    摘要： A cultivator apparatus, for use on a motor vehicle, includes a blade-support/vehicle-connector assembly which includes a horizontally oriented base portion, blade connectors attached to the base portion for connecting to a blade assembly, and first vehicle connectors attached to the base portion for connecting to the motor vehicle. A blade assembly is connected to the blade connectors and extends downward from the base portion. The blade assembly includes a pair of downwardly descending strut members connected to the blade connectors and includes a horizontally extending scraper blade unit connected to the strut members. The blade-support/vehicle-connector assembly further includes a lift-link assembly supported by the base portion. The lift-link assembly includes housing walls connected to the base portion. A lower link-support pin is connected horizontally between the housing walls. An upper link-support pin is connected horizontally between the housing walls. A link member is supported between the housing walls by the lower link-support pin and the upper link-support pin. The link member includes second vehicle connectors. The upper link-support pin is a shear pin. The first vehicle connectors of the base portion include a first three-point-hitch-assembly connector located on a first side of the base portion and include a second three-point-hitch-assembly connector located on a second side of the base portion. The second vehicle connectors of the first link member provide a third three-point-hitch-assembly connector.
