Please check out my new garden tool innvention on Youtube 'Easyvator
Rotavator Cultivator - YouTube' (http://tinyurl.com/8n8gcnv) It won
three gold medals for consumer invention of the year at the world
invention awards in London. You can also see it on my website at
'Home - easyvator.net' (http://www.easyvator.net)

In the list of benefits you forgot:

- Destroys soil structure.

Not true, there's no such thing as soil structure where farming is
concerned unless you're an ant farmer.

- Munches earthworms

Total BS... there are billions of earth worms per acre yet it's rare
to damage even one while tilling, as soon as they feel those
vibrations when you start the motor they dive way deeper than you can
till... I till all the time yet have never seen even one mangled worm.

- So light it cannot deal with heavy soil, any soil where it works can be
hand dug.

From someone who has never used a shovel.

- No chance of digging into utilities as it cannot dig deeper than 25cm

Only an asshole would locate a garden directly over buried utilities
regardless how deep.

- Free xray when you rotavate your power cord

That's true, one should never use any electric powered garden tools.

- What happens to the motor/gearbox when the blade stops in heavy soil or
on a tree root? Does it burn out? Does it give the operator a free
chiropractic back adjustment?

The electric motor will just hum until it burns out, but normal
brained folks would immediately cut the power. With fossil fuel
powered the motor simply stalls. Not good for the motor to allow to
occur too often with either.

And the Grand Prize for Thick:

On ground level beds it is so short that it must be operated stooped
unless you are a child. And it is claimed to be suitable for people with
bad backs! The demonstrator groans and holds his back using a spade but
smiles and chatters when using this tool. You are disconnected from
reality.

I think that's more of a single hole planting tool than something used
to till an entire garden. However my "rotovator" planter is far
superior:

I love those ads for the Mantis cultivator. Their soil looks like a bag of
corn meal. Mine isn't that fine.

You've obviously never used a tiller.

For breaking up virgin ground you need something like this 7 HP beast,
notice how it's all covered with dust, hasn't been needed in like six
years, takes two strong men to lift this beast into a pick up bed:

Because once ground has been tilled and cleared of rocks this Mantis
is all one needs and it works like a charm, a young girl can carry it
with one hand:

For tilling some serious area you need something that pulverizes a 6'
swarth:
