Thanks a lot Redbug, I appreciate that.
I've seen the sit and it did significantly move me in the direction of the Covington camp. Although I'd actually forgotten about it. On that sit, Donald, thebayorgardner, site manager, made an interesting comment; that the Covington worked better when he removed the cultivators and-- more significantly--the entire fertilizer unit including the shovel and two arms that the shovel is attached to and that distributes the fertilizer. This is important to me as the shovel and tubes do not seem to float and this is disadvantages in my circumstances and ruled out the Covington for me. Simply removing them (and the fert. hopper), which I had forgotten about, thanks for reminding me, makes the Covington more practical in my circumstances now. Earlier in this thread someone said that the seeder/planter component of Covington floated. I have not confirmed this yet, but presuming this to be correct, and a floating seeder/planter is essential in my circumstances, Covington has moved up significantly in my estimation.
[Sorry for the stream of consciousness. I'm just thinking out digitally.]
OK, I thought I'd posted earlier a comment on my looking into "local usage". Apparently I didn't hit submit. Long story short, the only guy I can find who has any knowledge of either has a 4 row Cole. He doesn't like it and doesn't use it. Specifically because of the shoe/foot. Too fidgety and tends to clog things up to much in his estimation. He prefers disks. The Covington has disks. Bingo. Covington seems to fit the bill. A floating seeder with disks.
Drawback. Why should I pay full price for a piece of equipment that I'm going to strip in half in order to use? Well, maybe because that's my only option. Hmm .... I think I'm going to contact Covington and see if they'll sell me just the seeder component minus the fert. stuff. They do, after all, sell the fertilizer component separately, PT-6A. I'm guessing, probably not. But it doesn't hurt to ask. If not, used market might be worth looking into at this point.
