PROBLEM TO BE SOLVED: To solve problems of conventional turf-cutting blades in which cutting resistance on the blade sides in soil increases as the blade tips wear and increase of required power occurs, because the blade width increases as blade approaches the blade base and heat treatment for partial hardening of the blade can not be carried out, because blade width is uneven and as a result, wear of the blade is quick and use of the blade is not economical. SOLUTION: This turf-cutting blade 1 is attached to a rotating shaft 4 and is composed of a base part 2 and blade parts 3 and the blade part 3 is formed of a blade edge 3a, a blade top 3b and a blade back 3c. The blade width of the blade part 3 is formed so as to become nearly same from the blade to 3b to the blade base and a plurality of blade parts 3 are arranged at equal intervals in the outer periphery of the base part 2.
