acres per gallon

I did some fuel record keeping this spring with a Deere 4650 power shift and a IH 1086. I don't know if these figures I came up with are in the ballpark of what fuel consumption should be and I only checked it ONCE for each tractor with the implement it was pulling so the figures are far from scientific. I'm not starting a color war, just throwing out some figures. So here goes

1. 4650 on 1000 gallon sprayer 60' boom spraying 28% nitrogen 40 acres per fill-- 1/8 gal/acre

2. 1086 same sprayer spraying Treflan w/water 75 acres per fill-------------------1/10 gal/ acre

3. 1086 on 12 row Deere 7200 planter w/o fertilizer at 5.5 MPH -----------1/4 gal/acre

4. 4650 on 30' field cultivator 10th gear 6ish MPH pulling hard-----------------1/2 gal/acre

When I sprayed I had to come home to refill but it was no farther than 2 miles. Tractor ran while filling to agitate so the Deere came home to fill darned near twice as many times. I don't know how much that affected the fuel consumption.

So there it is. Like I said this is a ONE TIME ONLY check. I did it per acre instead of per hour because per hour means nothing to me. Let the bragging begin!!! Jim

A lot of factors could be involved. Fuel pump settings, dirty injectors, timing, dirty air filter. I've pulled a 12 row planter with my 986 and it does not demand a lot of fuel. The field cultivator will make a tractor work and therefore burn fuel.

Last summer went 3 miles down the road, sprayed 40 acres of pasture, 200 gal tank, 38 foot boom.Came home topped off Farmall 95 Tad less than 2 gals. 1/20 th gal per acre. Four banger turboed, intercooled FIat/Ford 95hp motor.

Come to think of it, way back in the early 70's I started farming with a 1070 Case. It just loafed along pulling a 6 row cultivator and used a very small amount of fuel. When it was pulling hard I thought it might have used a little more fuel than it should have for it's size. I kept track of gallons and hours at that time. I traded the 1070 for a new 1086. The 1086 used more fuel loafing along on the same cultivator but less fuel pulling the same plow, disk, etc the 1070 used to pull. The 1070 was rated at 108 non-turboed horses and the 1086 was rated at 135? turboed horses, 1070 had a German Bosch inline pump, the 1086 had an American Bosch distributor type pump so I was not comparing apples to apples.

IIRC you have a CIH Farmall 95. According to Nebraska test #764(PTO fuel use @ PTO speed:5.2 gal/hour [19.7 l/hour]) so it must have taken you less than 30 minutes to travel 6 miles and spray 40 acres. 6 miles traveled(3 miles to & from field) @ 20MPH requires 18 minutes.

neighbor has a 4960 jd hooked to a 6 row strip till rig,he said when the employee ran it he would throttle back the engine a couple 100 rpms said it operated smoother to him,of coarse he disagreed, he himself would it at full throttle,but was amazed at the difference in fuel consumption, he said with the employee a tank would last all day with him at full throttle weren't no way and very little difference in the amount of ground covered

The only true comparison is when using each tractor on the same machine, under identical conditions. None of these are equal.
