Hi again
mikeo, I would agree with Grumpy, on first glance, I would say that the 20" machine would be the best to get up and running after some TLC.
The Briggs engines, both being 3HP is a good thing as you can choose which is the better engine and swap them over if necessary.
The plan of attack I would choose is to:
(1) Remove the engine on the 20", inspect and post pics of both engine deck rails....(we will be looking for cracking)
Check and inspect cutter clutch components for damage or wear and replace as required...(but I have a feeling all will be well there)
(2) Remove the drive chains, 12 tooth engine sprocket and discard, remove the double cutter sprocket and discard.
(3) Purchase new double cutter and 12 tooth sprocket and new primary and secondary chains.
(4) Remove cylinder reel and soleplate with the bottom blade still attached and take both to an engineer/machinist for sharpening.
Purchase new cylinder reel bearings and discard the old ones.
(5) Grumpy will kindly help you with any engine issues, be sure to follow his advice carefully and you will have a good result.
Looking forward to your further posts,
