The revamped Terex PR950B half-/full-lane milling machine features a new engine that operates at a lower-engine rpm to substantially reduce noise levels and improve operator comfort. Its new service center and work platform offers unobstructed access to the engine, filters and hydraulic pumps, while its new service panel offers quick troubleshooting of the hydraulic system in the field. The PR950 offers a standard 86-inch cutting width with 103-, 135- and 150-inch widths available. A tapered housing design carries substantially less material, improving production and reducing cleanup.

The Volvo MT2000 is a four-track, front-load, half-lane milling machine powered by a 610-horsepower, Tier 3-certified Cummins engine. The machine offers three distinct engine- and drum-cutting speeds selectable from the operator’s panel, an industry first, according to Volvo. The MT2000 can run both 78.74-inch (2,000-mm) and 86.02-inch (2,185-mm) wide drums.

The new Dynapac PL500T is a 20-inch compact cold planer that offers a maximum cutting depth of 6.3 inches. Available as three- or four-wheeled units, the PL500T is powered by a Cummins QSB 4.5 C110/C130 diesel engine with a rating of 110 hp at 2,200 rpm. The cold planer features a hydraulically-operated front sealing of the cutter housing to minimize the accumulation of the milled material. 

Caterpillar’s PM200 Cold Planer with an optional 88-inch (2.2-meter) cutting rotor is a high-production, highly-maneuverable half-lane milling machine that performs controlled full-depth removal of asphalt and concrete pavements in a single pass. Now, two cutting-width options when purchasing the PM200: the standard 79-inch rotor or the new 88-inch rotor option. Operating weight for the PM200 is about 66,359 pounds with the standard 79-inch rotor package; the weight increases to 69,445 pounds with the optional 88-inch rotor package. Both rotors feature conical tool holders and have a maximum cutting depth of 12.6 inches. The 79-inch conical tool holder rotor is equipped with 178 carbide-tipped tools, and the optional 88-inch conical tool holder rotor is equipped with 193 carbide-tipped tools.

Roadtec’s RX-400 cold planer features a 48-inch standard cutting width, and an optional variable cutting system including 26- and 36-inch widths and a 60-inch cutting-width package. Maximum cut depth is 12.5 inches. The cold planer has a 325-horsepower Caterpillar C9 ACERT engine and has been redesigned recently to include a bolt-on design for the right rear leg with a swivel pivot point for steering. All key sizes on the machine’s leg tubes are now the same, and the RX-400 and the RX-500 both use a common key design now. The hydraulic system has undergone modifications to prevent excessive leakage at low speed under load. Its maximum operating speed is 172 feet per minute.
