I want to buy a garden mulcher. I have in mind a big powerful brute of a
thing that I can use without calling for male muscle power to start it by
pulling the start cord or needing help from Him in the His Shed to help move
around the garden.

That means it must operate by electricity (and I do have hugely long power
cords and external power points) and it must have wheels and be tiltable and
moveable a bit like a wheelbarrow.

I want to shred general garden crud for composting or putting in the chook
run for them to turn and poop on and I also need to shred branches up to
perhaps 3 inches across. Of course I have no idea whatsoever of what size
motor I need or any of the techie type stuff I should know or think about
before buying.

Him in His Shed will not be helpful in providing any answers as it's not one
of the things HE would want to buy. I won't be using his money so need some
neutral male (or techie female) input.

Any comments on the following ones I'm looking at?:

And if none of these appeal, what should I be asking/thinking about please?
