A limb and branch trimming apparatus includes a frame having a support platform and an upstanding mast member; a cutting assembly having a plurality of cutting members, wherein the cutting members are rotatably connected at the mast member; and a power source for powering the cutting members independently from the vehicle's power source. The support platform of the limb and branch trimming apparatus is removably mountable to or near the top front portion of a vehicle. The apparatus is used for vertically cutting limbs, branches, and brush along a walkway, pathway, or trail where a tractor would typically be too large to navigate said pathway or trail.
