It is a Timberwolf TW-5. I don't know how old it is nor does the owner. The tag with all the info is ripped off the frame. The guy selling it is a tree service company I have known for 15 years. They do a lot of work and pump out a lot of firewood. They have several other processing machines and they just bought another monster. This was never really used as a main source but The machine definitely has seen thousands of cords. They claim to really maintain their equipment which I can see just by looking around their yard. It has electric start but there was no battery hooked up and it started with 2 pulls. The only major thing wrong is the push block. They have welded the brackets that ride on the I-beam several times and it obviously is broken again. The I-beam itself is perfectly flat on the top but it is worn unevenly underneath where the brackets ride. It looks there shoulkd be a cover plate where the engine shaft is connected to the pump. The muffler is missing the the heat shroud and is pretty loud for a Honda and exhaust leaks from the screw holes where the shroud attaches. The push rod cylinder shows no signs of leaking and slides in and out smoothly. I didn't try to split anything with the way the push block is for fear of doing damage. There is some grease/oil build up around the controls and the base but not much. I used a TW5 that a different friend has and it is a beast. That one actually had more grease/oil build up then this one and would drip on my driveway. I spoke to a Timberwolf dealer and he said the push block is $600 and the I-beam is $1500 but as long as the block is welded securely and the I-beam is flat there would be no need to replace them. I guess I should have him weld the block on and then let me test it for a day to see how it handles under load.
