I'm going to have to agree with most and say it depends on the dealer. If they have exactly what you're looking for and they need to move it then that is when you'll get the best deal. If I had to guess on seasons, though I'd say Spring is probably the busiest time for them. Guys are buying stuff to work in their yards and farmers are buying stuff to gear up for planting season. With that said I did buy my Case Farmall 45 in March this year. My preferred dealer ended up having a 2010 model on the lot he wanted to move. I got it for about $10,000 off MSRP and $5,000 cheaper than any other place in two states. I came in looking for a Kubota. He quoted it out and wasn't even going to show me the Case until I asked.
