I used to have an 1987 diesel Kubota F2000 with a 60" front deck like the one pictured below. While it was a little large for my 1.5 acres that I mow, I LOVED having a diesel. I put 10 gallons in the tank at the beginning of the summer, and still had fuel left when I put it away. Unfortunately it had a stamped deck that was disintegrating and I couldn't find a replacement at a reasonable price so I've picked a Dixie Chopper 50" with a 22hp Kawasaki. It runs faster, taking my mowing time from an hour to 45 minutes, but gosh it gulps fuel!! I'm starting to think in the long run I would have been better off paying for a new fabricated deck on the Kubota!
I have noticed this as well, not in a mower, but in scissor lifts.... take the exact same lift, one will have a Kubota 3 cyl diesel, the other having a 4cyl ford gas engine. in the same use, the Kubota will go through 10 gallons a month.... the Ford... nearly 5 gallons a day... I really can't complain too much about my mower's 20hp Briggs V-twin... my rider has a tiny 1.25 gallon tank, but it will mow my acre of lawn (2.08 total) and putter around for another 3 hours or so on that tank.
