A combined hand and foot control for a prime mover throttle member l0 including a hand control l2, a foot control l3, and a combining device l4 for combining the hand and foot controls. The combining device includes a plastics support housing l4a,l4b and a combining member 34 slidable within the housing in first and second opposite directions. A first cable linkage means connects the combining member 34 with the throttle member l0 so that movement of the combining member in the first direction moves the throttle member towards a fully open position, bias means 38 acting to bias the throttle member towards an idle position and hence bias said combining member 34 in the second direction via the first linkage l7. A second cable linkage l6 connects the foot control l3 and combining member 34 for movement of the combining member in the first direction, and a third cable linkage l5 connects the hand control l2 with the combining member 34 via a connection l5c,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 l5. The arrangement is such that any throttle member position set by the hand control l2 can be increased using the foot control l3 by the second linkage l6 sliding the combining member 34 in the first direction relative to the third linkage l5. |
