A method and system for removing material build-up in a mixing chamber of a rotary mixer machine. The system includes one or more actuators coupled to the mixing chamber and to a frame of the rotary mixer machine. Further, the system includes a controller configured to receive an input and activate the one or more actuators in response to the input to induce a forward and backward rocking motion in the mixing chamber to cause a dislodgement of the material build-up from the mixing chamber. The mixing chamber executes the forward and backward rocking motion between a first position and a second position about an axis disposed transversally to a length of the rotary mixer machine.

System and method for removing material build-up in mixing chamber of rotary mixer machine

In one aspect, a method for monitoring a milling machine having a milling rotor and a rotor chamber surrounding the milling rotor includes propelling the milling machine in a direction of travel, positioning a door of the rotor chamber at a first position with an actuator, and receiving a signal indicative of a condition of the actuator for positioning the door of the rotor chamber. The method further includes determining that the door has encountered material based on the signal and opening the door of the chamber in response to determining that the door has encountered material.

Systems and methods for surface milling

A milling machine, system, and method for implementing a return to cut operation and/or an exit cut operation controls legs of the milling machine, a rotor of the milling machine, and front and rear doors of a mixing chamber of the milling machine according to settings for each of the return to cut operation and the exit cut operation. Such control can be based on signals from one or more sensors of the milling machine configured to sense various position-related characteristics of the milling machine, and can be performed responsive to a control input at an operator control interface of the milling machine.

Machine, system, and method for work cycle automation

A rotor assembly for a rotary mixer is disclosed. The rotor assembly includes a main drive configured to rotatably drive the rotor assembly, a main drive clutch enclosed in a drivetrain housing of the main drive, an actuation valve operably coupled to the main drive clutch, the actuation valve configured to actuate the main drive clutch between at least a first position and a second position, a rotor drum, a rotor drive gearbox having an input and an output, the gearbox output operably coupled to the rotor drum, a main drive belt rotatably coupled to the main drive clutch and the rotor drive gear box input such that a rotation of the main drive clutch imparts a rotation on the rotor drive gear box, and a speed sensor operably coupled to the rotor drum, the speed sensor measuring a rotational speed of the gearbox and generating a rotor speed signal, wherein based on when the rotor speed signal is below a predetermined rotor speed threshold the actuation valve is activated to rotate the main drive clutch a predetermined amount between the first position and the second position.

Rotor assembly for resolving incomplete gear shift of a rotory mixer

An implement with a ground-engaging tool may include a frame supported above a surface of a ground by a ground-engaging portion and a suspension, a tool supported by and adjustable relative to the frame and configured for working the ground, a housing arranged around portions of the tool and secured to the frame, and a monitor system configured for identifying an exposed condition of the tool. A method of managing an exposed condition of a ground-engaging tool and a method of operating an implement with a ground-engaging tool are also described.
