i fueled my BX2350 and mowed my 1.5 acres 3 times and it still reads near full. is this correct? im guessing i probably run the tractor about an hour every time i mow, so that's about 3 hours of operation. i keep my lawn fairly short to keep the clipping mess to a minimum, i generally mow every 5 days or so. i run the tractor at 2,600-2,700 RPM while mowing. i see no need to run it at wide open throttle.
