I was a bit skeptical after having had a bad experience with another log splitter that didn't work from another seller. The SuperHandy 20 ton splitter is awesome. I was able to assemble it in about 2 hours, with 1 hour more to review the instructions and the motor manual. Be sure to do both before assembly and start up. Parts for each step not in same bag, but not that many that it made assembly harder. Some paint was in holes, so start the bolts and remove them before assembly to remove the paint. Paint job could have been heavier, but overall not bad. Step 5 says need allen wrench, but you need a 17MM socket. Step 6, be sure to remove the plastic dust cap in the hole. It wasn't easy to see it in there. Also step 6, be sure to loosen the hose nut at the ram before trying to connect the other end at the tank. Don't strain the hoses. Cheap wrench included. I didn't use it. I used a 10MM, 13MM, and 17MM socket, 3/8" drive with an extension, plus a few adjustable wrenches, with one at least 12" in size for hose connectors. There are 2 oil drain plugs, but no extended piping. I'll probably remove motor mount bolts before draining oil when I change it and add some elbows, pipe, and a cap at the end so when oil in motor's changed, it's easier and doesn't make a mess on the splitter frame. I may add hard rubber motor mounts too for anti-vibration, although first few logs I split didn't show excess vibration. They would help raise the motor enough for the oil drain piping I'll add later to clear the frame too. Be sure to wiggle the hydraulic hoses as you connect them to make it easier to thread the connectors on and prevent cross threading. If it's going on hard, it's probably going on wrong. I assembled this myself and I'm 71 years old, but a helper would have been nice to install the heavy ram. Running the bolts in and out first to remove the paint on the internal threads helped a lot in putting the ram on. They included a nice, plastic funnel with a long neck for adding the oils. Be sure when installing the clear tubing to push it on all the way and have the worm gear clamps nearer the end of the hose when you tighten them. Put the worm gear clamps on the hose before installing the hose. It sucks when you forget and have to try and remove the hose. The ends of the hose could have been cut cleaner, but I didn't have any leaks. I got it ready and fired it up. I cut a few 5" logs with no problem. It split them right in half. One with a knot got caught. I was able to put a shorter log in behind it, snug the ram to it, and then step back as the ram continued on, easily splitting the first log completely. I'm impressed. I spent $59 on the 3 year extended warranty, but from what I see, if you keep this machine maintained and don't abuse it, it'll last a long, long time without issues.
