         5 . The cold planer of  claim 2  comprising a mounting bracket slidably coupled to the frame adjacent to the rear end thereof and moveable in a vertical direction to move the rotary broom between the first position and the second position. 
     
     
         6 . The cold planer of  claim 5  comprising an articulation member movably coupled to the mounting bracket, the articulation member configured to couple with the rotary broom. 
     
     
         7 . The cold planer of  claim 1 , wherein the rotary broom is actuated by a hydraulic system of the cold planer. 
     
     
         8 . A cold planer comprising:
 a frame;   a set of ground engaging members disposed adjacent to a rear end of the frame;   a rotor disposed adjacent to the set of ground engaging members and configured to engage with a work surface;   a rotary broom operatively coupled to the frame adjacent to the rear end thereof and disposed behind the rotor to sweep residual material from the work surface; and   a carriage system pivotally coupled to the frame and disposed above the rotary broom, the carriage system configured to carry an operator to control an operation of the cold planer.   
     
     
         9 . The cold planer of  claim 8 , wherein the rotary broom moves to a first position relative to the frame when the rotor is distal from the work surface and moves to a second position relative to the frame when the rotor is engaged with the work surface. 
     
     
         10 . The cold planer of  claim 9 , wherein in the first position, the rotary broom is raised above the work surface. 
     
     
         11 . The cold planer of  claim 9 , wherein in the second position, the rotary broom is in contact with the work surface. 
     
     
         12 . The cold planer of  claim 9  comprising a coupling arrangement disposed between the frame and the rotary broom, the coupling arrangement comprising:
 a mounting bracket slidably coupled to the frame adjacent to the rear end thereof and moveable in a vertical direction to move the rotary broom between the first position and the second position; and 
 an articulation member movably coupled to the mounting bracket, the articulation member configured to couple with the rotary broom. 
 
     
     
         13 . The cold planer of  claim 8 , wherein the rotary broom is actuated by a hydraulic system of the cold planer. 
     
     
         14 . The cold planer of  claim 12  comprising a pivot member configured to couple the carriage system with the frame, the pivot member allows movement of the frame in a vertical direction relative to the carriage system during a rumble strip operation on the work surface. 
     
     
         15 . The cold planer of  claim 14 , wherein the coupling arrangement allows the rotary broom to stay in the second position thereof while the frame moves in the vertical direction during the rumble strip operation on the work surface. 
     
     
         16 . The cold planer of  claim 14 , wherein the carriage system comprises:
 a first platform disposed above the rotary broom and configured to couple with the pivot member; and   a second platform connected to the first platform and disposed proximal to the work surface, the second platform configured to carry the operator thereon.   
     
     
         17 . The cold planer of  claim 16  comprising a control module disposed on the first platform and communicated with a control system of the cold planer, wherein the control system is configured to control the operation of the cold planer based on an input from the operator. 
     
     
         18 . The cold planer of  claim 17 , wherein the control module is configured to receive the input from the operator to control the operation of the cold planer. 
     
     
         19 . A method of controlling an operation of a cold planer, the method comprising:
 moving a set of ground engaging members over a work surface;   moving a rotor over the work surface, wherein the rotor is coupled to a frame of the cold planer and disposed adjacent to the set of ground engaging members;   moving a rotary broom over the work surface, wherein the rotary broom is coupled to the frame and disposed behind the rotor; and   controlling the operation of the cold planer from a carriage system, wherein the carriage system is pivotally coupled to the frame and disposed above the rotary broom.
