west central wisconsin | Wef have heavy soils, and have used 2, 3, and 4 inch. Our favorite is the 2 inch heavy spike. They move the least residue, and last the longest. We tend to chisel plow deep, kinda more like ripping, or a cross between the two. If we hold our speed down, the 2 inch spikes leave a fairly level surface, compared to the 4 inch twisted. As with most things, it is different for everyone, here, we have mostly HEL, heavy soils. |
