Blades won't engage..just bought this mower a month ago. we changed fuse, and everything else seems to work properly. what should i do next?

SOURCE: Knocking in mower deck or belt clutch when engaging blades, motor bogs / slows down

YOU MAY HAVE A BENT BLADE OR EXESSEIVE BUILD UP UNDER THE DECK

SOURCE: I have a Husqvarna Yth 180, the lawn mower shut

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

SOURCE: Mower blades willnot engage

make sure the battery is fully charged, check all electrical connections and clean them with vinegar and rinse well with demineralized water afterward.

there is an electric clutch, also called a PTO, which is on the lower end of the motor's drive shaft. If you look underneath the mower in the front you will see it, a belt is on it which goes to the deck and spins the blades. The PTO has an inline fuse which could have blown, unfortunately it is generally caked in old cut grass, spilled oil, and belt wear residue. You are going to have to get some light down there and take a long look at the PTO, find the wire coming from it, and follow it until you feel a bump in the wire, like a cat being digested inside a snake. Clean the bump well and you will see that it is really an in line fuse holder and you can take it apart and replace the fuse if it is bad. Having said that, when a fuse goes, it goes for a reason and that is generally the PTO is failing and shorting or drawing way too much current. The fuse is a safety valve. But it may get you through the cutting and you can call a mower repair shop and have them replace the PTO.
