    Just a heads up. The key was left on our new XS mower long enough to kill the battery. After jumping it and mowing for an hour or so the battery was about stone dead. The mower was not charging. It turns out there are two 20 amp fuse in the charging circuit that will blow if the charging system has to recharge the battery when it is to low. Once the battery had a charge on it and the fuse was changed there were no more problem.

    Just another heads up. Never jump start any lawn and garden equipment with a truck or car with the engine running ! The 65 plus amp alternator on the vehicle will put too many amps through the equipment electrical system and blow all sorts of things.

    Do you know why the fuse blow? I do.

    The charging system on lawn mower type engines is meant to keep a battery up and replace the power used and top run the on board systems. It is not meant to bring a battery back from the dead. You will blow a fuse 99% of the time trying to charge a battery that is completely dead or close to it. It just is more that the system can handle. When you have a battery that dead that is when you get out the battery charger and plug it up. I see this all the time at the shop.
