If you want and need the very best in tillers on the planet, pony up and buy a BCS you will not regret it. A person has to see one and work one in person to appreciate this level of quality machinery. It's like a walk behind tractor in a way. With all the bells and even a whistle.
I had a 12 hp. BCS 852 and wish I never sold it, (don't have any sunlight for a garden and the animals will eat what I plant anyway). Yes, they have smaller versions but the man tillers are around 10 hp and up.
If you are serious about tilling, this is what the professionals use. To get an idea regarding attachments, one attachment is a seat on wheels so the tiller can "drive" you back and forth to your destination! It's for 4th gear use, 4th will make you run without the seat even just above idle.
There are an abundance of attachments including wheel weights, snow thrower, mower, sickle bar, roller broom, and a chipper/shredder. It will own any soil.
Made in Italy, the BCS line up is not for your average home owner, it's for farmers. Pick up a catalog and be ready to drool !
