Garry,
my thoughts on this item, and my friend's here local (who used to be a Wheelhorse dealer) are that the GT-14 was badgered as the 1ST GT-
-Garden tractor--but by 73==You will find many parts on the first Gt-14's
(ie--the two spoke steering wheel, for one) to have been incorporated from the larger/older tractor s before them--950 series and 1070's.
.........other brands were doing the same thing, so they moversd on to the "D" series--bigger/heavber/more horsepower, etc.
My best guess-
[-I hope that old Carl Bowles (old W/H retiree) will again be up there in June at the Wheelhorse show--so I can hang w/. him for awhile, and listen to some true old tractor lore. Hope to see Steve and the guys, also.]
