After removing the broken engine, the first thing to do was rebuild the chassis, which had suffered from years of use. Afterward, attaching the adapter parts was straightforward and easy; once aligned, the engine fit perfectly as if it were already an integral part of the machine. All that remained was to connect the throttle cable, attach its control, and reinstall the belts. Since my drive pulley was broken, thanks to Mr. Carr's excellent advice, I was able to adapt an F400 pulley to my F600 by making shims to align the belts. Now, my rototiller is ready to get back to work with minimal cost and effort.
