To provide a mower blade cover that is applicable to a blade with a different diameter.SOLUTION: The blade cover 5 is installed in the tip of a fitting part 4 that is attachable to the handle lever 1 of a mower T. The fitting part 4 is composed of an upper half body 6 in which the blade cover 5 is installed in the tip and of a lower half body 7. A fixture 9 inserted in an installation hole 8 provided in the upper half body 6 is fastened in a fastening part 10 prepared in the lower half body 7 and tightened, with the fitting part 4 thereby attached to the handle lever 1 in a fitted state in the structure. The lower half body 7 is constituted so that a fixing direction to the upper half body 6 is variable. By the variation of the fixing direction of the lower half body 7 to the upper half body 6, the projection degree of the blade cover 5 is structured to be variable to the tip of the handle lever 1 in accordance with a blade 2 of a different diameter, in the mower blade cover.SELECTED DRAWING: Figure 4【課題】異なる径の刈刃にも対応使用可能となる草刈り機用刈刃カバーを提供すること。【解決手段】草刈り機Ｔの把手杆１に取付可能な取付部４の先端部に刈刃カバー部５が設けられ、取付部４は、先端部に刈刃カバー部５が設けられている上側半体６と、下側半体７とから成り、上側半体６に設けた取付孔８に挿通した締付具９を、下側半体７に設けた螺着部10に螺着して締付けることにより把手杆１に取付部４が被嵌状態で取付けられるように構成され、下側半体７は、上側半体６に対する固定向きを変更可能に構成されていて、この下側半体７の上側半体６に対する固定向きの変更により、異なる径の刈刃２に対応させて把手杆１の先端部に対する刈刃カバー部５の突出度を切替え可能に構成されている草刈り機用刈刃カバー。【選択図】図４
