The 16.5HP Twin on my tractor cranks a lot easier than the old 14.5HP single I/C did on my old tractor.

And mind you it's not the size if the batteries that matter like Amp, but rather the CCA of the battery.

How much juice it will give you at 0F for 30seconds.

Yup

Always best to get the biggest Cold cranking amp capacity you can, especially in a colder climate.

those opposed twins usually have a hard time starting with any thing less than 350amps. if that doesn't work than its the starter. mine had the same problem, even tried jump starting it off a truck with 2 800amp batteries, so I got a new starter from choo choo's for 90$. works great now.
