This thread is VERY interesting!! The responses are all over the place.
OK, only my longarn has a name - "Beth" - because it was SUPPOSED to be a Tin Lizzie (Lizzie = Elizabeth = Beth). She actually is a Viking MegaQuilter 18x8 (same thing as a Tin Lizzie). My other sewing machines (Viking Designer I and a Singer serger) don't have names.
However, all our vehicles and tractors have names:
Vehicles:
Ford F350 is (understandably) Ford
Camaro is Red (and she is)
Ugly Alice and Betty are both Saturns
Tractors:
Massey Ferguson (biggest one) Big Mama
MF 274 is Mike (the name of the guy we bought it from)
MF 165 is Granny
1943 Farm All Super A is Matilda
and a little yard tractor/lawnmower is Ernie (the name of the guy who gave it to us, dead as a door-nail - we fixed it, runs good)
