The Parkland (s / er) petrol log splitter is the worst product I have ever had the displeasure of assembling (including Ikea furniture). For the first half of the manual (it turns out) showed pictures for another model. So I put the entire back half (axle, engine, etc) on backwards. The kohler engine had the id engine tags supplied on a piece of paper and you physically stick the id numbers on - thats worse than briggs stamping it into the cowl.

The welds looked awful, and one entire bracket was welded on backwards (the arrow that pointed forward in the manual was actually welded on to face rearwards. The rim for one wheel was warped from the factory.

I have heard some good things about the homelite 5 tonne (probably same as ryobi), but I was just at bunnings and they do look a bit of a toy. But would probably do the work as exfarmer says
