Pleased it’s running ok, quite a few Farmall’s in this country but I can’t say I’ve ever seen a petrol powered one here. Beautiful countryside where you’re situated ,looks great 👍. Regards from Down Under.
Gasoline (petrol) was the primary fuel here until the middle 60's. Diesel was becoming popular but we had LPG in the mix also from the mid 50's till the late 60's. Diesel power won the game but Gasoline and LPG machines are still out here doing work.
My father had an old Allis Chalmers tractor in the 1960’s. I remember starting it with petrol and when it got hot you would switch it over to kerosine, which in those days was cheaper to run. It was a mungril of a thing, had a crank handle for starting, you didn’t dare stall it for fear you’d never get it going again. It was high clearance with mid mounted scarifiers, looked like a praying mantis, not very easy to handle compared to modern tractors.
My F20 was meant as such. Started on gasoline and switched to kerosene once warm. It runs on gasoline only now as kerosene is more expensive than diesel and gasoline put together at times.
Getting the carb fixed so it will run at 2070 engine rpm for 540 PTO rpm instead of WOT will help the fuel economy a tad bit as well. That 6 foot bush hog will not be terribly under sized if you narrow your wheels some, Looks like you got lots of room to narrow up if desired. I do realize you are in hill country so wide spacing has some stability benefits, but I would find that sweet spot for all around hay tools work that you plan to use and still have stability.
Since it runs good everywhere but going up hill? Wondering if float level is incorrect. Or as mentioned in my other post that solenoid looking deal on the carb are known to be problem childs. Lots of people replace that thing with a normal main jet and manually adjustable needle and do away with it.
