I just filled up on fuel for the last 6 hours use. I was suprised when i looked at the hour meter and it was only up 6 hours. In that time I have installed some equipment, pulled a small chissel plow, pulled a small 2 bottom plow, rototilled in some straw and used the rotary cutter to cut some paths for my daughters razor. I did a lot of stuff for a short time.

12 gallons of fuel.

Yup, 2 gallons an hour.....

I used our 15 foot chopped to cut a field of clover down so we could plow it today and used less fuel with a 35 year old 175hp IH (1586).

I am not suprised that it eats fuel, but I expected about 1.5 gallons an hour or less since I have not been pushing the tractor at all!:kidw_truck_smiley:

Even then Brian, it looks like you might have been taking it easy..According to the Nebraska Test Lab, your 4520 burns 3 Gal an hour:

From a HP-HR/Gal standpoint, the big ones ARE more fuel efficient....I'd say your correct when you say your 1586 uses less fuel.
