Verifying High-Flow Compatibility on a Bradco Ground Shark Brush Cutter

[MikePhua]

Bradco’s Ground Shark and Its Role in Land Management
The Bradco Ground Shark is a heavy-duty brush cutter attachment designed for skid steer loaders. Manufactured by Paladin Attachments, the Ground Shark series is engineered for land clearing, vegetation control, and site preparation. It’s particularly effective in cutting thick brush, saplings, and small trees up to 7 inches in diameter, depending on the model.
The BC72GS variant refers to a 72-inch cutting width model, commonly paired with mid- to high-horsepower skid steers. These attachments are available in standard-flow and high-flow hydraulic configurations, which directly affect cutting torque, blade speed, and overall performance.
Hydraulic Flow and Hose Configuration
Hydraulic flow rate is a critical factor in determining whether a Ground Shark is operating at full capacity. High-flow models typically require 30–45 gallons per minute (GPM) at pressures exceeding 3,000 psi. Standard-flow units operate in the 15–25 GPM range.
Traditionally, high-flow Ground Sharks are equipped with three hydraulic hoses:

• Pressure line
  
• Return line
  
• Case drain line (also called a third line or leakage line)
  

The case drain line relieves excess pressure from the motor housing and prevents seal damage. However, newer models may use redesigned motors that integrate internal pressure relief, eliminating the need for a separate case drain. This evolution has led to confusion among buyers and operators who associate three hoses with high-flow capability.
Confirming High-Flow Compatibility Without a Third Hose
If a Ground Shark has only two hoses, it may still be a high-flow model—provided the motor is designed to handle high-pressure return internally. Manufacturers have begun using advanced gerotor or piston motors with built-in case drain functionality, simplifying installation and reducing hose clutter.
To confirm high-flow compatibility:

• Check the motor’s part number and specifications stamped on the housing
  
• Review the serial plate on the attachment for flow rating and pressure limits
  
• Contact the dealer or manufacturer for a written confirmation of hydraulic specs
  
• Compare with identical units on the lot that have three hoses—differences may be internal, not visible
  

If the unit was sold as high-flow and lacks a case drain, request documentation from the dealer confirming the motor’s design. This protects the buyer in case of future warranty claims or performance issues.
Anecdote from the Blue Ridge Foothills
A landowner in Georgia purchased a Kubota SVL95-2 and paired it with a Bradco Ground Shark for clearing his property. The attachment had only two hoses, raising concerns about whether it was truly high-flow. The dealer assured him that the motor had been upgraded and no longer required a case drain. To verify, he contacted Paladin directly and received confirmation that the BC72GS he owned was indeed rated for high-flow operation. He now uses it to clear invasive privet and small hardwoods with no overheating or hydraulic issues.
Operational Tips and Safety Considerations
When running a Ground Shark on a high-flow skid steer:

• Always warm up hydraulic fluid before engaging the cutter
  
• Avoid sudden directional changes while the blades are spinning
  
• Monitor motor temperature and listen for cavitation or whining
  
• Clean debris from the deck and motor housing after each use
  
• Use protective guards and shields to prevent flying debris
  

If the unit lacks a case drain, ensure the skid steer’s return line is unrestricted and properly routed to avoid backpressure. Excessive return pressure can damage seals even in motors designed for two-line operation.
Recommendations for Buyers and Operators
Before purchasing or operating a Ground Shark:

• Verify hydraulic compatibility with your skid steer’s flow rating
  
• Request motor specifications and flow requirements in writing
  
• Inspect hose routing and fittings for wear or leaks
  
• Confirm warranty coverage and service support from the dealer
  
• Keep a log of operating hours and maintenance actions
  

For those new to land clearing, start with lighter brush and gradually increase workload. The Ground Shark is a powerful tool, but its effectiveness depends on proper hydraulic matching and operator awareness.
Conclusion
The Bradco Ground Shark remains one of the most capable brush cutter attachments in the industry. While hose count has traditionally indicated flow class, newer motor designs challenge that assumption. Buyers must rely on documentation, serial data, and manufacturer support to confirm high-flow compatibility. With proper setup and verification, the Ground Shark can transform overgrown land into manageable terrain—whether it runs on two hoses or three.
