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; a working arm mounted to the superstructure; a counterweight 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; wherein the superstructure comprises a bodywork portion having a first angled perimeter surface, an angle of the first angled perimeter surface being greater than 0° below a horizontal and less than 90° below the horizontal; wherein the first angled perimeter surface extends over at least a part of the bodywork portion of the superstructure and at least a part of the counterweight; the working machine further comprising an operator's cab mounted on the superstructure, wherein the counterweight comprises a surface abutting against the operator's cab, and wherein said counterweight surface comprises a recess for abutting against the operator's cab; wherein the superstructure comprises a second angled perimeter surface 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 angles of the first and second angled perimeter surfaces differ; and 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. ### Claim 2 (depends on 1) The working machine according to claim 1, wherein the drive arrangement includes a prime mover and a transmission. ### Claim 3 (depends on 1) The working machine according to claim 1, wherein the drive arrangement comprises a hydraulic motor. ### Claim 4 (depends on 1) The working machine according to claim 1, wherein the counterweight comprises an upper surface, a lower surface and an angled counterweight perimeter surface. ### Claim 5 (depends on 1) The working machine according to claim 1, wherein the bodywork portion is convexly curved in plan view. ### Claim 6 (depends on 1) The working machine according to claim 1, wherein the counterweight forms at least a part of the second angled perimeter surface. ### Claim 7 (depends on 1) The working machine according to claim 1, wherein the first angled perimeter surface and/or the second angled perimeter surface define a convexly curved surface. ### Claim 8 (depends on 1) The working machine according to claim 1, wherein the first angled perimeter surface and/or the second angled perimeter surface define a continuously curved surface. ### Claim 9 (depends on 1) The working machine according to claim 1, wherein the counterweight defines a segment of a circle in plan view. ### Claim 10 (depends on 1) The working machine according to claim 1, wherein a height of an upper extent of the counterweight is between a quarter and a third of a height of an upper extent of the operator cab. ### Claim 11 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; a counterweight mounted to the superstructure; a drive arrangement located in the base assembly for moving the ground engaging structure to propel, in use, the working machine, wherein the drive arrangement comprises a prime mover located in the base assembly; wherein the superstructure comprises a bodywork portion separate from and adjacent to the counterweight, the bodywork portion having a first angled perimeter surface, an angle of the first angled perimeter surface being greater than 0° below a horizontal and less than 90° below the horizontal, the counterweight comprising a mounting arrangement for the mounting of a heat exchanger thereon and defining an air flow path through said counterweight, the air flow path having an inlet and an outlet to permit air to flow through a heat exchanger when mounted thereon. ### Claim 12 (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 13 (depends on 12) The working machine according to claim 12, wherein the kingpost is proximate a front of the working machine. ### Claim 14 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; a counterweight mounted to the superstructure; a drive arrangement located in the base assembly for moving the ground engaging structure to propel, in use, the working machine, wherein the drive arrangement comprises a prime mover located in the base assembly, and wherein an entirety of the prime mover is located below a level coincident with a lower extent of the superstructure; wherein the superstructure comprises a bodywork portion separate from and adjacent to the counterweight, the bodywork portion provided as a housing for hydraulic systems, the bodywork portion having a first angled perimeter surface thereof, the angle being greater than 0° below a horizontal and less than 90° below the horizontal. ### Claim 15 (depends on 1) The working machine according to claim 1, wherein the operator cab defines an enclosable compartment comprising a wall abutting against the recess in the counterweight.
