1. 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.

12. 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.

13. 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.

19. 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;
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.
