We have a vertical/horizontal MTD yard machines 20 ton log splitter and the engine just died it seems. Not sure of exact age but 15-20 years old. Was running it, lost power, started smoking and now it's locked up. Trying to decide if better to but a replacement engine, heard good things about the harbor freight predator engines or buy a new one. We have a Tractor Supply just down the road from us that sells county line splitters, 25 ton around $900. Nothing else has ever been replaced on current splitter. I am not sure how much wood we actually go through but we just burn wood to heat the house and water all year round, not really selling any at the moment. It would be nice to have all the options like a log lift but really can't justify the price of those. One thing I am curious about is the quality of new splitters vs old ones. I know the quality of many things have gone down hill and would imagine it has affected splitters too. How well will a new one hold up? About the tonnage ratings, how does the tonnage rating on a new one compare to an old one. Will a new 20 ton handle the same stuff as a 20 year old 20 ton machine?
