I like the AB in the GB
Are mulch blades all that different? I just pulled the regular mower blade off, filed the crap out of it until it was kind of sharp (there's 0 need for razor sharp that will be gone after the first cutting), & put it back on. Yep, it wasn't a flawless balance. Yep I could replace the blade cheap when it was too far out of balance.
It's a different shape.
