A vegetation cutting tool (100) includes a cutting head (10), an input shaft (45), an output shaft (46), a transmission assembly (44) and a transmission housing accommodating the transmission assembly. The transmission housing (40) includes a skirt portion (41) having a small end away from the cutting head and a big end adjacent to the cutting head, a shank (42) extending along the first axis from the skirt portion, and a stop portion (43) connecting the skirt portion and the shank. The stop portion forms a stop face extending from the skirt portion to the shank for preventing grass clippings winding around the transmission housing.
