  • What flow and pressure do I need to run a Bull Hog?

    The Bull Hog can be configured for a wide range of flow and pressure to suit any high flow skid steer. The minimum flow requirement for a skid steer mounted Bull Hog is 28 gpm, with a maximum flow of 45 gpm. System pressure should be a minimum of 3,000 psi and maximum of 6,000 psi. For excavator and purpose built tractors we require a data sheet to properly configure the Bull Hog.

  • My head has started to lose power. What should I look for as the cause?

    The mulcher uses the flow and pressure created from the carrier. Common causes that affect the head, if the carrier is producing adequate pressure and flow, are:

    • Loose or defective quick disconnects from the carrier to the head
    • Relief valve in the protection block set below the machines system pressure
    • Belt set too loose that has started to slip

    Contact your local dealer if these suggestions do not resolve your issue.

  • I noticed my Bull Hog has a QR code imprinted on the serial number plate. What is this for?

    The QR (Quick Response) code is a readable barcode that allows users to scan with a common application downloaded to a mobile phone. On the Fecon head, service parts specific to your head can be read and displayed on your mobile phone.

  • How long do the standard double carbide tools last? How can I tell when my carbide tools need to be replaced?

    The standard double carbide tools will last for approximately 300-500 hours. This time will vary in different applications, especially in high horsepower tractors or when the application requires frequent ground engagement. If you notice the carbide is missing, replace the tool immediately. The body of the tool will wear out quickly in this situation and can subject the tool holder to damage.


  • What daily maintenance is recommended for my Bull Hog?

    The only daily maintenance we recommend is to grease the rotor bearings. These require at least 1 pump of grease for every hour you run the machine, and they should be serviced every 4 hours. Generally a customer will do 4 pumps of grease in the morning and run for 4 hours before stopping to grease the rotor bearings again. Inspect the tools for tightness and belts for proper tension daily.

  • What torque do the tool bolts require?

    The standard double carbide tools on an HDT rotor should be torqued to 590 ft/lbs. The FGT tools should be torqued to 500 ft/lbs. When torqueing the bolts, make sure the threads are lubricated with oil.


  • What is the proper belt tension?

    The v- belt in a skid steer mounted Bull Hog should deflect approximately 5/16” with 40 pounds of force. The polychain cog belt in the same Bull Hog should deflect about 1/16” with 40 pounds of force.


  • I need to add protection to my machine for operating a Bull Hog, what protection is recommended?

    Any machine that runs a mulcher is required to have at least a ½” thick Lexan or polycarbonate windshield. We recommend a metal mesh guard in addition to the polycarbonate window.

  • Can I move my Bull Hog to a different carrier? What changes are needed to move my Bull Hog to a different carrier?

    The Bull Hog can be moved easily from one piece of equipment to another with very minor changes.

  • What do I need to know to install a Bull Hog on an excavator?

    if you are ordering a new Bull Hog the mulcher will be configured to match your tractor, but you will need to provide pressures and flow for verification.
