A milling assembly for a cold planer including a frame and an actuator assembly having a plurality of movable locking rods for mounting the milling assembly to the frame is disclosed. The milling assembly comprises a drum housing, and a plurality of mounting units fixed to the drum housing for mounting the milling assembly to the frame. The mounting units include a plurality of mounting holes configured to receive a respective end portion of one of the plurality of movable locking rods. In another embodiment, a milling assembly including an actuator assembly with movable locking rods is disclosed.

A ventilation system and method for a cold planer are provided. The ventilation system includes a settling box inside a water tank. The settling box includes a body. The body includes at least one sidewall defining an air inlet having a first cross-section to accept dust and fumes generated by a milling drum operation of the cold planer but to reject particles from the milling drum operation at or above a predetermined size. The settling box further includes an air outlet having a second cross-section less than the first cross-section of the air inlet. The ventilation system further includes an outlet pipe connected to the air outlet, a fan and a cleaning system. The fan is configured to pull air from below the air inlet into the settling box, through the air outlet and to the outlet pipe.

A milling machine includes a frame, a ground-engaging rotor assembly coupled to the frame, and a rotor chamber surrounding the ground-engaging rotor assembly. The rotor chamber includes a moldboard having a top, a bottom, and two sides positioned between the top and the bottom, and the moldboard further having an open position and a closed position. The rotor chamber also includes at least one movable pin secured to the moldboard, the pin being movable by an in-line actuator between a pin extended position and a pin retracted position. Further, the rotor chamber includes a rotor chamber frame wall having an opening located to receive the pin when the pin is in the extended position and the moldboard is in the closed position, and the receiving of the pin in the rotor chamber frame wall opening secures the moldboard from movement.

Disclosed is an anti-slab height control system and related method for regulating the elevational position of an anti-slab mounted to a cold planer configured for milling a roadway. The cold planer includes a milling drum. The system comprises an anti-slab, a position sensor, a controller and an actuator. The controller is configured to determine an actuator adjustment based on a predetermined height, position data and a cutting depth of the milling drum. The position data is indicative of a current elevational position of the anti-slab. The actuator is configured to move the anti-slab based on the actuator adjustment from the current elevational position to a first elevational position, wherein the bottom side of the anti-slab is disposed at the predetermined height above the roadway when the anti-slab is in the first elevational position.

Cold planer exhaust systems and methods of clearing the same are disclosed. The exhaust systems and methods may include an inlet manifold located proximate a milling drum housing and above a material conveyor. The inlet manifold may further include at least one inlet passage and at least one access door configured to open and allow access to an interior of the exhaust system. The systems and methods may further include a ventilator configured to draw dust and fumes into and through the exhaust system.

Cold planer exhaust system with access doors

A transmission system is provided for transmitting power from an engine to a milling rotor in a cold planer. The transmission system includes a first circuit, a second circuit, and a shaft. The first circuit is disposed in a first plane and configured to be operatively driven by the engine. The second circuit is disposed in a second plane substantially parallel to the first plane and configured to operatively drive the milling rotor. The shaft couples the first circuit to the second circuit wherein the engine and the milling rotor are axially offset.
