This creation is about a kind of mower cutter set.At least one slotted hole is arranged on the cutter head.At least one clamping part is formed on one side of the slotted hole.In this way,When assembled,The locating tip connected at one end of the blade is inserted into the long slot hole of the cutter head.Then, the locating tip is clamped and positioned with the end of one clamping part of the slotted hole.Thus,Adjust the length of blade protruding out of the outside of the cutterhead according to the activity of cutting weed stem thickness.In addition, when the blade is worn,It is also easy to stretch the blade stored in the inside of the cutter head to the outside of the cutter head.To provide continuous mowing,Instead of replacing a new blade,Accordingly,So as to improve the convenience of blade assembly and removal and save the cost of blade replacement.本創作係有關於一種割草機刀盤組，係主要於刀盤上設有至少一長槽孔，並於該長槽孔一側成型有至少一卡合部，藉此，當組裝時，係使刀片其一端部連接之定位梢穿置於該刀盤之長槽孔中，再使定位梢與該長槽孔之其一卡合部末端卡掣定位，依此，即可依切割雜草莖幹粗細活動調整刀片突伸出刀盤外側長度，另當刀片磨損時，亦可簡便將收納於刀盤內側之刀片拉伸至刀盤外，以提供繼續割草使用，而無須置換新刀片，據此，俾達到提高刀片組拆便利性及節省更換刀片成本等效益。
