BRON’s newest series of Mulcher Models, the 490 and 590, replace the previous generation of 475 and 500. Both new machines are powered by a fuel efficient Cummins QSX15 Tier-IIIi 15-L engine.
The 490 is rated at a 480 hp peak at 1,800 rpm. The 590 is rated at a 589 hp peak at 1,800 rpm. The increased speed rating over the previous models provides additional range for the engine to operate, and results in improved efficiency by using less fuel per horsepower, according to the manufacturer.
Hydraulic power comes from closed-loop pumps for both track drives and mulching head, providing performance and control for high productivity.
Purpose built frames unique between the two models incorporate new oscillating track frames with D4 as standard on the 490, with optional D5; the 590 comes standard with D5 tracks. These tracks are powered by heavy-duty planetary drives that are matched to the size of the selected undercarriage.
Two specially designed extreme service heat exchangers are designed for improved cooling in even the hottest climates. Optimally positioned to draw cool/clean air in from the rear of the tractor, then directed alongside the engine, maximizing air-flow efficiency, reducing wasted horsepower and excessive noise. The open area between the heat exchangers also provides ample room for service to the front of the engine.
