I know the A series tractors are the lightest weight and C's are heavier. So I guess it depends on what you'd be doing with them.
Great info and good point Ben.
Richard, mixed results here.
I know our 4250 used to start better with the tank versus block heater and when it's really cold we plug 'em both in.
And then blow a breaker....grin
The 656 even has a fancy transmission heater but of course we never use it. Some mornings it really whines but just it let it sit and warm-up for 10-20 minutes and she's good to go.
Biggest difference maker in IMHO is placing a cardboard 'wind shield'(overnight) on the windy side of the engine.
A big heated shop would be nice....
