I think you are clicking on today's posts at the top of the page. That brings up all posts for the day. The highlighted yellow ones are ones you haven't read. At the top just click on new posts and only the yellow unread posts will come up.
Thanks, George2615. That makes sense. I try to read all the current posts even if they are for different models than mine. Trying to learn all I can about these tractors.
I almost bought the same model, but I went with the XR4140HC for the few extra $$ just a bit bigger with more ground clearance (which I need), only $1700 more in my case. Congrats on the new Tractor, I just bought mine too.
