It depends, the 2520 does not have glow plugs and can be a bear to start here on the east coast when it's cold, the 2305 never once gave me an issue. The service guys at the dealership do not care for the manifold heater setup on the 2520, I sure wish I could change it as I don't care for it either.Hey 1972
Welcome to MTF and congrats on the new tractor. For what it is worth the Yanmar seems to start no problem here on the East Coast without a block heater. When I asked my dealer about it he said they rarely install them here. The 2320 continues to be a popular model according to my dealer.
