My dealer has a couple of Toro 62" midmount ZTR's he wants to sell real bad. Price seems right on both, but I don't know which one will be the most dependable and do the best job. One has a 23hp Kohler air-cooled engine. The other has the new 26hp? liquid cooled engine. I have had good luck with my 22hp Kohlers,and have heard all the stories about the 25hp's. I don't know anything about the 22hp eng. or the new liquid cooled eng. Anyone here know anything about these 2 engines. I can't afford to make a $7500 + mistake. What are the pros and cons? Thanks.
