Abstract
A vehicle includes a blade, a lifting mechanism configured to raise and lower the blade, and a pitching mechanism configured to pitch the blade forward and backward. A control system of the vehicle is configured to automatically maintain at least one of a depth of the blade during pitching of the blade and a pitch of the blade during lifting of the blade.
Claims27
A vehicle including:
- a chassis;
- at least one ground engaging mechanism configured to support and propel the chassis;
- a blade coupled to the chassis;
- a lifting mechanism configured to raise and lower the blade relative to the chassis;
- a pitching mechanism configured to pitch the blade forward and backward relative to the chassis;
- and
- a control system programmed to operate the lifting mechanism, operate the pitching mechanism, and coordinate pitching and lifting of the blade to maintain at least one of a depth of the blade during pitching and a pitch of the blade during lifting.
