Interesting - the important part of the apparatus appears to
be the roller - if the roller design and weight are correct, I
suppose it can be pulled by any means and operate in
the same basic way. So, if draft animals or people can
move it with a reasonable amount of effort, a tractor
would not be required.
Compaction of the soil using heavy machinery is
a concern, of course, but I think there are many
factors which can effect this. Whether the soil
is bare, or with covering of vegetation, whether
it is wet or dry when equipment is used, the
presence of clay, sand, etc., and (maybe the most
important) the amount of organic material
Running heavy equipment over wet soil with
a lot of clay and little organic material would
probably result in something like concrete. What
is shown in the picture might result in minimal
or no compaction.
But a good general rule would seem to be to use
no bigger or more complex equipment than is
actually necessary. Determining what is necessary or
appropriate in a particular situation is the challenging part, I guess.
