Hi Rob, yes, mate, the bottom blade is attached to its "bed" which is its holder....on the Scott Bonnar it is fabricated in
cast iron hence my caution in using a impact wrench or rattle gun or (heaven forbid) a hammer any where near it. Being dissimiliar metals, the screws have a habit, especially with moisture all around, to almost weld themselves in place....making removal very difficult, unless you know what you are doing. A mate of mine cracked his, and they are many $$$ to replace.
My bottom blade holder (bed) is attached by 4 bolts and very easy to remove.....As for your Alroh, I don't know the set up, but should be relatively easy to remove.
Please let us know how you get on.
