Question:
Can I use a self-propelled deck 3 in 1 blade for the 7021P lawn mower? The blade is labelled "21'' Premium Self-Propelled Deck 3 in 1 Blade" and the model numbers listed are 7021CH1/M among others, but not 7021P. 7021P is a push lawn mower; the blade looks not much different from the blade originally in the mower.
What is the correct (mulching) blade to use for 7021P, and are there any online retailers that can be relied on to ship the right version?
Thank for helping!!
