Grind Stumps up to 11 Inches Below Grade Without Belts, Chains, or Clutch Maintenance. Built in the USA by Stinger Attachments, the SG Direct-Drive Stump Grinder couples a high-torque radial piston hydraulic motor directly to a heavy-duty carbide-toothed cutting wheel—delivering maintenance-free stump removal on both Standard-Flow and High-Flow skid steers.

The Problem Solver

Remove pesky stumps without the hassle of belt slippage or chain maintenance. The Stinger SG Series is a direct-drive stump grinder designed to penetrate 11 inches below the surface, effectively erasing root balls to allow for sod or seeding.

The Direct Drive Advantage

Unlike competitors that use complex belt systems (which burn out) or chain drives (which snap), the Stinger SG utilizes a Direct Drive Gear Motor. This simple, rugged design transfers power straight to the 24 carbide teeth for maximum grinding torque and long-term reliability.

⚠️ Setup Requirement: Case Drain

This 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: Do not plug this port. Failure to connect the case drain will damage the motor seals and void the warranty.
