Page 68 This machine is not recommended for use in populated and built-up areas. The Grizzly 66 utilizes hydraulically driven rotating steel blades, rotating disc with cutter bits, or a rotating arbor with flail hammers. It is usually mounted on the hydraulic boom arm of a tractor, excavator or similar carrier, and employs the hydraulics system of the carrier for operation of the hydraulic drive motor.
Page 69 Suited for clearing roadway or off-highway right-of-way, clearing of power line underbrush, pipeline right-of-way and forestry thinning in dense growth, the Grizzly 66 is both efficient and environmentally acceptable. The Grizzly 66 is so efficient that the operator can pass from dense brush cutting to grass cutting with the same machine.

Once the direction of rotation has been determined to be correct and the Control Valve notation indicates the correct direction (in the case of dual direction installations), return the Grizzly 66 to the horizontal position a foot or so above the ground and run it up to speed. It will probably be necessary to increase the engine speed to provide adequate hydraulic pressure/volume to reach maximum shaft speed.
Page 97 Tire damage can occur when driving over hot material. Oil and grease on the carrier and cutter could ignite resulting in equipment destruction. Carry a fire extinguisher on the power unit at all times to extinguish possible fires encountered. GRIZZLY 66 03/08 Operation Section 4-21 © 2008 Alamo Group Inc.
