A combined hand and foot control for a prime mover throttle member 10 including a hand control 12, a foot control 13, and a combining device 14 for combining the hand and foot controls. The combining device includes a plastics support housing 14a,14b and a combining member 34 slidable within the housing in first and second opposite directions. A first cable linkage 17 connects the combining member 34 with the throttle member 10 so that movement of the combining member in the first direction moves the throttle member towards a fully open position. A spring 38 act to bias the throttle member towards an idle position and hence bias the said combining member 34 in the second direction via the first cable linkage 17. a second cable linkage 16 connects the foot control 13 and combining member 34 for movement of the combining member in the first direction, and a third cable linkage 15 connects the hand control 12 with the combining member 34 via a connection 15c,35a capable of moving the combining member in the first direction only and allowing sliding of the combining member in the first and second directions relative to the third linkage 15. The arrangement is such that any throttle member position set by the hand control 12 can be increased using the foot control 13 by the second linkage 16 sliding the combining member 34 in the first direction relative to the third linkage 15.
