ABSTRACT:
A stump remover for cutting and grinding tree stumps and roots comprising a rectangular-shape housing which serves to support and contain the various elements of the stump remover. At the aft end of the housing is mounted a power source, preferably an internal combustion engine, which provides rotational energy to the cutting assembly at the fore end of the housing. The cutting assembly comprises a drive shaft which is mounted within the housing at an angle of approximately 61 degrees relative to the top of the housing. The end of the shaft is provided with four radially extending and equally spaced carbide teeth. Each of the teeth includes a bent portion which forms an angle of approximately 45 degrees with the axis of the drive shaft. For the transmission of rotational energy from the power source to the cutting assembly, preferably a cog V-belt is provided. The aft end of the housing further includes a wheel assembly which is mounted slightly behind the center of gravity of the power source so as to cause the housing to rotate forward bringing the cutting assembly in contact with the ground. To assist a user in overcoming the tendency of the housing to tip or rotate forward and allow the user to control the cutting depth, the aft end of the housing further includes a footrest and a handle bar assembly.
