Cat Introduces the New D1 Shredder


Featuring a high-performance powertrain, closed-loop hydraulics and improved screen, the new Cat D1 shredder is designed to optimize performance when cleaning a mixture of small to medium diameter materials. Designed to match the heavy-duty Cat HM518 mulcher, the D1 mulcher clears a 72 in. (188.2 cm) wide swath with each pass, making it ideal for right-of-way construction and maintenance, site development, tree management and clearance of fire breaks .

The new chipper is powered by the 77.6 kW (104 hp) Cat C3.6 diesel engine that meets US EPA Tier 4 Final/EU Stage V emission standards. An alternate emissions package for the C3.6 is available to meet Tier 3 equivalent standards. The machine’s lower sloped hood line improves visibility to the grinder head, allowing the operator to better assess the site from the cabin. The standard auto-reversing fan purges debris from the radiator and cases, and the hinged grille requires no tools to access the radiator for cleaning.

Isolating machine vibration from the operator to reduce fatigue, the Cat HM518 Shredder controls are mounted on the air suspension seat. Inside the pressurized, heated and air-conditioned cab, an intuitive operator interface includes a 25.4 cm (10-inch) color touchscreen with standard rear-view camera display to help improve all-around visibility around the jobsite. An in-cab drum indicator provides a quick overview of drum speed and direction to help the operator manage ground speed and mulching productivity.

Featuring liner material in high wear areas, the new HM518 mulcher frame provides increased life. Bolt-on wear plates provide long life and are quickly replaced. Offering a drum speed range of 2,150 to 2,450 rpm, the 38 fixed drum tines feature a single-bolt carbide tine retention design for simple replacement. Its closed-loop hydraulic circuit includes a load-sensing hydraulic circuit to prevent damage to the rotor when colliding with an obstacle. The HM518 mulcher has a maximum lift height of 78.7 cm (31 in), a maximum tilt of 36.8 cm (14.5 in) and a maximum angle of 25 degrees to each side.

Standard brooms, shields, windows and rear guard help protect both operator and machine when mulching. With its specially designed tractor platform, the D1 mulcher is balanced and robust to increase efficiency when operating in tough applications. Contractors can choose between conventional (XL) or low ground pressure (LGP) undercarriage design, offering track shoe widths of 40.4 cm (16 in) or 63.5 cm (25 in) respectively ), to increase flexibility and efficiency when working on soft ground. conditions, on slopes and in rough terrain. To increase machine versatility, the new D1 mulcher can be equipped with an optional variable pitch/angle/tilt (VPAT) blade in XL, LGP or mid-size configurations.
