Gordon - The trailer is parked in the Rottweiler kennel, which should give you an idea of the size of the kennel and how many dogs guard it... /w3tcompact/icons/laugh.gif
The 19.5LR24 rear tires have a larger rolling circumference than the stock tires, so the front tires have to be larger, too. I got the wheels custom made by OTR. I'll dredge up the part # and contact if you need it. I think I gave it to Rich, too. The rear rims are stock, but the rims are the minimum width that will still work.
Unfortunately, as far as Dad's garden is concerned, the red clay is a permanent aspect of it, I'm afraid. If you can till it thoroughly at the right moisture content, though, it'll sure grow a good garden.
A funny story about the tiller modification: My dad has a neighbor in his 70's who's been a farmer all his life. He's got a couple of big (relatively) JD's and a big MF. He always manages to show up when I bring the tractor to Dad's and usually manages to bad mouth my tractor for some reason. Usually, he makes a prediction of some sort about the limited performance of my "toy" tractor, then sneaks off without saying anything when it doesn't happen the way he thought it would. So, when he saw the scarifier teeth on the tiller, he said "Did you bring a chain so I help you pull them teeth through that clay?" I'm careful not to be cocky around this guy because if I am and he's ever right, I'll never hear the end of it, so I just said "Yeah, I made sure I brought plenty of chain, but it's only G-80 3/8", so go easy on it if I need help, ok?" He laughed and we were off on a non-combative start. About the time I made my 2nd loop around the garden plot, I saw him sneaking off across the field back home. That's about as close to a compliment as I'll ever get out of him...
