I have a Task Force model #25143 electric mower (corded) that suddenly stopped while I was cutting some grass that I admit was probably too tall. I have had no previous problems with it whatsoever since I bought it new last year. After some searching I found out that it had tripped the breaker (was plugged into the GFI outside the house). It's only a short cord--an extension must be used. I bought a new one last month, but tried two other ones just to be sure--no change. I tried using a different outlet--no change. I tried using an inside outlet and promptly tripped that breaker as well. I checked the blade, it spins freely, there was a small amount of grass on the shaft above it, I removed that. There was a lot of cut grass on the underside of the deck (it's a mulching mower) and I removed all that going to the side discharge and the chute where the bag would be. I took off the cover to the motor, there was some grass and dust in there, I cleaned it all out. As for the connections, they are still clean as a whistle--no rust, corrosion, burning, fraying, etc. they still look new. I was looking for a fuse and couldn't find one, checked by the motor and in the handle where the switch is. After all this it still trips the breaker so I'm thinking there has got to be a short. The plug side of the extension cord was warm. I found an answer that said use a multi-meter and I suppose I could go buy one but then what do I do with it? I don't know what I'm supposed to hook it to and I don't know what any of the readings would mean. I'm too low on cash now to pay for repair or buy a new one and where I live the grass needs to be cut almost 2x a week--any advice? How can I find the short or is the motor gone? I also read about motor "brushes" but don't think I saw any not that I would know what they look like anyway. I included pics of the switch and the motor.
