The 480B tracked mulcher and 4061 mulching head are new offerings in Tigercat’s industrial product line.
The new high production mulcher is designed for difficult terrain work in primarily right-of-way and site preparation projects. The 480B has a power rating of 411 kW (550 hp) at 1,800 rpm. It uses a Tigercat FPT C13 Tier 4f engine with quick load response and good fuel economy. The Tigercat FPT engines are backed by Tigercat warranty and support. A closed loop track drive system provides high tractive effort and performance with good hydraulic efficiency in challenging terrain. The high-lift boom geometry makes the mulcher more productive in slopes and gullies. The cab interior is quiet and instrumentation has been placed to optimise productivity. The electronic control system interface uses a high-resolution, 7-inch touch screen. The 480B is equipped with a heated and cooled seat with air-ride suspension. Good cab insulation ensures reduced noise levels so operators can take full advantage of a Bluetooth® sound system with hands-free calling.
The new 4061 mulching head has been designed for high durability and reliability. It is best suited to be used with the Tigercat 480 and M726 series mulchers. The mulching head housing features reinforced side covers and abrasion resistant skis. The housing is optimised with debris door cylinders mounted internally for protection and contains position references to aid in ski alignment. Timing belts eliminate belt slip and provide efficient power transfer to the rotor, lowering maintenance time and costs associated with conventional v-belts. The Tigercat designed tooth and holder system uses a taper lock interface that requires no torque wrenches, greatly reducing changeover time. The teeth are extremely durable with carbide tips and carbide inserts for increased life. Tigercat indicates that unlike competing mulching heads, the 4061 wear liner requires no welding and the rotor does not need to be removed when servicing. There are also reversible and interchangeable shear bars for quick servicing. In addition, a tapered housing shields debris from potential build-up and easily accessible grease points make daily servicing even more convenient. Source
