I have 2 of the Countline 40 ton units. I bought the first one about 5 years ago when the first came out with the 40 ton. My old splitter was a Husky 25 ton unit and it would split ok but it struggled and wouldn't split live oak at all. Live oak would make it just stop and it never split a single round.
When Tractor supply came out with the 40 ton unit I looked it over and I liked every thing about it.
My 40 ton splits live oak like it not even there.
I also liked the 10'' wedge and the 9.5 cycle times. Every thing on the 40 is bigger and more heavy duty.
I put a hour meter on it the day I bought it, and it has 1264.6 hours and my newer one has 186.3 hours.
I was so impress with the first one I bought another one as a back up and so I can have two splitting stations. It splits forks and knots like butter. It doesn't mater how you orient the forked round it just bust it open with ease. I paid 1, for around seventeen hundred. The new one I paid eighteen hundred.
I had to search for the second one and I finally found one about 80 miles away. It was a long drive but I got exactly what I wanted.
