1. A working machine comprising:
a ground engaging structure provided in the form of front and rear wheels or a pair of endless tracks;
an undercarriage supported on the ground engaging structure, the undercarriage comprising 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;
a working arm connected to the superstructure; and
a first implement mount connected the undercarriage for operably mounting a working implement to the undercarriage,
wherein the undercarriage comprises a first actuator for raising and lowering the 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
wherein the undercarriage comprises a first auxiliary hydraulic connector configured for supplying hydraulic fluid to the working implement connected thereto;
further comprising a second implement mount connected to an opposing side of the undercarriage relative to the first implement mount for operably mounting the working implement or an alternative working implement to the undercarriage, wherein the undercarriage comprises a second actuator for raising and lowering the working implement connected thereto when mounted to the second implement mount and comprises a second hydraulic connector for supplying hydraulic fluid to the second actuator to actuate the second actuator; and
wherein the undercarriage comprises a second auxiliary hydraulic connector configured for supplying hydraulic fluid to the working implement connected thereto, and wherein the second auxiliary hydraulic connector and the second implement mount are provided on the opposing side of the undercarriage.
