Arnold 21-1/4 In. Mulching Mower Blade Set

When you mulch your lawn, the clippings are cut into very fine pieces that are returned to the grass. This helps to keep your lawn healthier, as it returns nutrients to the soil. And you won't have to spend your time raking or bagging the clippings. 21-1/4" AYP/FHP/EHP mulching blade. Fits Sears-Craftsman/Roper 42" riders. 5/8" star center hole. Replaces OE# 134149.
