Never allow children to operate or ride on the Tractor or Implement. (SGM-11) WARNING! Do not mount the Tractor while the tractor is moving. Mount the Tractor only when the Tractor and all moving parts are completely stopped. (SG-12) DANGER! Start tractor only when properly seated in the Tractor seat.
SAFETY WARNING! Transport only at safe speeds. Serious accidents and injuries can result from operating this equipment at unsafe speeds. Understand the Tractor and Implement and how it handles before transporting on streets and highways. Make sure the Tractor steering and brakes are in good condition and operate properly. Before transporting the Tractor and Implement, determine the safe transport speeds for you and the equipment. Make sure you abide by the following rules: 1.
SAFETY DANGER! KEEP AWAY FROM ROTATING ELEMENTS to prevent entanglement and possible serious injury or death. (SG-24) DANGER! Never allow children to play on or around Tractor or Implement. Children can slip or fall off the Equipment and be injured or killed. Children can cause the Implement to shift or fall crushing themselves or others. (SG-25) DANGER! NEVER use drugs or alcohol immediately before or while operating the Tractor and Implement.
SAFETY WARNING! Extreme care should be taken when operating near loose objects such as gravel, rocks, wire, and other debris. Inspect the area before mowing. Foreign objects should be removed from the site to prevent machine damage and/or bodily injury or even death. Any objects that cannot be removed must be clearly marked and carefully avoided by the operator. Stop mowing immediately if blades strike a foreign object.
SAFETY WARNING! Never Leave the mower unattended while the head is in the raised position. The mower could fall causing serious injury to anyone who might inadvertently be under the mower. (SBM-4) WARNING! The rotating parts of this machine continue to rotate even after the Tractor has been turned off. The operator should remain in his seat for 60 seconds after the brake has been set, the PTO disengaged, the tractor turned off, and all evidence of rotation has ceased. (SBM-5) “Wait a minute...
SAFETY WORK AREA PREPARATION It is the intention of this manual to inform owners and their operators of some of the dangers inherent in the use of this epuipment. The machine is an effective, durable and simple tool and when used correctly will provide satisfactory results with minimal danger. These warnings are intended to help ensure that operators and maintenance personnel treat the machine with the respect and care that a powered, edged tool demands and enjoy trouble-free and safe usage.
SAFETY 3. An area to be cut must first be inspected for objects that could be thrown or that could damage the machine. Walk through the area looking for overgrown fences, boulders and rocks, culverts, stumps or metal objects. Mark the inspected area with flags. If the area is dense and cannot be walked thoroughly it may be necessary to inspect a smaller area as well as possible, then trim away the part that has been inspected and can safely be removed.
SAFETY Reversing the direction of rotation of the cutting head on side opening machines increases the chances of objects being thrown out because of the position of the "gate" in relation to the boom arm. When clearing brush and small trees, start at the top and then lower the head down through the brush while sweeping from right to left. This avoids clogging the head with mulched material.
SAFETY ATTENTION! This unit was shipped with an Operator’s Manual Specifically designed to remain with the unit at all times. This manual is to be stored in the protective canister shipped with this unit. Because it is not feasible to attach the protective canister to the unit directly due to severe conditions in which it operates, the canister must be installed in a secure area such as the operator’s station.

INTRODUCTION SECTION Introduction Section 2-1
INTRODUCTION The Grizzly is a dependable machine designed specifically for removal of brush, scrub, shrubbery, small trees and other undergrowth in rural areas. This machine is not recommended for use in populated and built-up areas. The Grizzly utilizes hydraulically driven rotating steel blades, rotating disc with cutter bits, or a rotating arbor with flail hammers.
INTRODUCTION GENERAL INSTRUCTIONS The Grizzly has been designed to help alleviate the environmental problems associated with the increased use of chemical defoliants. 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 is both efficient and environmentally acceptable. The Grizzly is so efficient that the operator can pass from dense brush cutting to grass cutting with the same machine.
