My Iron and Oak BHVH2609 is about 4 years old and split about 25 cords of mixed hardwoods. Last year a friend cut a couple of large hard maple and oak. We used my machine to splitl the wood. It never failed to split even the largest and gnarliest crotch pieces. My buddy would look at me and smile each time he set one of these on the beam, his message being "Let's see it split this sucker." Some of these pieces slowed it a bit but it always powered its way through. Its engine is the Honda GX series with electric start. I service the engine each year and check the transmission and engine oil levels prior to each splitting session. Premium Sunoco fuel is used in all of my Honda engines. I've installed the log cradles and log dislodger which have proven their worth. No part of the machine has ever caused even a moment of trouble. I am 74 years old and had to stop hand spliting a number of years ago because of right rotator cuff surgery. If anyone were to steal my Iron and Oak i would purchase an identical machine in a heartbeat.
