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.

Where are you located? I have a model 10A that has been sitting for years with what I believe to be an ignition problem. My engine used an early trigger switch ignition system (an early electronic ignition). Replacement parts are priced like gold, so I just parked it.

Today's Featured Article - Earthmaster Project Progress Just a little update on my Earthmaster......it's back from the dead! I pulled the head, and soaked the stuck valves with mystery oil overnight, re-installed the head, and bingo, the compression returned. But alas, my carb foiled me again, it would fire a second then flood out. After numerous dead ends for a replacement carb, I went to work fixing mine.I soldered new floats on the float arm, they came from an old motorcycle carb, replaced the packing on the throttle shaft with o-rings, cut new ga
