I just checked my fuel usage on my Bobcat Predator Pro 61" deck G6 blades Kawasaki 1000cc DFI with 30 hours. I filled the right tank to the brim and then mowed for 15 minutes full throttle @ 3 1/4" in dry grass that was mowed last Tuesday so it wasn't dense. I refilled at the same spot on the drive way using a 1/2 gal pitcher and put in 1 qt at a time being careful and spilling none. It took 78 oz to fill mower back up so X 4 = 2.4375 gal per hour. How does this compare to what others are getting? It's about 25% more than I expected it to use.
