Just purchased a used Cub M60 Tank and mowed for the first time time. It has the 25 hp Kawasaki engine. Really impressed with the cut and how it drives. Have a question however about the fuel consumption. I mowed for about 2 to 2 1/2 hours and seemed to go thru about 4-5 gallons of gas. I didn't monitor the actual usage, but in general how much fuel do these engines burn?? If my figures are semi close that's 2 gallons per hour--sounds like alot! I'll try to get a more accurate reading next time I mow. Just like to see what anyone else has found with this engine.
