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.
A portable stump remover for cutting and grinding away a tree stump or limb situated within the ground comprising a rectangular-shape housing having a fore and an aft end and a horizontal top plate, a pair of side plates and a fore end plate, said fore end of said housing including a fixed bottom inclined angled plate extending upwardly from one side plate to the other, cutter means to facilitate the cutting and grinding of such stump or root mounted near the fore end of said housing, power means mounted upon said top plate of said housing near the aft end of said housing to provide the requisite rotational force to said cutter means, and wheel means to support said housing above ground level and facilitate the portable movement of the stump remover, said wheel means being mounted and supporting said housing near the aft end of said housing slightly behind the center of gravity of said power means such that said housing tends to rotate forward upon said wheel means causing said cutter means to contact such root or stump, said power means comprising an internal combustion engine having a horizontal stroke piston, said cutter means comprising a drive shaft supported for rotation within a bearing housing fixed to said inclined angled plate, said drive shaft including at one end a plurality of teeth for cutting and grinding such tree stump or root, and said axis of said drive shaft forming an angle of approximately 19 to 39 degrees with respect to a vertical plane extending fore and aft said housing.
