摘要:
The present invention relates to an agricultural implement (10) for cultivating an agricultural work area, the agricultural implement (10) comprising a main frame (12) being transferable between an operating position and a transfer position and a first subframe (20) connected to the main frame, the first subframe being transferable between and operating position and a transfer position. A main frame hydraulic cylinder (36) and a first subframe hydraulic cylinder (74) are provided to move the main frame and the first subframe between their corresponding positions. In order to provide correct and repeatable positioning of the first subframe hydraulic cylinder, a volume of a first chamber (114) of the main frame hydraulic cylinder (36) is substantially equal to a volume of the first chamber (124) of the first subframe hydraulic cylinder (74) when the first subframe (20) is in its operating position.
