How do I make a John Deere tractor with fondant. I've never done anything like this before and I need some serious help. I want to make an awesome John Deere cake for my son's third birthday which is coming up. Any help would be greatly appreciated. Thanks.

HTH
The following link is one that I think would be a lot easier for me to do for the first time instead of trying to actually do a (i guess you would call it) 3-D tractor.??

If anyone has any helpful tips I would greatly appreciate them!!!
I'm not real clear on the size of the cakes or even how much fondant I need or even when to add color!! I guess I'm not really sure on anything. lol.
What flavor cake is good, can I make the layers different colors?? Like green and yellow, if so how??
With this being my first cake would it be easier to make them square layers or leave them round??
Exactly what does it look like this person used for the clouds?? Marshmellows??
Any helpful tips would be greatly appreciated!!!
Here is one I did last year for a grooms cake. It really wasn't too difficult. I used the Wilton train pan. Its an old pan so you have to look around. You just cut the front off and shape it a bit and you have a tractor. This one was covered in fondant. I used leaf green in the Wilton color gel. The bottom cake was buttercream and it has graham crackers for the dirt. Look in the forum section.. I believe there was a thread on this awhile back.
No problem! 
Check out all the John Deere tractors in the gallery. I got inspiration from those.
hey! I think you're the one I talked to at the book store the other day! here is the tractor that i made.

haha I am the one you talked to!! That is a pretty awesome cake!!! The people are great!! I am going to get started on my son's cake this week b/c his party is saturday. I think for my first one I'm going to attempt to do the one that I have posted around here somewhere. I have a full time job and I don't get home until late so I think that one would be easier. lol. I believe I am going to make the mm fondant Wednesday b/c I've seen where people have said that it needs to set for a couple of days. Think I'm going to take friday off to have the whole day to do the cake!! Thanks for ur help and keep checking ur messages. lol. I may need you!!
How many people do you think that cake (the one I mentioned in one of my posts) would feed?? What Size pans do I need?? How much fondant would I need?? Does anybody know a really good marble cake recipe?? I'm so full of questions and don't know the answers!! HELP!!! lol!! 
The 2 tier cake you posted above? Just depends on how many servings you need. I normally do a 8/6" or 10/8". I use the Wilton serving chart.

To cover a small cake 8/6" it takes me about 1 batch of MMF.
