Basic same engine made in the same time frame when reg grade gas at a gas station was 95 octane and the bargin gas was 93 octane . A stock gas tractor from 63 up to the last built in 75 ran on the 93 well a little better on the 95 . Now lets fast forward here to today and the what they call gas . It BURNS way HOTTER and faster , the replacement engine parts are NOT the same , the pistons now are a CAST piston not a FORGED as Forged will take more heat due to the close grain wher as the cast does not conduct the heat to the skirts and into the walls . Then NON of these engines are what you can call true stock as each and everyone of them have had the heads off god only knows how many times and been mill/ ground down for warpage and valve jobs so with each grinding the compression ratio goes UP and when you hick up the compression ratio you need MORE OCTANE to cut precombustion . WHILE we could get REAL 93 octane we as in ALL my close friends got along just fine with the gas tractors , we did everything with them that they were meant to do from plowing all day and into the night disking planting haying chopping corn picking corn cleaning the barn moving snow . Yea 93 cost more and it ran us around 150 200 bucks more a year for the 93 over the 87 BIG deal . BUT they changed the gas once again and we lost two 706's in two days from the gas that came from to different sources . one of my other friends that has a 460 gasser and is having the same problems with it when it comes under load it starts to seeze up . So this is what we have went thru . You get the oil companys to make us some real old fashioned 93+ octane gas no lets make that 95 octane and i don't care about the lead with NO AL-KI-HOL and then ya can go play with the old gassers . IMHOP the tractors under the 90 Hp. for the part time/ Hobby farmer were great , they started in all weather with a good tune up and a good battery thy as in the tractors like the 544/656/706/ 756/ were a super chore tractor / would do great pulling planters and OLD drills , great on the baler and mowers did well on the pickers can't tell you how many loads of manure they put on the fields ground unseen numbers of feed thru and 855 mill , the only thing where our 706's lacked was the onset of the new silage wagons , asking a 706 to drag 35-40000lbs was asking a bit much there they lacked in two department (1) Horse power and (2) weight .One weighed in at around 96-9700 lbs and the other with loaded tires and a few extra weights went around 12500 . NOT enough dog for the tail. Not on our ground . NOW i can tell you there will be the EXPERTS that will tell you i don't know what i am talking about i only worked on I H tractors since 1983 FULL time as my living and been building engines since back in late 63 . BUT you do as you want.
