MOWER BLADE SPEED CONTROL SYSTEM |
| 摘要 |
A mower blade speed control system with an electronic control unit providing engine speed commands to an internal combustion engine having a maximum power speed and a reduced economy speed, and a continuously variable transmission with variable displacement providing rotational power from the engine to a plurality of mower blades. The electronic control unit monitors engine load and automatically adjusts engine speed and the displacement of the continuously variable transmission in response to engine load to achieve a constant rotational speed of a plurality of mower blades at different engine speeds. |
