It went through almost everything i threw at it. Worst was 18" x 36" oak narly sections. On a couple of pieces, I had to reposition them. Ok, it says to change the engine oil the first time after 5 hours. I did mine after 2. I recommend you do it after 1. Nasty nasty stuff after 2 hours. Changed it with 5w-30 synth wally mart brand. Oh, don't assume it takes a quart like I did. I had to pump the oil back out! It only holds 20oz. Hydro fluid stayed nice and clean. Don't trust TSC - check the bolts. One engine mounting bolt was finger loose. ...of course it was the inside bolt which was the hardest to tighten. I also think it was upside down. Anyone else have the inside bolt mounted with the nut on the top?! The two hitch bolts were rediculously loose - I'm glad I didn't tow it home. The bolt holding the wedge on was not tight. I also took the beam off and greesed the hinge pin. It swings nicely now but vibrates like crazy when running. I'm not sure how much gas the tank holds, but it sure seems like a small amount. It's easy to overflow. Engine starts easy if you prime it. ...don't they all when new!
