Hi there, Yazoo kee, with 18hp intake Briggs, today I was mowing and with blades engage the motor wants to shut-off, if I disengage the blades it will still run, I did shut-off the engine to take a look at the blades and everything since fine, but when I turn key to start, it was dead, just a click noise, when I arrive home today , I check the battery and it was gone, I tested and it is completely dead, here is my question, the electric clutch to engage the blades does it needs power from battery to work or it can work with a dead battery and run just from the engine? I will really appreciate any help
