Re: (ET) mower blades

["Steven Naugler" <snaugler earthlink net>]

Larry and others,

The only two blade decks I have seen use the larger diameter motor, 
although
that may have been because (I think) they are shorter in height and
clearance under the tractor may be an issue.  I have seen a few three motor
decks with the larger diameter motors, but most have had the small ones.
