You’ll like the LS. I’ve had my 347HC since 2021 with no regrets.
Couple things:
You can add a grapple by running hoses from the green rear remote to the loader. Run it along the top of the blue loader frame and use heavy zip ties. It saved me $1000 on a third function kit. You need a grapple, long hoses, and a mount bracket for the loader.
You must keep the AC condenser in front of the radiator clean and clear of dirt and grass. This means blowing it out from behind after a day of mowing. I use a strong leaf blower most of the time. Sometimes, a wand on my air compressor between the radiators (look up a Radiator Genie), and once in a while I blast it out with a garden hose to wash the crud from between the fins. This is not an LS problem, but applies to any tractor with AC. It needs to be clean.
