Miller, one of the most respected names in commercial application, is proud to offer you the toughest off-road floater chassis available. By using-top-of-the-line components and leading-edge designs, the rock solid Miller Atlas 3654 can handle the most rigorous field conditions. The Atlas is rated for up to 2000 gallon liquid systems, or you can equip it with either a 13' or 14' dry spinner box depending on the Atlas wheelbase option.
Drive Train
The Atlas off-road chassis feature an unbeatable team of drive line components with legendary performance.
- A 365 Cummins QSL 8.9L diesel engine supplies the power with great fuel economy and excellent cold weather starting. The cooling package features a single pass design to optimize air flow and more efficient cooling.
- Smooth, trouble-free transfer of power from an Allison 6-speed automatic “close ratio” transmission with two shift schedules, a simple push-button shift control, and a transmission oil cooler.
- The Atlas puts the power to the ground with a double reduction Axletech axle with outboard planetary hubs and 2-speed axle ratio.
Speeds
You’ll find the perfect speed for every condition and situation. High and low ranges provide an efficient working speeds from 6.1 to 29.7 mph at full throttle.
Sophisticated air braking system
You’ll enjoy excellent stopping power with 4-wheel air brakes. The two frame rails create a huge air reservoir.
Frame & front axle
The Miller Atlas has evolved from a rock solid legacy of high strength off-road chassis building. High strength steel, 4 walled tubular frame rails with tubular and channel cross members are built to handle the load of a 2000 gallon tank filled with 32% liquid nitrogen.
The front axle is an EATON wide-track with a 6" diameter tube and minimum 18,000 lb. load rating, along with twin hydraulic steering cylinders. The wheel bearings are low maintenance Stemco sealed oil-bath bearings.
The Atlas 3654 is auto-steer capable.
Atlas cab and controls
The command center is a center-mounted Deluxe 90 Series cab for exceptional visibility and control. You’ll appreciate the easy access steps and platform with a walkway to the engine area. It features a large door for easy entry and a comfortable high back Air-Ride seat with an ergonomically designed control panel arm rest. Commonly used controls are built into the armrest and float with the seat. An instructional seat is included.
This state-of-the-art cab is pressurized and charcoal filtered with a standard equipment engine & transmission monitor, heat and air conditioning, a tilt/telescoping steering column, AM-FM radio with weather band and CD player, as well as an HID light option. The cab is well cushioned on account of the air-ride suspension with leveling valve.
Multi-tasking from floater to row cropping
Atlas chassis feature year-long utilization and easy conversion.
The Atlas offers the versatility to transform from floater to row crop unit. Removable fenders are part of this conversion package to give you an exceptional row crop site line to the front tires from the Atlas cab. Row crop tires are centered at 90" tread width.
