Simplified RX-405 Controls
Operators run the controls from either side of the platform. Astec arranged the joystick functions and onboard diagnostics so new operators learn them fast.

Roadtec RX-405 Cold Planer
The Roadtec RX-405 is the compact cold planer in the Roadtec lineup. It works in tight spots: utility trenches, parking lots, and urban repairs. The machine keeps commercial milling controls, VCS drum flexibility, and ACE grade control. Power comes from a 430 hp Cummins L9.

Overview
Built for utility cuts, parking lots, trenches, city repair work, and tight milling jobs.
The RX-405 gives contractors a smaller cold planer with full commercial tooling. Astec sized it for restrictive job sites. On those sites, maneuverability, drum changes, and finish control count for more than full-lane production.
Astec builds the RX-405 for trenches, utility work, parking lots, and other space-limited milling. Closner adds Texas field support, parts, and tooling guidance. We also help crews decide between the RX-405 and a larger RX-600 or RX-700.
The Variable Cutter System is the main advantage. Crews change the drum in one cutter housing to cut 24 in, 36 in, 48 in, or 60 in widths. No second housing has to sit in the yard.
Features
What makes the RX-405 work
Easy Cutter Drum Access
A hinged side door on the cutter housing gives crews practical access for drum service, tooling checks, and drum-width changes.
Variable Cutter System
The RX-405 VCS package supports 24 in, 36 in, 48 in, and 60 in cutter widths without swapping the whole cutter housing.

How to compare it
Choose the RX-405 when job access and width flexibility matter more than high-volume truck loading.
Step up to the RX-600 when you need a 675 hp machine with wider standard cutter housings and more city-street production.
Step up to RX-700 or RX-900 for highway, deep-cut, half-lane, and full-lane milling.
Closner support
Texas milling support beyond the machine sale
Closner helps milling contractors think through cutter drums, teeth, track configuration, truck flow, transport, parts stocking, and service planning. The machine page gets you to the right model; the local support keeps the job moving.
