I have a Troy bilt mustang xp. I recently had a problem with the fuse blowing that’s connected to battery. Battery wire was freyed along with two wires going into a black box. Replaced all and now the mower thinks the pto is engaged when it isn’t

SOURCE: LAWN MOWER WILL NOT START

The compression relief valve is not working. Pushing the engine past top dead center and turning the key works after a fashion. Keep the battery fully charged. This is a design/engineering fault in B&S engines which they cannot fix. It is in all of their engines. Most do not malfunction but those that do, do it all the time. I have had the compression relief valve replaced and the valve settings set to allow the valve to function (it uses the exhaust valve by holding it partially open while starting) but it still does not work properly.

Skip the below portion if you don't want to hear a negative view of B&S engines.

The engine problem resolved itself today (12-10-10) when it threw its rod into the cylinder wall. B&S engines power a huge number of the riding mowers in the US. It is difficult to escape them when buying a mower. Use it on more than a postage stamp yard and B&S will claim you abused it.

SOURCE: eXmark mower blows fuse when deck is engaged.

try checking the wires from the switch that engages the mower deck. if there is a wire grounding out sumplace when you kick it on it will keep popping the fuse no matter what. id say its a short.

SOURCE: I have a troy bilt riding mower blades will not engage in the 1 or 2 deck setting

There is a spring attached to a tensioner that probably came unhooked while changing the belt. Higher deck settings push the deck backwards enough to spin the blades, the lower setting need the spring tensioner to take up the slack in the belt.
