Kjc, I'm sorry for the late reply, but life gets complicated at times.
I,ve had my PT425 for about two months. I live in Oregon, so shipping was a rather expensive $1,500; that was for the tractor and two pallets of implements. If you have a choice don't use Overnite Freight; they took forever and the tractor had lots of paint missing when it arrived.
I purchased a 60" finish mower, cement mixer, post hole auger, small and large buckets, rake, forks, boxscraper and snow blade. I've used the mower a lot and it works well; it's nice having it mounted on the front. The cement mixer is also handy; you can mix and then dump it right in the hole. I haven't used the rest enough to really give an honest opinion.
The tractor has worked well after one initial problem. When it arrived, the throttle wasn't working properly. The low end throttle stop on the engine is too flimsy, so when you throttle down the adjustment screw goes past and gets stuck. Once I realised this I was careful not to push too far forward on the lever; but it's something Kohler should take care of. Other than that, the tractor has run great. I love the auto attachment feature; easy to do and easy on my back. As WP has already said, driving an articulated rig takes some getting used to.
Like everything in life, the Power Trac has it's pros and cons. The front mounted attachments are great for mowing, plowing snow, post hole auger, etc. but not so good for rakes and boxscrapers. The hydro drive is nice but you can get in trouble if you're operating at high rpm; it moves Fast!! All in all I'm pretty happy with my purchase.
