I don't know why you guys think the Lillistons are heavy. We have two 8 row machines. They seem like a feather compared to the 8 row Buffalos we have.

We did get a Meridian this year and yes the parallel linkage does add a good amount of weight. I think I like it better on our heavy ground.

I think Lillistons are a good tool in a sandier/looser type soil, but they don't all the weeds on heavy ground. It looks like they do when you pass, but wait a few days and your weeds come right back up.  My experience.
