I purchased this tractor for my 5 year old son but the whole family love it, particularly his Dad! Its very easy to control and easily goes over different terrains outside including chippings, concrete and grass. We have used rechargeable batteries and they last 2 or 3 hours of constant use. We were originally looking for a car but soon realised having a tractor would be better for use outside and you could hitch on a trailer. Buying a trailer to match though is not so easy as I soon discovered each model tractor has a different type of hitch. We brought the Big Farm trailer shown on the same page but it didn't fit the hitch. However my husband managed to do some alterations to make the trailer fit and its a great addition. All in all a great toy.
