That was exactly what I was thinking again today as I was running the tractor over the leaves. However, if the OP is really a newbie, one hates to call them a troll or ignore their post. So I went along to surface more info and the context behind of the original question. In the process, we are also surfacing a lot of good info about the OP's topic. One just has to ignore some of the more personal type comments, which is sometimes SOP for a forum. Lots of smart folks with unique personalities in this hobby. Patience with each other's different perspectives goes a long way. Apparent quick judgements go nowhere. To bad our politicians can't figure that out.
