Description
The Balanced Powerhouse
The Stinger F3 Series is the "sweet spot" in the Twister lineup. It steps up from the standard F2 by utilizing a heavy-duty **3-Blade Carrier**, which provides a smoother finish and faster processing speed in thick brush.
The Radial Piston Advantage
Powered by a **Direct Drive Radial Piston Motor**, the F3 delivers 95% efficiency to slice through **6-inch trees** without stalling. Unlike gear motors, this unit creates instant torque recovery, making it ideal for maintaining right-of-ways, trails, and overgrown pastures.
⚙️ Technical Specifications
Cut Capacity: 6" Diameter Trees

⚠️ Setup Requirement: Case Drain
This Radial Piston motor uses a Case Drain (3rd line) to relieve internal pressure.
To protect the motor seals, this line must be connected to your machine's Case Drain coupler (Direct-to-Tank).
Note: Connecting to a standard return port will damage the seals and void the warranty.
