how many CCA do i need?

[GMG]

just got a used (not sure of year) t1400 HST (im assuming the 1400 means 14 hp?) i think the battery is shot, i bought a new one from a hardwear store here, its got 235 CCA, it was the biggest one they had. but still doesnt start the mower., the one i pulled out had 335 CCA which seemed like overkill, but maybe im wrong

The bigger the better when buying a battery.

235 CCA is more than enough to start a lawnmower.

Something else is wrong.

Agreed

The bigger the better when buying a battery.

Can you be more descriptive of the symptoms? "It doesn't start" is not very helpful.

Does it turn over? If so, fast or slow?
Does it just click?
Are the cables in good shape? Terminals clean on both ends?
