I have a 18.5 Briggs and Stratton in a MTD Yardman Ranch King Tractor, I need a new battery but the last one is missing... no one in my area can seem to give me a straight anser as to what battery or specs to use.

BAttery case # U1L or U1R, 250 amps or better

And if you use 250cca (cold cranking amps) battery, get ready to purchase a new starter. To give your starter longer life, use at least a 300CCA battery.

Than why does my instrucrtion manual state just that 250 or better? My is a 20.5 hp twin cylinder, with a 275 amp battery.

Because if you think about it, they sell you the lawn mower, then they really make their money on the parts. That's why the manual calls for 250cca battery. Think about it. I am just telling you what I know from years of experience and yes we have sold a many of new starters to customers that had a battery that yes was cheaper but only had 250cca. Do as you wish, but I would highly recommend going with a 300cca battery. The briggs starters are around $130.00.
