A fine speed control associated with the coarse speed control of a vehicle, to select and maintain the speed of the vehicle. The fine speed control is interconnected to a coarse speed control in such a way that when disengaged it will linearly move in direct relationship to any forward or rearward movement of the coarse speed control. The improved speed control includes a connecting assembly for interconnecting the fine speed control to the coarse speed control, a main body portion, and a control lever operably associated with the main body portion. The control lever engages the main body portion in a manner such that the operator can, by moving the coarse speed control, temporarily and instanteously override the fine speed control without requiring disengagement thereof. The main body portion of the fine speed control includes expanding and contracting properties which permit automatic movement of an activator of a driver that drives the ground engaging portion of the vehicle. Stalling out or damage to the power source under increased power demands is effectively obviated by this automatic movement. |
