Well here in Oregon, a very large grower got in 6 last year, he ran them and claims they do a superb job compared to the sts's which he had 3 of the previous year. (Not sure why he did a 3 for 6 trade... maybe the 12 9610's he's already got
)
In grass seed the JD sts has hardly been proven, Deere doesnt know grass seed exists as a crop thus no research has been done to make them work, a couple guys think they got the sts thing down but they are far and few between, so the wts was welcome around my neck of the woods.
