Naw just move it in and out. I use lump so there's not a whole lot of ash but it does shake it down into the pan. Hell I guess I have to much free time on my hands at work. Beats shakin the whole smoker.
I use lump also. I have double grates (added the grate from an 18-1/2 kettle) on the bottom so the small lump pieces don't fall thru. It may work with both?
