Abstract
A mower slope sensing system on a grass mowing machine. An elevation sensor may capture terrain elevation values for each of a plurality of different locations according to a latitude and a longitude of each of the locations on a field. An electronic controller may store the terrain elevation values, latitudes and longitudes, and adjust a mowing blade speed depending on changes in the terrain elevation values from a current location to a next expected location.
Claims10
A mower slope sensing system, comprising:
- a grass mowing machine having an electronic controller storing elevation data for a plurality of different locations on a golf course or playing field, and having a global positioning sensor that senses a current location and a direction of travel of the grass mowing machine;
- the electronic controller determining an expected next location of the grass mowing machine based on the current location and the direction of travel, adjusting blade speed if the controller determines there will be a slope that exceeds a threshold from the current location to the expected next location, and adjusting blade speed based on an expected change in ground speed from the current location to the expected next location.
