I agree with the above
in order to have a lot of good power and break force, your going to need a heavy machine to come close to what your backhoe once did for you!
and I don;t know what you mean by LIGHT, under 10k or such, is what many can only legally tow in some states
so, at that weight, your going to be disappointed IMO to your old backhoe!
maybe what you should do is rent a few different sized machines and see what you like, and then go from there, this way you will have real seat time to make a decision, only problem with this might be, they will all be newer machines and well past the 20 k price to find used?/
but as they say,
some times its better spend more and just buy once than buy a few times, trying to find what you want
renting gives you again, real seat time to judge things!
