Patent number: 11739496Abstract: A working machine includes a ground engaging structure, and an undercarriage supported on the ground engaging structure. The undercarriage has a drive arrangement for moving the ground engaging structure to propel the working machine, the drive arrangement comprising a prime mover and a transmission comprising a hydraulic pump arrangement configured to be driven by the prime mover. A superstructure rotatably mounted to the undercarriage and a working arm is connected to the superstructure. A first implement mount connected the undercarriage for operably mounting a working implement to the undercarriage. The undercarriage has a first actuator for raising and lowering a working implement when mounted to the first implement mount and comprises a hydraulic connector for supplying hydraulic fluid to the first actuator to actuate the first actuator, and a first auxiliary hydraulic connector is provided that is configured for supplying hydraulic fluid to an implement connected thereto.Type: GrantFiled: September 18, 2020Date of Patent: August 29, 2023Assignee: J.C. BAMFORD EXCAVATORS LIMITEDInventors: Duncan Andrew Smith, Patrick Edward Naylor
