发明名称 Transmission control systems
摘要 A transmission control system, such as for a self-propelled, walk-behind lawn mower, is provided for controlling first and second hydrostatic transmissions in which each one of the transmissions has a hydraulic dump actuator and a brake actuator. The transmission control system includes a control lever and a linkage. The linkage is engaged with the control lever, the hydraulic dump actuators, and the brake actuators of the first and second hydrostatic transmissions. The control lever and the linkage have a drive position which place both of the hydraulic dump actuators in a drive mode, a neutral position which place both of the hydraulic dump actuators in a neutral mode, and a brake position which place both of the brake actuators in a brake mode. The transmission control system can have a shift slot pattern which defines the drive, neutral, and brake positions of the control lever.
