Does the husqvarna model YTH2348 have a fuse

SOURCE: I have a Husqvarna yth2348 lawn tractor. It starts fine, but

You didn't mention how long it worked with the new battery so here are a couple of things to try. Using your car/truck and a set of jumper cables if you have them, see if it will start,just be sure that they are hooked up properly.
Use a volt meter and test the battery. It should have at least 12 volts. Get the engine started and at full throttle, again test the battery, it should be showing 13 to 14 volts indicating that it is charging. If not, your charging system is the culprit. If charging system is good, then it may well be the starter, Remove the starter and take it to a lawnmower repair shop or do-it-yourself auto parts store and have it checked. The starters are VERY expensive depending on the brand of the engine so you want to be certain that it is bad before buying a new one.
If all this is good and/or it sounds like the engine makes about a half of a turn before bogging down and not starting, it could well be that your valves need adjusting or in worst case scenario, your automatic compression release inside the engine has failed

you may hav a bad alt. problem with the mower dying when you engage the pto is most likley a bad sensor or wire unplugged on the seat sensor.the way it works is if the blades are turning and it dosent sense you being on the seat the mower shuts down.this has been standard on mowers for quite a few years now. it keeps the blades from cutting you up if you fall off the seat while mowing. as for charging i would try cleaning the battery connections and get the battery checked first.

try unplugging the pto then start the mower next engage the blades and see if the fuse blows if it does the problem lies in the mowers wiring if not the problem lies in the pto. hope this helps

You have a dead short in the circuit for that fuse. Check for a pinched wire, or a wire rubbed thru a touching metal.

Testimonial: "very helpful with the problem"

SOURCE: blades making a bad noise

Well I would say you have a bent blade, a blade has a loose connection to the bottom of the mandrel, or a mandrel bearing is going out. Visual inspection will reveal much, just look under the deck. A bad mandrel may appear to have "runout" when viewed from the top while spinning as contrasted with a good mandrel. Viewing the one in the center while deck is working is going to be a challenge. If you decide to replace a mandrel, do yourself a favor and take a picture of the deck belt before you take it off so you know how it goes back on.
