The Oregon 91-144 is 20.5” long, 3” wide, .203” thick and 1/2” offset . The ones I got from an Massey Dealer are 20.5” x .25” x 2.37” . Not sure of the offset. Would there be any issue if these were put on a gc2300 mower deck? Would they fit ok?
/ Will Oregon 91-144 blades fit and work on the 60” mower deck of a MF GC2300?
If the bore of the mounting hole is the same, and your deck doesn't have a special holder or stiffener - than they very likely would. I've put the wider blades on ZTR decks and they cleared fine.
