Looks like you have a good helper. My son's are 6 and 17 months. There a big help now. Take about three times longer with there help but the fun we have is outstanding!!!!/w3tcompact/icons/smile.gif/w3tcompact/icons/laugh.gif They both love our tractor and I can't wait until they can get there seat time.
Take care
Looks just like mine without the son. Mine is 7 and hopefully he will be able to do some work with it in the near future. He and his brother who is five have driven it slowly with me right there. By the way what size tiller is that you are using? I have considered getting one.
