Those measurements don't match the smaller Briggs motors but they do match an 8HP I have so I'm not sure at what HP they change. I know I did get caught fitting a 6HP Chonda on a small Greenie a few years ago. It was claimed to be Briggs pattern, had a 25mm shaft but it turned into a terrible job drilling the new holes to get the motor in the right position so the belt tension was right. I'm just wondering, as I didn't think about it before, but maybe that motor was a push mower Briggs pattern. I also have a 16hp twin here but as it is still in the mower it is a bit too difficult to measure. This might push that project a bit further up the list now. A few weeks ago I also came across 2 push mower motors with 25mm shafts and this just clouds the water a bit more, the only reason I noticed was when I went to change the boss on them . One was on a Greenie push mower with a Briggs Quantam motor that had from factory the blade carrier welded to the boss. I had to end up cutting the blade carrier off and destroy the boss to get it off.
No way you would need a 20HP motor on your Greenie and one thing you must think about is these motors do not have a fuel tank, I'm not sure what the fuel tank situation is on yours, seeing it had a bigger Briggs there would not be a lot of space under the bonnet. I had to make up a fuel tank for a mate to fit up inside the front of the bonnet when I fitted a 13HP Chonda in his.
