CMI has introduced two new, upgraded mulching machines that feature Tier 4 engines and the company’s new ergonomic operators cab. The two machines are the C300 and the C475.
The C300 Hurricane replaces the C250. Equipped with a 290-hp Cummins engine, the tractor can be outfitted with the 83-inch (2.10-meter) or 89-inch (2.25-meter) mulcher or a stump grinding head.
The C475—an upgraded version of the C450— dominates its class with mulching power, dependability and its High Drive track system. It comes with a 475-hp CAT engine and can be ordered with a mulching head or stump grinder. The C475 is about two inches longer than the C450 and more than 7,000 pounds heavier than the old machine. The mulcher pump has a bigger displacement so that it can use all the power supplied by the engine.
Both machines have a new cab that includes an air suspension seat, better visibility and improved ergonomics. For operator comfort, the cab also includes a Bluetooth radio and cupholders.
For ease of operation, CMI is employing a new display panel that’s functional, reliable, and intuitive. The panel displays diagnostics and machine information and allows the operator to easily adjust machine settings. Other improvements for operators include a new implement valve that’s easy to adjust and a thumbwheel on the mulcher joystick for more control.
In moving to a Tier 4 engine, CMI added a heated-and-cooled DEF tank. With the new engines, operators can adjust the regeneration parameters from the control screen, selecting auto or manual regen.
In announcing the updates, CMI stressed customers can be confident the machines will deliver the same reliability and performance they have come to depend upon. “People in our industry like the same reliability and continuity in the components, and that is what we have done,” said Pierre Letourneau, manager of sales for CMI.
The new models deliver the same benefits the company is known for, including being designed by a team of experienced mulching crawler operators to provide performance, maneuverability and reliability.
