I have the 30 ton, and don't see the need for a 37. That being said, I love that splitter. Does everything you ask it to and then some. Built very well. I love that it idles down when the wedge is retracted, especially when you're splitting by yourself. Gets nice and quiet instead of screaming wide open the whole time.
The throttle cable rubbed a hole in mine, I think I mis routed it. Gave them a call (splitter was almost 2 years old then), they sent out a new throttle cable free of charge no questions asked. I'd highly recommend it. The Honda engine on it has been living up to its name, and always starts easily.
Below is a pic of what I've split with it, including some really gnarly stuff with knots etc same size as that log.
