bought a extra clean perfect running 630.owner said he broke 8 acres of 50 year old sod with 3pt.3/16" plow in 2nd.gear at 9 inches deep.he said tractor handled it well however he used 32 gals.of gas to do it.tractor has 3 wheel weights on each rear wheel and a wrap around weight on front.have i bought a expensive to run gas hog?tractor does not smoke and seems to be perfectly tuned.my 1020 would not use near that much fuel on 8 acres.can i afford to work this 630?

thanks fellas for the come back.a coupla of you made me feel better about buying the 630.by going to 3/14s and a 10ft.disc(don,t know if a 630 will pull a 12 ft.disc.) mabe gas won,t be too bad.weighed tractor at feed mill the other day and was 7770lbs.w/ weights as specified above.tractor has never been pulled or shown,but was used for hauling irrigation equip.around and bush hogging most its life,so hasn,t seen much heavy duty.

I have a 620 and a A that I have used for various things over the years and I have seen the A burn almost 10 gallons of gas an hour. (A 49 gas) Granted it was pulling a round baler that was designed for 75 or 80 hp and we were baling until that last stroke and then stopping and wrapping the bale. I have sen the 620 work hard (never quite as hard as the A pulling the baler and we didn't have the 620 when we used the A that way or it would have been to the baler) but pulling hard to a disk that according to my dad was for a 720 burn about 4-5 gallons an hour. So the consumption you heard about was probably about right for that particular job. And the duplex carb is much more efficient than the single barrel carb. And under lighter loads it won't burn that much.

If you work them you have to feed them. Hard plowing takes fuel. a 630 running and not working hard will take 2 1/2 to 3 days to burn the 17 gals of fuel it holds. Jon

I have a late A that will burn 3 to 4 gallons of gas an hour running a 4 row cultivator in 3rd gear. The cultivator does use 8" sweeps.

We farmed with pre-war JD A's for YEARS, and you could automatically figure 2 Gals Per Hour.....no matter what the tractor was doing. My Nebraska Test Book is still in storage so I can't verify the 630 test for you right now, but just suffice to say that when you pour gas in a tractor you have somewhere around 12,500 BTUs Per Lb of fuel whereas Diesel is 18,500 BTUs Per Lb. There is a lot more "HEAT" in a gallon of diesel, and the engine in that tractor is a "heat engine".

You are a little confused on the gasoline vs. diesel comparison. While diesel does have a little more energy than gasoline you can't compare it by weight unless it is metered by weight. Diesel weighs more than gasoline so btu per pound is inaccurate. The proper comparison is by volume because it is metered by volume. _gasoline= 115,900-125,000 BTUs per gallon
_kerosene= 121,500-135,000 BTUs per gallon
_#2 diesel= 138,000-140,000 BTUS per gallon As you can see with the energy btu overlap/ diesel can be substantially more than gasoline or it can be only slightly more.

The 620, and 630 set all-time records for gas economy....you can't buy a more economical gas tractor, today..!!! Believe me, if you are breaking 50 yr old sod, 9" DEEP...you are using SOME POWER...and the horses have to be FED, nomatter what kind of fuel you are using.!!! Add to that--you have NO starting problems in the winter, and you will be happy...!!!!

Haven't you noticed that there are no gas burners being made today....you might get more efficency if you go to electronic ignition, but I doubt that you can afford to do any serious day in and day out work with them. I had a cub farmal and it used 3 times the fuel that my JD 4400 does even 16 h.p. vs 35 h.p. The 630 is an antique tractor.....
