Abstract
A stump grinding system that includes a vehicle and a stump grinder adapted to engage with the vehicle. The vehicle has a first end, a second end opposite to the first end, and a longitudinal axis defined therebetween. The stump grinder includes a chassis operably engaged with the vehicle at one of the first end and the second end. The stump grinder also includes a body operably engaged with the chassis and a grinder wheel operably engaged with the body and partially disposed outside of the body from the vehicle. The stump grinder also includes a drive assembly operably engaged with the grinder wheel and the body. The grinder wheel of the stump grinder is configured to rotate in a plane that is orthogonal to the longitudinal axis of the vehicle.
Claims19
A stump grinding system, comprising:
- a vehicle having a first end, a second end opposite to the first end, and a longitudinal axis defined therebetween;
- and
- a stump grinder adapted to engage with the vehicle, the stump grinder comprises:
- a chassis operably engaged with the vehicle at the first end or the second end;
- a body operably engaged with the chassis;
- a grinder wheel operably engaged with the body and partially disposed outside of the body;
- and
- a drive assembly operably engaged with the grinder wheel and the body, the drive assembly comprises:
- a power takeoff (PTO) assembly operably engaged with a PTO of the vehicle, wherein the PTO assembly comprises:
- a PTO pulley;
- a PTO drive shaft operably engaged with the PTO pulley;
- and
- a PTO belt operably engaged with the PTO pulley and the PTO of the vehicle;
- a belt drive assembly operably engaged with the PTO drive shaft;
- and
- a grinder drive shaft operably engaged with the belt drive assembly and the grinder wheel, the grinder drive shaft having a first end, a second end opposite to the first end, and a longitudinal axis defined therebetween that is parallel with the longitudinal axis of the vehicle;
- wherein the grinder wheel is configured to rotate in a plane that is orthogonal to the longitudinal axis of the vehicle.
A stump grinding system, comprising:
- a vehicle having a first end, a second end opposite to the first end, and a longitudinal axis defined therebetween;
- and
- a stump grinder adapted to engage with the vehicle, the stump grinder comprises:
- a chassis operably engaged with the vehicle at the first end or the second end;
- a body operably engaged with the chassis;
- a front end positioned proximate to the body;
- a rear end positioned proximate to the chassis and opposite to the front end;
- a grinder wheel operably engaged with the body and partially disposed outside of the body;
- and
- a drive assembly operably engaged with the grinder wheel and the body;
- and
- a push blade assembly operatively engaged with the body;
- wherein the grinder wheel is configured to rotate in a plane that is orthogonal to the longitudinal axis of the vehicle;
- and
- wherein the push blade assembly is independently rotatable on one or both of the chassis and the body along a longitudinal axis of the stump grinder defined between the front end of the stump grinder and the rear end of the stump grinder.
A method of cutting a stump from a ground surface, comprising steps of:
- engaging a stump grinder with a vehicle;
- introducing a grinder wheel of the stump grinder to the stump;
- initiating rotation of the grinder wheel via a drive assembly of the stump grinder, wherein the grinder wheel rotates in a plane that is orthogonal to a longitudinal axis defined by the vehicle;
- cutting the stump from the ground surface;
- and
- rotating a push blade of a push blade assembly, via an actuator of the push blade assembly, between a front end of the stump grinder and a rear end of the stump grinder.

- rotating a power takeoff (PTO) drive shaft of a PTO assembly of the drive assembly, via a power takeoff of the vehicle, along a first drive axis defined by the PTO drive shaft;
- and
- rotating a grinder drive shaft operably engaged with the grinder wheel, via a belt drive assembly of the drive assembly, along a second drive axis defined by the grinder drive shaft,
- cutting the stump from the ground surface;
- and
- engaging cut stump material, via a push blade assembly, on the ground surface.
