I allso have a 3&6 year old. My husband and I think this is the best money we ever spent!! They both love the tractor.

NO, NO, NO!!! I did not purchase this from Walmart but it is the same thing. I got ripped off by $30 more than Walmart's price! I bought this because it was rated for 2 - 7 years, my 4 year old is probably going to outgrow it by next summer, we are hoping he can use it one more season. This product is only suitable for up to 4, maybe 5 years old (and depending on the size of your child). My son is not large or small, but rather average. The directions are horrible, only pictures, and the item list does not list things separately. The trailer is VERY flimsy. I am not satisfied in any way! I DO NOT RECOMMEND!!! If you want the special child in your life to get good use out of an item and make the investment worth it, do not buy this! For 3-6, I personally think the big/2 seater tractor is perfect. I wish I would have purchased that.

No, sorry, it takes about thirty to forty minutes to put it together, but you'll only need a couple of tools, nothing strenuous.

Yes it does come with a 12V. I bought one last year for my twin greatgrand sons and now have to buy another because they love it!!! They have other ride on but love this. I suggest you buy the Insurance on this which is fantastic. I had asked if this was a Peg Perego because that is the one I bought orig. I believe it also comes with a 1 yr warr from the mfgr.

yes 12volts
