We have a BCS scythe, just bought a newer rotavator (S/H) thinking we could just swap the blade, wrong model! so we either get an adaptor or buy a scythe for the newer machine.
I like them, the old scythe has worked well over the years, OH likes rotavator, pity ground was still wet when he worked it, made a real mess. but did the job, lots of attachments, plenty of power for the work.
