a working arm mounted to the superstructure; a connector connecting the undercarriage to the superstructure; and a drive arrangement located in the base assembly for moving the ground engaging structure to propel, in use, the working machine. ## Claims ### Claim 1 A working machine comprising: a base assembly including a ground engaging structure; an undercarriage connected to the ground engaging structure; a superstructure connected to the undercarriage, wherein the superstructure comprises a bodywork portion having a first angled perimeter surface thereof, an angle of the first angled perimeter surface being greater than 0° below a horizontal and less than 90° below the horizontal; a working arm mounted to the superstructure; a connector connecting the undercarriage to the superstructure; and a drive arrangement comprising a prime mover and a transmission, wherein an entirety of the prime mover is positioned below a level coincident with a lowermost extent of the superstructure, the drive arrangement for moving the ground engaging structure to propel, in use, the working machine, and a counterweight, wherein the counterweight forms at least a part of the first angled perimeter surface, wherein the working machine has a cab in a position offset from a center of the superstructure and the first angled perimeter surface is on a side of the machine remote from the cab. ### Claim 2 (depends on 1) The working machine according to claim 1, wherein the working arm is mounted to the superstructure using a kingpost arrangement in order to pivot relative to the superstructure about a vertical axis. ### Claim 3 (depends on 1) The working machine according to claim 1, wherein the machine has a cab and has a line of sight angle over a right hand rear corner of the machine for an operator seated in the cab having a height of 185 cm is at least 30° below the horizontal. ### Claim 4 (depends on 1) The working machine according to claim 1, wherein the connector is a rotary connector to permit rotation of the superstructure relative to the undercarriage. ### Claim 5 (depends on 1) The working machine according to claim 1, further comprising a linkage for connection to a working implement, wherein the linkage is configured to convert a substantially horizontal movement of an actuator into a substantially vertical arcuate motion of the working implement. ### Claim 6 (depends on 1) The working machine according to claim 1, wherein the first angled perimeter surface thereof comprises an angle greater than 10° below the horizontal and less than 80° below the horizontal. ### Claim 7 (depends on 1) The working machine according to claim 1, wherein the first angled perimeter surface thereof comprises an angle greater than 30° below the horizontal and less than 60° below the horizontal. ### Claim 8 (depends on 1) The working machine according to claim 1, wherein the superstructure comprises a second angled perimeter surface thereof positioned on an opposing side of the superstructure to the first angle upper surface, an angle of the second surface being greater than 0° below the horizontal and less than 90° below the horizontal. ### Claim 9 (depends on 8) The working machine according to claim 8, wherein the angles of the first and second angled perimeter surfaces differ, wherein the angle of the first surface below the horizontal is less than the angle of the second surface below the horizontal. ### Claim 10 (depends on 8) The working machine according to claim 8, wherein the counterweight forms at least a part of the second angled perimeter surface. ### Claim 11 (depends on 1) The working machine according to claim 1, wherein the undercarriage is at least formed in part from sheet metal material to define a space enclosed on at least three sides, wherein one of the at least three sides is located substantially above the space. ### Claim 12 (depends on 11) The working machine according to claim 11, wherein the undercarriage further comprising a mount for a first end of a linear actuator located within the space, such that the linear actuator is at least partially housed within the space, preferably wherein the linear actuator is configured to extend through an opening in a side of the undercarriage. ### Claim 13 (depends on 1) The working machine according to claim 1, wherein the undercarriage comprises a main chassis and at least one subsidiary chassis. ### Claim 14 (depends on 13) The working machine according to claim 13, wherein the main chassis comprises a mounting arrangement to mount the superstructure thereon and a mounting interface to mount the at least one subsidiary chassis thereon. ### Claim 15 (depends on 13) The working machine according to claim 13, wherein the subsidiary chassis further comprises an actuator to perform a work function, further wherein the actuator is housed within the subsidiary chassis. ### Claim 16 A working machine comprising: a base assembly including a ground engaging structure; an undercarriage connected to the ground engaging structure; a superstructure connected to the undercarriage; a working arm mounted to the superstructure; a connector connecting the undercarriage to the superstructure; and a drive arrangement comprising a prime mover and a transmission, wherein an entirety of the prime mover is positioned below a level coincident with a lowermost extent of the superstructure, the drive arrangement for moving the ground engaging structure to propel, in use, the working machine; and further comprising an operator's cab rotatably mounted on the superstructure by a rotary connection, wherein the superstructure is rotatable about a first generally upright axis and the operator's cab is rotatable about a second generally upright axis; and wherein the transmission comprises a hydraulic pump driven by the prime mover, a first high speed hydraulic motor to be supplied with hydraulic fluid from the hydraulic pump to drive a first axle to permit the working machine to be driven at relatively high speeds, and a second relatively low speed motor to be supplied with the hydraulic fluid from the hydraulic pump to drive a second axle at relatively low speeds. ### Claim 17 A working machine comprising: a base assembly including a ground engaging structure; an undercarriage connected to the ground engaging structure; a superstructure connected to the undercarriage, wherein the superstructure comprises a cab in a position offset from a center of the superstructure, a bodywork portion having a first angled perimeter surface thereof, an angle of the first angled perimeter surface being greater than 0° below the horizontal and less than 90° below the horizontal, a second angled perimeter surface thereof positioned on an opposing side of the superstructure to the first angled perimeter surface, an angle of the second angled perimeter surface being greater than 0° below the horizontal and less than 90° below the horizontal, wherein the angle of the first angled perimeter surface below the horizontal is less than the angle of the second angled perimeter surface below the horizontal, and wherein the first angled perimeter surface is on a side of the machine remote from the cab;
