I'm assuming that you have a Gravely Commercial 10A that was made in the early 1970's. Prior the Commerical 10, all the two wheel tractors used a Gravely Engine. The first switch was the Model 10 which used a 10 hp Kohler engine. Replacing the Gravely engine which ran at about 2800 rpm with a 3600 rpm engine worked, but it took someone young and nimble to keep up with the ground speed. The next model was the 10A with a change in gear ratios to accommodate the higher rpm engine. They also made a Commercial 12 with a 12 hp Kohler engine.
I'm assuming that you have a Kohler K241 10hp engine with a spec number of 47232B. My memory isn't so great these days, but I recall that the crankshaft was unique to the Gravely application. Later (but similar) Gravely models used the Kohler Magnum series engines. I believe that Gravely also made a few models that used other brand engines.
Some years back a fair number of people converted the older Gravely tractors to more modern engines. Adapter kits were required. I recall that a fellow named Bruce Guthrie made them.

Today's Featured Article - Third Brush Generators - by Chris Pratt. While I love straightening sheet metal, cleaning, and painting old tractors, I use every excuse to avoid working on the on the electrics. I find the whole process sheer mystery. I have picked up and attempted to read every auto and farm electrics book with no improvement in the situation. They all seem to start with a chapter entitled "Theory of Electricity". After a few paragraphs I usually close the book and go back to banging out dents. A good friend and I were recently discussing our tractor electrical systems when he stated "I figure it all comes back to applying Ohms Law". At this point
