I hate to bust your bubbles on the A/C unit for your lawn mowers, but it makes no difference if it's a JD, Sears, Toro, Cub Cadet, etc, etc, if your tractor is 30 HP and you have a seventy two inch deck, your grass is a tad bit tall, your charging system is at the most fifteen to eighteen amps. The clutch on the compressor is about five amps, the cluth for the deck is about the same. NOW, we add a blower for the evaporator and we also add a fan/blower for the condensing unit. For both of those, we are at about twenty five + amps, ....ooops, we just crashed the charging system. So, now it's off to the parts store for a retro fit GM sixty three amp alternator. NOW, much to your suprise, that alternator requires about seven HP, along with the compressor (an axial unit draws about eight to twelve HP) we are up to about sixteen HP. The operating system of a mower (transmission) uses about six or seven HP to propel my fat butt around. Now, we are up to about twenty two Hp. This leaves about eight HP to run a seventy two inch deck. You swith on the clutch that powers the deck and head out to mow. The blades hit the first few feet of grass and all of a sudden, the engine kills like someone stuch a crowbar inbetween the crankshaft and block. We sit in the cab, (now getting warm) and say to ourself, WTF? My push mower with a twenty one inch deck has a six and one half HP engine .... you might be able to reduce your deck size to about a twenty three inch deck and stay cool and mow. OR, you can go buy a fifteen ft Bush Hog batwing mower.
