Been using the same riding mower for 20-some years. I have no idea how many gallons it takes to mow my yard. I just know I can't mow it twice without refilling. But I sometimes do it anyway and run out...
Some of you may laugh at me, But I paid 10K for this JD in 1996. has 800 hrs on it now. still runs like a top, with regular maintenance. Has a plow blade with 2 stage hydraulics , if I need it..23HP liquid cooled , fuel injected, Hydro static drive.
