The utility model discloses a low seam coal cutter comprising a coal cutter body, a first rocker and a second rocker, wherein the first rocker and the second rocker are arranged at two ends of the coal cutter body; the coal cutter body comprises an electric cabinet, a first traction section and a second traction section; the first traction section and the second traction are arranged at two sides of the electric cabinet; traction motors are transversely arranged on the first traction section and the second traction section and connected with a traction drive system; the traction motors of the first traction section and the second traction section are arranged above a side channel on a coal wall of a conveyer and a ramp plate; the traction drive system is arranged above the side channel on the coal wall of the conveyer and the ramp plate; cutting motors are transversely arranged on the first rocker and the second rocker and connected with a cutting drive system. By adopting the low seam coal cutter, the contradiction among the height of the low seam coal cutter, a coal space and power of the cutting motors in a conventional arrangement mode is solved, and meanwhile, the gravity center of the coal cutter is still at the inner side of a support skid shoe. Therefore, the low seam coal cutter has the good stability and adaptability.
