Blows fuse after mowing for a while

How to Identify and Fix Common Gardening Problems ?

We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :

It is very likely there is a short somewhere in the system. If not in the wiring, there could be an issue with the fuse box. This is unlikely if you are not having issues with other circuits. The starter can also cause this to blow.
Why did the fuse blow? A fuse may blow from a temporary electrical surge in the wiring harness, such as when the battery is improperly connected. A fuse may also blow as a result of a direct electrical short somewhere in the wiring harness or electrical system.
A high-resistance connection at or near the main fuse heats its fusible element by thermal conduction to its melting point. The heat injected into the fusible element causes it to blow.
Unplug all appliances on that problem circuit and switch off any immersion heaters (if you have one), boilers, outside lights etc. Switch the tripped switch to the ON position and plug in the appliances one by one until the trip goes again. If it does trip again then you will require a new appliance.
Car suddenly stalls while operating: One of the most common symptoms of a failed ignition relay is a car that suddenly stalls while operating. If the ignition relay shorts, burns out, or otherwise fails while the engine is operating it will cut off power to the fuel pump and ignition system.
Improper modification is one of the most commonly seen problems. The most common of these is tapping more than one conductor from a single connection point.
A Short Circuit in the Electrical System:

A short happens when there is a poor connection between two conductors supplying electricity, which then causes an overload to the circuit. This overload causes the fuse to blow to prevent the wiring from overheating and melting.

There`s a reason your fuse is blowing and it`s something on the load side (whatever the battery is powering) drawing too much current. Either your load is too big for your battery or something in the circuit is shorted and drawing current where it shouldn`t be.
Connect one headlight to the battery`s positive terminal and connect the other headlight to the battery`s negative terminal. Turn on the headlights and check for an electric current, sparks, or heat. If you see any sparks or heat, then you`ve likely got an electrical short circuit on your hands.
They occur when a low-resistance path not suited to carry electricity receives a high-volume electrical current. In simpler terms, short circuits happen when hot wire touches a conductive object it`s not supposed to. The result of a short circuit can be appliance damage, electrical shock, or even a fire.
The fuse used on most of our riding mowers is a 20 ampere, 12 volt, automotive-type, two-prong, flat-blade fuse ( known as. SAE ATC® style).

fuses. Can you please help!
ANSWER : Go to a smaller fuse, but it sounds like the PTO is shorted somewhere:http://www.google.com/url?sa=t&source=web&cd=4&ved=0CCoQFjAD&url=http%3A%2F%2Fwww.mymowerparts.com%2Fpdf%2FCub_Cadet%2FCub_Cadet_Service_and_Repair_Manuals%2FCub_Cadet_RZT_Series_Zero_Turn_Service_Repair_Manual.pdf&rct=j&q=Cub%20Cadet%20RZT%20mower%20manual%20pdf&ei=sWbITayPEoSbtweSvqmSBA&usg=AFQjCNEAreyaCVOyDN0SaP-6A0cxzha8bA&cad=rja

I have a cub cadet mower 2166, It wont start it keeps blowing the red wire fuse, I thought it was the battery so I bought a new one and cleaned the cables and ground wires, and I didnt see any loose or broken wires. as soon as you turn the key on it blows fuses please help
ANSWER : Hi,
There is a wire shorted to ground (metal) somewhere…check all the wiring for a bare spot somewhere… this is causing the short…repalce the wire and you will be good…
finding the bad spot is the hard part…

Turned pto off when finished mowing then turned it back on and it does not come on
ANSWER : Check the wiring to the PTO first. if it is good either the PTO or its inline fuse has failed. try the fuse first as it is much cheaper. if it just blows again you are back to replacing the PTO.

My ride on tractor ( husqvarna yth 1848 xp) blew a fuse and I replaced it and it ran for 10 min, then stopped. AS sson as you turn the key to the on position it blows the fuse again. Seems like there is a short somewhere. Trouble shot for sometime but can not get the fuse to stop blowing.
ANSWER : Follow the wire from the fuse and you should be able to find the short. if not start unplugging lights and all safety switches and i am sure you will find it.

My Toro LX425 keeps on blowing 20 amp fuses when I am mowing the yard. Why is it doing that?
ANSWER : A fuse will blow if: a positive wire is being grounded to the frame or two much current is being passed thru it.

Why does the fuse to the PTO system keep blowing?
ANSWER : Because there is a short between the fuse and the electric clutch or a dead short within the electro-magnetic clutch.
