Interesting!! A local guy has a garden tractor with a 282 grafted into it. He's got wheely bars on it.
Not everyday you see a flathead V8 bolted into one of these, but there was an adapter kit, so it did happen. I saw one this past weekend at the Pioneer Powershow. Pretty freakin cool
Considering the Ford version was around 60 HP, and the later Lincoln one was 85 HP, it wasn't all that much more than the original 4-banger. Now, put Offy heads, a triple single intake and carbs, anice bumpstick, yadda yadda, and you got a tire-chirpin' tractor there.
Most 9N's produced about 23 hp at the flywheel and around 17 hp at the PTO (give or take). The difference of a few horsepower can make quite the impact on what you, as a farmer, are capable of doing. The choice between different pieces of equipment almost always comes down to horsepower. I am in the farm equipment business, so I see this play out almost on a daily basis. I'd wager that V8 9N makes around 45- 50hp at the PTO. That's a heckuva increase over 17.
I couldn't remember the four-banger's output, but yeah, getting more done in less time is a farmer's real need.
