Can I install cellulose insulation without a blower machine?
Having just done this, I'll report: doable, but a huge PITA. In order to get a good "fluff" on it, I ground it through expanded metal mesh (having tried a few other things which did not work as well first) - it's time consuming and dusty, but certainly possible if all you have to do is a bag/block or two. I've done one block, I might do another just to check the quality of a different supplier before placing a large order.

In my case it was a deliberate experiment, and the result of the experiment is that I will rent a blower ($70/day at the local rental place) and blow in (actually, I'll check against the cost of "having it done," as well); also that I won't be buying HD's "cellulose", which had a significant amount of plastic scrap in it (one does get up close and personal with the insulation when hand-grinding it through a sheet of expanded metal mesh.) 

Methodology was to pry out a chunk of compressed insulation, place it on the expanded metal (an old patio table, in this case) and use a block (or your hand, but the block is more efficient and does not mind grinding on metal) to work the insulation though the mesh - then shovel/sweep to where it's needed (open attic application, not wall-stuffing.) A better setup could be made by building a box with sides and a mesh bottom to work it through, but it's not enough better to beat just using the right equipment on a larger-scale job. Certainly possible to do, however, if you have the time and patience and a dust mask - when what needs doing is small, and the rental of a machine exceeds the cost of the insulation.
