My local walker dealer was telling me today that i needed to either trade up to a newer mower or sale my walker and buy a new one! It has approx 820hrs on it. He says it is about to start "nickel and diming" me. Hm... Kinda makes me think, if this thing is only good for 800hrs, then ill jus sale this thing and replace it with something different. Anyways how well are yalls walkers holdin up?
