Com: joan smith : I wonder if all the dust and dirt your throwing up in the air with your machine suggests that your killing the biology in the soil and promoting erosion and dead dirt..

Com: Yanmar tractor : I like the design of this Dondi,

but I have to wonder why all the legs are set at the same depth.

If it were mine I'd chop the front legs 4" shorter and drop the whole thing in deeper so you first break 1-12" then 12-20".

Good video though, and nice colour tractor!

Com: tractors : the subsoiling work is an excellent preparation for the soil,

decompresses the soil increases the oxygenation of the soil,

better water absorption and greater area for root growth plus lower productivity erosion index.
