806 gas burners

Hey all, I found a nice looking 806 gasser and am quite interested in it. I haven"t ever really been around any gas tractors of this type. I was wondering about any pros or cons you guys could help me out with. I"d also like to know how many were built as gasoline tractors. Thanks, DK

the tractor vet is the captain of these tractors.mension 706 or 806 he'll be here.

I have a diesel that will burn about 4 gallons an hour at PTO speed (baling, swathing etc), I haven't done any heavy work with it yet but was told by the guy I bought it from it will burn around 6 when really working (he also told me that it had been turned up so maybe their not all this bad for fuel economy).
I have been told that the gassers will burn about 20 percent more than the diesels.

They are a good tractor for what i know but i do know they like fuel lol!

YEa it is a good tractor BUT like everyone said She do like her gas and she ain't not TEA TOTALER . Rule #1 She needs 93 octane gas no if an's or buts about it Rule #2 use nothing but LOW ASH 30 weight engine oil in it . If you do not intend to do tillage with it then drain any fluid out of the rear tires and it will ease her fuel use a little. Keep the engine in tune and ing. timing set to spec.'s and it will do fine . Myself i do not care for the C301 because it does not have sleeves , and the fact that a gasser of this size just plum uses to much gas . Now get a 806 Diesel and oh yea.

Hump, you were pretty sure that i would come on weren't ya. Good thing i was not in Grouch mood this evening.

Ok thanks for the info. I won't really be using it for any tillage work, mostly just on a v rake or an 8 ft shredder or for dragging the yard. I like diesel better too but this tractor is in nice shape with good paint and the price is right. Also thought it might be a good idea to have a gasser around the feedyard in the winter to run the pto generator because of cold starting issues. It can get pretty cold here in central Nebraska and if we have no electricity to run the mill or the well we are in a world of hurt!!

Be just fine for that just follow what i have said and you will be fine just do not try and cheat on the gas to save a few cents as you will learn fast that few cents you tryed to save will cost you a engine.

ya, i had that feeling you'd be in.

Not this crap again.

Just don't let you set the timing on it....

I am going to put this in plain English for you . READ THE OWNERS MANUAL .

Any time you want to match me on tuning a engine or building one let me know .

Retard the timing a little and you can get by with that cheaper gas.

You want to run the "cheap" gas in those engines!!! They are designed to run on 87 octane or lower... The higher the octane,the harder it is to make the fuel burn effeciently... lower octane burns at a lower temperature!!! This is what most people get mixed up on!!! Go ahead,burn that high octane,high dollar gas and see what happens!! You'll foul out plugs within a week!! Use a good hot plug and run 87 octane and you will never have a problem! I have 6 IH gas tractors and use them and never have any problems...

Actually if you set it right you'll be just fine. Millions of hours on thousands of tractors are proof - not to mention the fact that todays 87 octane is 1960s/1950s 93 octane.

Tractor vet just doesn't want to admit he fried an engine then screwed the owner by blaming the gas.

4 to 6 gal a hr is pretty high for a 806 diesel. I have two 806's , 856 , two 1466's and a 1486 all diesel. I don't pull a plow anymore but back when I did with a 806 diesel mine burned about 3 to 3 1/2 gal a hr pulling 4-14's. I still pull a 18 ft disc at times with one of my 1466;s and it used 3 1/2 to 4 gal a hr pulling it. The only thing I use these tractors today for is in the hay field. I use the 1486 pulling a vermeer 605 super M round baler and i can run it baling 2.8 to 3 gal a hr.

Vet. All the older mechnics, thats over 40 lol, in the aera where I live that worked on older gas burners pretty all agree with you on the gas to use in thoes motors. I was told that gas with 87 to 89 octain 40 years ago is a lot different than the same octain rating today. Was not blended with corn back then and it was leaded gas and low octain regular then was 89.

RIGHT ON MAN. At least someone had the guts to tell the truth

Reg. gas back in the that era was 95 octane and high test was 105 or better depending on who's you bought . Sunoco 240 was the lowest i could run in my built 390 and it was 105 . Usually ran 260 on the street and for the strip i went one notch above that . Back in 68 and 69 Ford offered two versions of the two BBl. 390's one was a reg . gas and one was a prem. gas . We had lots of problems with the premium version with customers thinking that they could just run reg. in them Gulf had the lowest grade gas called Gulf Tane and it was around 91 -92 octane and it would even make a 6 cylinder Chebby pick up ping and knock. Gas started going down hill around 74 as far as octane and the end of the gas tractors was close behind it . That is when we started seeing problems starting with gas tractors. and also no when you get and overhaul kit they are no longer FORGED PISTONS , they have gone to a CAST alu. piston and they can not get rid of the heat as fast as a Forged piston.and this is the main problem ,HEAT . Today you can not build a engine to go play with and run pump gas with much over a 9 to 1 compression ratio and that is a play engine. Not a working engine . Even my S/MTA does not like 87 octane . I got it out the other day first time in 11 years i have had time to set down and do anything with it and after going thru the carb and getting that old nasty gunk out i dumped in some 87 octane that was fresh in a can and she fired off ok and while i was adjusting the carb and getting it charging again when i went to shut her down she dieseled and little even with the idle set at 450 , why because the 87 burns somuch hotter , it is blended to burn hotter for emissions on CAR and light truck engines. The 93 is a cooler longer burn and it is as close as we can get to the old gas. Over here everybody i know has atleast one if not more gas tractors that get used in everyday farm operation . My buddy and i only have three diesel tractors and the rest are gassers. We have the 1066 and my 806 and his boy's 720 Deere . The 706 is gas the J/D A and a farmall h . Neighbor has two S/MTA's a WD 45 a Late model 8N a Farmall 400 and a Farmall M that do everything on a working 40 head dairy farm . My other close friend milks 45 cows and farms about 275 acres and has two diesels and everything else is GAS including the combine.We all have gone to getting the 93 octane and have no problems working these tractors where it was a constant fight . we just Read the owners manual and it states wright in there the Minimum octane and again i said Minimum octane requirement for that engine. Most of these tractors are one owner tractors bought new on the farm and have worked everyday since new . Other then two S/MTA's and the two 706's that my friend bought off me and they have had them almost twenty years .

I do not know why i respond to idiots like you BUT TODAYS GAS IS NOT THE SAME . BUT i have a Lab report on the gas and this is where I LEARNED something . BUT since you KNOW IT ALL and probably never built a engine in your life or headed up a drag race program and kept two cars at the top of the list or built several pulling tractors that were at the top of the heap or built your own car that was far better then the rest Butyet you want to bad mouth me . If i could figure out how to post the lab report that we paid out good money to have done let lone hand delivering it to the lab a 165 miles form me to have the gas tested to confirm what i already knew what happened . Then have it happen again when a new guy brought the wrong gas to the farm and she melted down again WITH THE TIMING SET TO SPEC.'S donj't set there being a CB rambo trying to impress someone . Go put some 87 in and old car engine and run it WITH THE TIMING set to spec's and see the results. Read some books on building engines on max compression ratio for today's gas . And like i said ya want to try and match me on working on tractors lets get together and we will see what ya know . as i know you are some young pup that is still wet behind the ears with a big mouth . I ain't hard to find.
