A milling system for a milling machine includes at least one cutting assembly configured to be coupled to a drum. Each of the cutting assemblies includes a base portion and an impact portion. The base portion includes a standoff coupled to the drum, a first base block coupled to the standoff, and a second base block coupled to the standoff at a position upstream of the first base block in a direction of rotation of the drum and at angle from the first base block. The impact portion includes a cutting bit and a tool holder coupled to the first base block, and a protective element coupled to the second base block.

Milling systems and methods for a milling machine

A rotary mixer includes a frame. The rotary mixer also includes a milling enclosure supported by the frame. The milling enclosure includes a side plate. The rotary mixer further includes a rotor disposed within the milling enclosure. The rotary mixer includes at least one vibration device coupled to the milling enclosure. The at least one vibration device is arranged to induce vibrations in at least one component of the milling enclosure for resisting accumulation of debris on the at least one component.

A method for determining part wear, such as using a wear model, includes receiving, from a sensor, sensor data representing a surface of a wear part. The method further includes determining an estimated time until the part should be replaced. The method further includes batching together multiple wear parts that need replacing to enable a user to replace multiple parts in one maintenance period. The method may also include providing information to the user during replacement of a worn part to indicate the part location.

Methods and systems for tracking milling rotor bit wear

A milling machine may include a frame. The milling machine may include a first wheel and a second wheel connected to a first end of the frame, and a third wheel connected to a second end of the frame. The milling machine may include a first leg, a second leg, and a third leg connecting the frame and the first wheel, the second wheel, and the third wheel, respectively. The milling machine may include a pair of arms pivotably connected to opposite sides of the frame. The milling machine may have a milling drum rotatably connected to the arms with a rotational axis parallel to the pivot axis. Further, the milling machine may have an engine that rotates the milling drum via a transmission. An output shaft of the engine positioned transverse to the frame may have an output shaft axis spaced apart from the pivot axis of the arms.

A milling assembly includes a drum housing including a discharge port; a cutting rotor located within the drum housing; and a flow director positioned within the drum housing proximate the discharge port and configured to direct a flow of material removed by the cutting rotor towards a first stage conveyor positioned near the discharge port.

A seal system for a rotor assembly of a surface treatment machine includes a rotatable rotor assembly shell including surface treatment tools extending therefrom, and a stub-shaft located within the shell and fixedly coupled to the shell. The stub-shaft includes a shaft portion and a base portion, with the base portion including a recess. A non-rotatable bearing housing surrounds at least a portion of the shaft portion and has an longitudinally extending inner end located within the recess. A seal member is located in the recess and secured between the bearing housing and the base portion.

Sealing system for a surface treatment machine

A rotor position indicator system may include a side plate and a first rotor width indicator plate. The side plate may be positioned on a side of an earth moving milling machine, and the first rotor width indicator plate may be inset on an external face of the side plate. The first rotor width indicator plate may include a plurality of markings, with each marking corresponding to a rotor position.

Rotor position indicator system

A machine having a ground-engaging rotor may include a first swing arm and a second swing arm. A first end of the first swing arm may be pivotably coupled a frame of the machine at a first pivot and its second end may be coupled to the rotor. A third end of the second swing arm may be pivotably coupled the frame at a second pivot and its fourth end may be coupled to the rotor. A torsion bar and a crossbeam may both be coupled to the first swing arm and the second swing arm. At least one actuator may also be coupled to the crossbeam such that activation of the at least one actuator rotates the first swing arm about the first pivot, and the second swing arm about the second pivot, and deploy the rotor.
