I have a late model (early 80s probably) set of New Old Stock 38” deck kits (came in a crate from a closed down dealer who ebayed them), complete with undercarriage for wideframe, muledrive, belt, and manual. I also have a 149 that I’m about to get running again. The 149 came to me running good, but without any deck, mule drive, or undercarriage. So, I’d like to put one of the 38” deck kits on it. But, the mechanical PTO on the 149 has the 1/2” belt size PTO, and the 38” decks have 5/8” drive pulleys (and idlers on the mule drive). From a previous forum topic, I’m thinking that I can’t put an electric PTO (which had the 5/8” belt by default) on my 149’s Kohler (no PTO mounting holes on the Kohler, until after the 1x9 series). So, I think it makes sense now to change to 1/2” on the idlers of the mule drive and deck main drive pulley. Anybody gone thru this line of thought and have strong feelings about a path? Also, is there a really bullet proof trick to freeing up the main pulley on the deck spindle? It seemed real rooted to it (even though it’d never been put in use) back a few years ago when I last tried penetrating oil and leveraging under it with bars. I’d like to go ahead and be hunting a path to a 1/2” pulley for the deck.
