    2. Operation 2.1 Introduction The Eterra Stump Grinders were designed to be a highly effective grinding solution. If maintained properly, it will provide the owner with many years of service with no damage to property or people. If not maintained properly, the Stumper can easily injure people or property and will not last as long as the design allows.

  • Page 8: Theory Of Operation

    The Eterra Stumper is a hydraulically operated grinder that uses your existing controls and hydrau- lics to effectively grind stumps. The Eterra Stump Grinder consists of a direct drive grinder head that is mounted on a forward facing mount. The head is powered by connecting directly into the skid steer hydraulic auxiliary system.

  • Page 9: Hydraulic Connections

    2.6 Deflection Shield The Eterra Stump Grinders are fitted with a rubber deflection shield. These shields are provided to allow escaping material to be deflected downward and to the left side. If you remove the deflectors, a lot more material will be projected to the outside of the stump grinder making it very dangerous.
  • Page 10 Connect hydraulic hoses. • The Eterra Stump Grinders are designed for use with most modern skid steer loaders. It is pro- tected from over stress with a unique pressure bypass valve. When you turn your hydraulics on and off, the stump grinder will become a pump and try to put pressure back into the lines. Our valve allows the pressure to re-circulate back into the motor and the wheel to spin down slowly.
