PROBLEM TO BE SOLVED: To provide a pruning machine which prevents deterioration in cutting performance of cutting blades.SOLUTION: A pruning machine includes a pair of upper and lower blades 51 and 61, where a plurality of cutting blades 53 and 63 are provided in a row on the sides of long parts 52 and 62, cutting a plant by reciprocating while keeping themselves in a sliding-contact state. Rake faces 53b and 63b are formed on cutting edge parts 53a and 63a of the cutting blades 53 and 63 so that a component force generated by cutting resistance occurring when cutting, which forces the cutting blades 53 and 63 to press each other, is smaller on the side of a blade end compared to on the side of a blade base. |
