  • Patent number: 10876272
    Abstract: A control system for a machine may include a chassis an implement attached to the chassis, a first sensor, a second sensor, and a controller in communication with the first and second sensors. The first sensor may be configured to generate a first signal indicative of an angle of the implement with respect to the chassis. The second sensor may be configured to generate a second signal indicative of an angle of the chassis with respect to gravity. The controller may be configured to determine an implement mainfall angle based on the first signal and the second signal; process the second signal using a low pass filter to determine a filtered chassis pitch angle; determine a target mainfall angle based on the first signal and the filtered chassis pitch angle; and generate a command signal based the target mainfall angle and the implement mainfall angle.

  • Patent number: 7654336
    Abstract: A blade has an overall blade width of W, and includes a central front portion, interposition front portions, and side front portions. A straight first edge section is arranged on the lower end of the central front portion. Each of the front surfaces of the central front portion, the interposition front portions, and the side front portions is formed in an arc-shaped surface that has a prescribed radius R2. The radius R2 satisfies the following formula: R2=(0.7 to 1.0)×H, where H is the height from the edge of the first edge section to the top end of a soil retaining plate in side view in a digging posture when the edge angle ? of the edge sections is an angle of 40° to 55°.
