10,031-pound operating weight
57-hp engine

Terex/CMI PR600 Cold Planers
With a 600-hp diesel engine and operating weights approaching 91,200 pounds, the three- and four-track Terex/CMI PR600 cold planers from Terex Roadbuilding are designed for high-production milling and rehabilitation of asphalt surfaces.

Center-mounted cutter design
10-degree tapered front and rear moldboard design
48-inch-diameter cutter with 177 tungsten carbide teeth

Wirtgen WR 2000
The WR 2000 midsized stabilizer/reclaimer cuts grades or asphalt roadways up to 20 inches deep at a 79-inch cutting width.

400-hp engine
Operating weight of 48,060 pounds
Stabilizes with both emulsion and foamed asphalt; can be equipped with a high capacity water pump for dry soil conditions and cement or lime stabilization projects

Caterpillar PM-200
Caterpillar's PM-200 features a 575-hp Cat C18 engine with ACERT technology.

79-inch rotor width
12.5-inch rotor depth
68,122-pound operating weight
Load Sensing Propel System

Caterpillar PM-201
Caterpillar's PM-201 features a 650-hp Cat C18 engine with ACERT technology.

83-inch rotor width
12-inch rotor depth
41,310-pound operating weight
Load Sensing Propel System

Dynapac PL2000 S
The PL2000 S cold planer from Dynapac features an 80-inch cutting width.

Water spraying system keeps the drum cool, reduces dust levels and cleans the bits
Four control panels on the left and right sides make it possible to monitor and control the planing operation from ground level as well as from the operator's platform
Electronic feedback control system controls the cutting depth allowing unit to compensate for uneven areas of ground and to comply with preset nominal values

Bomag Recycler/Stabilizers
The rear-wheel-drive MPH362-2 and four-wheel-drive MPH364-2 recycler/stabilizers now offer an electronically controlled, 360-hp Cummins QSM11 six-cylinder, water-cooled Tier III diesel engine.

Double-reduction planetary rear drive system propelled by a pair of axial piston, variable-displacement motors
Automatic Power Adjustment System
Both models available in three rotor configurations with cutting depths from 12 to 21 inches

Terex/CMI RS350 Reclaimer/Stabilizer
The Terex/CMI RS350 reclaimer/stabilizer from Terex Roadbuilding uses a single drum for both reclamation and soil stabilization projects.

Does not require permits for transport
Standard, four-wheel hydrostatic drive
Rear-mounted rotor design
Two cutter speeds, 100 and 150 rpm
350-hp Cummins turbocharged diesel engine

Caterpillar RM-300 Rotary Mixer
The RM-300 is capable of both full depth reclamation and soil stabilization.

Cat C11 engine with ACERT Technology
Optional features include a sliding operator's station, pressurized cab, automatic depth control, four mode steering, rear wheel-assist and two redesigned rotors with increased cutting depth capacity
Rear wheel-assist allows the rear wheels to be driven by a separate hydraulic pump to provide increased tractive effort

Caterpillar RM-500
The new RM-500 provides high productivity in both asphalt reclamation and soil stabilization applications where the mixing depth does not exceed 20 inches.
