Heavy duty Earth Auger?

Did anyone used this Earth auger in their own farm yards or anywhere? I was lloking it and fery simple to anyone who can afford to buy and planting for plants,
Yeah I tried hitting that clay with the shovels. I gave up. After being able to flip my whole backyard in michigan with a shovel.
I used similar once, but it was manual and then tested the diesel Earth auger which works perfectly. If you are not satisfied with the current design, then make one yourself.
