tillage farming zone, adversely affect crop growth.
