I don't mind your comment, or even disagree with it maybe.
However, many times folk come on here with questions and list some partial info on what implement/ device they are talking about.
He never mentioned it was a John Deere mower, he mentioned it was a No 5 is all.
That is kind of like talking about an H tractor. I would assume it is a Farmall, but it could be a JD, hard to say for sure.
Many other tractors and implements 'share' a model letter or number.
Perhaps my message should have simply been:
"What brand of mower are you talking about?"
But that seemed a little short, so I added in some extra comments and speculation.
The same speculation you did, that it is actuually a JD mower that he is talking about?
