Picked up a Sears Platinum Group 35 last night, 750 CCA and one great warranty. I've been running these on all my vehicles and they have performed better than some of the popular AGM batteries on the market. I need to test fit it, but the advertised measurements had it just barely fitting.
OK, SG, got to use small words with me;-) The negative battery post was strapped to the engine and I wasn't going to do anything but replicate that. There is a Delco alternator on the front left/driver side of the tractor that is the shiniest part on the tractor and has obvious aftermarket brackets, hence the hesitation on the 12V vs 6V question. So from my limited knowledge on this, the tractor is set up as a negative ground, right?
