I have an Exmark Metro 17hp walk behind mower. I'm having a problem with the wheels squeeking. It doesn't sqeek when I start mowing but after about a half hour or so, it starts a loud metal-on-metal squeeking sound that drives me nuts. I've taken off the wheels and lubricated the axles (what a dumb place to put the grease connection), but that doesn't help. It seems to have something to do with the brakes but I'm not sure about that.
TIA, Robert
