Hi MM,
the 5 and 8hp motors have the 1 inch shaft ( that is any with the ride on Briggs bolt pattern, the small push Briggs motors have a different pattern) 30 inch is what these ran, they may have built some a bit smaller, not sure. Greenfield built them in 26,30 and 32 inch. I think their rear engined ones were 5 hp and the front engines were 8 and 12. They may have fitted some bigger ones in the Evolution models
