- Power Trac PT425 2001 Model Year
Here's a couple videos of my PT425 about 9 years ago. First one shows the turning radius. Note the tire tracks from the dirty tires as they form a perfect circle on the paved driveway. The rears follow the fronts exactly.

This one shows the "PT Pucker" in action. Watch as I back up carrying this huge chunk of a log. As I turn my wheel, the center of gravity changes and my right rear tire comes off the ground. As I straighten it back out, the center of gravity shifts back and the wheel comes back onto the ground. The log is 27" in diameter at the narrow end, 37" in diameter at the wide end and 53" long and weighs (insert some exagerated number here), well, we'll just say more than I cared to cut up and carry by hand! :laughing:

Here''s a link to my videos page with a lot more if you're interested. Just remember that this is a 2001 model PT425 and they have changed in design a few times with the engine placement, pump configuration, engine type, fuel tank type and placement as well as a now higher lift capacity. But you will get the general idea of how the articulation and oscillation from side to side works. Remember, the front and back sections not only pivot side to side in the middle, the front and back sections can pivot on the roll axis independently of each other up to 24 degrees (as I recall). This makes for all 4 wheels staying on the ground more on unevel terain compared to other vehicles.
