  • Page 16: Installation Instructions

    INSTALLATION INSTRUCTIONS GENERAL INFORMATION The following instructions will help you to mount your brush cutter onto your skid steer loader. The brush cutter uses the quick-attach system for ease of installation. Therefore, if you know how to attach your loader bucket, attaching the brush cutter should prove no problem. Remember to read all safety warnings, decals and operating instructions before operat- ing the attachment.

  • Page 17: Operating Instructions

    OPERATING INSTRUCTIONS INTENDED USE: The Ground Shark brush cutter is designed for cutting brush and small trees up to 7” (178mm) in diameter while still maintaining a 12” (305mm) maximum ground clearance. When equipped with the tooth kit, the attachment will also grind the remaining stumps down to ground level.

  • Page 18: Cutting Operation

    OPERATING INSTRUCTIONS WARNING! Before leaving the operator's seat: Lower the lift arms against frame and place both skid shoes on the ground. Disengage auxiliary hydraulics. Stop Engine. Engage parking brake. Remove the key. DANGER! ROTATING BLADE HAZARD! STAY BACK! OBJECTS CAN BE THROWN! DO NOT operate near bystanders.
  • Page 19 OPERATING INSTRUCTIONS When cutting large brush and small trees: Roll the front of the brush cutter up 1-2 feet (305-610mm). DO NOT LIFT THE BACK OF THE CUTTER! Slowly drive into the tree. The front shield will raise up allowing the push bar on the brush cutter to push against the tree.

  • Page 20: Troubleshooting Operating Conditions

    OPERATING INSTRUCTIONS TROUBLESHOOTING OPERATING CONDITIONS: Below are listed a few operating conditions that may cause repeated stalling of your brush cutter, and suggestions on how to correct them. GRASS TOO LONG OR THICK: If cutting heavy vegetation, you may need to slow travel speed or make smaller passes (less than full cut) to prevent overloading and stalling the unit.

  • Page 21: Storage

    OPERATING INSTRUCTIONS STORAGE The following storage procedure will help you to keep your brush cutter in top condition. It will also help you get off to a good start the next time your cutter is needed. We therefore strongly recommend that you take the extra time to follow these procedures whenever your unit will not be used for an extended period of time.

  • Page 22: Tie Down Points

    OPERATING INSTRUCTIONS • Attach lifting accessories to unit at recommended lifting points. • Bring lifting accessories together to a central lifting point. • Lift gradually, maintaining the equilibrium of the unit. WARNING! Use lifting accessories (chains, slings, ropes, shackles and etc.) that are capable of supporting the size and weight of your attachment.

  • Page 23: Lubrication

    LUBRICATION GENERAL INFORMATION Economical and efficient operation of any machine is dependent upon regular and prop- er lubrication of all moving parts with a quality lubricant. Neglect leads to reduced efficiency, wear, breakdown, and needless replacement of parts. WEEKLY The oil level in the drive bearing housing should be checked once a week. Fill as neces- sary with a mild extreme pressure lubricant API-GL-5, No. 80 or 90 weight gear lubricant. GSE SERIES (20-34 GPM) CUTTERS TO CHECK: Remove plug from front of drive PLUG bearing housing. Lubricant should be visible and just covering top bearings. DO NOT OVERFILL. TO ADD: Remove plug from end of front of the drive bearing housing and add lubricant until top bearings are covered. Replace plug. GS SERIES (30-45 GPM) CUTTERS NOTE: Oil level should be approximately 2” (51mm) from the top when measuring down from the plug.

  • Page 24: Maintenance Schedule

    MAINTENANCE GENERAL INFORMATION Regular maintenance is the key to long equipment life and safe operation. Maintenance requirements have been reduced to an absolute minimum. However, it is very important that these maintenance functions be performed as described. WARNING! Avoid serious injury. Lower the brush cutter so both skid shoes are on the ground, set the parking brake, stop the skid steer engine, and remove the key before leaving the operator's seat.

  • Page 25: Replacing Blades

    MAINTENANCE WARNING! Avoid serious injury. Lower the brush cutter so both skid shoes are on the ground, set the parking brake, stop the skid steer engine, and remove the key before leaving the operator's seat. Be sure all rotation has stopped before making any adjustments or repairs.

  • Page 26: Replacing Blades

    MAINTENANCE WARNING! Avoid serious injury. Lower the brush cutter so both skid shoes are on the ground, set the parking brake, stop the skid steer engine, and remove the key before leaving the operator's seat. Be sure all rotation has stopped before making any adjustments or repairs.

  • Page 27: Replacing Hydraulic Motor

    MAINTENANCE NOTE: With one hand under the blade carrier holding the capscrew into the bolt head recess, loosely install one capscrew and then rotate the blade with spacer installed around to align the remaining two holes. Repeat steps #3 and #4 for the remaining three blades. After all four blades have been replaced, torque all hardware on the blades and the blade carrier to specification.

  • Page 28: Replacing Drive Bearing Housing

    MAINTENANCE IMPORTANT: If couplers were not disconnected prior to removing the control valve, oil will drain from the skid steer causing extensive oil loss. Remove the capscrews holding the motor to the drive bearing housing, and remove the motor. Check motor seal for damage and replace if required. NOTE: If motor shaft seal was damaged you will need to drain the existing oil from the drive bearing housing and replace with new before installing the new motor.
  • Page 29 MAINTENANCE Attach the hoist to the blade carrier assembly and remove from the brush cutter and set aside. (NOTE: The blade carrier weighs between approximately 300 lbs (136 kgs) on the 66” to 700 lbs. (318 kgs) on the 78” cutter.) With the blade carrier assembly removed.

  • Page 30: Changing Oil

    MAINTENANCE CHANGING OIL IN DRIVE BEARING HOUSING When changing the oil in the drive bearing housing the unit should be setting firmly on the ground with the hydraulic couplers disconnected. We recommend removing the existing oil with a fluid removal pump. Remove one of the plugs in the drive bearing housing and place the extraction hose into the housing so that it reaches the bottom. Place the output hose into an approved container or drum that will hold the waste oil. Following the instructions for your fluid removal pump, remove all oil from the drive bearing housing. Once the oil has been drained from the housing, remove the pump. GSE Series (20-34 GPM) Cutters: Fill the housing up to the plug with a mild extreme pressure lubricant API-GL-5, No. 80 or 90 weight gear lubricant. GS Series (30-45 GPM) Cutters: Fill the housing with approximately 2.50 quarts (2.4 li- ters) of a mild extreme pressure lubricant API-GL-5, No. 80 or 90 weight gear lubricant. NOTE: Oil level should be approximately 2” (51mm) from the top when measuring down from the plug.
