I purchased this at my local Wilco Farm store on sale, 3 months ago.
I‘ve had to remove quite a lot of alder, they were getting dangerous, & falling over the fences In storms.
I’ve split 10 cord with it so far, will cut another 6 next spring.
i’ve been very pleased with it so far, & will get most of my $$ back when I sell it next year.
the logs in background are 18”-15”, with some smaller.
I split In horizontal position, vert did not work for me.
I made plywood tables for both sides, makes it much easier, & protects the gas tank from falling pieces.
as always, YMMV, just my opinion.
