Spotted a mower for sale recently that the chap couldn't get going, he was unsure of the make of the mower, so I did a deal over the phone seeing that it had a late model Chonda on it so it would be an easy fix. Got the mower home and could just make out it was an S/B on the plate and after a bit of research I think it is a 14'' Twin rail. Cosmetically a bit average but solid and looks like its all there except original catcher and engine. Was there a couple of different engine installed on this model or is there 1 specific engine, and if so which would it be ? The little unit Fly's with the 4hp on it, anything above quarter throttle has you in a canter behind it ! I love the split roller on it....... like it is hard to turn being 14'' The plate numbers are 45 41897 45 0407 Cheers wce
