Self-Cleaning Air Intake System

In order to provide constant clean air to the engine and radiator, the 9013F employs a hydraulically powered self-cleaning air intake system with 3,400 square inches (21,635.4 sq cm) of air passages. The self-cleaning air intake system reduces maintenance, provides easy access to the radiator for servicing, and allows for flexible positioning of the grinder.

Command Console with Optional Remote Control

The 9013F command console features master engine controls, gauges, and shutoff. Also included on the command console are electric over hydraulic controls for the clutch, governor, and stacking conveyor. The optional 6-function remote controls engine stop, tub rotation, stacking conveyor, and optional tub cover.

Caterpillar C27 Electronic Diesel Engine with Enclosed Engine Compartment

The 9013F is powered by a 950 HP (708.4 kW) Caterpillar Electronic diesel engine and is backed up by Caterpillar’s superior service and reliability. The 9013F is capable of grinding trees at the rate of 350 cu. yds/hr (267.59 cu. m/hr) with the 950 HP engine. The engine is housed in an enclosed engine compartment to protect the engine from debris while reducing noise levels.

PT-Tech HPTO Oil Cooled Clutch

The 9013F Industrial Tub Grinder is equipped with a self adjusting PT-Tech HPTO oil cooled clutch. This clutch is microprocessor controlled with a built-in torque limiter and brake that provide superior protection for the engine and drive line.

Single Drive Orbit Motor Drives the Tub

Utilizing a heavy-duty 120H drive chain, a continuous chain sprocket around the tub, an 8” (20.32 cm) heavy-duty tub channel, and dual spring adjustable chain tension, the tub is driven by a single orbit motor. Tub speed is controlled by the electronic governor.

56” Rotor

The 9013F industrial tub grinder is equipped with a 56” (142.24 cm) rotor mounted on a 7” (17.78 cm) shaft with 4-7/16” (11.27 cm) greasable bearings. The dynamically balanced rotor uses 28 fixed hammers.

36" Wide Belly Belt

The 36” (91.44 cm) wide impact-resistant belly belt carries the finished product to the stacking conveyor.

36” Wide x 26’ Long Oscillating Top Drive Stacking Conveyor

The 36” (91.44 cm) wide by 26’ (7.92 m) long stacking conveyor allows the operator to load material into a truck or onto an existing pile. Additionally, the stacking conveyor swings 50 degrees from side-to-side. An optional magnetic roller and aluminum chute remove ferrous metal from the finished product.