ASSEMBLY SECTION Assembly Section 3-1
ASSEMBLY PRE-INSTALLATION Prior to installing the Girzzly on the carrier, check to make sure that the combination of carrier and Grizzly is correct and is as ordered. INSTALLATION The cutter requires a constant flow of hydraulic oil and must be provided with a supply that will not be reduced when another function of the machine is used simultaneously.

OPERATION SECTION Operation Section 4-1
OPERATION IMPORTANT: Read this section carefully and follow the instructions outlined before starting up the machine. Failure to follow the procedures outlined in this manual may result in personal injury to the operator or bystanders, or in damage to the machine. Pre-Startup Operation of the Grizzly must be restricted to operators who have read and completely understand all Safety Rules, Precautions and Operating Functions of both Tractor (carrier) and the Alamo Grizzly.
OPERATION Two Blade Arm, Three Blade Disc & Disc (w/ Cutter Bits) 1) Check the attachment of the Grizzly to the carrier to ensure that all attachment point bolts and pins are in good order. 2) Check all hydraulic lines and connections for leaks and security. 3) Check the fluid level in the hydraulic tank. 4) Make sure the control vavle is in the "OFF" position.
OPERATION NOTE: Preform the following run-up check over grass if possible to avoid raising dust. 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 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.
MAINTENANCE SECTION Maintenance Section 5-1
MAINTENANCE General Maintenance The importance of regular maintenance and inspection as a means of prolonging the life and maintaining the efficiency of the Grizzly cannot be overemphasized. For lubrication use Shell EP2 grease or equal. The bearings are packing during assembly. Each bearings should be given one 'shot' of grease with a hand gun each day (8 hour shift) before starting up. DO NOT OVER GREASE. A hot bearing housing usually indicates overgreasing.
MAINTENANCE - Using a large pair of snap ring pliers, remove retaining ring from the bottom of the housing. - Remove bottom cover from housing. - Wash all parts in solvent and inspect carefully for damage or excessive wear. Magnaflux the shaft while disassembled. - When ordering replacement parts, refer to Parts Section for correct part numbers and ensure that all parts are genuine Alamo parts. DO NOT use substitutes.
MAINTENANCE - Remove shaft complete with upper bearing from bearing housing. Remove bearing from shaft. - Using a large pair of snap ring pliers, remove retaining ring from housing. - Remove lower cover and lower bearing from housing. - Wash all parts in solvent and inspect carefully for damage or excessive wear. Magnaflux the shaft while disassembled. - As a general rule, always use new oil seals and lockwashers when re-assembling.
MAINTENANCE BIKON TORQUE VALUES (TABLE 1) Dry Bolt w/ Red Locktite Appplied 375 ft/lb 282 ft/lb FIGURE 1 BIKON TORQUING SEQUENCE PROPER TORQUE FOR FASTENERS The chart lists the correct tightening torque for fasteners. When bolts are to be tightened or replaced, refer to this chart to determine the grade of bolts and the proper torque except when specific torque values are assigned in manual text.
MAINTENANCE Motor Mounting Plate NOTE: The Motor Mounting Plate must be true to shaft to prevent excessive wear on couplings and splined inserts. 1. The surface of the shroud and motor mount plate must be flat with no rocking allowed. 2. Clamp and dial in Motor Mounting Plate to Grizzly Housing Shaft. 3. Drill 4 holes for mounting bolts. 4. Bolt Motor Mounting Plate to shroud and check run out. Adjust position of plate to meet tolerances for maximum indicated run out. See Table 3. 5.
MAINTENANCE The frictional torque capacity of these devices is based on lightly oiled screw, taper, or shaft and bore contact areas with a coefficient of friction µ = 0.12. Therefore, it is important not to use Molybdenum Disulfide, e.g., Molykote, Never-Seeze or similar lubricants in any locking assembly installation. 1. Make sure shaft and bore contact areas are clean and lightly oiled. 2.
MAINTENANCE (TABLE 4) Removal 1. Make sure axial movement of clamp collars - necessary for release of connection - is not resricted. 2. Relax all locking screws by at least 2 turns and transfer locking screws into all push-off threads provided in clamp collar item "1" and center collar item "3" as illustrated in Figure 2. 3.
