A helical coil assembly, consisting of spaced coil turns mounted on a shaft at right angles to the coil, is rotated by any suitable power source. Any plant growth stalks in the path of this rotating coil enter and are caught in the channel between the spaced coil turns, spun centripetally, clumped together, grasped and pulled by the coil so that the plant growth, whether crops or undesirable weeds, undergrowth, etc. is removed by its roots. The helical coil assembly may also include a cutting blade rotating parallelly and adjacent to the helical coil, for severing the clumped plant stalks held under tension by the coil, thus moving or trimming the plant growth. Multiple coil assemblies, arranged in various groupings, are combined for a wide range of mowing, trimming, harvesting or removing purposes.
