Last night Doug brought over the ride on mower that we are going to keep at the house. The weeds are getting pretty tall so I thought I would chop them down tonight. Well, I got about an hour into it and then the mower seized up. So Mert and I took at look at it, and we thought it was the drive pulley bearing after checking all the obvious things, like it being out of gas and such. So we called Doug and had him check our work. He had the thing out in about 10 mins (I'm pretty sure I can put it back) and sure enough the bearing were shot and so now we have to get new ones before we can get back to weed patrol.
