The spec number on the CH20 will determine how it was setup.  With a picture we can give a little beter idea of what the engine might take to get it into the Cub.  I'm not real familiar with the exact size of a command so I can't say for sure but it might require the removal of the side tins to ft it in.  As far as hooking it up to the tractor itself, anything is possible with enough fabrication.  Just depends how wild you want to get with it.

 

Post a picture or two of the CH20 from both the crankshaft side and the flywheel side so we can get a look at it.  Also the spec number or a picture of the tag.  As far as rotation, Cub Cadets ran the transmission from the flywheel side and the pto from the crankshaft side of the engine.

Hope it helps.    Rick

Thanks for the response the engine tag says model CH20S, Spec no. 64510, serial no. 2225911367 as far as fabrication I own a golf cart sales and service shop so I have welders, torches, plsma cutters, benders so fab is not a problem I will post some pictures as soon as i figure out how to get them up here. Again the motor came off of a 1993 grasshopper 720k

I saved a copy of that pic. I'll make it a PDF and upload to the Cub Manuals section so it's not lost.
